Just Rebuilt 02 800 Summit Highmark

I'm breaking in the motor and put in a little oil with the gas and took it out for about a 2 hour trail ride break in. The guy that did the work put in V-force 3 Reeds, SLP pistons rings, shaved head a bit. Does anyone know what the jets should be set to. He said there is some adjustment for fuel intake and he adjusted it one notch up. I didn't really get on it hard yet but when I did get into the higer RPM it might be sputtering a little. Since I was breaking it in I never did just pin it. I took a look at a forum about breaking these motors in and I think I'm going to start riding it a little harder next time out. I have put about 15 to 20 miles on the first ride. Varied speed the hole ride, no road ride. Any comments or suggestions or things I should be keeping an eye on would be appreciated. I had posted a thread a while back about best mods for an 02 800 summit and this is what I've finally did and I think its turned out pretty good.

Big wheel kit
16 inch wide track off 04 rev 151 instead of 15 inch stock 151
SLP Pistons
SLP can
Shaved head a bit
Drop down brackets
simmons
Removed some rollers

So far after my first ride I'm pretty happy seems to spin a bit less but I don't know about the power side yet. I hope the motor ends up in the 150 range. Mid range has been great. Handling is good also. I will try to tell you more later after the visit some steep and deep.

Good luck and have a great snowmobiling year

two ring pistons

Thanks for the info. We have another foot on the ground and I can't go ride write now. 2 feet of snow is a perfect break in.
Going to check on the thermostat asap. Did not know this. What is your thought on removing the oil reserve. I am going to switch to marble blue first and see with this new motor if I still go through plugs ever 2 or 3 rides

how do I know if my suspension is reloacated right?

when we pulled motor we had to nickel one side

Had to send one side off to be nickel plated
