Recently, I changed the timing chain. I lined up all timing marks and set valve lash at TDC. The mark on flywheel was on point as well when I looked through sight hole. I started the engine and starter turned it over then it hit and stuck. I did it one more time and the same thing happened. I took everything off and saw no damage. I tried to turn it over by hand and same thing. It turns halfway or so and hits. I loosened valve lash and took crank gear off and it does the same thing. It will turn over clockwise fully but not CCW. It seems like the crank sub assembly weight is hitting the gear balancer weight. I can turn crankshaft CCW while turning the gear balancer CW and get it to go but feel it hitting something. I also can spin crankshaft CCW without crank gear on and force the engine to break past the stick. It’s not the piston.
Please give me some suggestions thanks

Hello all. I have just stripped down the carb on my YFM225 as it is not running right.
I put it in the ultrasonic cleaner for half an hour and it has done a good job.
Nice clean jets but when I go full throttle it backfires, and there is a lack of power.
It also does not seem to take fuel in properly - it comes out the petcock ok so it is running freely enough, but it is not drawing into the carb.
If anyone has any ideas I would be very grateful.

This is more of an informational fix I wanted to share..
My Grizzly has been getting harder and harder to shift this winter and today was completely stuck and I needed to plow the few inches that came down this morning. First thought...oh no, tranny...but it’s winter and maybe it’s iced up. I pulled off the plastic to see what was going on and indeed I did find the drain tube iced up.
I took the blow dryer out and de-iced it. Quick fix, I never really thought about the shifter drain tube icing up before, shifts like new!

What's the best way to fix this?...
Best idea so far is to clean it all up, sand the bottom side real good and find a piece of durable plastic I can shape and form to the bottom, and sand it as well. Then hold it all together somehow and epoxy the formed plastic to the bottom side. After curing, drill holes on both sides of the crack and thread wire through like shoelaces for support, pull tight and tie off.
Seems like I read about some kind of goop you could use in this situation but I forget what it was called. I believe it would take the place of the epoxy.
Right now I need advice on what kind of plastic to use and how to source it, as well as what kind of epoxy.
I'm all ears.
pick-up coil died, maybe reg. caused it to burn out? If any one has resistace values and color codes how to check reg. i sure would apreciate that info. My computer can,t download service manual
