Hello Folks....new to the forum. I have two Warriors (87 and 92), and an 89 Big Bear. Looking for some help with engine issues on the warrior, and my 89 Big bear backfired and died. Got spark, got gas, seems to have compression, (but haven't tested it yet...next). She rolls over good, maybe too good...seems soft. Have spark and enough compression to blow gas mist out the plug hole when cranking. Suggestions, Been running great since we got it.
Hi, I just bought a used 1990 warrior and the rear is sagging low like it has a lowering kit but I’m not sure, does anyone know what it could be?
Hello everyone !
I'm currently rebuilding my carburetor on my Yamaha moto 4 350 1987, first time I rebuild a carb 😅 ! It was leaking fuel from the overflow and inside the intake ....
When I took off needle (the platic top part was stuck like crazy) I had a spring and inside the kit there is a spring, an O-Ring and a washer.
Left is the needle that was in the carburetor and right is the new set (I already tried to mount it but it didn't felt right and I accidentally broke the o-ring)
Anyway, I saw in some videos and diagram that there is no spring in here. So should I put the spring back ? And where ? On top of the needle or bottom ?
This is an original Mikuni carb :
Thank you ! Also if you have any additionnal tips please feel free to share I want to learn the proper way !
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.
