What year carbs? There are about 5 different banks of carbs for the cb750 (1969-70, 1971-73, 74-76K,75-76f and 1977-78). some are minor differences like throttle bell crank and cable actuation, others are completly different (ahem...77-78).quote:
I wanted to know if anyone knew the size of the o-rings that go on the "t's" that go inbetween the carbs on a cb750? I thought that I had read on the HondaChopper page years ago that you could use some that are available at Home Depot/Lowe's etc. and that they were green (natural gas rated?)

I happen to like the 75 carbs (BTW I hope I wasn't being too harsh in my last post), the 78 carbs are a pain in the arse. Next set of questions:quote:
Geeto67,
I forgot. Try not to beat me up too much.
I have a '78 bike, but I kept a set of carbs for my '75 and those are the one's I am going to rebuild. I have already bought the intake isolators for that model ($100 OUCH!). I think that i'm going to have to do something with the throttle cables, but i figured that was all easier than trying to rebuild the original carbs. The guy I got the bike from parked it in 1982 and didn't drain the bowls and the sliders were STUCK! I kept them just in case the swap turns tits up. That way I'll have something to fall back on.

the best part about honda is that you can order almost anything for carb rebuild individually (this is also the worst part about doing a carb rebuild when you need everything). For your rebuild I would go to honda and order the o-rings and float needles, and reuse all your other stock honda hard parts if they are still good. I would not bother with an aftermarket cab kit like K&L or Keyster as the only useable parts out of it only seem to be the rubber. The needles are usually manufactured to a wider tolerance than honda and it is hit or miss on whether they work.quote:
i was just kidding about beating me up. i've been on some forums where if you didn't do a good search before hand, or forgot ALL the pertenant (sp) info some folks really got on ya.
I don't know if the leak. they've been sitting around for 5yrs and since i was going to take them all the way apart for cleaning, i thought it would be best just to replace them. even at $1 a peice it would only be $8 to have new ones. I look at it like it's a small price to pay to keep from having to take them back off.
