Defied the Governors order yesterday and picked up a little thumper for a Pandemic Project. Titled 2002 Honda XR200 for 400 bucks.Supposedly ran when parked quite awhile ago.Got it torn down already and the carb is quite dirty. Hopefully an easy project. Don't really need it but something different to do and get out of the house and give my wife some "her time"  ;)

Looks good Eric.  Seeing you and Dave with these off road bikes is making me want to get my TS250 back in service!

Definitely I would want to start a CB casting thread here that would be awesome

The wife looked at my bags of cans and said do something with those or get rid of em so I have her to thank
I feel confident that my 4kg crucible and upgraded forge is big enough to cast one at a time
seeing that this has been done by others with Casting these side covers I feel confident in making em
next up who knows Im going to see how much aluminum I will need to making finned chain cover and finned clutch covers

I will update on the results when this lovely rain decides to disperse

Cast in sand or pressure cast?

Well the weather is sh1t today, cold, windy and wet, but I decided to attempt an "Easter Resurrection" (thanks Dave) of my bikes over at the self storage place. For reasons I really can't explain, I've been ignoring them for over a year now, so my plan today was to get the Triumph Rocket III and Honda VFR750 running, and maybe take them for a ride.

I've been filling their tanks right up to prevent rusting, so I took a 20 litre fuel can with me to dump their fuel into, and 2 x 1 gallon fuel cans with fresh fuel in them, along with my little lithium battery jump start box. The first thing I did was empty the VFR's tank, then dumped it into my car, assuming that my car would run OK on a 60/40 mix of good fuel and dead fuel.

Easter Saturday 2020 by Terry Prendergast, on Flickr

I managed to fill the car with just what was in the VFR, so I dumped the Triumph's fuel into the 20 litre container and brought it home to use as degreaser, or weed killer, or whatever. I dumped a gallon of fresh fuel into the VFR's tank, connected my jump starter pack which is a pain in the arse, because if you don't get the clips onto the battery's terminals perfectly, it won't transmit any power, which took lots of fcuking around.

My biggest concern was to get the VFR running, because everything I've read about them mentions what a pain in the arse they are to clean the carbs. The old Motobatt battery was in the bike when I bought it 4 years ago, so I was surprised that it held a charge right up to last time I rode it, but not today, it was dead. Once I got the jump battery's clips perfect the dash lit up on the honda, and after a bit of cranking, it fired up, on one, then two, then three, and finally four cylinders, and blew heaps of smoke, due to the crappy fuel that was in the carbs. 50% there.

The Triumph was a different story. Once again, the battery was completely flat, but the lithium charger didn't like it at all, and wouldn't transfer power. Poop. Oh well, I remembered  that I have a new battery in my garage that I bought for it three years ago, that hasn't had acid in it yet, so I'll acid it up, and put it on the charger, and (hopefully, depending on weather) next weekend I'll take it over and get the huge beast fired up.

OK, so the Honda was running, it was pissing down rain, but I found a full rainsuit in the rear case of my Yamaha FJR1300 that I'd forgotten I owned, so I put it on, put my jacket on, helmet, gloves etc, and jumped on the little VFR.

Easter Saturday 2020 1 by Terry Prendergast, on Flickr

I knew that things weren't going as well as they should when the electronic speedo refused to work at all, and the tach was reading 3K RPM when it was probably closer to 6. I did think about switching it off and back on again in the hope that it would reset, and even though I had the lithium charger thingy in the pocket of my jacket, I wasn't keen to switch it off again, just in case it wouldn't start again.

I have RACV (auto club) unlimited recovery insurance cover, but at the moment with the CV thing, I'm pretty sure the tow truck driver wouldn't let me sit in the cab with him and get a ride home, so I was a tad nervous about doing a big ride, when it was only working on power from the alternator, and the ignition was fighting the headlights (which can't be turned off on this bike) for power. It idled fine, but as soon as I gave it some throttle, the extra fuel would overwhelm the weak spark, and it'd miss and fart. I rode about 40 miles anyway, just to get the fresh fuel thru.   

Anyway, no biggie, I'll buy it a new battery for the VFR as well, and hopefully next weekend, take it for a better (longer) ride. ;D
 
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

My 750 hasn't run for the last few years, (due to my laziness) and not knowing wtf I'm doing.

Checked the points gap, and was like a mile gap. Set them right, now fires, but popping from the exhaust......wife and I both on lock down, and my firing her up is limited, but it does run a little better, whne I do get a chance to key her up.

If you've got a sh1tty old exhaust with a few holes in them, or poorly fitting mufflers, then that's probably your "popping" problem. I was (pleasantly) surprised when I ditched the 4 into 2 system (complete with poorly fitting mufflers) and replaced it with a new Delkevic 4 into 1, suddenly it ran much smoother, with no  popping.

I'd been wondering if the 30+ year old electronic ignition was slowly sh1tting itself, and I'd already done a carb swap, which it needed anyway as one carb body was cracked from some blockhead whacking it, probably when it had a leaky fuel valve, but it was still popping and farting, until I did the pipe swap. Suddenly it ran like a new bike!

That is, until the gearbox locked up 20 miles later, and it tried to spit me down the road. This was my skid mark, sadly when your gearbox locks up, pulling the clutch in doesn't do diddly......... ;D

Don't fall off mate, there'd be nothing worse than going in to hospital with a bad road rash, and coming home with Corona Virus! ;D

That's dead (no pun intended.......) right Per, as much as I love riding really, really fast, I'm gonna tone down my canyon carving until this terrible virus has completely disappeared. I don't even want to go visit my clinic, luckily I found some prescriptions for the drugs I take daily that I'd forgotten about, so I'm good for another month or so.

As long as people have behaved themselves over Easter, the number of cases here will continue to drop to eventually, nothing, and it'll be safe for injury prone clods like me to ride totally irresponsibly again! ;D

Twas only for a brief moment - hadn't had the bike on the interstate much since I finished it, and wanted to get a feel for if I had the gearing right. I think my digital tach is inaccurate over 5-6k so its hard for me to confirm my speeds match the gearing chart. Just wanted to see if it was capable of it - not planning on doing it regularly.

Rode her ~150 miles yesterday, had a great time.

and the first thing I did was take this backrest/luggage rack thing off to sell.

Yep, probably gonna invest in a set of those pipes for the 750.

These are some #$%*ty pipes I have on here now.......looks like a Kerker wannabes 4-1.

Had str8 4-2 on it b4, screamed like a stuck pig, but would not idle.. Been following your builds, wish I could do some of the crap you do.........but, I'm lazy as crap.

I do have a little CB100 I finally got going, and sum beech, playing around in the back yard, of course drinking like a fish........think I broke a rib laying down......so sitting here sore as f**k, and can't breath......but. I'm trying to stay away from the hospitals and docs..

Been laid off last 2 weeks, spose to go back to work next week.

Back to the 750, did notice one of the header pipes has a leak, and where the muffler attaches to the header pipes has a leak also.

I do have those pipes on my 350F, but haven't been able to get it running to see how they perform.

Too bad it isn't the correct rack for an F or I would definitely be interested.

 It looks correct Danny as I can see that it is made to swivel out of the way to clear the tailpiece. Note the wing nuts on it. I have one somewhere around for a F1 I took off if I can find all the pieces.

You're right. That is just a different style than the one that came on the F2 I bought my friend, but it would still allow the seat to open.

That one MAY allow the seat to swivel open without moving the actual backrest. On mine you have to first swivel the backrest then open the seat.

I just took a closer look at it. It swivels after loosening the two lower wings nuts. Here's the underside:



It's made by a company called Amco FWIW.

70 PSI at idle. It has to be the pressure switch that's gone bad.
