98 polaris 780 slp big bore

[drewsky8611]

Just wondering what this kit was like, any problems with it?i just bought an older rmk and did a little research on the motor and called slp with the vin # that was stamped on the jugs and it happens to be a 780 big bore kit. slp built the motor and I just wanted a 2nd opinion of these motors although the motor runs amazing. what do they use for clutching at sea level? its curently got r-6 heads from slp that are set up for pump gas @ 6,000+ ft but you have to run 110 at the elevation that I will be riding. any additional information would be awesome! just trying to learn a little more about it. the motor may be for sale sometime since I already have 4 other sleds around the shop.

thanks! Drew

forgot to mention it is also ported and the cylinders are decked.

The one we had came with specific instructions not to run it at low altitudes.

I want to say that Max at TriCity in Utah was the main tuning source for this motor.

It ran great... then the 800s came out and a ported and single piped 800 would run away from it so it wasn't really a cost effective option any more.

Call Tri-city in Utah, as of a couple of years ago they still had the full tuning specs.
