my favoritive enduro bike It 490 and 82 465 only thing you have to got good leg for kicing hard

[@KeepitBigBore]

Really? A lot of people have said the “IT’s” we’re the best enduro bikes ever made! Have you got one now? I read somewhere that the 465 was the better engine?! I could modify this cylinder to accept a decompression valve if it’s too much to kick. I don’t want to crack the case from kicking!!!

ive got an 84-IT 490....no spark....what could be the causes of that!!?

[@KeepitBigBore]

A few places to start id say. But start with the simplest thing first, the kill switch, the ignition coil, the wires and lastly the stator. 9 out of 10 times for me anyways it’s a coil, wire short or just a bad connection. Oh and check with another plug if you haven’t done so already. Make sure the ignition coil has a nice connection to the frame and the same for the engine.
