you will be surprised at how easy this task actually is.
You're damn right! lol
Piece of cake. I wasn't there when he drove the wrist pins out, but, it's done. lol.
Only took 3 pulls to get going, fired right up and ran great.
Kept the choke on for about 30 seconds, let it warm itself for about 2 minutes. Light drive around the backyard to get to operating temp. Let it cool for about an hour and a half.
Brought it to the trail, warmed it up, and the rode hard with varying throttle to seat the rings. I am a firm believer in the heat cycle and ride hard theory. After owning quite a few things with motors... always trying to find the best way to break a motor in, I think this is the best way. Yes, there's plenty of people that think otherwise, but I believe that to be oldschool.
The whole idea of leaving the motor running and running through a tank of gas at idle boggles my mind. No stress on the rings to seat them, and on top of that - no air or snow over the coolant to keep from overheating.
I broke my car engine in with the heat cycling/ride hard method, and I just pushed over 100k with nearly stock compression still. Pretty pumped about that.
Now that I know how damn easy this is on the 600 twin, I'll be doing my sled next!
$80 plus fluids is a fantastic deal for a new motor! ($20/set rings and $20 each gasket)
QUESTION. What do you guys expect for compression on this motor, and how long before I should test that? (will the rings be fully seated now after an hour ride, or should I wait for two more rides or so?)
FYI - the motor was 135 / 115 psi before we went out the other night. When it started running like junk, we checked at home with a hot motor - 125 / 90. Can't wait to see the new numbers!
