Flywheel Weight causing low end BOG
Posted September 17, 2002 - 07:12 AM
Have WR timing, and jetting just about spot on.
PAJS 1/2 turn = 65
PS 2 turns
Before adding a 12oz flywheel weight I had snap wheelies in just about any gear at any speed.
Had good snap from closed throttle with no bog.
Now after adding a 12oz flywheel weight I have that closed throttle to snap open BOG. Sometimes it boggs then BAAAAROOM picks right up, and sometimes it bogs almost to a backfiring sound then dies.
As long as the throttle is open a little and then I snap it open it runs fine.
What should I try first clip position or APJ.

you're only slightly rich. THE HESDITATION ONLY HAPPENS WHEN YOU ARE SLIGHTLY RICH.
so take your PC right down and it'll then disappear.

Would delaying the squirt on the APJ fix the problem instead of changing PJ? I'm already down to about the smallest squirt I can get. I have a 99 so to delay the squirt I would have to bend the tab out.

don't change the ratio just to lean out the PC. go 38/60 and that should do it. you're just a little unlucky that's all.
also don't forget to adjust your PS to the best position to snap the throttle with.

I'll give it a try tomorrow and post results.

Then using the FS went from 1/2 to 2 1/2 turns out and got most of my snap from closed throttle back. The BOG is almost gone at 2 1/2 turns.
I guess my next test is to try just changing the PAS which is set at 65 to maybe 60 or 75.
Then I'll try the 38PJ and 60PAS.

38PJ, 60PAS and my snap is back very little BOG from closed throttle when snaping it open.
I think I just need some more riding to adjust the fuel screw and maybe slight adjustment to the APJ.
Good wheelies from just a little throttle and whack it open in first and second gear.
