Use a torque wrench when tightening the bolts. You can find the torque specifications in the the Yamaha TW200 Service Manual, which you can download at the following link.

I was gonna do the top engine rebuild but after watching spud´s thread I felt a little bit overwhelmed. I will pay someone to do it for me (any shop willing to take my money)I will drop by or call available shops to find out which is better and cheaper. Replacing gaskets will cost me around $73. After two months of oil change and 300 miles, I check the level and added about 100 ml for the proper level. I think the engine leaked too much oil after 2 months and want to fix it ASAP.
