i am getting my engine redone which includes brand new 20 over bore wiseco prolite pistons and rings and wrist pins and circlips, a 20 over bore on both of my jugs and a new gaskit kit. after that said and done i was wondering are you supposed to premix your gas and oil along with the oil injection to break in the engine just like the brand spanking new machines do

I agree with Bob. When new sleds are shipped they have a paper on the gas tank filler neck that says to run a 50:1 so the engine is properly broken in.

I'd go 50:1 for 2-3 tanks. I don't think it would hurt to go with a richer 32:1 mixture for the first tank.....It'll just be a smokin!

I'd just run the 50:1 for 1 or 2 tanks. It smokes like crazy when you have the premix and the oil injection goin though.

You'll want to change the plugs once you start running straight gas. Whenever I break in my sled or motox bike I'll run it rich for only a tank or less of gas. It's the first hour of riding that counts the most for the ring pressure being changed. After that it's time to go play!

Questions questions questions :)

Yes, premix at least the first tank. There is usually air in the oil lines after a rebuild, from disconnecting and reconnecting the lines. So do it for this reason, and for extra lube during the break-in.

I think 1 tank of premix is more than enough.. 2 strokes are hard enough on the eviroment as it is.. they don't need any more help..

I've always mixed the 1st tank at 50:1, and just took it easy on it for the first 300 miles or so with normal break-in throttle. Never had a problem yet with that method.

just toss in a qt. of whatever you use for injection (for 10-12 gal. gas) and dont go over half throttle for first 50mi. after first fill up change plugs,check injector cable and be done.

two strokes like rpm's so break it in like you stole it, it will seat the rings and probably (if you keep it jetted properly) run forever!!!
