Not sure if this is the correct forum... but
Upon normal take off, I have a ratchet-like drive from my 08 Nytro MTX. Not the normal smooth clutch engage/ start off. At first I thought the stock drivers were slipping until I got moving. However, it doesn't ratchet when I pour the cobbs to it. I might have the chain too tight? (adjusted finger tight, then out 1/4). The track has about an inch of slack to the sliders when off the ground. Where should I look first? Thanks
