Hi all. A friend of mine has a 1100 DI that he recently purchased. Seems to run alright (when it's going) but tends to eat spark plugs like its going out of fashion. Will start and run fine on a new set of plugs for about 2 outings and then on start up will miss fire, stall and run like a BOS (bag of s...) until it warms up. From then on it goes great until it is cold again then the problems repeat themselves.

It takes about 15 minutes of starting, stalling, restarting, stalling until it keeps running then once it is hot it is unstoppable.

The question I have is are the plugs causing the issue and if so why does it disappear once the ski is warmed up?
