I have a 2006 500 sportsman and there is no power to the ign switch. The guy I bought it from said that he put a new battery in it and accidently shorted it when he was tightening up the pos post. I thought there may be a fuse but cannot find it. The power wires going into the ecm have power but nothing coming out. Any ideas thanks

I have a 2005 Sportsman 500 HO that has begun sputtering at around 3500 rpm only. It sputters like a rev limiter at 3500 Accelerating or decellerating. I have a spare parts bike and have swapped both modules rebuilt the carb, changed the plug and run 10 gallons of fresh gas through it. Any ideas what might cause a mid rpm miss?

Well went to start my 570 today. And now I have a grind that occasionally happens. Has anyone else had this problem? Ive been looking at tearing the stator cover off and inspecting to see if it broke a tooth off of one of the gears in the starting system. Thanks

I’ve been having issues with my new to me ’88 250 4×4 popping out of high forward gear. I pulled out the gear box expecting the shift fork to be bent, but it looks fine as does the rest of the gear box. The only issue I found is some noisy bearings that I’ll replace.

Since the problem doesn’t appear to be in the gear box, the shifter and linkage adjustment are all that’s left. I noticed there are notches on the plate where the gear labels are. I’m wondering if the shift lever is supposed to have tension pushing it into the notch to help hold it in gear. I bought the machine last year, so I don’t know if it’s been altered over the years…

I have a 84 TRX 200 that I bounced a valve in. first thought it was because it ticked pretty good. after further investigation. bought a small boar camera from amazon for $12 and low and behold perfect valve crescent moon.

options I have: Low buck if possible

leave it and run it and hope it is ok. still runs decent just ticks

I have a spare almost complete motor. head that is on it the exhaust bolt is stripped out pretty bad. thinking about taking valves out of this head and putting into current head on bike. would need to get seal kit.

with this option what seals would I need to complete this?
top end kit,
valve guilds
what else

any other options out there?

spare motor was missing parts and not sure what else it is missing. head is already pulled off of spare motor. bike is currently in running status. not so much riding status though.

i have a dyno jet commander V and a auto tune I had it on my 1000 sportsman highlifter it worked very well you can adjust fuel ratios and it will keep the engine in that range I richened mine up to keep the exhaust from melting the plastic I had no plastic melt on the bike not to mention the throttle response was very impressive it can be used on the 1000 and 850 sportsman or scrambler
I sold the bike and bought a rzr (highlifter was to low geared for me and my use) it had only 100 miles on it when I took this off and sold the bike
part #19-019 for commander V
AT-200 AUTO TUNE
had over 700.00 in it when I bought it have all the paper work original boxes and ect. would take 300.00 for it thanks I forget to get on here so just call or text me 660 247 2005

Hey all,

I’ve got a buddy who is looking to buy a TRX400EX from his neighbor… it’s a 2007 and cosmetically in great shape.

So… it’s all sounding great, but then he tells us that the shifter is broken and needs to be welded. Over the phone, I’m thinking it’s just the lever.. easy to fix, just replace it. When I got there, I found the lever was already off the quad, and that the splined shaft was actually broken… sheared off where it necks down between the inside and outside splines. The seller (not too mechanically inclined) thought the end that was broken off could be welded back onto the shaft.

We verified that it seems to shift just fine by gripping what’s left of the spindle with vice grips, so hopefully all the damage is external and limited to the shaft end.

We called a local Honda dealer and they said the labor to replace the shift spindle would be about $900… part not included.

At this point, we’re evaluating whether to move forward with this or not. My buddy and I have both done engine work on bikes and cars, but not so far as cracking the case and having a go at the insides… mostly just top-end work and external maintenance/repairs.

Given time, is this something could be handled by non-pros like us? I’ve been looking over the service manual, but it’s not precisely clear how much disassembly needs to happen to get to this part. Pretty sure the engine needs to come out, but can that part of the case be split without removing the head?

Regardless… his neighbor seems motivated to sell. It’s just been parked in his garage for a number of years since it broke. I suggested to my buddy to offer him $1000 under going rate ($2200-2700 around here)… at that price, he could always just pay to have it fixed, though maybe for less that what a dealer would charge. If he decides to do the repair work himself, then he got a great quad at an amazing price.

Thoughts?

Is the line on the float bowl a vent or a drain? Also, which way does the check valve face? Thx

2007 TRX 500 FA cannot get any pressure to bleed front disc brakes?

I am working on replacing the springs/spacers in the clutch of a 2009 Grizzly 700. Is there a way to measure excess wear on the drive (V) belt?
