My stock one is fine but noisy and LR recommend a quieter #25 chain but doesnt sell them himself.
Id like to reduce the noise first off, and maybe change sprockets on the left side of the motor as well
thanks
The chain, stage 1 reduction, of the stock GNG uses a #219 chain. The noise issue is caused by the small driver sprocket that is too small for the size chain. Not enough teeth are engaged. What many of us have done, is replace the #219 primary reduction with #25 sprockets and chains. Overall delivers a much quieter setup. But you need more than just the chain.
Here are some url's to the #25 sprockets and chains that I used to replace the noisy #219 primary reduction.
If you have the chain version of the GNG, this large sprocket is a direct bolt on.

13T driver sprocket http://www.electricscooterparts.com/sprockets25chain.html
The motor shaft has a 8mm flat with a 10mm diameter. However, it only sticks out 2 inches, so you cannot use those wider driver sprockets, have to use the smaller thinner ones and I think they come in 13T maximum size.
I hope that helps.

Thanks for the links!
Would this 13T be the same as the 13T sprocket in the above link at electricscooterparts.com?

If so then I could order all parts from tncscooter to save on international shipping
Don't know, it doesn't give the specific dimensions. It looks like it is at a glance.....
