Don..... checked my s/c horn today (see pics). Easy enough to flip the mounting tab over on a new one, BUT the wire then pokes out the wrong way. A new horn would have the wires sticking out the outside of the horn..... the original has them tucked in under the headstock. Mmmmmm??

A silly Q?, but what horns were gray plastic with a regular cover and a silver wire cover?

BenelliSEI · « **Reply #677 on:** September 09, 2021, 05:07:25 AM »

Don..... that’s the original horn from #1250. It’s really not grey, the phone takes weird photos under fluorescent lights. It will be black when clean. Th wire cover is grey.

I had a gray/silver one that I always thought could be early 750 but it appears to be cl450. That said, we know if Honda only had access to gray ones and needed to build a bike it would have went on. I've been telling the facebook cb750 experts there are exceptions.

I looked more closely at the wires and cover today. What you see in my poor photo is the light green wire, looking gray. The wire cover is faded, but definitely black.

The sandcast got a drink of avgas today and a ride to flush out some fuel

Terry in Australia · « **Reply #681 on:** October 12, 2021, 05:46:14 PM »

How’s it like the Avgas Don? My K0 with super high comp pistons loves 98 Ron fuel (and hates 91) so if I could get my hands on some Avgas I’d give it a crack?

I just got a gallon or less in it to top off the tank. My main reason for trying it is it doesn't spoil like pump gas. My buddy that works there said he has started 20 year sleeper airplanes and they fire right up.
The best starting and smoothest running cb750 I ever bought came from an airport. The manager kept it in his hanger, it never left the airport so got few miles, and fed it airplane gas. Also a friend that has Indian motorcycles from the 40's also mixes airplane gas with no alcohol pump gas 50/50 He rides his less then I ride mine and never has to clean a carb.
I just drained a mix of old pump and race gas out of my 40 chevy, there's 10 gallons to dispose of somehow. I can't even blend it and burn it because it has leaded race gas in the mix.

I got the old girl up to 90 with the 4-4 pipes and fuel mix around 15/85 or so, it's been 105mph with a Hooker 4-2 exhaust setup before I realized it had stabil in the fuel, it didn't turn them blue.
I think it wants a carb balance but above idle it's awesome.

I also gave the K0 836 a taste, it got closer to a 50/50 mix. It already had 91 octane no alky in it. I'll ride it as soon as weather allows, rain tomorrow. It's cammed and ported, I may get one last shot for the year to get it on the drag strip this weekend.

I recently visited my local Honda “power products” dealer and noted they are selling Honda Fuel in orange and blue, 4 litre containers. Two stroke pre mix, and 4 stroke. It costs a bit less than the stuff my STHIL chainsaw guy is selling (a tall boy beer can of their fuel is Cdn$19.99!). I’m going to get a jug of the 4-stroke stuff. Thinking I might load my remote fuel tank run all the bikes on this stuff, before winter storage? In theory, they should all just fire right up in the Spring?

?

Don R · « **Reply #685 on:** October 13, 2021, 12:48:07 PM »

Good idea, I've been using canned fuel in my Poulan chainsaw and it runs better every time I use it. I also began using seafoam and no alky gas in my push mower and it's the same, the more I use it the better it runs.
My Yamahopper pit bike appears to need a carb rebuild though. I still use the oil injector, I sucked it out with a turkey baster and replaced with Amzoil synthetic 2 stroke oil and add a dab to the gas. I added a bit of AV gas to it too and rode the stink out of it to get some in the carb before storage. It's smoking a bit more than usual lol.

I’ve run my small engines on engineered fuel for years. Ethanol just kills small engines. My small generator (Honda) gets ethanol free. My large generator, also Honda, gets propane, my two strokes get 50 Fuel.
My Ruckus didn’t like ethanol fuel but runs great on ethanol free. Of course the K3 and Z1 ( when it’s together) run on ethanol free.

RAFster122s · « **Reply #687 on:** October 13, 2021, 04:09:36 PM »

Here in AZ we do not get a choice, everything has ethanol and last time I looked PureGas wasn't available anywhere in the state.

