pilot's good.

so I bumped the needle up using the c-clip instead of the spacer mod, this improved midrange throttle response and did well all the way up till the 70ish range where it seems to bog down on the last 1/4" to WOT
1st mistake, don't adjust the needle till the main jet is right. return it to the original position.
Quote:there is a spot just before WOT that actually acels better and hold speed better than WOT so I'm not sure what was going on.
this is a clear indication you need a bigger main.
Quote:Bumped up to 152.5 earlier today and tried the highway and same response at WOT just kind've meh...
return the needle to the original position and try WOT again. back off a smidge if it gets better than you need a bigger main. (thanks JOG for pointing that out)
set the main 1st then the needle.
what you're doing is pulling the needle completely out of the jet causing it to flood.
