Bought a 05 TRX 350 basketcase. Guy said he redid the top end but " put it together wrong" and tore up a pushrod. Had all new parts including a cam...My only conclusion was that he forgot the lifters. This due to the way the rod was dinged and the marks on the old cam. So I put in all the new parts, adjusted the valves and during rollover with the plug out, I keep hitting a hard spot that requires a pretty good push on the wrench to complete the rotation. Is this due to the compression release?

Does it occur at TDC?

 

[bobodu]

Oddly enough...on the way down !

Exhaust valve or guide bent/sticking?

 

[bobodu]

Sheesh...I just notice that the cam gear was wobbling around !! Guess I might as well buy the flywheel puller.

Hate to hear it but like that you found it.

Happens near the bottom of the ignition stroke...valves are moving just fine.

Trying this!! https://imgur.com/a/eu8Jz
I ordered a flywheel puller. The local shop is a bit strange.. I did not see a broken case when I installed the new cam.

Wild guess , problems with the crankshaft , the piston is cocking at the bottom of the stroke , it tore up the upper rebuild that was done back when cause it needed a connecting rod but didn't get it

 

[bobodu]

Except the crank and piston work beautifully. No wobble or lateral play at all. That would not explain the play in the cam gear. Look at the video..

Great and powerful happy happy joy joy stuff !!! Looks like I didn't have the new cam fully seated !! Took a couple light taps. I didn't try that at first because the old one came out so easily. I can not see now obvious damage anywhere and am going to set it aside for tonight before something bad happens...Thanks again guys.

Dropped the engine in toady and with a $35 carb....she runs great. Now to start another thread on the drive shaft problem.
