What was the difference between the $2,300 and $3,000 version? I assume this is shortblock vs longblock.

New engines are so pretty.

Update: Never got many pictures of the re-assembly, wouldn't all too bad. The most misery if you ask me was re-attaching the oil lines to the bottom end, routing the stator wiring and vacuum lines for the raves. Sled is currently at the dealer awaiting to be hooked up to BUDs to get everything set up to fire. Anxious to see how it goes!

I'm unsure to be honest, The crate this engine came in said on the tag "shortblock with head" which makes no sense to be really. It's a longblock if you ask me.  This is the $3000 option, I insisted on getting the shortblock without the head but I was told they were unable to get me one. Unsure if it's discontinued or what the deal was there. :unsure:

Another follow up, Sled is up and running! Install wouldn't all too bad aside from getting all the wiring/hoses routed correctly. Dealer surprisingly only charged me $60 to program both new injectors, bleed the oil pump, set the raves and put it in break in mode.

Slapped on the 1+1 seat for a ride with the girlfriend tonight and put a lil over 30 km's so on the new engine. It's running great so far! Hoping it stays that way. Only bug is my starter seems to have died, but i can live with that for now.f683220d6d4dbda425005a21ddc36c95.jpgc1f42410fb5633e7fac9c1d6cfe73de7.jpg

"Only bug is my starter seems to have died, but i can live with that for now."
 
I wonder if this is the same symptom that kept the battery from charging and led to the injector not fueling the mag side correctly. I remember two new injectors were bought on e Bay and the stator may have needed to be replaced. In any case it is worth testing the 12Vdc and 60Vdc systems, and also ensure the mag and pto sides are burning evenly. Those are two of the three things I use as an insurance of sorts.

I actually broke out my multimeter and tested both as soon as I got it back and running, all ok and the battery is charging right where it should be at 14.3 +/-. I did replace the stator as well. I think that the starter issue maybe a coincidence, I'm pretty sure I ruined the starter the prior day of it blowing up trying to get it running at -35 temps. (I forgot to bench test it in all the chaos of putting it together.) Electrically everything checks out fine right to the starter but it's a no go.

 

So far nearly 100km's on the engine and its been running excellent. I have been taking it easy on the engine, My plan when I get a few more km's on it I'm going to pull the plug's and see how they are burning.

You really did take all precautions on this build and I think you are off to a good start. The only thing left will be to check the bolts for looseness after a certain amount of riding. The ones that I find are prone to loosening from vibration or heat are the battery connections, the y-pipe bolts, the nuts holding the RAVE guillotine, and the clutch bolt. It is worth giving the 3 ground points a quick check too.

Stumbled on this thread and find it interesting so will make a few comments on my experiences with P-Tek not E-Tek, I have done several doo 700, 800 original twins and several P-Teks. I used to have a local buddy that did cranks and could buy Weisco pistons fairly cheap which is how original builds were done. However the original engines were always taking out con rod bearing and sometimes resulting damage quite often required rebuilt cylinder. These problems increased cost. I have also gone the CV-Tech way with a rebuild. For my own P-Tek I bought Doo shortblock for about $2200, and found that no way was this a REBUILD, several places on block that Rotax uses self tapping screws ( intake and stator shroud ) had no threads in them??? Got to thinking that doo goes through so many of these engines that not worth there time or effort to rebuild. No way these would make sense being done in EU by Rotax, and doubt very much they would reman in Valcourt. Cores I'm betting all go to CV-Tech. The last one I did for a buddy we were able get new cases, his were damaged from con rod, and rebuilt crank for $900 plus some shipping. Luckily monoblock was okay so weisco pistons and gaskets etc was about another $500. So in the end with my free labour engine ready to go in sled, he was in for about $1500. Now keep in mind he bought 2009 Summit knowing engine was blown I think for about $1500. So he's in now for $3000. for a sled that is worth not much more than that around here. But if he can get enough use out of it it will be affordable. The moral of this story is I truly believe that a crate engine from Doo is by far the best way to go if anybody plans on using sled lond enough to justify $2500 ish if they can re & re themselves. I believe E-Tek is couple hundy more than P-Tek but in most of Canada probably $25ish.

Around $3000 all said and done for this engine (that's with the core return.)  If i have more time and my own garage to work in, i would have rebuilt my old engine in a flash. But i don't regret this choice. I had my sled back up in much less time plus the warranty on this one gives me peace of mind. All in all if i had known this was going to happen, i would have been far better off having a brand new sled instead of trying to save a few bucks. But that's it, it's the gamble you taking buying second hand.

 

As of today, 250km's on the new engine. running excellent :D

How much was the core charge?
