Product Description
Bore: Yes
Stroke: No
Actual Displacement = 478.23cc
Includes:
Cylinder bore and re-plate with Apticote 2000
CP or Wiseco Piston kit - Your Choice
Necessary Gaskets
Notes: This is a 98mm bored and Apticote 2000 plated OEM Yamaha cylinder.
At 3mm over it is starting to push the stock casting to the edge, however it remains quite reliable and we only really see issues when customers try to run stroker crankshafts with them. In other words, with a stock stroke they work well, add stroke and you will have problems.
It is a good choice where you need to rebuild the engine, want to bump the power, have limited funds, and do not want to add stroke later down the road.
Max Power's Apticote 2000 ceramic bore coating is the best available and Max Power's plating craftsmanship far surpasses the quality of anything else out there. (Just ask builders like Pro Circuit, Duncan Racing, ATP, Rossier Engineering, CT Racing or any of the factory teams- We plate cylinders for all of them).
This is the largest bore on an OEM cylinder (without a thicker sleeve) that you should use.