Fortunately my modern bike tolerates the ethanol fuel. My CX500 does as well. Given my CB is waiting for me to start it's restore now I have most everything...I can't answer that one yet.

My club car golf cart despises alcohol, acts like it's vapor locked. My bikes burn alcohol fine, it just doesn't store as well, I'm paranoid about moisture in the wrinkle tanks. My gl1000 loves 87 octane and hates 91, I think Hondaman explained that with the slow burn causing burn back in the intakes.

Random practice pics. my KZ and F'n project.

Wow, finally get to see the kz! Looks pretty good. Has tons of potential anyway.

BenelliSEI · « **Reply #692 on:** October 15, 2021, 10:28:42 AM »

Don..... I refurbished a KZ1000 that a friend bought new. He started his own business, family, etc. and it sat for years, always warm and dry! It took a while, but what an awesome ride!! I was really impressed when I rode it. They are quick. Great project.

Don R · « **Reply #693 on:** October 15, 2021, 10:09:49 PM »

I had a kz900 ltd dealer bike for a Saturday. Why I didn't buy it I don't know. I had a Windjammer equipped cb750 K3 and we took trips on it. Probably $$ had a lot to do with it.
Everybody around here wanted the ltd, When I get the time machine I'll have a Sandcast new and a Z1.

The diecast has an 836 that I've been tuning a little it's rich in the mid range. Today I took the baffles out and took it for a test ride, the plugs went from black and sooty to brown and the ground strap is burned off back most of the way.
When I got home I considered dropping the needles a notch but remembered it got 2 gallons of LL110 av gas on top of what was in it. Sort of makes the test ride a moot point to a degree but I still think I'll drop the needles.

Terry in Australia · « **Reply #695 on:** October 30, 2021, 04:31:14 PM »

When I fitted those expensive, but pretty "Rebuilt by carb expert" K0 carbs it was running a tad lean, so I raised the needles, but still wasn't happy with them, and discovered that the "Expert" didn't install the slide top seals, the fcuking numbat, so they were sucking air through the carb tops. I guess it's easy to be considered an expert, when most of your customers are noobs.

Anyhoo, Jona, my mate in Israel, had sent me some carb rebuild kits he'd mistakenly bought for his K7 and lo and behold, they had the K0 specific seals. When I installed them, the engine ran so much smoother. It now runs a tad rich, but I haven't bothered to drop the needles as it goes like a raped ape (I've never seen a raped ape, so they must be pretty quick) and while it's running well, I'll leave it alone.

Don R · « **Reply #696 on:** October 30, 2021, 05:24:16 PM »

I've been in these carbs but can't say I actually remember seeing gaskets lol. Something to watch for. I need the top boots either way. .

Terry in Australia · « **Reply #697 on:** October 31, 2021, 02:17:45 AM »

Yep take a look Don, seriously, your bike will never run right without them. They're not plastic, like the K1-K6 seals, (although you can modify the K1-K6 seals to fit, if you've got a set of gasket punches) they're just a paper gasket, but the difference between the "before and "after" was enormous. Still boggles my mind that the idiot who "restored" the carbs didn't install them.

+1 to this! Years ago, when I picked up my fits cb750 K0, I immediately sent the carbs off to Mike Nixon. They came back beautifully restored, carefully, perfectly packaged. The slide/needle assemblies where all individually wrapped (on their individual cables), tied together. Instructions included, already “bench sync’ed”. Really nice work.

Years later, when I finally restored the bike, it fired instantly and ran well. HOWEVER, when I tried to vacuum sync., it drove me nuts. One or two matches, move across and everybody changed. The bike would run perfectly and then suddenly go off..... I took it to Cobble Beach, won a prize, and wrapped it up in the back of the shop (Winter set in).

Much later, on a shop “Clean Up” day, I emptied out the box Mike Nixon sent: instructions, my old throttle cables, cut zip ties, bubble wrap......... and a small package with 4 X top gaskets!! Runs much better now.

The Sandy has a rear brake squeal, that's got to go. I left the original shoes in it but may swap for a set of segmented EBC shoes. I cleaned it really well but it deserves a look to see if something is in there that shouldn't be.
