I had a similar issue with my 1989 Suzuki king quad it would idle fine but soon as I gave it gas it would Bog down it turned out to be a bad rectifier

First you need to install a choke cable. The grinding noise sounds like a bad starter. You don’t have to apply the break to start the ATV. The motor is a air cool motor. 

I highly recommend them I have six of them and they’re constantly on trickle charge for three ATVs my car and my two generator

There were plenty of times when I got stuck in four-wheel-drive and then I shifted into differential lock low the machine just crawled right out it’s an amazing machine a lot of tork. 

I have a 1998 Suzuki King quad love it I had one major problem with it it was the rectifier I had to replace it other than that runs like a charm never sell it

Ok I had the same problem rebuilt the carburetor check the fuel pump put all kinds of fuel additives in there and I couldn’t fix it. I threw in the towel dropped it off add an ATV place they worked on it it turned out to be the rectifier it was an electrical problem they replaced it and it’s running like a charm. The rectifier  is located in the front of the bike under the handlebars behind those louver slats if you can get at it look at it look at the back of it see if there’s any damage mine had a bulge in it and it was cracked. 

I had the same problem it was the Rectifier it went bad

I had a similar problem I have a 1998 king quad the quad idol perfect as soon as I gave a little gas the quad with spuderd and it had no power took the carburetor off cleaned it put it back same problem. I checked the petcock and clean that too still had the same problem. I drop the machine off at ATV dealer and motorcycle dealer they found the problem the problem was electrical it was the rectifier I would’ve never found that problem out I would’ve bet my life that it was the carburetor or a fuel problem. 

The rectifier is in the front below the handlebars and it’s right behind the vent slats that are right under the handlebars on the right side you have to take the front rack off and loosen some of the bolts that hold the front fenders onto the ATV and also The knobs that are on the selectors levers reverse low high remove that panel to then you’ll be able to peel back plastic just enough to get at the rectifier. 

Well I found out what was wrong with my King quad I rebuilt the carburetor and it still had the same problem idle perfect but when gave it gas it had no power I threw in the towel brought it to the mechanic that works on ATVs and bikes. He found the problem it was an electrical problem he had to replace my rectifier ATV runs perfect now. 

I had a similar problem with my 1998 Suzuki King quad started right up idol perfect as soon as I gave it gas it was sputtering and backfire and no power rebuilt the carburetor and Thats right WTF. I threw in the towel gave it to this guy on Long Island and he found that my rectify it was bad. BAD RECTIFY !

How are you doing guys I just joined I have a 1998 Suzuki King quad I’m having problems with high RPMs the ATV idols perfectly but soon as a throttle up it doesn’t stall but it just bogs down it has no power any suggestions thanks
