Engine seems to bind?

PostAuthor: eric1126 » Mon Sep 07, 2020 9:10 am

History, new battery, starter, coils, tcu, coil pickups, voltage reg, engine acts like it is binding as starter in engaged ?
Compression is good, and it is in the proper time, anyone have an issue like this? 1985 Virago 700. Even with spark plugs pulled out still doesn't turn over easily? Thank you in advance for all replies. :;: :thanks:

:huh?:
:ider:
correct valve lash?
full clutch adjustment?
then at least they could be eliminated as suspect.

loosen banjo-bolt to check upper-end oiling?

cam-chain tensioner / guide issue?

preventing start?, or does it start/run?

any possibility that new pick-ups rub?

Is this with the starter or by hand?

Thank you for answering.
New pickups not rubbing, also even with plugs out does not turn over freely as it should, it is in time and has proper compression. Does not start. It used to. And ran well for a 54 he cruiser. Valve lash checked ok
Would a tensioner cause this issue?

just "spit-ballin' here", to see if anything will stick ---
'in theory' it could - I think when really worn, they usually cause/allow upper-end noise

only other thing that comes to mind --- is battery fully charged? is the 'new' starter up to the job?

just guessing here at what happened...
she was running ok, but began having start issues, so you replaced the battery, starter, and reg/rec??
now new starter seems not to be turning it up-to-normal-start-speed??

am I close?

if yes, double check your cables, grounds & connections.
JMO: only thing that fits all s/s is new starter issue :con: but again, that's jmo
someone else may have a better idea.

If everything checks out with the motor as you've said, maybe binding within the starter motor itself? Even though it's new, could have been assembled carelessly - I'd try loosening the two long bolts that hold it together just slightly to see if anything changes. Or, remove the starter, disassemble it and check to make sure everything is OK inside.

Thanks for all the advice, Darryl called Yamaha and they are suggesting taking off timing chain tensioner and chain to see if it is in top end. If not then removing engine and dissembling, to see if anything has made its way into engine? Or gear fail/bearing? Sounds way too expensive to me. I may just bring them the title. Or search for a donor engine?

Thanks for all replies on this topic, just returned from retrieving bike. May be for sale. Harrison Tennessee.
Maybe the guy that suggested to change vx to xv wants to come down and look at it? Don't get me wrong I love the little bike just cannot figure it out. I cannot post pics here (or don't know how) however she is a clean garage kept machine.

try turning the engine with the bolt on the end of the crankshaft with the plugs out and see if it turns over smoothly.

Turns ok, by hand maybe a lower end issue? This thing is a mystery.
Re checked lash. Was tight on intake valves. Re set to 4 thousants . Exhaust was ok at 6

If it turns ok by hand, I second the defective starter theory (or bad starter connections).
The engine rotates clockwise. If you try to rotate it counter-clockwise, it will feel like it's binding.
If you loosened or removed the chain tensioners, you need to rewind them before re-installing them or you will cause damage.

Installed couple ground frame to battery. Seemed to help. It will spin over and backfire with the best of them now.
