Title: For those of you who run without cam-belt covers-
Post by: Radar on May 01, 2011, 08:15:14 AM
Howdy folks,

I have to admit I really like the look of the bikes without covers, but I have to wonder if there is any concern or experience with premature belt or pulley wear. Although I assume the pulley's bearings are sealed units...

I guess it seems to me that even small bits of debris would increase wear...

Just wondering...

Ive been working on my bike over the winter, and have never riden without the covers. That being said, I did notice that even with the covers on, I see a lot of grit and grim in the belt areas. So if I were to make an analogy, I would say it might be better to run without the covers. That way the dirt will not float around behind the cover. Personally, I'm too chicken shit to give it a try, so I will probably buy the Rizoma covers.

Now, that's an interesting observation!

I hope others will share their knowledge/experience.

Thanks,

Got Speedymoto belt covers on and never had an issue.  The belt covers block crap thrown up by my tires and the actual covers themselves keep out all the big stuff.  Every now and then I run compressed air around it to get out any dust/small particles that might be in there.  I don't worry about anything getting in there and the look is super nice!

You're going to get a mix of opinions...

I've run without belt covers for years.

Yes, there is a risk.  I've had belt heads since around 1990 and never had a problem tho.

But that rock/screw/turd could just as easily bounce up and go into your helmet or neck and crush your trachea.

Think about how many times debris hits your legs -- often?  if so, you probably are riding in crappy areas. 

I rarely have stuff hitting me, that means about the same is hitting my engine.

IF you are still nervous, some folks have cut out the centre and put in lucite, but it dirties pretty quickly.

running the stock covers can be worse than no covers. the backing covers become very brittle from the many heat cycles. thus leading to large pieces of plastic getting jostled around. my inner backing covers broke when removing them and i was being gentle cause i wanted to save'em.

this i coming for somebody who doesn't have inner or outer covers.

i think you'll be fine without them. your belts stay cooler without the covers anyway.

I've been running them w/o covers since the late winter.  Although they look kinda cool, I've had some riders ask me if I forgot to put the covers back on.  This makes me think that it just looks incomplete.   If you look at it close enough, it does look like something belongs their, but isn't.

I cut my stock covers and run with the pulleys coverer. When I get three hundred dollars to throw toward covers I will get the speedy moto. I have concerns but not enough to buy new covers. That being said I was talking to a Harley rider who replaced his belt drive with chain because he picked up a rock and it shredded his drive belt. So ---------- I don't know.

the drive belt is lower and in a far more exposed location.

I've been running without covers for over 2 years now.  My friends keep telling me how it will get screwed up and I keep telling them I am going to put the covers back on...  I know the risks and am prepared to deal with any unfortunate outcome.  I don't think they are going back on any time soon.

I've been running with my inspection covers off for about 6 months now (changing the belts is on my list, ahem).  There's a lot of crap at the bottom.  And my backing covers have been toast for years - all cracked up.  I've always wondered if a piece will fall off into the belts...

On the other hand didn't a dude supposedly get his finger between the belt & roller a few months back?  The DP & Howie know the thread I'm referencing.

ive ridden for a long without belt covers even crashed the bike without covers on, the only reason i put them back on is the fact that rain makes them rust and the rust make them squeaky and its an annoying sound to hear.

The belts I bought from CA Cycleworks came with a note that saying not to expose them to sunlight.  Now, how long before sun exposure deteriorates belts, who knows?  But for my money, keep out the weather, the dirt, and the sun with the belt covers.

I think the damage from sunlight may be the biggest unknown.  The sun degrades rubber and plastic in much less obvious ways than physical issues from rocks and other debris.  

Our Founder/Painter could probably illustrate this better than me but from what I've learned of modern automotive finishes the clear coat is there to provide UV protection and gloss for the color coat.  This is why paints are different for interior and exterior applications.  Interior paints don't need the UV protection.  

I would really like to run no belts, but the sun damage makes me nervous.

This isn't an issue unless you leave your bike outside when you're not riding.  Intermittent exposure to sun (UV) won't affect it.

He has had these Speedymoto "covers" on his bike for at least 2 years with no problems at all

I chose the cheap route and cut the stockers.  So far so good!!

going on 5 years and 30k+ mi on mine w/o covers.

that's 4 New England winters, rain, snow & salt, UV exposure during work day, trackdays, dirt trail riding, traffic, etc...

No issues, no squeaks, no leaks. belts are changed every 3-6k mi.

the only thing I would be concerned about is the cover holding something that bounces up, rather than letting it drop off.

if a pebble hits a belt, it will most likely be zinged right away.  no cover, it goes back where it came from, but with an open cover like that it is more likely to be "captured" by the cover and then bounce around inside.

I was actually thinking about notching the bottom just for that reason.  Only concern is if it would make the cover to flimsy.  Then again it's not a load bearing part so I am thinking it should be ok.

exactly.  not load bearing and not structural in any way.

someone else did the same mod but put a lucite window there a while back.  also, another fellow used a mesh grating which looked nice.

I like the look of the lucite but I have heard that it gets ugly pretty quick and not really wanting the mesh look.  As open as it is, it still kinda blocks the full view. Maybe a more open pattern would work. I think the notches in the bottom are what i will be doing in the future
