2000.5 Mille-Just wanted to put my 2 cents in (some of the info is in this thread, some in others, some not).. I found out after going to 6 hardware stores, and a bolt specialty shop that is very hard to find a bolt to use as the TDC locking tool as it has to have threads from top to bottom, I finally just went with a piece of all-thread, the size is M8 and needs to be 1.25 pitch and at least 100mm long (80mm will not work). I hand tightened it as far as it would go. I used a drinking straw in the spark plug hole closest to the stator side to get close to TDC first. Then if you lay down next to bike on the stator side and reach one had under to the other side, and try to keep slight turning pressure on it, while using the other hand to slowly turn the flywheel, it'll click into place(reminds me movie where they line up the pins to crack a safe.) Then just go to the other side and screw the bolt/TDC Locking Tool/All-thread the rest of the way into the crank and wah-la. The v990 manual says not to use an open flame torch on the flywheel, to use a hot air gun for 5-10min. I had both, so I figured I'd try the hot air for 10min first, and it came right off using about 30-40lbs with a 1/2in drive breaker bar. And found, after it cooled!, that all my gears we're fine and tolerances within spec. My sprag was so worn out though, that the I could easily pull the spring off holding the bearings. I used the KTM sprag, and the pemetex threadlock equivalent. I put it all back together and it works like a charm, stonger starting than ever. I would recommend that after everthing is back together to let the threadlocker set up overnight, you can also use this time to charge your battery up. Well my two cents turned into like a buck 25.
