(96mm)  We really only do these for the 2004-2005 models with the OEM cranks.  It makes them a “true 450” and they actually run harder than the longer stroke 2006-2008 versions with the longer stroke.

(97mm)  We LOVE this kit.  Totally durable and runs really hard for what it is.  Bang for the buck it is 100%.  You can run this with the Hot Rods +3 (YFZ491) or the Max Power 68.2 stroker (YFZ504).

(98mm)  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. This is the largest bore on an OEM cylinder (without a thicker sleeve) that you should use.  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 Ceramic Nickel Bore coating is the best available and Max Power’s plating craftsmanship far surpasses the quality of anything else out there.
