Crankshaft Rebuilds
Owners of Yamaha TZs facing bottom end rebuilds have the option to have their crankshafts rebuilt rather than purchasing a brand new crankshaft. The Honda RS125 and RS250 do not have a crankshafts that lend themselves to being rebuilt, and replacement components (ie. the connecting rod) that meet specifications are not readily available.

MCE rebuilds TZ crankshafts to the same exacting standards performed in all other MCE projects. MCE understands the demands placed on the crankshaft in a grand prix racing engine and rebuilds crankshafts to the proper tolerances and specifications. If the crankshaft isn't as good as it could possibly be, then it doesn't leave the shop.

Pricing:

Yamaha TZ125$250 USD ($100 parts, $150 labor)
Yamaha TZ250$730 USD ($380 parts, $375 labor)
Honda NSR500V$780 USD (labor only)
