    2000 Yamaha XL 1200 LTD rebuild.

    New to the site and wanted to get some ideas on what I should do to my ski. I'm going to have to do a total top end rebuild on my 2000 Yami 1200 LTD and wanted to know while I was in there what all I should do to make sure my ski is running amazingly. It's all stock with the exception of a D plate. I'm going to block off oil injection and go to premix, rebuild my carbs. What else should I do/adjust/change? Thanks for all input.

    If your ski has the power valves then get you some Waveeater clips.

    Make sure you check the crank, it seems to be a weak link in these motors, and i had to change it as I am getting the motor rebuilt now. YOu dont wanna just do the top end and then havbe the crank fail right away and tear it down even more again.

    3rd piston blew out on me, broke the sleeve as well. Wasn't getting enough oil in that cylinder. The front 2 looked like they were getting very little oil also, but they seem to be fine. Metal all over the place, crankshaft is ok believe it or not. Here are some pics...http://img89.imageshack.us/gal.php?g=dsc04439n.jpg, http://img404.imageshack.us/gal.php?g=dsc04451.jpg

    The crank is also fine, I think I was lucky considering all the metal that was bouncing around down there. When the sleeve broke off it jammed that piston and shut it down right away, good thing or else I probably would have had a lot more damage.

    Anytime the crank stops quick, it's a good idea to check the index. A hard stop can and will twist it out of alignment...it is NOT something you can see by eye, or "checking it over". I'd hate to see you get it all back together and then find that its burning a cylinder down due to an out of index crank.
