So I put the 110 main jets in today. Threw everything back together and went for a test ride.

The bike feels much, much, MUCH better. And a lot of the previous observations i made make sense. Like when i went from the 115 to the 118 i thought the mid range and mid throttle felt a little better. Which makes sense because it was lean.

So yes, 5 washers, ~ .12" raised from stock height and the mid throttle and mid range feels much improved. With the 110's the WOT is significantly improved and pulls nicely.

Not sure if i should try the 108's or not. I don't have any so would have to order them specifically.

I still need to mess with idle mixture screws and sync the carbs

but all in all the bike is running good again and is fun to ride.

So road to work today and the bike still feels good. Definitely rich at 1/8th throttle so i might go back to the #38 pilot and hope that it does not affect my 1/4-1/2 throttle to much as i think it is pretty spot on. As far as the main jet is concerned i am thinking i might be a hair rich at WOT between 9k and 11k rpms. The bike pulls pretty good especially at 10.5-12k but i thought i noticed a slight hesitation today when i cracked the throttle a few times. However i feel like i am starting to split some hairs here as i definitely think the bike runs very lean from 12k-14k not that i run that range very often but leaning out the main jets any more and i am thinking i might have to be careful with sustained throttle in the 12.5-13.5k range so top speed runs might be a bit risky. But i could potentially get more usable power in the 9-12.5k range with the 108 main jet which i think would be great.

I kind of wish there was another circuit to tune for these bikes to get more power out of the high revs. I guess the bike isn't made to be run past redline in all but I know when i had the 118 main jets in the engine would come back to life after 11.5k rpms and pull hard past redline. I can definitely see why using a larger main jet for a top speed build could be beneficial.

I need to order some kehlin 108's, I might buy some random minkuni needles that look like they will fit for fun as well. i might get around to putting the jets in not this coming weekend but the next. And then after i try the 108's like or dislike maybe end up going back to the 110's. i need to get the carbs synced and then get this thing to a dyno see where things are at, adjust if i have to and maybe do some fine tuning of with the ignition timing.

So far so good though.
