race kart

i'm pretty sure that is an older hpv100

its air cooled, so chances are its not a 125. i used to race karts, we had several kt100 engines, a tag parilla leopard 125 and one hpv100 engine and that looks just like the hpv. we never ran the hpv because the crank was out of wack but i heard they are pretty strong engines. and i've never seen an air cooled 125 on a kart
 
thats what im doing now is racing karts on dirt where do you plan on racing it, its looks to be a margay chassis
