I have a question about your carburetors.

Is there a throttle return spring located behind the small wheel that you hook up the throttle cables to?

I bought a used FCR39 carburetor off of the internet and my slide doesn't snap back when you let go of the throttle. I'm thinking that there is a spring missing.

Any help would be appreciated.

Thanks!

Next question. Does anybody have any idea where I could order that part from? Yamaha is no help. Since that part is not set-up as a replaceable part, all they can do is sell me the whole carberator.

I have put a couple of emails out to Keihin, but haven't got any response back.

Go to bikebandit.com input your bike's year and model and look in the oem section and you will see the exploded view of the carb with all the separate parts. I have ordered from them 3 times in the last 3 months and have received great service and their prices are pretty good. :applause:
