Flywheel JAMMED

PostAuthor: k.huang402 » Mon Nov 05, 2018 6:45 pm

Hey everyone,

This is my first post so please bare with me.

I have an 83 xv920 and I've been trying to get this bike to turn over. My first thought was the common starter system to which I replaced the starter motor and #2 idler gear. When trying to run it with a fully charged battery, I hear the dreaded grinding noise which sounds like it's from the #2 idler gear and the flywheel. I check to make sure the starter motor was turning clockwise as well but to omit all possibilities and it turns correctly. The flywheel is in pretty good condition and not overly worn down as well.

I then tried to turn the fly wheel clockwise (in Neutral) with a ratchet and it does not seem to turn. I am assuming this is the cause of my problem but do not know what to do from here. I am up for suggestions. Thank you.

UPDATE****
Since I couldn't turn the flywheel clockwise, I turned it counter clockwise with hopes that the pistons were not seized. I was able to give it about a half turn before I wasn't able to turn it anymore. I sprayed some WD-40 in both of the cylinders and did a quarter turn and sprayed some more WD-40. I left it at a quarter turn where it felt easiest to turn hoping the starter system will catch the flywheel at its easiest position. I tried to fire it up and now the #2 idler gear engages with the flywheel and cranks but does not start.

attack one issue at a time.

so does the starter turn it over ok? [disregarding the sound- it will always be 'vocal']

Yes, it does turn over for a few seconds and then it sounds like the #2 ilder gear disengages and goes back to grinding.

I am confused. You said you could not turn the engine over clockwise using the crankshaft nut and then you said it turns over a few times with the starter. Which is it?? If you cannot turn the engine over with a wrench something is broken inside the engine... You need to find out what. I assume you had the plugs removed when you were trying to turn the engine with a wrench. Correct??

ditto.
pull the plugs [ground them to cylinders so you don't over-tax the ignition, and to can see if they spark]
crank it over for 15 to 30 seconds - to see 1) spark, 2) if engine turns consistently.

be advised that Gen-I starter system is known for sounding like it has a bucket-o-rocks in there.
it can be disconcerting, but is "normal".

if the idler gear disengages the engine will not turn over. is that what is happening?

I got the flywheel to spin without the plugs in it and we do have spark. Also it does seem like the idler gear is disengaging prematurely. Here’s a video of the issue.

That's pretty normal for the early model Virago's with the Bendix style starter. A 4 brush starter will help with this as well. It's usually due to a worn #2 idler gear and / or worn teeth on the flywheel. Noticed you pumped the throttle.... That doesn't do anything since there is no accelerator pump. Always try and start a motorcycle with the throttle closed.... If you feel you need more fuel in the mix, add some choke...

Thank you. I finally got it to start. I appreciate the advice.
