Resident carb guru gave me the jet sizes i needed and he was spot on. Can't remember the size. I'll check.
I was told the 28's can be made to flow more gas than a set of 29's.Don't know enough to comment.
Any way with the 1075 and Andrews 3X the old bike screams.
I installed a set of 34's night before last and didn't have a chance to ride as the rain has started again. I do know the idle has improved to the point i can back the idle down to practacly nothing.
I'll let you know how it works.
I need to know what tools were used to clean those head ports up with. They look great.

I always wondered about 28's and finally put some on a 1015cc motor. Easily noticeable diff in top end pull. I don't think it's enough though. I think bs34's are good for some real hp and these bikes jumped up in hp because they were used in place of the 26's and 28's. In other words "good carburetors". Sometimes when carb differences are noticed from one set to another it's just the fact that one set supply's more fuel to the engine. Id bet my engine would jump up 10hp if I put on 34's of the bs kind. I would like to know the diff in hp between the 29's and 34's. Don't matter how smooth they there only 29mm any way you look at it. The controlled opening of the bs's slides means high velocity all the time. To me that means faster acceleration. How'd the world get flat again anyway? We need a dyno test result of the 29's and the 34's to back me up here.OK, I have noticed no one even mentioned the 28's that came stock on the 80 ltd. If you are looking for a bargain basement deal and maybe later put some 29's what about the 28's they have to be better than the 26's and although not 29 smooth bores they could be had for as cheap as the a stock set of 26's. Wouldn't that give you a little jump? As I have said I only read about the hp from the manual and I never rode my bike with the 28's on but I would think that they have to be a bit better than the 26's.
Anyone?

I will not be running these carbs after i get my jets from Z1E. Those 34's just do the job for me.
I know about beating on crotch rockets. They seem very suprised.
I am selling on eBay to get me a smaller chain. The bike is geared too low and i am mostly riding 55-60. Roy
