hoppedupandcutdown Posted May 29, 2018 Report Share Posted May 29, 2018 Something build a nest in your exhaust pipes? Quote Link to comment Share on other sites More sharing options...
Beriro Posted May 29, 2018 Author Report Share Posted May 29, 2018 Dont think so but ill check bike was sitting in peices for 12 months before i got this motor Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted May 29, 2018 Report Share Posted May 29, 2018 Check that the pistons aren't in backwards while the pipes are off. Stock carbs, slides in the correct way? But my money is on a critter home in the pipes. Quote Link to comment Share on other sites More sharing options...
Beriro Posted May 29, 2018 Author Report Share Posted May 29, 2018 Iv checked the arrows threw the plug holes they are pointing the correct way and just checked pistons look to be the correct way. Ill run some compressed air threw the pipe and see ig theu are clear Quote Link to comment Share on other sites More sharing options...

Larry's Shee Posted May 29, 2018 Report Share Posted May 29, 2018 What's your total setup? Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted May 30, 2018 Report Share Posted May 30, 2018 Do a compression test to check rings. If reed valves are not sealing correct you can get some blow by but it’s not usually exhaust. Maybe someone doesn’t know how to size pistons and rings aren’t sealing 1 Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted June 3, 2018 Report Share Posted June 3, 2018 Set pick up gap on flywheel nubs. Clean coil ground. Un screw spark plug caps and trim wires off a CM. Fatter pilot jet if it's not a stock build. Verify pipes are clear. Make sure fuel is flowing through petcock. Quote Link to comment Share on other sites More sharing options...
