Topic: 20 Rides 100miles or more, in 2020..

Wel, I had to look at the 60 foot times forget Rocket 3 ., looks like some of the cb750s we raced were still pretty good in their 60 ft times... looks pretty similar to the Rocket 3..
 I saw 60 ft for Ticket 3 between 1.61 and 1.8 seconds...  most if them were doing tge 1/4 in 11.6 to 11.8 with 1.8 60 ft times... I figured getting that weight going is a lot of work.

Ha ha, keep dreaming Frank, the Rocket III makes 147 foot pounds of torque from 2500 RPM, by the time a CB750 (the same cc's as ONE cylinder of a Rocket III) has made up enough steam, the Rocket II rider is collecting his time card. Of course, drag races are only one example, a roll on race from 60 MPH is even more embarrassing as the Triumph "Rockets" away from the CB750, doing 100 MPH @ only 4000 RPM.

The good thing is that the Triumph rider will have parked his bike and bought a round of drinks by the time the CB750 rider arrives at the bar. That's OK, there's 40+ years of evolution between both bikes, and I enjoy both equally. There are much faster bikes than Rocket III's now of course, but it's the newest bike I own.    

[754]

I was talking about 60 ft times , not 0 to 60 mph.
 This is a common thing with people that don't drag race... they think their bike is the one in the magazine  test ... and its not that it isnt.... it's that it isn't with YOU on it..  at any rate, it's usually the case..
 If you went to the drags , and timed your bike , you will likely find this out.... and its not like you can't be a lot quicker.l but it will take a bunch of practice to get there. And that you are not Pee Wee Gleason ,  nor the Cycle World test rider
 There is a few bikes on this forum, CB 750 based that have quicker 60 ft times than a Rocket 3...

That Triumph engine fits a car!
Too many bad car drivers and animals that makes me worried when riding 170-210 kmh for a longer period of time my K6 enter rather quick.
Nothing for modern bikes that continue.
I think my K6 can do 220kmh according to speedo that do not show much wrong, around + 2.5% when checked radar/laser signs.
If leaning forward, less wind brake

I smashed a fullgrown hare once in around 140-150 kmh, no time to think brake, a fuzzy brown shape jumped into the bike from side of the road hidden in the ditch.
It died almost direct when hit by engine + right foot peg. No wheel involved which had changed the outcome. Full control of bike. My K6 early 80's.

But compare with other modern 4 cyl bikes revving ~14000 rpm.
How much power at 8000-9000 rpm where an old modified CB750 often get its max? Not that much over 100whp?

Possible to keep them behind for a while until they get out of the chock not passing that old bike yet

Except the multi liter Rocket III

[Terry in Australia]

Ha ha, here we are on a thread about riding at least 100 miles and Frank is quibbling about 60 foot times? 60 feet from my driveway is my neighbours house?

In the REAL world, away from our computer keyboards, we ride on the road, and if we have any friends, we have roll on races with like minded souls, we don't go to the drag strip on Saturday night to see how fast we can go 60 feet. Some members here do have quick CB750's, some with worked engines that'll pump out maybe 100 BHP but I know R3 owners who have mildly modified engines that reliably produce 250(+) BHP, and they're probably just a tad quicker.

The CB750 is a wonderful motorcycle, I've owned over 20 of them since I bought my first one new in 1978, and own 4 at the moment,  but comparing them to a modern bike is like comparing a Corvair to a Corvette.

I hit a Kangaroo on my BMW K100RT in 1991 Per, luckily a car driver had hit him first, so I just rode (jumped, pretty much) over him @ 160 KPH. I was riding 1100 Miles (1760 Km) to Canungra in QLD to do an Army promotion course, so it was dark and I was tired after a 600 mile day. I pulled into a motel, checked in for the night, and parked the bike outside my room.

I woke up in the morning, got dressed, walked out to the bike and realised I had Kangaroo guts all over the radiator and under the bike, semi-baked on, and the smell was unbearable. I rode around to the local car  wash and hit it with the pressure washer, which removed most of it. I was only happy that he wasn't standing up when I hit him, or I probably wouldn't be here to tease Frank.

Kangaroo, hare on steroids

Well it is after all a forum for CB 750 Soho  other Honda SOHC here.. perhapsTerry  may want to start his own thread, about the Rocket 3 ... it could be called Praise The Lard...

 Even Terry himself said it in post #3... let's keep it to Sohc4,s..

