Hi all,
I've built my new engine, dasa +10mm, 90mm pistons.
Domes size are 44cc and compression is really too high for recreationnal ski, around 220 psi. I use 98 octane fuel (but with this high compression, race gas must be better choice)
Engine actually run bad, good out of idle but bad mid range and I can't go to top, I'm afraid to break something
I've rode only 20mn and sparks are really dry, top of pistons are brown
Complete setup is :
pf pipe turn into wet pipe, 80 jet in the injector, no water in the waterbox (just a box ahahah)
MSD TL
Dual novitec 125L, 135H, 2.0 and 95g spring
Do you think I can change dome size to have something around 180-200 psi ? (46cc, 48cc ?)
What do you think about the carb setup ? (works very good on my dasa 872cc)
Pf pipe turn into wet pipe can cause problems ?
