Bad Rumble!!!

[Wombatclay]

Hi ya all, great turnout for the first cruise.....great snags too, just recently I had new tread installed & under acceleration I get a nasty rumble from the rear end............happens worse when I get more traction under acceleration, any pointers as to what it is & how much to fix it would be great!! it's a VR Calasi stock appart from aircleaner & spark plug leads.....

happened after the new tread was put on? if it has, maybe one of the wheels arent on right, or they werent balanced correctly, go back to where you got them put on and see fi theyre supposed to balance wheels with new tyre fit, if so, tell them to redo it.

they balenced the wheels nicely, cruising has no shakes or rumbles, just under heavy acceleration from a stand start.......
