I am looking to see why my 2005 Grizzly 660 won't crank. I have set the valves but suspect a loose timing chain.
When working to remove the valve cover I found a "cap tensioner case" - parts #25 - #299 on Babbitts site.
The cover seems to bridge the valve cover and the cylinder head. What the hell is it and what surprises will I find if I remove it?
Uncharted territory for me.
The thing sat since Christmas 2018 and while I decided whether to replace the starter (which I finally did today). I am not sure if I added fuel stabilizer or not but chances are good I did. I kept the one year-old battery well charged during the winter. It turns over well but won't start. I have a blue spark on a brand new plug. When I pour a bit of fuel down the cylinder, the engine starts and runs for a few seconds (once for as long as about 8 sections) and then dies. Even before adding fuel to the cylinder I noticed that the spark plug was wet with fuel.
The air filter looks a bit dirty so I removed it just to see if the engine would start better but it made no difference.
If the fuel did not contain stabilizer then the carb may be gummed up. I don't really want to remove the carb to do a thorough cleaning. Is there a product I can spray into the carb while the engine turns over that will clean the carb?
Any other suggestions?
I wanted to share an experience and a fix.
Headed out was following a pole line, was looking for a cross track that may take me to this speckle trout looking spot on a creek. All paths and semi paths... failed. Second objective was to reach a speckle trout lake that has been recently stocked... followed 1 trail to dead end, followed second trail to dead end.... while investigating options on foot and the quad idling it died.
It wouldn't start. eventually it did... and when it did … it was essentially a pinned idle. activating the throttle did seem to speed it up but it wouldn't knock out of the racing idle. couldn't put it in gear at that idle speed. got towed out.
when I first got the quad, I ran it off a trail and buried it pretty good in the soft snow... eventually winched out. It wouldn't start. eventually did and it was fast idling. not as fast as this last time. but still fast. it eventually seemed to settle and I got it in gear and by the time I was back to the truck was acting ok. chalked it up to the bike being at a bad angle in the snow.
My investigation last year lead to the throttle position sensor TPS. how to jumper the diag block to see the sensor position on the display,. I focused on this nearly sure it was a detuned sensor or broken sensor again this time.
I tore down the front plastic and stuck my head into the TPS area to see what I could see. What I found was that the throttle body assembly had actually come out of the mounting area (not sure what it is called). the ring clamp was loose I could move it easily. Hopeful, I tore down the air intake assembly above it (air filter...etc) removed a sensor clip and a hose.
I backed off the clamp some more and was able to reseat the throttle body assembly. put some blue lock tite on the clamp screw. When I was cleaning off the air intake assembly to ensure I dropped nothing down the intake, I noticed the underside of the air intake "box" also had a clamp. this screw was completely missing.
I went to the hardware store, bought a metric replacement (brought clamp with me), seated the assembly, settled the clamp blue lock tite that as well...
quad fired right up, idled normal, idled up without hesitation and dropped right back off. Cost of solution $3.87 CND for a pack of 5 metric screws. moral of my story was don't assume an idle issue is a throttle position sensor problem... there are a number of other factors including air pressure, which I believe was my issue.

I'm looking at replacing the headlamps on my 2001 KLF 300. These LEDs are out of my experience range. Supposedly they are "plug and play".
What problems am I not aware of? Other controllers, ballast?
I bought a "project" Grizzly 660, I think it has been a few people's project. The PO had it for a while and did not have time to work on it. He said the battery was good, but I don't know how he knew because the display was blank, no lights and won't crank or run.
I found a nest under the front cover, by the CVT inlet, a chewed thru wire and a few more without insulation. Rewired those from the connector (black 3 wire to the display) and replaced the fuse as suggested by a search from this site. That got the display working and power to other circuits.
I replaced the aftermarket start switch with a used OEM switch from eBay. Then it would crank a little, and started once for a few seconds.
I'm a small engine mechanic - mowers, snow blowers, etc. In my small engine work I have had a number of rider mowers that would crank about a half turn and then stop. The owners have suspected a bad battery and changed it with no improvement. Setting the valves to spec usually fixed this.
I set the valves on the Grizzly without solving the crank problem. I wonder if the timing chain could be off - slipped a tooth.
I don't know any way to check for this without pulling the head and looking at the timing marks on the cam gear.
Is there another way to check for proper timing?

It's time to replace the shocks and struts. Looking for some stiffer springs than the OEM as I use this for farm work and I put heavy loads on the rear and haul small trailers frequently. I've seen a couple aftermarket offerings that say they're 10% or so heavier duty. Any other options for something a little stronger / stiffer? Thanks.
The saga of the fan continues.
The Pin attempt in the fan shaft failed. I then moved on to trying to weld the fan hub to the fan shaft. I took it for a run the weld broke. Now it was truly F'ed. To recap the dealer price, they want $400 + CND for a replacement fan assembly.
I searched all sorts of after market places and no one carried one. Ebay had some used ones but they were $120 USD + Conversion rate for something as old as what I have. I went to Amazon and eventually settled on this.
What I found... and was amazed... was that the fan mounted to the Suzuki fan assembly bracket. I was prepared to manufacture my own mount conversions... It also came with "Harpoon mounts" (nylon zip tie like things that go straight through the rad. Anyways it mounted to the original bracket. It fit perfectly. Cut the electrical plug off replaced it with the Suzuki... all good. Let the quad heat up, thermo coupler kicked in the fan circuit, polarity was right... all was good.... Fan is under the circuit fuse rating.
so I finally have a solid fan solution. $34 CND vs $400+ CND
