CT Racing Baja Top End Motor Kit.

’04-’05 TRX450R Baja Motor Package >>> $1459.95

This kit has been updated and now includes valves as you will see in the details.

This kit is perfect for a durable performance quad that can still run on pump gas, although if you have us bump it up on compression to run 100 octane minimum you will gain some snap off of the bottom. We choose the cam after conferring with you on Fuel choice, and racing or riding application.

Just ship us your complete top end – cylinder and head that’s all we need. Labor to disassemble and reassemble the head along with honing the cylinder and setting the ring end gap is included as well.

PLEASE NOTE: Your head is returned assembled and ready to bolt on and run. This kit price is for you shipping us your top-end only. If you would like to ship us your complete motor, add $250.00 for R&R of top-end.
