Title: Thinking time.
Post by: BooG on May 21, 2010, 01:03:33 PM

I've been riding a K75 around recently, and I like it, but the R65 has a lot of class that you just can't match.
So, my cylinders fire with a bit of carb cleaner in them, but then cut out again. So there is a fuel issue thru the carbs somewhere. The plan? Buy some 32mm Bings off ebay to test with, and if I get a result ,keep em. R65 hasn't run since November!!

Just be aware that there are a lot of different Bing carbs in the 64/32 series .

There's a set of numbers stamped into the vertical flange at the front of the carb, should be something like : 64/32/325 .

Try to get a match if you can .

Any chance of a shop in your area that may have Bing carb repair knowledge ?

Hey just clean the ones you have.  They are not that complicated!

Have cleaned them, re-built them and they still are problematic I think. The coils deliver a good spark. Compression seems ok....Maybe a good quality ultra sonic clean?........ :-?

Given all you've been through I think that's not a bad plan.  
Carbs are saleable items so you can always sell a set once the problem is resolved.

Pity there is no one with an airhead nearby that could lend you a set just to get that engine started.

I'm at a loss of where to go from here, as I remember, your problem came on suddenly after the bike got rained on heavily while you were at work .

I know my bike will start at least and run poorly, if one carb isn't working .

I just can't figure out why both carbs would be at fault !!!!

I hope you can actually find out what the problem is .

Did you check the jet in the bottom corner of the float bowl.  Many people clean the carb bodies but miss this important jet.  If its clogged....

Good luck!

Yeah..even the jet in the bottom corners!! Replaced every seal etc!!
Maybe its not the carbs....however, that's a great offer Lou, and if you had the time and energy, I would be more than willing to post em north!! Got a baby due Thurs, so won't be up to much fettling for a week(s) or 18 years!!! ;D
