Thanks for the replies.
So if I swapped in 23cc domes and everything else was the same(squish and profile), it would require bigger jets and more fuel, correct statement?
The reason I ask is because it seems a little flat in the midrange until it gets on the pipe. Wondering if I would have to go down a cc or two to get more midrange.
Had been playing with the needle positions, went 1 step leaner on the clip, then 1 step richer on the clip. Seemed to be lacking some "zing" 1 step richer, so wound up with the needle clip in the middle position. Then went down from 160 main to 158. Just think when going to WOT it should build r's a little faster on its way to getting on the pipe.
Compression test yielded me 135psi each side with 26cc domes and timing set to +4.
My pilot is a 50 and carbs have been synced using the sync tool that FAST sells several times. My slides are #6.
Another question:
My method for adjusting the pilots is as follows----I turn each screw out equally until the bike achieves its fastest idle speed. Then I count the turns and I am usually around 3 turns out on both pilots. This leeds me to believe that I am rich on pilots, but I really haven't noticed any real change in performance with the pilots 1.5 turns out or 3 turns out.
One thing I have noticed is that when I start it at home when engine is cold, starts usually 1st kick with only occasionally having to use the choke.
Idle is good and solid, although when motor is hot and after stopping for a few minutes out on the dunes, again starts first kick but idle seems considerably "lazier" and somewhat lower. My thoughts are it is loading up, but why doesn't it load up when its at home. I have let it get to operating temp at home and the idle is rock solid. Think I will just have to get a pair of 45's and 48's coming.
Any thoughts will be appreciated as always.
Thanks.