Ha ha, looking at your avatar pic there Frank, I can see that you’ve knelt at the altar! But I’ll post pics of my F2 and K0 as well as all my other bikes, it’s nice having more than one marque, so I’ll be posting pics of all my rides, regardless of which of my bikes I’m riding.

Like me me there are plenty of guys here who own several different bikes, so you’ll just have to accept that it’s all about the ride, and less about the bike we did it on, as you grudgingly agreed in your earlier posts the aim of this thread was to get people out on their bikes and share their rides, and I for one am enjoying it immensely.

[Robbo]

Well you know what they say...timing is everything.

Ride #16 113 miles on the...cough cough...Yamaha RD250.  I hadn’t been out on it for some time so with the weather getting cooler, this was a chance to give the 2-stroke a run. 

I went north to Forks of the Credit.  Surprised to see no bikes in the parking lot of the local coffee shop but it was cold with a gusty wind.  I continued on north of Orangeville to ride Hockley Road.  At some point I rode past a number of people out of their cars snapping photos of what looked like an abandoned motel.  It took my slightly frozen brain to realize it was the motel from the tv comedy “Schitt’s Creek”.

I managed to stay ahead of some ominously dark rain clouds and had to dodge a grouse crossing in front of me.  I’ve seen a few grouse and a group of wild turkeys on my recent rides.

Didn’t seem that bad when I checked the weather app and set off after lunch.  It sure was colder than I expected...or maybe I’m just getting older .

Robbo......you did better than me! Went out on a few errands (including a haircut in case we go into lockdown again). 30 miles on the K0 and I was COLD!! From now on it’s the KLR650...... hand guards and a bit of a screen start to matter in November.

[grcamna2]

Robbo,you ever consider slapping an RD350 top-end onto your RD250 ?

Funny you should ask...I have one in a box in my parts stock (bought it about 15 yrs ago).  To be honest, it runs nice so I haven’t had reason to swap over the top end.

Bonus ride #27 105 miles, 62f
 I got another bonus ride in with a break in the weather today. The sun was shining when I began, but it didn’t last for long. Tomorrow is supposed to be a different story, as a cold front is coming through soon with some amount of accumulated snow following. The photo is at Delhi, on the Huron River. The iron bridge was restored a few years back. I think the piers were eroded as well as the iron. The bridge was out of service for a year? while the piers were rebuilt. Hideous traffic signals were added so only one driver at a time will be on the bridge. The bridge made 100+ years without traffic signals, but not so in our modern world.
 My battery has recovered, is holding a charge @12.77, and has plenty of cranking power. I never dreamed it would recover after I left the key on for 48 hrs (kill sw off) and the neutral light and oil pressure light drained it to near zero.   I tried the smart charger first but the tender didn’t show charging so I put the old dumb charger on and it came right up to 12v within 30 minutes. I resumed with the battery tender and it came back to full overnight. It is a 5 yr old Scorpion.
 I dunno if I will get another ride in, there has already been snow on the ground, so I shut the petcock off and rode another mile +/- then bolted for the driveway when the engine sputtered. The carbs are drained, the tank is full.

Good looking brown bike!

I had hope about a ride last week when temperature was OK, but too wet. The cold has now arrived with some snow.

It will take time to next end of March if lucky with the weather.

Yes, time to think about off-season upgrades: the front tire BT45 has 12,000 miles and unusual wear, the front brake needs a service, maybe a new chain, Maybe service the starter clutch.

I'll take out the engine, reseal cases, change base gasket, probably another head.
I'll see tomorrow how much stretch my CCC primary chains have and if I need to replace them too. Change chain tensioners. Clean engine while apart, green crank bearings hopefully OK.
Change swingarm (refurbished need new shock rubber bushing first), new drive chain and sprockets, rear tire...
Change fork oil when engine is out.
I'm already tired!

[Kevin D]

You are a very hard-working and ambitious guy PeWe, Me not so much. I like to ride my Honda more and I had hoped to never remove the engine again. It’s been 13 years and 30,000? miles. The engine runs very well, doesn’t use oil at all, it’s just beginning to stain the top cylinder fin after a hard highway run. Not a big deal, I can tolerate that. Maybe Frank’s frame kit and a top end service down the road. Or not.

[PeWe]

I have to...
That bike has done many rides this year, total a little bit more than 10.000km.
I replaced head and cam less than 2 months ago to finally enter +100whp on dyno
I have spent a lot of time rejetting carbs!! Must be a world record!!

My other bike CB750 K2 need nothing, only charge battery a few days every month.
But it got new pistons and fresh bored cylinder a few months ago plus more replacements.

