Sled again…

      No Comments on Sled again…

Got the compression tester a day early.  I was in a hurry to check things out so I rushed out to the garage as soon as I got home after work.  The good news is, there is still compression (as was obvious because it started…) but it was quite a bit off from what it should be.  The outer cylinders registered 110, while the inner cylinder registered 90.  If they all came it at 110 I would have run it the rest of the season and rebuilt it this spring/fall.  Since the middle cylinder is so low it’s gong to need a rebuild before it’s ridden.  I’ve never tore in to an engine before, so initially I wasn’t sure if I would be able to do it myself.  After watching an online video of some garage monkeys rebuilding a skidoo, it’s something I can do.  Looking at the kits available, it looks like the rebuild will cost me probably $450 in parts and tools (torque wrench…that I should already have tbh).

I’m struggling a little bit because the sled in top running condition is still only worth 1k.  Just like everything else though, I can’t ride around on stacks of dollar bills.  If I did end up buying a 1k-1500 sled then I’m dealing with a new set of problems.  I also looked around and it looks like an engine is going to be about $900, plus some shipping.  That engine probably has 2500-4k on it, while the one in the sled had 2k on it.  That really doesn’t matter now though if I rebuild it.

Of course this all depends on the crank shaft looking alright.  I’m not going to be able to fully inspect it, but I should be able to see any huge defects.  Also, I’m concerned about the cylinder itself.  Chances are I’ll have to replace the middle one…so probably $150 or so for that.  I could try to get mine honed…but I’ve no idea what that does to the parts I need.  I’m also going to call a couple of shops in minot and see what they quote for a rebuild.  I’m guessing $700 anyway…and that’s a little too much for me.

Who knows though,  might tear the heads and cylinders off then see that things are gouged all over the place.  I might pop things apart on Sunday.  I’m so damn impatient…
