[AIRMOBILE101]

Have you tried to clip the carb needle up one notch?

I agree that is how it sounds(like its not coming in high enough)..I have already installed the 3little red springs in the clutch..


I did try moving the clip on the needle(up and down) and it was much worse either way..
I have ordered some jets so we will see what effect they have..

What is the engagment of the red springs? I would personally go one set higher and I truely believe that would take care of your problems. With the work that you have done and the pipe you have created a more difinitive power band and you need to get close to that on engagment. You may even have to sit on the tank a little to keep down the front.

I talked with a guy at hetricks again..He said the torsion spring was a 1500 and the three red engagement springs were 2000 rpms and supposedly the stiffest you can get...He said the clutch shoes on the etons were heavy and that I was probably not getting a high enough stall speed even with the red springs...He felt a set of light wieght shoes would fix the problem so I ordered a set...Hopefully that will do it...

I am not saying they are wrong but it really doesn't sound like 2ooo, let us know what happens. This will be good info for a bunch of us.

Ok so I got the new light wieght clutch from Hetricks installed today..Bottom end is improved but it almost seems like its shifting up too quick now? Bottom video is with the new lighter clutch..
