"80cc" is actually about 65cc, as most dealers are now admitting.
all the HT's have the same stroke, but different bore...for some reason, the (constant) port-timing seems ideal for this bore size.
we ran a sample 65cc up here once, did 37+mph (44t) right out of the box...i mean it wuz sca-reamin'! almost right away, we knew what to expect...it blew itself to pieces in under 300 miles...the typical "needle-bearing-embedded-in-the-cylinder-wall" trick...we eventually deduced that not enuff lube gets to the underside of the HT piston.
use 20:1, and be as conservative as is possible for you.
yeah i broke it in on 14:1 and im still skeptical about the 20:1 i run it on now, i mean there is little to no smoke coming out the exhaust but im positive its 20:1. would using higher octain gas and more expensive synthetic oils doo any different? ive come 2500km on the original spark plug and standard 84 octain shell gas with the 4 bucks a half liter oil. also how do these engines fail? when it goes on me will it just loose compression like my old honda motors, or will it explode causing me to crash and most likely die?(sarcasm)
