Not satisfied with stock gearing so going to play around with new gearing. Do these parts look right:

JT Sprockets JTF516.13
JT Sprockets JTR460.45
RK Racing Chain 520-SO-108

I hate having to buy a new chain but google said I needed a 108 link for the new setup (mixing in the stock 42t too).

 

Those should be the right #'s. I usually buy my chains in 110 or 120 link lengths and cut them to fit. They are usually cheaper and it allows me to play with altering wheelbase with chain length. The tool to press the chain pin isn't that expensive but it can be done with a grinder and a punch.

 

Good to know. Thanks.
