bike wont get on powerband

[sangheraent]

alright well my bike was recently recoverd after being stolen and I cant seem to figure out one last problem. My bike wont powerband. It runs perfectly at idle and i can rev it up and its perfect jetting is good as well. and it just wont powerband no matter what i do to it. Im starting to think its a stator but whatelse could be the problem?

I would double check your jetting. If it wont get into powerband you may need to change your main jets...

thats what i thought was the problem too. but i opened up the carb and i got 168 mains and 50 pilots on my 30mm carbs. thats what I was running before when it ran perfectly fine.

 

The stator also checks out perfectly on the multimeter.

 

I also thought bad gas was the problem i changed the gas and still nothing. compression is 160. the plugs could be fouled but usually when i foul a plug it doesnt act like this.

 

could it be exhaust leak? the bike seems louder then it was before. i checked the packing and it was still new. so i dont know

check the gap on the pickup coil

do flywheels go bad? mine had a sand like crud in it from the old stator getting dirt in it.

I have had a flywheel go bad once and i chased my tale for a little,to me it sounds like a coil issue try swapping with a known runner

[sangheraent]

well I swapped out the coil and its slightly better but that may have been in my head. It feels like theres a massive airleak i donno why it feels like that but it just does. the bike is super loud almost as loud as when I ran it without silencers. but i checked the packing and its all in there still. i also checked the joints between the pipes and they seem ok too. I didnt see any smoke coming from anywhere besides the silencers in the back. im really thinking that it is electrical however the sound of the bike is just too damn loud im stumped. Im going to try a diffrent flywheel tomorrow.

you did all that without checking the plugs first?

Is it possible the theives rode it to death ? Maybe do a comp test . Plug caps?

X2 do a compression test

[Fullthrottle02]

Pretty sure i read in one of the posts above compression was 160. Sure 168 mains aren't way too big. What mods to you have?
