Not good............... :-X

Don't tell me you were cleaning your bike with the engine running? Did you not see the post a couple of months past where the guy was cleaning his chain while the bike was in gear? Bad things happen when you put body parts near moving mechanical componants.
Nope.
Towel was on the tank, slipped off while bike was on.
Somehow the belt caught it on the way down.
Sucks.
:-X
Did it jump time? If not you can just remove the belt & set it back again. Crazy things happen.
Sorry, but I laughed.
I put the bike in gear with engine off and rolled it to spit it out.
But I think it threw a valve. There's a knocking sound when it cranks.
Yep, sh*t happens. Too bad it happened to my Lil Monster. :P
Good thing it didn't happen to the 4 valvers.
Well maybe with some luck its only one valve or as few as possible and not the guides. :-\
ugh, that sucks. hope you will manage to bring it back to life without a big hit on the wallet...
there is another thread to link to when someone asks about open belt covers...

hope not, that bike would be in the future!
Sorry that happened to you. I hope it isn't what you think it is. You should pull the head and inspect it before you run it anymore.
Have you ever wanted a little more power? Maybe this could be an opportunity to do a top-end upgrade. I'm not sure what there is for 750's. I'm sure there are probably higher compression pistons. Maybe you could fit newer style heads. Do 696, 796, or 800 heads fit on a 750?

So for $670 in parts you could possibly have a new and improved bike. You should call Duck-Stew to get an idea of what kind of difference you could expect.
So for the 'sexiness' of naked belts you got a towel in the cogs. Nice.
It could have happened on the road, a pebble into the belts etc.
I've never understood open belts, open clutches etc, especially when you see rusted clutch plates and things like this. I don't drive around with the hood off the truck, put the covers back on if its a road bike.
Unreal.

to each their own
some people don't understand motorcycle riding to begin with
I've had open belt covers for the past 5 years and about 20k miles with no issues
like everything in life, it's a matter of balancing risk with desire and accepting the consequences of one's actions if the worst case scenario arises
Full belt covers or nothing at all.
If that half-cover hadn't been on, that rag would have just passed thru.
I've run without covers for years. Never had a problem. But I also don't clean my bike when its running....
someone please show me ONE incident where you were riding on the road and something got caught in the belts.
ive never heard of that. ever.
just a few hundred miles shy of 30k and never had any issues. that includes me tossing a bike into a dirt field.

the service writer at my shop has what appears to be 1/4 of a toothpick worth of splintered wood on his desk that got caught between a belt and pulley while riding that caused it to jump timing.

Magnus, what was the damage to your moto?
I so badly want to run open belts but if anything happened my wife would kill me for taking the chance. She hates that I got it and refuses to get on the death trap as she calls it.

It wasn't that bad considering what could have happened, just two bent exhaust valves on the forward cylinder. No valve guide damage and no piston damage.

Did not want to screw with you He Man, just remembered that thread. Another funny thing is that I am always on the fence with this and there is a good chance I will run them open next riding season... I am actually more concerned that some funny guy puts in there something while it is parked.

2 exhaust valves on the forward cylinder? on a 2valver?

Nope. Water cooled 4 valver.

Your thumb will thank you not to do this. Ask me how I know. ;D
This is no good. I heard of a sport classic guy have this happen while wiping his bike down during warm up. Short of getting my finger drug though, I wouldn't go back to covered belts.
Good luck to you sir. [beer]

Travman, I'm not sure if I should curse you or thank you. I avoided responding to this to allow some time for soaking in any plausible options.
Now it seems I can't get past at least ordering the 620 heads. :P
I always try to use any bike misfortune as an excuse to do something good. For example, a ding in the tank = the paint job I've always wanted. It helps you get what you really want and to ease the pain of doing something stupid. You can always tell yourself that you were going to do this anyways, the rag in the belts incident just was coincidence.
Seriously, call Stuart and talk with him about adding the higher compression pistons or possibly just the 620 heads. He'll be able to tell you what to expect and whether or not it will be worth it to you.
I have a spare head for a M750. PM sent, give me a call!

woohoo!!
If you're like me, you are more of a threat to those open belts than road debris.
My gloved finger got caught in the vert cyl belt (M900). New gloves that are a tad too long.My finger was ok. I had grabbed the bottom of the tank to back up in the grass in my front yard when it got caught and died. Wouldn't re-start. One valve got bent. The valve guides were ok.
Yes, I still run no belt covers
i had my jeans get caught up in open clutch while riding... i felt a tug on leg and it just tore a big chunk right off.
