Title: Waaaaaaaaaaabrrrrrggghhghhhhhghh
Post by: laserred97gt on June 16, 2008, 07:06:44 PM
My bike is pretty much stock, stock air filter,  (for now), and stock exhaust (for now).

When I rebuilt my carbs on the bench, I set the mixture screws to 3 turns out (125 Mains, 40 Pilots, 1 washer, 3turns out).  After running the bike around the block the first time, it seemed like it was loading up and would die if I tried to let it idle.  Riding around the block the first time didn't charge the battery enough to keep the bike running and the spark was getting blown out.   

Saturday, I restarted the bike using my car to jumpstart it.  Good to go!  I started riding around and noticed some places, where it seemed that the bike was bogging.  So, I turned the mixture screws in 1/2 turn to 2.5 out. 

I rode it to work today, and head a few chances to open her up, and I noticed that it starts pulling really hard, and then falls flat on it's face at 8500 RPM.  The tack shows redline at 11,500, so not sure what gives,,   :mad:

I measured the float height, and it is about 3-4mm below the bowl gasket.  I will be adjusting this over the weekend, as I have a lunchbox coming, and will be installing that as well as a few orings that I didn't replace the last time I had the carbs apart.  Also, the petcock was on ON, not PRI.

Should I keep playing with the mixture screws, or do you guys think that my highend bog has more to do with float height? 

Thanks again everyone!

High end is main jet. Just under high end is needle (1/2 to 3/4 throttle is needle, 3/4 and up is main) and K&N is comming, so what filter are you running ... stock ... OK is it clean ?
Then floats 3-4mm, yea you're over 2 jets lean there. 2mm is 1 jet size approximately.
Cool.

I think I should just wait til I get the K&N.  Then I'll fiddle with it.

Would you guys recommend putting in the Kat rear shock before or at the same time I upgrade the front?

If I just install the Kat rear beforehand, will it make it unbalanced (too stiff in the rear)?  I've never messed with motorcycle suspension before.
