Tighten chain on 49cc atv - Quad 47 cc / 49 cc Pocket Mini Bike Scooter Atv Pull Start

sometimes you have stretched the chain beyond the specs for the chain saw. you may need to buy a new one.

If you have replaced the spark plug then the possibilities are the ignition coil is weak or the starter mechanism is faulty.

Hi Matt only help I can give is look along top & bottom of chain for a tensioner it will be a round rubber wheel. If you cant find a tensioner it will more than likely you need to cut the chain down. If your not sure how to let me know & i'll let you know how. Also DO NOT USE IT while chain is loose as if you do & chain comes off you can crack engine case which then means a new engine

how do i tighten front chain on 1998 polaris magnum 4x4

replace the sparkplug

in order to tighten your chain you can take a link off which would involve using a grinder, if you dont have one than go to an atv store and ask them to do it. theres a clip on the chain which holds it togther, remove the clip without damaging it than just pop the link off. that will take the chain off. i dont know what type off atv you have so there are probably bolts that hold pull the back end to tighten the chain look for those and if you can find them than tighten them.

for your engine do an oil change and drain out the carborator. if you need more help let me know.

I had a few chain driven polaris atv's they tension when weight is on the quad, the rear arm pivots and applies tension to the chain , other then that there should just be guides for the chain. If the chain is still loose with operator weight the chain may have play in the pins and need replaced.

I have the same problem and it's wearing on my frame we tightened it and all it did was stiffen the suspension
