Hello, today i removed the head of my engine. The head have a lot of bites, dents and material removed around the spark plug area. The piston was perfect, only had traces of material around spark plug and exhaust port area. What do you think about? Preignition? Wrong polarity?

i mean this in no disrespect to e2s because it is home to me but i found a new fourm it seems good so far theres not many people yet so lets check it out!

My yamaha banshee wont kick down at all! I tried everything that I could think of. it feels like its stuck

I Bet you never seen this...

A friend of mine was going to race at Montreal's stadium (in front of 50,000 spectator) at the Monster Spectacular event, and just as he was driving to montreal (900+km) massive rain chopped off the road/bridge.





The thing here is that there's only ONE road. So he was missing the biggest event of his live with month/years of preps because of stupid rain. The Smart guy, who has lots of relations, good relations, shift PLAN-B at last minute.







He were there on time (without tools and backup parts, well...without his trailer) but at least succeed to race. Everything went A1.





And here's some bad ass engines (as a bonus) that was racing against him.
Don't ask me details on'em, I just don't know, except that the raptor above (at right of my friend's banshee) has a CBR929 motor. The 250r (bottom pic) is a Articcat F7 motor. Enjoy.

Think anyone will notice this handicap, seller prob bought it thinkin it was a 2 stroke. :Laugh8:
