My Quadmaster runs great on level ground and downhill. The other day we were going up a slight upgrade and it backfired and lost power going uphill. My neighbor says it needs a new spark plug. thoughts? I bought a new spark plug, however, I cant find where the spark plug is. Obviously Im not a mechanic! I looked everywhere without taking parts off. Can someone please tell me where the spark plug is? Very much appreciated!

Hello everyone !! Looking for some help !! Im wanting to check my stator and pick up coil with a ohm meter and cant seem to find a guide that tells me what to read and what my reading should be !! Any help would be great !! THANKS IN ADVANCE !!

I'm working on my brothers' 2002 Suzuki Vinson 500 . It sat for a few years before I got into it. I'm concentrating on the carb - I replaced orings, needle, etc. and soaked jets, bowl and anything that I could get off the carb that the solution wouldn't eat. I also removed the tank and flushed it with hot water - it's clean. The gas cap innards rusted away and the tank had a lot of rust and water in it before I cleaned it. I replaced the gas cap and installed a new fuel valve because the screens were broken in the old one. The bike will run but spits and sputters and backfires. If you "open it up" it falls on its face and stalls - but starts right up. Here is a link to an exploded view of the carb: Ohio Honda Yamaha Motorcycle ATV Dealer - J & J Motors - Kawasaki Suzuki Scooter Utility vehicle, parts, accessories, apparel Can anyone point me in the direction of the problem? It may still be a "clean carb parts issue" . My problem is that the parts list doesn't identify the parts to a degree that I understand. If you said" look at the pilot jet", I'm not sure which jet that would be....See what I mean? It'll run very good if I remove the air filter and cover the opening with my hand and part my fingers a little for the air to get in. Any help is greatly appreciated. Thanks in advance, Jim

My four wheeler when i first got it seemed like it was very slow when i first got it and it had no throttle response so i replaced the belt and cleaned all of the rollers thinking that would solve the problem from what i read on the forums. well it turned out that it wasnt. so i went to the next thing i took out the injector to check it out and i seen that there was a tiny bit of debree in it so i cleaned it and it seemed to improve a little bit. but still did not solve the problem. i later found out how to find the trouble codes out from the lcd screen using a paper clip on the diagnostic port and it showed the code which stood for no codes C00. i also forgot to mention that the throttle position censor is working perfect. before i started all of this the four wheeler ran just not to its potential. after my friend and i did the trouble code test the bike wouldnt even start anymore and the injector would spray for a few seconds for the start up then it stops and the fuel injection light comes on and blinks. the four wheeler wouldnt start anymore. i took it over to the local shop and they hooked it up to the computer to see if there was any codes and it still showed it was free of codes. they hooked it up to the fuel pressure gauge and we found that it was making 22 pounds and it should be making around 43. i then bought a new fuel pump and put it in. it now starts and runs for a few seconds and then it stalls out and the fuel injection light comes on again. which then leads me to think it is the ecu now but i want to be sure before i invest around $500 more into it. any opinions on whether or not anyone thinks this is the problem or if they have had a similar problem before would be really appreciated. sorry for writing a novel and not spelling very well. also i forgot to put the year in the title it is a 2007

I just got this bike and not getting any spark I know nothing about it so before I spend any money on it I like to see if it fires dose it have to have a battery to complete a circut and spark cause it dosent have one

I have a '94 160cc Quadrunner. Old, but has been working great. Suddenly one day when I tried to restart it all I hear is a loud and rapid clicking from the solenoid up by the battery. I bought a new solenoid online but that doesn't fix it. I took off the starter and it spins fine on the bench. I reinstalled the starter and then went directly from the battery to the pole of the solenoid that goes to the starter and it turned over so I think the battery is ok. It was brand new last November. I'm thinking it must be the solenoid. Seems unlikely that a brand new solenoid from Bikebandit.com would be defective but is that what the problem is? If so, I can send it back. Is there a way to test it with a multimeter to see if I get 12 volts? Could it be something else? Sure would appreciate any help. Deke

the king quad had sit for about 1 1/2 years. So I rebuilt the carb and now it will not start. Any help will be greatly appreciated.

ok my friend keeps his quad at my house since he lives in town all i have to do is keep it maintained. so the other day we were riding and noticed it was getting harder to shift. now stupid question, i know where you put the motor oil in and thats good to go but is there trany fluid or any thing like that? if not where would i start in figuring out why its hard to shift. another thing is it wont idle right, tried adjusting the idle adjustment on it but just wont do it. think i need to get it apart and clean it up. also is there any thing else i need to do to keep this thing up and running?

I need to know what I have and what tire really go on it, Mine has 24x11x10 on the back and 22x8x10 on the front and I need new tire but I don't think are the right size. Also I can't find the model number listed but it looks like a 250 quadrunner 2wd and I think it is a 1987 maybe, can anyone help me, also I it has a rich running sound and I put a carb diap in it and cleaned the carb. is there a jet needing replaced?

Hello Just signed up, as I've had a recurring problem, and need some help. To start the bike I have to put the choke on all the way and 4 squeezes on the gas, Then as I push the start, I slow squeeze the throttle about half way for it to catch....If I miss it, then it will take 5 mins of slowly finding the sweetspot on the choke in unison with some throttle squeezes. Then I have to to hold the throttle to keep the bike going, using the choke will stall it out. after about 3 mins of holding the throttle, I then can let it go, and it idles fine, and runs fine. If it sits for a few hours it's only slightly hard to start, but a few days of sitting, and it's a lot more work. Had the bike serviced they couldn't figure it out. They swapped peticock, plug, new gas, all new lines, new throttle, and cable. Said the carb was fine, and clean. New air filter, said fuel pump was fine, no leaks around carb boots, new battery, new rectifier. Ran some sea foam through it....Runs Great.....Just such a pain to start... Thanks

loud clicking, snapping noise under load when accelerating.

I went out to ride my quad today. When I started it up it ran for a minute, then died. Since then it will turn over but won't start. I've check the spark plug and get great fire. I have had this quad for about 6 months, and very new to breaking it down. But need help. Thanks

I have a 2007 Suzuki Vinson 500, Semi-Auto, 4X4. I was riding it last winter in a couple inches of snow and a little ice. It ran perfect for a few hours and then starting a slight backfire for about 15 minutes I noticed the over heating light was on so I got ready to shut it off and before I could it shut off by itself. I let it cool down for about 3 hours then i went to restart it I got nothing, the display screen was completely blank and only the back light was on. I then checked the fuses and noticed the ignition fuse was blown I believe it was a 10 or 15 amp fuse so I replaced it then started it up it ran for about 5 minutes then cut off and blew the fuse again. I tried several times throughout the day giving it about an hour in between each start. After about 5 trys i put a 30 amp fuse in and still did the same thing. I let it sit for a couple days to dry everything out and tried again same thing blew the ignition fuse after about 5 minutes. So I then took apart all the electrical connections cleaned them and dried them and then once again tried and blew the ignition fuse. I do not know what could be causing this and havent been able to find any others with this issue. If anyone could be of any help I would greatly appreciate it. Thanks Donald Roberts

Hello to the group just found this site and as an new owner am looking for the owners manual for my machine I found the service manual can someone please point me to a location for the owners manual. Thanks

Hey, does anyone have a pdf for service manual on an LT230? Having some issues.

My 2000 suzuki quadrunner 500 has a leak at the rear of the crank case cover. You can see the oil very lightly spitting out when you look at it from the rear. I first found the bolt loose and I tighten it just lightly (I think they say 8 ft pounds). That stop part of the leak, but you can still see it coming out at the gasket between the two halves. I am mechanically inclined, but was just wondering if there are any surprises I might be aware of when I take off the pull cord assembly, shifter ext. Do you think there could be any other issues when I get it apart?? Doesn't appear to be any crack and I can see it just slightly spay out right in one little spot where the bolt is. Any help is appreciated.
