Andre1150 Posted October 30, 2015 Share Posted October 30, 2015 and here's why it was backfiring when it was running.. a stuck exhaust valve. on the right valve you can see a hairline gap.. losing compression. Link to comment
dirtrider Posted October 30, 2015 Share Posted October 30, 2015 Morning FireKit What did your compression test show? The larger valves are the intake valves. Link to comment
kalali Posted October 30, 2015 Share Posted October 30, 2015 How many miles on the motor and how's the bike ridden; hiway, short rides, etc.? Link to comment
Andre1150 Posted October 31, 2015 Author Share Posted October 31, 2015 87,890 on the bike. it was an rtp to 60k, then 20k in 18 months highway. I didn't measure compression on this cylinder before teardown. Link to comment
