Back Firing Issue HELPP

[Cleandc5]

Ok the bike starts fine in one kick. i have no problem with this. now when i turn the bike on and try to rev it. it sounds like air is being released and instead of reving up it shuts it off.

So when i get the bike to run it starts running and in every geard its like it has a limit. were it just doesnt want to push any more so it starts backfiring loud. were you can see a flame come out the exhaust.

I think its the spark plug. because it sounds like air is comming out that hole. but i could be wrong. and the spark plug has a little bent tip.

PLEASE HELP

maybe start with changing your spark plug?

then check your valve setting, and check for air leaks after your carbie.

yep valve clearance, new spark plug and check your head stud nuts are tight..

and seriously do you really think people are going to reply to you at 2 or 3 in the morning...
