I bought a set of yamaha rims to replace the purple ones on the blaster i am rebuilding. the new front rims fit the current lug pattern but the rear ones dont fit. The old rims were 8 inch and the new rims are 9 inch. My question is: Can you get a different rear wheel hub that will fit the bigger wheels or am i FUBAR? It look like the patter on the hew rims is about an inch wider than the original. Any help would be greatly appriciated.
