I installed the #90 main jets, removed the stock #38 pilots ,installed the #40 pilots, installed the new needles with the e-clip @ 3rd position, no shim below the clip, but three above the clip.The instructions in the kit suggested the three shims above the e-clip.
Went for a test run, the bike pulled strong to rev limit with full throttle through 3rd and 4th gear.
At part throttle acceleration there was a sag/ stumble around 5000 rpm through third and fourth.
I made four pulls with consistent results. My test ride is short because the road I use is too short for 5th and 6th gear testing.
I think either the stock needles will go back in and or the 38 pilots will go back in with the new needles to lean out the midrange.
When I achieve a decent power curve I will find a longer testing stage.
I am pleased with the results from the smaller main jets.
I did check the #90 orifice size and a #66 drill passed easily, a #65 would not.
The 112 jets I removed were drill size #57 before I drilled them to#56, and would drown the spark @ full throttle before and worse after drilling.
I'm learning.
