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.
-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.
-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.
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.
Looking for advice on what to try next I bought this quad and it’s has spark and fuel but won’t stay running only fires when I hold the starter button in even when spraying gas into the carb it still dies right away oil was milky white so I was thinking it maybe went under water 150 psi compression so I might be wrong but not a head gasket I am stuck Cause it should stay running with the straight gas through the carb so what should I try
I’m just wondering what year bike i got? it seems the vin has been rubbed off i got it from a auction here in Australia engine starts but seems has a dirty carb wont idle well
and also has a problem I put it in gear and makes a grinding noise but does not move it the neutral light goes out but then when I change gear it grinds more in the higher gears as well I’m guessing the differential is stuffed so wanting to buy new part for it will start the pull down next week
this is the first bike I have worked on used to dealing with cars
