What’s the Best Top End Kit for a Bear Tracker?
-
Hey there all, First off thanks for the board. My Bayou 220 has survived 3 teenagers and is on its 4th now. Up until recently it has been a virtual tank....until I decided to fix it;) Noticed some smoking from the engine block (not exhaust) so figured it was time for a quick top end rebuild. Now that I have it all back together, it fails to start. I've pulled the starter rope until my arm is tired. So I will be as detailed as possible and hopefully get some help. Completed: -New Head gasket -New Valve seals -New piston (standard) -New rings (standard) -All new seals -Cleaned up head and valves (didn't do any resurfacing, as it all cleaned up pretty easy) -All torqued to spec -Piston ring gaps all checked out -Valve clearances (Intake: .18mm, Exhaust .20mm). Not too tight, not too loose. Pros: -Engine IS making decent compression -DO have spark -Will fire for a split second if I drop some gas in the spark plug hole and pull start. Will NOT from carb and or intake valve. Timing: So I followed the guide of: TDC -Flywheel aligns on the “T” mark on the engine site hole -Cam gear mark aligned with the cover mark Seeing as this is my first time doing a top end rebuild on an ATV. Here are my questions and concerns: -I didn't realize (dummy me) that there are 2 TDC's. 1- Compression, 1-Exhaust. How do I know if I'm on the right one? -Does the cam need to be aligned a certain way when put back in? I just aligned the cam gear dimple with the cam and put it in. No alignment. Thanks ahead of time. I feel like I'm 90% there, but I'm missing an important step for completion.
