my 04 raptor 660R is messed. i took it out of the shed today warmed it up put it in first and it had nothing... it would go like 3 mph and then it would just choke on its self and backfire... got no clue whats werong with it but i have checked the spark plug and cleaned that up a bit... put some drygas in the tank...it was warmed up plunty.. the airfiler and oil were recently changed and it ran fine after i changed it so if anyone has a clue wtf is going on tell Me please... thankyou.

 

is it running fine currently? sounds like the clutch plates were stuck and they freed themselves, how long was it sitting before you rode it?

 

If it idles fine but won't take the gas the e-brake switch may be malfunctioning causing the rev limiter to kick in.

 

1 ANSWER!! E BRAKE BLOCK OFF KIT!!!

 

well im going to take it to the shop tommorow but my friend said it might be a clogged jet and someone else i know said it might be the e brake...if its the e brake can i fix it at my house?

 

yea right now it idles ok... and will allow me to give it a bit of gas but if i give it to much it boggs down and chokes on it self... i havnt done it yet but im shure if i went full throttle on it it would shut off.

 

same thing that happened to mine im positive its a clogged jet. take of the carb clean it all out and clean out your filter and buy an inline filter . it will run fine after that promise.
EXACT same problem i had a week ago.
you have stuff in the bowl that is getting clogged in the jet.

 

i am positive you're wrong...

a clogged jet (most likely pilot since it is lowest in the chain) it would fix itself above that...

a parking brake issue wouldn't get better at all... and only allow the rider to go about 1/32 throttle when it is engaged before it wants to engage

 

yea my friend has an issue with his jets were they were clogged and it wouldnt run well but i just went opur side and i pulled what i think is the parking brake rev limiter thing and it runs great i dont know if its bad to do that but it runs like normal now so yea is that bad or not?

 

Everybody takes that POS parking brake off, just be sure to put a block-off plate on the brake.
