So I have searched and cannot find any specific thread about worn slides, I have heard other mention it, but am curious if my symptoms fit with this problem, I also would like to know if anyone has a way to check slides to make sure they are operating right.

Heres my problem, first of all it is progressivly getting worse, earlier this summer I noticed a very slight lean outish type stumble at 3500 to 4000 rpm. Its not noticable past there. I didn't change anything on my bike, it was stock carb parts. I took it to the shop they fubared it, and installed a dynojet kit fubared that, long story short I fixed all of their mistakes but am back to the original problem I just mentioned although now it is getting worse, much more noticable also from 2500 to 4000, its the same problem but with the dynojet needles and the original stock jets. I have 44k miles the slides are original and show wear, when I move them by hand the seem to operated ok, although on my friend's hawk his slide much better, his bike has 10k miles. Before I throw down $90 on each slide how can I confirm if this is really the problem. Also I would like to stear this thread away from jetting concerns and try to answer things related more to wear. I don't see how a problem would exist between the old jetting and the new and be exactly the same unless a shared part is worn out i.e slides, or my main jets since I am still using the original ones. I have tried alot of different jet setting and it changes the way it runs but does not elimanate the problem. Thanks all happy riding.

 

If your slides rattle in the bores, then they MIGHT be worn. In 100K miles on airhead BMWs with their vacuum slide Bings, I never found slides that were worn to the point of needing replacement. Slide needles that had worn from contract with the jets, leaking diaphrams, cracked and leaking carb boots and other ills accrued with age. But not worn out slides.

I suggest going the free, then cheap, then more expensive route.

Search for a vacuum leak.
Is the petcock vacuum line installed correctly and not kinked?
Balance the carbs to one another.
Make sure that the ignition timing is advancing when the throttle is rolled on. Are you getting a good signal from the throttle position sensor?

I also doubt that its a jetting issue and I'll bet when the gremlin is exorcised it won't be because of money spent on parts.

Give us an update on progress.

 

I have tried all of those things, even replaced the intake boots for added assurance none of those things fixed the problem, some of them did make it run better, but did nothing to aleave the original problem. I read on post about worn emulsion tubes, but was left very confused some people saying it was replacable and some saying it wasn't I am going to dig deep into the carbs later its gotta be a worn out part.
