The stock 43 rear sprocket on the Jap model doesn't give me the extra push I need when coming out of the turns in the local track, specially going up the hill. The track is small and max speed is about 70 miles.
I tried to install a 47 rear sprocket but the chain is too short, just a couple mm
I had never considered adding a link to a stock chain before because the chain becomes weak, and it won't last... however, I don't think I'll have an issue with the stock 250's DID VP2 chain if I add a DID VX2 rivet link
What do you guys think?
