Try just swapping to K&N needles instead of the stock. You have the stock needles right. Just put in K&N ones and try it. That should be near perfect.
Cool.

OK, here's the deal.  I've got the K&N needles in along with the K&N plugs... all per the instructions that came with the jet kit.  I've also got 40 pilots, 135 mains, and the mixture screw 3.5 turns out.  This setup is coupled with the Uni pod filters and a stock pipe.  The bike runs incredibly well now... much better than it ever has before.  Starts right up, and pulls strong the whole way through the curve.  The only ill performance I'm still getting is up at 90+ in 6th (This is ~8000 rpms: I've also advanced the ignition ~5 degrees).  There's still some hesitation at that speed, so I'm going to try out some 137.5 mains.  If those don't help, then I'm pretty sure I'm just maxing the engine's power output.  If they solve the problem, well, better still!

Thanks all, I've never had it so good!   :thumb:

OK Plugs mean those white things to block off one of the slide holes right. OK K&N supplies a 134 as their largest jet. 8K should be fine on this bike, even one as worn out as my 89 dont run out of steam till 9K. Better motors should make 10K easy in 6th. So 137.5 may help, but K&N recomends lifting the needle some more if it doens't behave at 134 mains. You are real close but I think following K&N's advise may be easier and work out just fine. Their needle profile is very steep in the lower 1/4 inch so they may have this situation addressed in the design of it.
Cool.

Ahh... good idea.  I'll try the washer instead.  Either way, I'm pleased with the way it's running :).

With K&N you need to slide the clip down into a lower (as it sits in the carbs on the bike) groove. Washer technique is just a more crude way of accomplishing this on the stock needle.
Cool.

Even better!  I guess there are subtle benefits to the jet kit after all (still not worth $30, though).  If I'd trusted my instincts, I'd have followed your do-it-yourself advice from the get go.  I'll know better next time!

Thanks,
