[QUOTE="mandark1967, post: 1184385, member: 76062"] Smoking is not necessarily an indication that you need a top end rebuild. What color is the smoke? Is it blueish? That's normal if you have a 2stroke. If so... 1 Is your jetting correct? 2 Is your air filter clean? 3 Is your float level set correctly? Before you go tearing down your motorcycle engine, it's best to correct any jetting issues, clean your filter and adjust your float level. If the smoke is a different color, then you "may" need to rebuilt your top end. "If" you need a top end, you'll need the following (at a minimum) [B][U]Service Manual for your particular bike[/U][/B] Top-end gasket kit Piston Ring(s) Wristpin Wristpin circlips Wristpin bearings Radiator coolant (50/50 with distilled water in general) Circlip pliers Ring Compressor Moly Grease (if applicable) Small File (may be needed to file ring edges, if applicable) New Spark Plug If you do a top end without making sure your jetting is okay, you may very well be doing another top end 1 hour after your first one...
