now I know that there are so many jetting guides out there on this subject all ready and I have checked them all and still have same results. so the problem is that last summer I rebuilt my blaster with a vitos 240 kit it was all ready starting to get cooled off out side I had broken the motor in to specs in 4 different heat cycles. I replaced the main jet with the one supplied it is a 340 main jet and with the supplied pilot jet and put the new needle in the bike set on the middle setting my air screw was about 1 and 3/4 turn out to were it ran the best then.
the mods to the motor are the vitos 240 kit a moose 3/4 inch reed spacer v force 4 reed cage and a uni air filter on stock carb the pipe is a rdz left hand pipe
I have already ran the bike in the local sand drags it runs 6.551 is my fastest time in 300 feet at 46 mph the bike has run great on that day it was about 75 degrees out but now that it has made its way in to the 90s the bike has no power it acts like it is running rich it spits and sputters at high rpms in 1st gear threw 3 but then it seems to clear up a little in higher gears but still isn't all there.
I have tried every setting I could think of as far as main jet and air screw and the needle the bike gets extremely hot and leaves wet plugs but it starts really easy one kick it is ready to run I also did a compression check it is caring around 140 psi so all of that is ok the reeds are also closing
any help or advice on what I should try next would be a big help thank you
