Yea I upped the octane last time I filled with 93 and used synthetic race oil 40:1 - between all the changes (Tires, Trans fluid type F) and tuning (pilot had to come out a bit 1 &1/4 turns out) I've noticed a huge difference in it's performance.
I didn't do any porting - just straight outta the box Allukit with HiComp head - I did get rid of one obvious little burr that was sticking up but that's hardly porting...
Thanks again for this setup and for reals - this setup turns heads and is spreading like fever over here - my neighbor and his brother both seriously want to do the same upgrade... so we may be contacting you again...
All the kids running dirt bikes and little gas mopeds in my neighborhood can't understand why it's so fast they keep asking me to ride it, sell it - HELL NO! Now they think my neighbors garage is a moped shop... and ask us if were open (while were kicking back a few brews on the stoop after work)...
