This girl is a 2004 carb titanium. It has twin SLP pipes with a SLP air box and not sure what else... have not gone through clutching or carbs yet.. its a work in progress. I picked it up as a basket case after it made a sudden stop on a stump on a pipeline right of way. I'm trying not to get too carried away here. (I've been known to do this) The new primary function of this sled is ditch banger/toboggan puller so it does not need to be tweaked right out.

I should of explained on my last post, this is if your running the carb. version. If your running the EFI version, then yes you are limited to the single pipe as it doesn't adapt very well to twin pipes.
I had the carb. version and it was also the last carb. sled i ever owned.

Thanks for that ......

Actually these engines are not DOO's. They adapt extremely well to twin pipes. In fact you can easily get into the 165-170hp range and not imaginary hp like a lot others claim.
Use D&D pipes with V-force reed and reed spacer. Simple rejet for your area and clutching. Bang, your running a reliable solid 165++. This was the #1 setup for mountain application on the 900 stocker mountain Cat out of CR-racing.
It worked so well that it would pound any 800 at the time including the HIGHLY over exaggerated and underachiever BRP RT1000.

The biggest issue these engine had was the crank would come loose. Stock you could get mileage but any mods would stress the crank. It would require you to weld the crank, once welded the were pretty much bullet prove reliable.

Mine 800 had SLP Twins, V Force Reeds, and spacers, high compression heads, porting, oil injection delete, trued and welded crank. Attack 20 track in hillclimb position and straightened lugs. Thing would rip your arms off it had so much bottom end. It started burning coolant and I couldn't stop it after taking the motor out 5 times, I gave up on it and sold it for cheap. Guy took the motor out and put in his 900 king cat motor with a bunch of crap on it too. Don't know what happened from there.

i think union bay dyno'd that particular motor at like 170hp, but that's running AV gas, not bad for a 2001.
