Ok, so i've been having this 212 vibratiion issued. at idle, the whole bike is vibrating badly. I put on isolator and add a few supports bar and gusset but it is still vibrating quite a bit. The only time that i didn't feel any vibration was with the isolator loosely bolted. I'm not sure if it's a bad motor to begin with or it's an idling issued at this point. I had it idling on the ground and it jumps up/down about 1/4" to 1/2" off the ground.
The motor had 18lb spring, billet flywheel, and a gx390 carb.
