hey guys!
id just like to say that i hope im 1 of the rare few having success with this engine, cos it was on fire at my last race meet, the only thing that managed to pass it was a really high end nova.
but i do hav slight worries. wen i rebuild it after each meet, this time i noticed scratching on the backplate from the base of the conrod. should i be worried? or is this due to me not properly fitting the crank all the way back
any suggestions
thanks

but jeez thats a scary thought, gotta change my rod and the engine is 2 runs old(excluding run in), if this continues ill go broke changing rods faster than tyres
Well, after your first post I really was thinking your engine was already a bit older, but you say it is 2 meetings old?
But 2 meeting doesn't say anything, how much fuel went through the engine?
Tiny "rotation" scratches on the back plate is normal, and you will see them on every engine.
In general, it is not uncommon to change the conrod right after break-in...
The advise (I believe) for Ninja engines is to change the conrod after 5 liters after break-in and from then each 7.5 liters....
