Tom_H123 Posted March 13, 2019 Report Share Posted March 13, 2019 Had a ride the other day and the exhaust went pop/bang and then cut out and wouldn’t start again... every few kicks it makes a pop/bang, I have checked the spark and it’s fine.... also checked to see if flywheel was spinning freely and it wasn’t... will I need to get the flywheel off to check the woodruff key? Also spoke to my local trials bike shop and they said it could possibly be the CDI that has given up... how could I test to see if the CDI is the problem? Any other ideas?

thall1 Posted March 13, 2019 Report Share Posted March 13, 2019 Its flywheel off to check the key...don't know how to check the Cdi ... Can you borrow one from another bike to try? Quote Link to comment Share on other sites More sharing options...
2smoke Posted March 13, 2019 Report Share Posted March 13, 2019 Hi, if your flywheel isnt spinning with the engine then that would suggest a sheared woodruff key. Quote Link to comment Share on other sites More sharing options...
tshock250 Posted March 14, 2019 Report Share Posted March 14, 2019 Or it is spinning but its shifted to the point where the timing is screwed. Quote Link to comment Share on other sites More sharing options...

I will get the flywheel off as soon as I can, and no I haven’t got a CDI that I can borrow off another bike sadly Quote Link to comment Share on other sites More sharing options...
