it can be moved slightly on the bolts that mount it ... but you will have to have the dash on the tach setting and adjust it to set the idle speed to the factory setting to get it to idle properly... the tps has a spring in it that gets weak with use and can cause the problem ... it can be adjusted to take up the slack from the spring being worn.. but the tps will need replaced eventually .... you can also adjust the throttle cable to take up the slack also.... the vibrations that an atv experience are usually worse than an automobile and will cause the tps sensor to become out of adjustmen easyer than 1 on a car... and will cause the problem of it dieing like you are having ...

hey quadnut ... just take a road trip and go riding while you in the area ...lol..

i have a 06 sportsman 500x2 efi that did the same thing several times .. an the dealer said that the throttle cable needed 2 be adjusted slightly to take care of it ... they said that it would do it more in cold weather and be more noticable in the cold ... they said i could adjust the cable a little or adjust the throttle position senser slightly 2 take care of it ... i dont remember what they said to set the idle at but you should be able to find that out from the dealer or from your owners manual or a service manual... i would also run some injector cleaner and some good hi octain fuel throught it ...

well it could be several problems from sitting.... i fuel can be bad .. but that wont cause it to smoke very much...,the seales on the valves can be cracked and worn ... the rings can be worn or stuck some what in the groves on the piston from sitting causeing the smoking... if the air filter is very dirty it can cause it to suck oil from the crank case an smoke also... i wouls check the easy things to fix first then go from there ...

O wow ... another hoosier rider ...lol.. welcome to QC... im down the road an across the woods a few miles...lol.. but if ya wana join us on a weekend ride we are in the terre haute area ...

i think they are the same ... not shure if they ever changed them ... i looked in some parts manuals i have and they are the same from 76 up to 83 .. but cant find any info b4 76 .. not shure on the lever ... but if ya look on ebay im shure you can find 1 there ...

itp makes them with stock back spacing ... just gotta look for them...

well glad 2 hear ya got out on u quad for a few ...lol.. ive put about 20+ miles on mine sence friday afternoon ...and plan on riding some more tomorrow (sunday)

hahaha there nut i have them spent already..lol.. and the tucker rocky dist. place is only about 3 hours from me ...lol.. thats prolly Y i got it first...lol

its hard 2 say... the bulbs are fairly cheap an i would try another set 2 see if thats the prob... an if it is then that an easy fix... if not then you will have to go through the steps of checking the light sockets with a test light an see what's up .. an then go from there an see what else ya can come up with..

well OX... i got part of my prizes 2day.. i got the gallon of tire sealer at about 1:45 ...

well i got my first part of the prizes today..... i got the gallon of tire sealer from quadboss ... ups delevered it about 1:45 this afternoon.. .. has any one got there stickers yet ?

so ox ya get any thing yet ?...lol... im still waiting on mine also...lol... hahaha ... its only been 4 days ...lol

lol... yup its there on mine 2 ...lol... never really payd much attention 2 it b4 ...lol.. but its there

congrats there OX... an i wish all the steelers were like that here ,,,most are greedy an turn there nose up at ya if you dont look like you have money ...or if ya dont spend a bunch there ...

hey mario the rack my boy was talking about is a steel rack ... ill see if i can find it in a catalogue i have .. i used 2 have 1 on 1 of my 400ex's and it worked great... ill see if i can find a part # 4 ya also...

no prob man.... glad it worked out for ya .... as for your reverse issue ... is the rev limiter causing it 2 do that in reverse?

i would check the carb first and make shure thats not the prob... and then start checking other things if it till does it ... the spark plug could also cause thoes symptoms ..

good morning all here at QC ... its about 5:00 am here in indiana again...

lol... thats funny guys ... i did drink alot of coffee the last few weeks an about a pack of smokes a nite ....lol... but not any ware that much...lol... and thanks for ommenting on my posts ... ill keep digging from time to time ...

thoes can be hard 2 put on... you might have to get a longer bolt and tighten it very slowly to get it to go down to the splines... but you have to be very careful doing it or you can damage the shaft an threds an the splines ... use some lube also...

yes they changed them to 14 front when the added reverse... i have had both and have worked on countless numbers of both.... they also changed the splines on he output shaft ... and the older sprockets wont fit the newer 1's

thanks every one ... it was a blast doing it ... but staying in the lead the last few days was a chore ..i had alot of problems with my internet ... weather and squirls chewing the lines made it rough ... then last night rite after 12:00 some 1 shot or blew up some line junction box nearme and i have been off line sence about 12:38 ... i had fun digging up old posts .. and the post miner is still going to be digging up stuff when i can... again guys ... it was a fun contest .. and i had fun and made alot of new frends on here because of this contest .... enjoy the new year ... and ill see you on the posts ... brought to you by the postminer... :-)....lol...
