What would be your choice to pep up a 357xp? One or the other. A 47mm big bore kit or a higher comp piston.

The 199 is fine for all but a race port.If you port and or bore and do a muffler mod, seems a bigger carb would be in order so more air can flow through. Seems if you open up the back end, you would need to also open up the front end as well.

ive seen saws with pretty crazy compression that run just fine on pump gas. this to me is an overblown concern on the relatively small chainsaw combustion chambers.higher comp might require higher octane fuel depending on how high the comp would be.
How tight was that squish?ive seen saws with pretty crazy compression that run just fine on pump gas. this to me is an overblown concern on the relatively small chainsaw combustion chambers.
seen 50cc saws blowing 240 psi run just fine on 87-89 octane.

.020 ish. big long cuts would starve it a little bit. my only point is that the octane thing gets talked about a lot, and ive yet to see a saw that truly benefits from high octane fuel.How tight was that squish?
ive seen time after time, vids of people disproving the idea that “race gas makes a stock engine faster”. seat of the pants feel is not a replacement for a stopwatch.In the motocross world 50cc bikes with high compression run race fuel up to 110 octane. Just thought it may cross over to the 50cc chainsaw world. I have ran VP U4.4 (105 octane) in my saws and have noticed an increase in power and torque over 93 pump gas, in a stock saw. Quicker revs and it doesn't bog as much under a load ether.
