04-05 Honda TRX450R 511cc Engine Rebuild Kit

This kit is great for duners, hillshooters, drag racers, and trail riders. This kit provides a Torque and HP increase that cannot be matched by any other kit on the market.

This Kit includes:

-JSD Machine Works 4.2mm Stroker Crankshaft. This Crankshaft is an OEM Crankshaft that has been modified to increase the overall stroke from stock 64.8mm to 69mm. We then use a Custom Stock Length Carrillo Rod and Pin and Bearing from the OEM Manufacturer. The Crankshaft is pressed together, trued, balanced, and welded. We hold our Stroker Crankshafts to very high tolerances and don't let any crankshafts leave our shop without meeting our strict standards.

-97mm CP piston. You have the option of 2 different compression ratios for this kit, 12:1 or 13:1. These Piston are designed for the 06+ TRX450R and 02-08 CRF450R by CP. This pistons are off the shelf pistons available straight from CP. They are a 2 ring design to get lighter weight and less cylinder wall friction for more Torque and HP.

-97mm 04/05 Standard Height Big Bore Cylinder.

-97mm Cometic Top End Gasket Kit. These Top End Gasket Kits are the top gaskets available, and all we use for all our big bore and stroker applications.

-OEM Main Bearings and Seals. We include OEM Main Bearings and Seals because they are the highest quality bearings available.

-OEM Cam Chain. The OEM Cam Chain is included because it is of the highest quality available, and it is all we run in our own engines that use stock length cam chains.

-OEM Bottom End Gasket Kit. The OEM Bottom End Gasket Kit is the Highest Quality available for the Honda TRX450R. They do not require any RTV silicon to seal any matting surface and include all the gaskets, O-rings, and sealing washers needed for the entire bottom end.

-OEM Spark Plug seal, Valve cover bolt seals, and Head Cover Gasket. These OEM Parts provide and Complete Top End Gasket kit when combined with the 97mm Cometic Top End Gasket Kit.

 

This kit is a complete drop in kit and requires no modifications to the crank cases. Other Modifications such as Head Porting, Camshafts, Valves and Valve Springs, Intake, Exhaust are not required but highly recommended to get the most power and Torque from this kit.
