Welciome to the forums.
That guy is old and grey by now.
What's it doing?

 

Haha well, it's making a terrible sound when your getting on the throttle.. at idle it's not so bad, but i took at apart after seeing this post and saw that my fixed drive face was stripped at the the point were it meets the shaft. I was riding it and it just started making a sort of squeak.. then it just got louder and louder. I tore the engine apart and saw that my cylinder and piston are scored really badly. I'm to blame i feel, when i got it about 3 weeks ago it had sat for around 3 years. I should have torn it apart to make sure everything was tightened down. the crankcase was full to the top with gas as well.. it has some problems.. any info you got is gladly appreciated..

 

116 miles from me LOL. Which may be the good news.
Is there any up and down play in the rod? It will wiggle side to side slightly.
When you spin the crank over now, does it spin freely?

 

yes my rod has side to side play.. and the crank spins freely but has the magnets so of course it's gonna have them spots where it's slightly harder to trun. what could the side to side play be?

 

Like I mentioned, it will wiggle side to side some.
If it wiggles too much, it will have up/down play. This is what you need to figure out.
75% chance all is fine.

 

Exactly same problem here with my LT80..
Out of the service shop. Rode it for a total of 5-6 hours and suddenly last week heard that sound of the drive face hitting the case.. Good thing i wasnt far from home and only moved it for about 1/10 mile.

And guess what! Yes.. That washer behind the fixed drive face is missing!!

Now should i replace it or its not a bad damage? Hard to find new parts here. cost for this is 130USD + shipping but will have to wait at least 2-3 weeks to get it and summer season almost over here.

 

Welcome to the forums.
What year LT80?
87/88 models used a long spacer and no washer.
Whether it's bad or not depends on the splines. If the parts spins on the crankshaft, no good. If the splines still hold onto the the crankshaft, it's good.
If you measure the spacer I can tell you if you need that washer.

 

its a 1998 Lt80! I hope its that missing washer causing all the trouble

spacer is 35mm or 1.38inches long

 

I think i ll need a lil more help here!

The key that goes in the crankshaft looks worn! Is it possible that this is the cause of the fixed drive face to become loose? Should i also replace that key?

 

Your key will be OK.
Pull the starter gear off, take the key out and file the key and keyway smooth. Turn it around and install it.
Yor roller plate I'm sure is bad.
Why they loosen:: missing washer, spring washer upside down, nut wasn't tightened properly.
I gotta measure the spacer.
