I havent had a lot of success with JB weld on exhaust , doesnt like the high heat, but it will hold for a while, if still having problems they make putty for exhaust, also doent hold up well, the constant jaring of the machine loosens it and it falls out. Not much help, but that is my expierience.

1988 Suzuki Quadrunner 250 intermittent spark

Tanks do get nasty, being plastic helps a lot, not rust ot corrosion, and they clean up very easily. Good job getting it going and painting the racks, coming along nicely. - Today

1988 Suzuki Quadrunner 250 intermittent spark
Uglyside38 replied to Uglyside38's topic in Suzuki ATV Forum
Hey! So, I got back on the project this week. I've started up a part time small engine repair gig and it's been keeping me busy! Anyhow, I got the ol girl running pretty good. I cleaned out the fuel tank and while doing so, realized that was 90% of my problem all along.🤦🏼♂️ Can't believe I overlooked that. Tank was FILTHY! Pretty much was mud at the bottom and once I got that flushed and added fresh gas, she fired right away. Now to buy some front tires and she'll be ready to have some fun and be put to work. Painting the racks and front bumper also. Will have them put back on next week. (Busy this weekend 🥵) - Yesterday

I ended up welding a bombardier 400exhahst onto it ... And then it still backfired , I discovered more holes up near the head, I'm going to use some high heat jb weld to patch them

Thank you for your insight. I will check on the oil in the sump when I get a chance.
-
The most common reason for that oil in the airbox, and especially if it starts doing it suddenly, is that the sump is full of fuel. A sump full of fuel would also cause the engine dieng once it starts to get hot. I'd suggest checking the oil level as the first thing. A lot of bikes also have restrictor valves or orifices in their breather hoses, and in some models if that restrictor blocks up it can cause problems like the oil in the airbox.

Hi guys. I have a problem where the quad will start and run well for about 5 minutes and then it dies. On inspection the airbox has oil in it (quite a lot). The oil is pumping through the cylinder head breather hose. This problem first happened suddenly. I have since done the top end including, piston, gaskets, rings and valves. I have also done the carb (not that I thought that this was the problem). The compression seems normal. The only thing that I can think of, is that I did not grind the valves well enough. Anyone experienced this? If so, how did you fix it? Any other thoughts?

2012 John Deere Gator 850i RSX Idle Problem
N00bie replied to N00bie's topic in John Deere UTV Forum
You can adjust the throttle in the throttle body but would have to set it to about 4,000 rpm to keep the motor running. Low idle is entirely different than erratic idle (up down, up down -> dead) -
Thank you!!
-
Thank you, I can't remember which year it is so I will have a look later today and find out.
-
Thanks, I will strip out the loom and check the wiring, it needs checking anyway!!

The throttle cable is sure to have some adjustment somewhere. Polaris bikes have a kill switch built into the throttle and if there is slack in the cable, such as you would get if the throttle stuck on and your thumb was off the pedal, then it kills the engine. If those get too much free play in the cable at idle they kill the engine. It wouldn't surprise me if JD did the same. Apart from that though, if the throttle is held too far open, by the cable or someone having adjusted some stop somewhere, then the idle control motor or valve can't compensate enough and keeps the idle speed wound right down to zilch as much as it can, and that sets off a cycle of compensations and counter compensations that often ends in an engine not idling. I don't have the book, but I'd bet it says to check those things, and do a standard sort of tune and inspection of hoses etc.

2012 John Deere Gator 850i RSX Idle Problem
N00bie replied to N00bie's topic in John Deere UTV Forum
Not much to the throttle body that you can access. There are only 2 little holes where are the good stuff is located that cannot be serviced. Just pulled out the entire throttle body and cleaned it (wasn't really dirty) but don't expect it to do much. -
2012 John Deere Gator 850i RSX Idle Problem
N00bie replied to N00bie's topic in John Deere UTV Forum
Nothing beats a cigarette, Wish I still smoked The 02 sensor was bad (threads were stripped and it fit loosely in the housing but wasn't the real problem. Can disconnect both 02 sensors and no change. Throttle cable not really adjustable and IAC is integral to the throttle body and not serviceable. -
I’m with @Mech check power at relay.

2012 John Deere Gator 850i RSX Idle Problem
quadmaniac replied to N00bie's topic in John Deere UTV Forum
With fuel injection, it’s like a car… I would take the throttle body off and inspect. Maybe get some throttle body cleaner and spray it first and see what that does. -
It's likely that the O2 sensor wasn't defective. It quite likely was just struggling to control the mixture within acceptable limits and so reported it as not working. That's quite common with O2 sensors. They are one of the most miss-diagnosed components. I'd be checking the throttle cable adjustment, the fuel flow and pressure, the IAC operation(might operate on 5volts so be careful), and the spark plug gap and condition.

You have power to the relay, so now you need to check the relay is getting power to activated it, and that it has an earth on it's activation windings. If that side of the relay is operating, you need to check whether the power is getting from the relay to the pump, and that the pump has an earth. If you tell us what year and model this is I'll try to check in a manual how the pump and relay are actually wired. It's possible that the pump, or the relay, are powered and then get switched by connecting an earth to one or both of them.

1993 Suzuki King Quad 300 bucks and farts like crazy
quadmaniac replied to hardcastle's topic in Suzuki ATV Forum
That's a good point that often goes underdiagnosed with older quads, especially if they are sitting around. flush teh tank and change the inline fuel filter. -

Ajmboy replied to N00bie's topic in John Deere UTV Forum
Do you have a smoke machine? If not, I would get a cheap one and search for vacuum leaks around the intake. I have one from amazon I use on my cars and stuff like this, works pretty good with baby oil. Amazon Link -

That is the problem with this machine. Everything is in the throttle body ($1,200+). Haven't found a vacuum leak. -
Did they ever get back you? Were you able to get it going?

Hello All· 0 replies
I just joined the Forum and this Club. I'm a retired Auto and RV Mechanic. I tinkered with Dirt Bikes in the past, but now have gotten the Quad Craze and so here I am. I hope to bring more to the table then questions, lol. I will gladly contribute were I can! I am looking for a project. I'm intrigued by the Suzuki King Quad 4x4 or a Bayou 300-400 4x4. Any thoughts or advice is greatly appreciated!! Thanks!
