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!

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.

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

Did you get it running?

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. 😜

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.

      Hello everyone, I just picked up an 02 LT-F250F the other day and have been in the process of tearing it down to fix some stuff- one of which was the cylinder base gasket leaking like a sieve. Well, I know why that is now, and I also discovered that someone had been in there before. I didn't take pictures, but it looks like it was probably run low on oil at some point, the cam journals and the "bearings" (for lack of a better term) in the head and the valve cover are totally wiped out, very deep grooves.  From what I know it's very difficult to repair aluminum in this way, so I'm trying to figure out where to go next.
       
      1. Have someone grind down the head and valve cover and fit actual bearings in since the aluminum is screwed, and have the cam ground down to match.  I have no idea what this would cost.
      2. Buy a replacement head+cam+valve cover.
       
      #1 I was hoping someone might have some advice on, but #2 seems like it'll (probably) be the more cost effective option.  However I'm running into some difficulty, it seems like the 2001 and 2002 models specifically use a different head part number,  11100-19B10, instead of  11100-19B01 like for all earlier models.  What exactly is the difference between them? There are obviously far more of the earlier heads because it ran for over 10 years.  Are they actually interchangeable? I've also noticed there are heads from the LT250EF that has 4 valve heads but also otherwise look identical.  Would those work as well possibly?  I'd like to not have to drop $500 on machine work or new heads on a $1300 quad that I'm already putting a bunch of new parts on.  Oh, and it has a new piston and the cylinder itself looks pretty good too, as I said someone was in here before me.
       
      Any help or advice would be greatly appreciated. I'll post pics of the carnage tomorrow.

      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.

      Hello,
      I was able to repair most of the little problems on my 2006 BRUIN. I still have little things to do...
      I changed the Hazard light Switch because it was not locking when pushed and now it is not working at all. When I connect it (not sure of the wiring -4 wires but a lot of connection possible on this HELLA 3916-01 switch-) the flashing lights button (on the handlebar) is acting like the Hazard light switch.

      First issue was fuel pump wont start once ignition has been turned on. Replaced the pump as I had one on hand, than noticed no power so replaced the fuel pump relay as that was were i traced the power to. Still nothing so further inspection looks like signal is coming from the PCM (FLR B20) but not switching the the brown wire to the fuel pump. Ive checked the operation of the bank angle sensor and it appears operational. Fuses and wiring all appear OK. The engine stop relay also tests OK. Ive been through the repair manual and diagrams but to no avail. Fully stumped, any tips would be helpful. Thanks

      Hey all back again with my 1989 moto 4 250.
      After putting a new carb on it it's really sputtery, it has new gas and I'm wondering what to tune on the carb to make it idle better. I've attached a video to describe the issue more. The bike is still work in progress but I think the video gets the point across. Thanks!
