New to turbo Yamaha coming off a turbo pro. Bought a 2010 nitro with a 270 mcx looking over sled tonight and found a couple thing that need to be fixed. Track has a couple of tears just wondering what is the best track with no mods it is a 163. Also found exhaust leak right before the turbo pipe is cracked away from turbo flange. Just wondering everyones take on this.
