ok i was warming my bike up letting it idle for about 10 mins every thing seemed fine but when i hit the throttle to clear it out i seen the right silencer blow smoke rings like o o o o out the pipe and on the left side it backfires a lil bit a popping sound

 

what i wanna no is could i have bad reeds or was my bike overheating

or do i need to jet it right before i destroy my topend or did i already f*** it up

and it takes about 5 kicks with choke all the way out to start after sitting for weeks is that normal?

jetting

200 m

25 p

mods

fmf pipes

pro flow filter with no lid

compression

115-120 on both sides

What is your elevation and air temp?

 

200 Main sounds REALLY low for the carbs, especially with pipes and filter. You should probably be at least around a 260+ on the main (depending on elevation and temp).

 

And as far as the pilot goes, you might be lean on that as well. How many turns is your air screw up when you see best performance out of the carb, off idle (while the bike is under load)? And where do you have the needle clip set?

 

Oh, and are the carbs in sink, choke crossover tube in place?

FMF pipes like a bigger pilot. Use a 27.5 for the pilot, and set both air mixture screws at 1.5 turns out, and it will start a helluva lot easier. It's starting hard, because it's lean.

well i thought it was really low and temp is about 80 every day now and im at sea level

and im 2 turns out on airscrew ,needle stock and the best peformance is 1-4 gears and 5 and 6 suck it

doesent pull it sputters it feel like going from power band then i hit 5 and then it feels like a thumper

and as far as carbs being in sync there ok but not perfected

At your elevation I would go 270 mains, 27.5 pilot, needle on middle clip and airscrews 1.5 out for your mods. That should put you real close, then do a plug chop to verify.
