any issues or potential problems with running an 03 polaris 800 ves without the clutch?
Thanks
Thanks
Is it OK to run the motor without the primary?

No issues unless you want to see how many R's you can turn!
I think most manuals state to not even run the sled without the belt. The problem of running without the belt (ie no load) is that your engine could hit peak rpms very quickly with just a little bit of throttle. I am not sure, but I thought that the engines use the primary clutch as a sort of flywheel, smoothing out vibrations.
That is my thoughts anyways.
What is the reason for running without a clutch? What are you trying to do?
I think blipping the throttle without a clutch / belt would be bad. Just running the motor to bleed the oil system, or something like that, not so bad.

fine to run it...just use common sense
Always been told to never run it without one.
better to just not do it at all, might be ok idle for a few seconds,
but DO NOT touch the throttle cause the engine will rev up and when you let off the throttle there is no load to slow down the engine so you will be fueling for idle but the engine is running faster, cause the sled to lean out and go boom.

I wouldn't.....if you can even start it without the clutch. Try pulling it over, not easy!
You'll probably try to rip your fingers out trying, the clutch acts as a flywheel.
I tried doing a compression test on a 800 with no clutch, the recoil ripped out of my hands, fingers hurt for days.

I must be missing something.
The clutch does nothing but introduce more imbalance to the crank, unless you had the crank and clutch balanced and have it timed. (Which most people don't do) so running without the clutch isn't going to do anything in the balance area.
I agree you don't want to be running the throttle and definitely don't run the R's up.
As for recoil/flywheel affect. Possibly but I have never had an issue.
I have ran my Arctic Cat sleds without the clutch to check crank seals and such without any issues. And I don't believe any of the big four manufactures expect the clutch to balance the crank.
Might be wrong here, but never had a problem.

Adding the clutch does not add a imbalance, it actually smothes it out, it acts as a flywheel to keep the momentum of the rotating mass going.
The added wieght on the end of the crank also reduces harmonics, Cat even added wieght to there primary on the 900 twin to help this.
I have tried pulling over a poo 800 twin with no clutch, its not fun at all.
Try starting a lawnmower with no blade on it, if you do get it started watch it jump around all over the place
FAIRY TALES............................................. ..
It's O.K. as others have said, just don't over -R.P.M. it
To the rest of you guys with fairy tales of vibration.........
I've run several engines (especially 2001-2002 800 Twins) with the clutches removed to diagnose and / or isolate a problem, and the engines DON'T VIBRATE!! with the clutches removed, period.

Jumpin' around all over the place
Al,
Ran my lawnmower with and without the blade, can't seem to get it to "Jump around all over the place"
I must be doing something wrong.........................................

What kinda lawnmower?
It's GREEN
Well, it's green and it's kinda old and the decals are worn off, not sure if its a Lawn Boy or an Arctic Cat???????????????????
And it appears to have some sort of modification done to the exhaust pipe
Maybe I'll take some pics later and post 'em on HCS, AJ would appreciate those

Had a 2001 800 (bud's sled) with a mid-range mild vibration.
Removed the primary the vibration was still there
Checked the crank run-out and surprisingly it was less than .002"
Ended up being the 3 or 4 bolts on the lower half of the recoil housing cover snapped off in the case, the recoil cover partially cracked and "cocked" causing the oil pump / water pump drive to only partially engage.
Chewed up the end of the water pump / oil pump shaft
So, YES I did diagnose the problem with no clutch on to answer your ??
But we had to securely bolt the sled, skis, engine, handlebars and driver to the concrete floor in order to keep the sled from "dancing all around"
