They are different motors PE has a shorter stroke .
OK thanks. Well that answers one question I guess!
I suppose I am trying to establish a base to work from - how does the PE compare to RM in low to mid range? Without having another to compare to, I need to know how much power a PE
should have. Does anyone have one of each who can say for sure how they compare?
I remember having my first ride on the PE (many moons ago) and thinking "this things got some grunt!" - and i was coming off 84 KATO 500's, the ultimate tractor motor!
Then after 4 years (and the port job) I had my next ride - bit hard to compare the feelings 4 years apart! So i'm not sure if i lost mid range power in the process??
I guess i can sum the bikes performance up by saying that when i exit an off camber grass track corner, i either have to dial on the throttle and wait for the power to kick in (frustrating) or clutch it like a 250 and risk getting out of shape. I want to steer with throttle but cant! I would have thought this motor should be capable of that.
As far as the motor goes - it is in new condition, i've explored all jetting configurations (runs clean) and the timing is already a touch advanced (so in theory should have more grunt?) Going richer on pilot and/or needle only worsens things.
I'm thinking its a port timing / pipe thing?
