Jetting!!! Again and again and again!

<< < (22/120) > >>

kawdude:
Mo better.  I haven't had a chance to continue my jetting quest.  Right now I'm at a 170 with the clip in the middle.  I moved it there from the secound clip and noticed a response difference.  Less snap.  Not a lot but it was different.  I will drop it back to a 165 and see what happens.

mjscore:
My 94 came with  N82R as stock, is the N82M a leaner needle? According to the Kawaski web site it is not an option until later years. All I know is that no local Kawasaki dealer has one in stock so I will have to order it. Mine will only run with the clip in the first position and it surges on downhills. I have a 168 main with a 55 pilot and 2 turns out on the air screw.

kawdude:
I think the R is richer.  The surges are coming from to much gas getting into the idle circuit.  Adjusting the pilot screw may help.  I don't know what you altitude is but dropping to a 52 pilot could remove the surges.  On my 94 I had to replace the slide and lean out the pilot.

gowen:
Did replacing the slide help? I am thinking about that, just to see if it helps. I have a #6 slide, but the stock and what I have in it is a #7. But, no sign of being worn. Anyway, no reason just curious.

kawdude:
My slide had a ding in one of the corners so it did make a difference.  Wasn't a perfect fix but lowering the pilot jet and fiddling with the air screw has helped bunches.