I look forward to rides, tire replacement and standard service only every 4000-5000km.

I'm lazy compared to Terry!

[Terry in Australia]

Thanks Per, Iust got back from a 100 miler on the Effing F2. I replaced the clutch and springs last week, brake master cylinder, top brake hose, speedo and tach and installed new Oury grips yesterday, and apart from problems with both gauges, the bike ran great.

I stopped to take a couple of pics, and when I turned the ignition back on, nada. Poop. I checked the fuse box, and I'd blown 2 fuses, which was weird. It was lightly raining, so maybe that was an issue, but anyhoo, I replaced the fuses (thank God I had spares) and when I got to the next town that had a gas station I was able to buy a pack of glass fuses that are too long for the stupid little Honda fuse box if you want to put the lid back on, but it would have gotten me out of the sh1t if I blew any more fuses, which I didn't.

F2 ride 22 Nov 2020 by Terry Prendergast, on Flickr

So I blew a couple of fuses, got soaked, but then when the sun came back out it almost dried me out, and at least my 30 year old leather jacket got a nice wash, and I had a great ride. I got home in plenty of time to do some more work on the K0 build, so all in all, a great day.

Kevin, that "unusual tyre wear" issue seems to be common on Bridgestone BT45's, in fact that's why I stopped using them, on mine they tended to scrub out on the right hand side of the tread. I read an article in a Harley magazine and the tech editor made some sense when he explained that depending on which side of the road you ride on, excessive wear on one side or the other is caused by the camber of the road.

Over here where we ride on the left, right hand turns are longer than left hand turns, and the road slopes down from the centre, so apparently that contributes to the tyre wear on the right hand side. Also, from memory, the BT45's are "dual compound" tyre, (softer on the edges and harder in the centre?) so that could account for tyres scrubbing out prematurely. Having said all that, 12000 miles out of any bike tyre is quite remarkable.

I've put Stinko 712's on a couple of my bikes now, they're around half the price of "Brand Name" tyres here, and I think they're great, I was putting the old F2 through the bends in the wet this morning with no hint of slippage.

Thanks for that info Terry, and yes it’s the right side of the tread wearing, also the scalloped wear is turning it into a knobby. I gave it only a 1 minute look and haven’t yet taken a photo. In the past I have been a 2 rear 1 front user but I have a fairly new (one season?) BT45 on the rear. Gotta figure that out.
 I’m generally riding on the right side of the road, except when passing. There’s not enough curves around here to wear the side of the tread. I have never done a straightedge alignment and I use the swing arm scale to set the rear wheel. Hondaman custom fitted lifetime bushings in the swing arm fitted with Hagons, all original parts in the front shocks, tapered roller bearings in the triple tree, newer wheel bearings.

Kevin, I was told by long time shop owner that this type of wear was associated with leaking fork seal, old fork oil(its really only good for a few seasons), weak front springs, so maybe just some light front fork service is in order.  I have had some tires wear like this and others not, and have not really put together coherent data on what bike, what service done, what tire to know any different.

+1 on two rears for every front

[BenelliSEI]

I think I’m done. 4” of snow today and the damn sand, gravel, and salt trucks will be out!

[RAFster122s]

Shocks that are worn cause the scalloping or cupping wear in the tread. So, front forks need attention with oil and likely new springs (they wear out quick ...at least  OEM do). You will appreciate how much nicer the front-end is after doing a service like that...

Haha, many many things on my CB are now 50 years old 50 years old. I have replaced the seals one time, long ago. Not leaking now. But never the springs or the sliding parts. I’m using ATF, 7oz?
I can spot bad shocks on other cars driving next to me on the highway, by the bouncing tires. But my CB is not bouncing down the road.
I found a photo that I posted in 2011 with a similarly worn BT45.... I gotta get a photo of the current tire and put them side by side, but my CB is on the back burner just now with a Big Family Event.... a new granddaughter.

 Think I will start a thread in the tech forum when I get the new photo, and take my tech problems there. I’m likely finished at 27 rides, all documented here. Frank, your 20 x 100 challenge dovetailed with my usual country rides, and once I figured out that Honda riding was allowed and reasonably safe I was good to go.

[Terry in Australia]

Yep, scalloping isn't just caused by one factor, and the problem with BT45's is often discussed on several forums and FB pages I am a member of, so I'm guessing that it's a problem with that particular tyre. At Dave's advice I switched to Pirelli's and haven't had the issue since, but same/same for Michelins, Metzlers and Stinko's, they're all pretty good.
