change your 450sxf/xcf into a 505

Recommended Posts

I am going to have some pistons made that will change the 450 into a 505. I'm tired of waiting for one of the aftermarket piston companies to do it. These will have the smaller wrist pin so it will be a strait change out and overbore. I would love to go bigger but the cost would be high- in the $16-1800 range. If there is enough interest I will have a bigger batch of pistons made which will keep the cost down to about the same as the old 540 kits for the RFS. If not it will add about $50-75 to the cost

My son may be interested I will let him know. Hey Travis is there a way to add a 5th gear to the 08 SX450? Thanks, John

Come on Travis, we NEED 550cc!!!

Jim

To get to 550 one a big bore short stroke engine, well the piston would be wider than the gas tank and will wear out your boots as it goes up & down

Way to step up I'm very interested I hope you have enough demand for the kit to keep costs comparable to the 525 to 540 kit. All the reviews and comments about the 505 vs the 450 make this sound like a great way to boost power with reliabilty for the $ spent. I will be giving you a call when my top end is ready for a rebuild and go with your kit.

regards

Sounds like a great idea as 505s are no longer available in canada.I was wondering what to do when my current 505 needs to be replaced,I couldn't possibly go back to a mere 450.Too bad you couldn't make it a true 505cc's.That would be incredible!
