as the title says I need help between vp-c12 and vp-110 octane. I have been running c12 since I got the kart but the 110 octane is much better as far as price . Are there downsides or cautions of running vp-110 over go-c12?
Part numbers on the piston. Have a look at the cylinder to see if its been ported. Check the squish. I’m not really familiar with the Hondas, but that’s generally how i’d check any 2-stroke to see if it’s been worked over.
