1988 Suzuki LT 250 S quadrunner wont start.

Recommended Posts

Hey folks, brand newbie here.  I just bought a pair of near identical quads, the difference is that 1 is a 1988 and 1 is a 1989.  The 89 runs and the 88 does not.  Turn the key up 1 click,  no neutral or reverse lights.  2 clicks, still no neutral or reverse lights but the speedometer lights come on.  Switch to run and hit the start button and nothing.  Since I have 2 of the same and 1 runs I'm ok switching out parts.....but where do I start?  Any help is appreciated.  Thanks!

Welcome to QUADCRAZY, I moved your topic into the Suzuki forum. I would swap the ignition switch from the 89 and see if it starts.

Hey Ajmboy, thanks for the suggestion.  Here is how I got this one started.  Going through the factory Suzuki manual (which I downloaded from Quadcrazy...THANK YOU GUYS!!!) I ran a diagnostic and found out the reverse switch was bad.  I swapped In a reverse switch and got back my neutral and reverse lights.  Plus, I now have ignition.  The neutral and reverse switches are tied in to each other on this bike so if 1 is bad, neither light works.  Both switches need to work to get push button ignition.

Having exactly the same problem. Need the factory manual to work out what's going on, but need 10 posts...

Not sure, but I think the switch and the pull are independant systems.  

Did you get it going??

My buddy did the same thing.  Got two, got another one for parts, needed up getting another one and now we’re trying to get three running. One for his wife, one for him, and one for me.  If we can figure out the whole not wanting to idle and smoking real bad things. 😜

I also need more posts and a manual. 

The electric start spins but won’t engage and the manual pull start is very hard to pull, it seems like more than compression but I am new to these quads

I had a lot of trouble getting a 2001 LT F250F running. It seems that they are sensitive to the gas around here so using ethanol free gas is a start also, the carb must be shiny clean and make sure that you check and adjust the valve clearance

Nope, the decomp lever would only be required when pull starting - the electric starting issue may be just that your battery is low. Need to do a load test on it.

I don’t think The battery was an issue because I was jumping it.  Starter spins well but doesn’t seem to engage. I just got two of these bikes, one two wheel drive and one four wheel drive, both are in rough shape with the wiring home remedied.

To follow up on my previous post, I am new to quads so all assistance is much appreciated. I hate to see old vehicles discarded instead of repaired

Sounds to me like you have a starter clutch that has failed. To repair this requires removal of the ignition side case cover and pulling the flywheel off which needs a special tool to do so.

There is a one-way bearing likely attached to the back side of the flywheel. If this has failed there may be other parts involved that are worn. Not the easiest of jobs but it's usually possible to do without engine removal.

I've done this fix on a newer 300 Suzuki quad but I believe the older ones also used this style of starter system. Hope this helps.

It's just called a flywheel puller - they're different sizes and you need one that's specific for your motor.

They shouldn't be that expensive to buy, or else you can take it to your local shop that services these brands and get them to pull it for you.

      Installed new battery was told that’s what was wrong when hit start button I hear 1 click then nothing?  Can the battery just not have enough amps to crank the starter the first time ? I trickle charged it overnight thought it was enough!

      Does anybody out there have a link to the PDF manual download for a 1988 Suzuki Quadrunner LTD 4 x 4? If not does anybody have this on digital file they could possibly email to me or guide me in any direction to where I don't have to buy it? Thank you very much everybody in advance! Have a great day!

      Exploiting a loop hole in the law, turn 4 wheeler into rev trike
      for a long while I have been trying to get a real 4 wheeler street legal.
      the problem is with the state laws, if it has 4 wheels, its a car and has mega more rules.
      If it only has 3 wheels, its a trike and can be made from cobbled junk parts held together with duct tape and they will plate it
      I wonder if anyone would have insight on changing a 4 wheeler over to a single rear wheel?
      [ I can't afford some $40-60,000 canam or super bike modded into a car, rev trike kit ]
      I want something I can truly ride year round on and off road. Ive rode enough old Honda 3 wheelers that I know I do not want a traditional motorcycle trike. So the single wheel has to go out back.

      Heres my story. Kinda long. I guess I was a late bloomer when it comes to quads. I had never ridden a quad in my life. Rode Dirt Bikes as a kid growing up. Back in Oct of '06 I found a Mustang on craigslist. Took it for a test drive one morning before work. Fast car. 351 Cleveland. I had planned on meeting the guy again after work. For some strange reason thats still to this day beyond me, I stopped in Hillsboro MotoSports on the way home from work. I had 6 Grand on me. There was a left over '05 sitting by the front door. It was on sale for $4999. It was $5499 OTD. I didnt even look at anything else. I knew nothing about quads accept I thought it really looked coool and I had the money in my pocket to buy it. I was sitting on it when the salesman walked up and asked... "Can I help you?" Without hestitation I pulled 60 Ben Franklins outta my front pocket and said "I want this Quad. Load it up in my truck." It was just about dark by the time I drove away from the shop. BTW, I didnt bother to ask my ol lady if I could buy it. LOL. Anyway, I took it by the house and showed her. She was kinda stunned but not mad. We drove over to a friend of mines house and unloaded it. I took it to the field across the street from his house. HOLY CHIT!!!!! I was surprised by the power. I had it for about 2 weeks and took it to Sand Lake. I was there a few hours and rolled it on a banked turn at the top of the bowl right before you get to the one-ways. When it rolled, I flew off and landed on my belly. The quad came bouncing and landed on my back. For a month I couldnt even walk. I was scared of it. I considered trading it for a 250EX. Went back to the shop. The salesman said..."Dude!!! You dont want a 250EX!!! Trust me. Just get used to it" I still wasnt convinced. I put it on craigslist for $4000. Calls were coming in. I had a guy that wanted to come look at it that evening. I decided to take it for one last ride at Browns Camp before I sold it. I was still afraid of it. After about 5 minutes I started feeling comfortable on it again. I decided right then, I loved my Honda 450 and would learn how to ride it instead of selling it. That was late Nov of '06. Work was slow for a Painter in Oregon. My new job everyday? Going to Browns Camp and ridding my Quad. I bought my Girl Friend an '02 Blaster. I rode my 450 for 4-6 hours almost every single day for 3 months. And yes, I know my way around Browns Camp pretty well. LOL. In March I bought her an '06 TRX250EX (Thank God I didnt trade my 450 for one of those) LOL Since then, I have become totally addicted to quads. I love them. Couldnt imagine not owning at least one quad. Luckily I have two. My "07 was $6500 OTD in July of '07. Bought it for my Girlfriend. Traded in her 250 EX. A month later we broke up. So, I wound up with two Honda 450's.
