First off, my 426 since I have it jetted correctly starts first or second kick everytime cold or hot... I recently went to change out my Magura hydo line for a ASV lever/cable assembly...had to take off the tank to feed the Magura through and the tank sat off the bike for about a week before I could install the lever and cable. Once I got it all back together...the bike started like usual, and then died as soon as I touched the throttle...then it wouldn't start. I went through and checked everything... -took off filter in fuel line -valves (exhaust was tight but still in specs) -inspected and cleaned jets -tried with different fuel screw settings -inspected spark plug...good color and had spark When I put it all back together it still wouldn't start...so I threw in a new spark plug and *poof* started first kick! This is the 2nd spark plug in 6 months since I have owned it...is that normal, or are these thing that delicate?
