my brother has a panterra from 2004 and i wanted to know if it had the same bore and stroke as a honda 90 if so were can i get a big bore kit thats for a honda but would fit a panterra, and a pipe

 

I have a 90cc panterra, too. Im willing to bet that its just a knock-off of honda so the kit may work. i personaly need a totaly new engine because i love the river so much and now it looks like my engine got shot with a shotgun because of all the holes in it. rofl

 

im going to get a trx 90 exhaust from big gun for it
