Why are you running Opti-2 at 70 to 1 and 80 to 1?
Mix it at 100 to 1 just like Interlube recommends.
I have ridden 2 of Baird's 100 to 1 66 cc two stroke bikes and they are
some of the fastest and cleanest bike ever. Lots of miles on them too.
GPSed one at 54 mph with a 28 tooth rear sprocket!
Opti 2 really works and the next 2 stroke I build is getting 100 to 1 Opti
from mile one. It will be broken in using their recommended technique.
It was going to be my secret weapon with the 4 strokes too but seeing
that Opti-4 is sponsoring the race at Willow Springs the secret is no more!
