Hey guys! I'm looking to find out what is exactly on their kits.

Can any of you give me some info? Want to buy the kit but don't know the specs.

core exchange and else, piston valve etc....

Any help will be much appreciated.

Thanks in advance

Talk to Mickey D at FST if you want his kit. His web page pricing is out of date and he has been hard to get ahold of lately (holidays?)

We just got started making new style head gaskets so we can build 877cc motors with resleeving the stock cylinders and with out boring the cases so it's still just a top end rebuild.

Thats gonna be sweet! Whats the expected life on these motors? Are you gonna have to pray everytime you turn the key?

These V-Twins have been soild as a rock with little or no problems. The Teryx is a lot bigger and we might see something happen that we didn't on the quads but that would be easy to fix too. I'm talking about gear box problems,but we already have a fix if needed. As soon as the new head gaskets are done we will have a 1000cc stroker kit that might need our oil cooler kit, but so far I have not had any feed back from the dunner guys that we need it on our 840's

I plan on doin a 840 kit in the future and I'm a big time duner. You guys will definately get my business. Can you recommend any good motor shops in AZ other than Weller?

Dragonfire can do it,or I have about 5 other shops out there that have done my kits in quads.

When you do this kit, you don't have to split the case or anything do you? Its all top end work right?

Up to the new 877cc will be top end only labor, the 1000cc is a stroker and the cases have to be split to do that and to bore the cases for the bigger sleeves.

any idea on pricing for 1000 stroker engine after all said and done? What about the 877?

It all depends on what all you want, parts wise on the 1000cc motor with out carbs or porting would be around $2500 (stroker,HD long rods,cams, valve springs,pistons,sleeves and head gaskets. The 877cc about $1050 less because of the stroker and rods.

On both these kits however 39 to 41mm carbs and 4mm bigger valve heads is where you are going to bring both the HP and cost way up. HP cost money,how fast do you want to go?

So how big do you have to go to make a Teryx keep up with of a Brute Force 750 with a pipe and CDI?
almost 1300 lbs vs just over 600lbs.
