Was at the mechanic to change sprocket and chain for my DRZ400SM. Mechanic told me to look at him changing the frontsprocket as the gear shaft is easy to break as old DRZ model have a big hole. So he untighten the nut, took out the sprocket and insert the new front sprocket. As he was going to tighten the nut, i was looking at him doing it and when he uses the airgun to tighten it broke. Causing the nut and the threaded part to be together. Now the shop is saying that i have to overhaul my engine. Any advice people? My bike is currently in the workshop and would appreciate if someone can advice me if overhaul is really the right step or can we just change the gear shaft or something? Overhaul ($899) + counter shaft ($280).
Do contact me @ 90608415 urgently as they will start overhaul tomorrow.
