I got a 4mm stroker crank and a 20cc stroker cool head. I should be getting my cylinders back at the end of the week. I got the bored to 64.5 and retimed for the 4mm stroker crank. I also have an fmf exhaust and silencers. Im not getting any port work done this time but what should i expect from this setup? Should i be able to beat 450rs? Also the bike has reed spacers, do they make any diffence? Should i keep using them? also are my pipes good for a stroker motor?
