Hey, my friend has an 02 raptor with a Full Alba Race Pipe, Jetted, K&N w/ outerwear, Durablue +4 Axle, Flipped front tires, Renthal Bars, and holeshots..
Sometimes, when he goes to start it, it just sits there and makes a like buzzing noise and sometimes catches like its gonna start, but it won't....but sometimes it will start...and if it does do the buzzing noise...we have to bump start it...

I have heard the one-way bearings in the starter going bad on 02 raptors...is this the problem? Or is it something else?

Thanks Guys,
Warrior68Man

 

Sounds to me like you hit the nail on the head... the 1 ways are known to go bad... If he has the extended 3 yr warranty it will be covered. Mine was

 

Ahh.....he bought it off of some guy...and I don't think he had a warrenty...hmm...how much would it be to replace if it's bad?

 

It was a 400.00 job by Yamaha. Dont remember what the parts cost

 

It might be the starter relay or a bad connection.

 

You probaly need to search L&A Designs One Way. They make the best aftermarket fix for this problem.

www.raptortranny.com can help with the install.

 

you also may want to check the positive terminal on the battery... they have a tendency to vibrate loose which may cause what ur describing.

 

make sure both batery cables are both on there good, when i lost my bater screw/nut i just used a wire and sumtimes it would just buzz and not start, i doubt its the case here though.
