My new 800 was in the shop all last week mechanic didn;t know what was wrong with it it was missing at wot finely the polaris tech called him back he told the tech what it was doing tech told him that some 800's run better than others and that he needed to put heavier weights in the clutch. picked it up friday I rode it at the shop and it seemed fine pulled front wheels up really easy I thought it was fixed. I didn't get to ride sat had honey do's So I got up this moring and went riding. The first time I got on it from a dead stop it took off good but it did miss 1 time i;ve been riding a little all day and the more I ride the more it misses it only has 4 hours on it do yall think it,s slipping the belt or is something else wrong I do know this it don't want to wheele anymore and it,s missing at w.o.t Thanks for the help
p.s tech said it was hitting the rev limiter does anyone know at what r.p.m the rev limiter kicks in

 

Roughrider, I'm not a Polaris tech but I have a mechanical background and will throw in a suggestion. I do know that if the throttle cable has too much free-play/slack in it, the machine will backfire/miss when accelerating. Apparently it has something to do with throwing off the signal between the throttle position sensor(TPS) and the (ECU) electronic control unit/computer. My dealer told me this when I bought my machine and showed me how to adjust it if needed. It is a simple adjustment and the adjuster is in the throttle cable up near the throttle control. The best I recall he said there should be 1/16" free-play in the throttle lever maximum. If your throttle lever has to be pushed more than this before resistance is felt this might be your problem. This should have been checked during the Pre-delivery set-up at the dealership. If this doesn't cure it, have them run the diagnostics on it. If they can't do this then find a dealer who can. If the mechanic couldn't figure out the problem in a week, it's doubtful he'll ever figure it out. There are some super great people on this forum who will help you if they can. I'm sure you'll hear from some of them if this doesn't cure the problem. Best of luck.

 

Fireslayer, Thanks for the help, I did adjust the free play in the cable with no luck I rode it awhile ago and noticest something when it,s missing my R.P.M,s are around 6400 to 6500. I can back off the throttle and let it have it,s head nail it again and R.P.M,s are around 6100 to 6250 with no missing what so ever it seems like the clutch is not shifting out just right or the belts slipping you can be going 10 to 20 M.P H and nail it and it misses really bad get it rolling 40 to 50 M.P.H and nail it and it never misses again. I may have to find a new dealer I do know 1 thing Iam ready to get this thing fixed im afraid im going to have a stroke. When you spend that much money for a 4-wheeler you expect it to run right it,s brand new[img]i/expressions/face-icon-small-mad.gif[/img]

 

Hang in there Roughrider, Some of these guys are a lot more knowledgable than I am and can help you out with other suggestions. Just keep reposting every day or so if you don't get a response. I'm sure someone can get you on the right track.

 

what do you mean by missing? like reving the engine to high and bouncing off the rev limter?

 

i think hes saying more of a stumble when he punches it

 

I think it is hitting the rev limiter has anyone ever heard of this
Thanks to all for the help

 

does it act just like your hitting it in reverse w/out pushing the override button?

 

I found out what the problem was today the mech said that a sealed bearing or bushing can't remeber witch was slinging grease on the belt and sheves inside the belt cover should be fixed Friday I hope this does the trick will post when I find out if he knows what he,s talkin about

 

so basicly it was hitting the rev limiter from the belt slippage by the sounds.
