Ok, another newbie post here. Checking this stuff out in issues with lost compression. Wondering if anyone can tell by the pics and video of the cam is good, and whether you can see anything visibly with the valves and timing gear.
Any input would be a great help. Been researching youtube videos, but just not sure.
2000 Bayou 220
I could test the exhaust, it looked like it was opening, closing and seating ok, but not sure about the intake.
CAM - looks like some wear on the outer ridges on both in spots, and one lobe to me looks kind of weird, but I don't know.
I have a 2006 Bombardier Outlander 400 that I purchased new. I use the Outlander for hunting and working around the acreage. Muffler has worn out with holes in it and I am looking for a replacement. From what I can find, factory mufflers are no longer available. Are there any after market mufflers that can be found that fit without having to hire an expert welder to get creative? Not looking for high performance, just a good quiet muffler. thanks
I purchased a quad with engine problems. The previous owner had pulled the motor and pulled the valve cover but decided to stop. I have done Arctic Cat top ends before but have never worked on the bottom end so any advise would be appreciated. What I have found so far is the connecting rod bearing is completely gone and some scoring on the jug walls. What i'm wondering is if anybody here has worked on these and if so did you replace all the bearings or just the ones that were for sure bad? Also is the 2006 Suzuki King Quad 700 motor exactly the same? It seems Suzuki parts are a lot cheaper to buy.
Looking for a guru to help me get the top end back together. I'm stumped!! There seems to be an issue with the removable chain guide on the left hand side. In its current position (which is probably incorrect) there's not enough clearance to get the chain on the sprocket and be able to line up the timing. Does the guide rest on the side or is it supposed to be in the notch underneath? I have a manual, but it doesn't show the correct positioning on that guide. I tried to fit it in the notch, but then the cylinder head doesn't seem to seat properly. Let me know if you need pictures. Any help (and pictures) you able to provide will be greatly appreciated.
Thanks in advance!!

About a year ago I replaced the carb on an Bruin that I bought from a relative, I replaced it because it was gummed up from bad gas sitting in it for a couple years. Replaced the carb, and ran it a little bit and it had a problem of the carb popping whenever giving it throttle. I assumed this was just a fuel air mixture I needed to adjust, but I was lazy and just let it sit for a few more months. I went to adjust it just now, but I don't know if I'm slightly retarded, but I can't find the fuel/air mixture adjustment screw anywhere on the damn thing. I've tried nearly every screw I could find on it without taking the whole thing off (Which is a pain on this atv). I'll link some pictures I have from ebay on this carb. I also checked manuals and diagrams of the carb and could not find anything anywhere. Please spare me from my complete ignorance.
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.
Recently, I changed the timing chain. I lined up all timing marks and set valve lash at TDC. The mark on flywheel was on point as well when I looked through sight hole. I started the engine and starter turned it over then it hit and stuck. I did it one more time and the same thing happened. I took everything off and saw no damage. I tried to turn it over by hand and same thing. It turns halfway or so and hits. I loosened valve lash and took crank gear off and it does the same thing. It will turn over clockwise fully but not CCW. It seems like the crank sub assembly weight is hitting the gear balancer weight. I can turn crankshaft CCW while turning the gear balancer CW and get it to go but feel it hitting something. I also can spin crankshaft CCW without crank gear on and force the engine to break past the stick. It’s not the piston.
Please give me some suggestions thanks
I registered on this site because I just purchased a new to me 2005 Yamaha Bruin 250 2wd. This seems to be the only place to get diagrams so I'm hoping I can download them sooner or later. The guy I bought it from said it had no spark. And it truly does not have spark...lol
I haven't looked into much on it. Looks like he replaced the ignition switch and the stator. I'm thinking CDI box but I want to check the coil first.
I look forward to helping others out on the electrical end of the world. I am an ASE certified automotive electrical technician. If it's 12v, I can usually figure it out.
Yamaha BRUIN 350 Quad
Hi, think water got into the tank, have managed to drain fuel (not the best experience) and empty the carb of fuel ........ so it starts now and runs however, it cuts out on fuel and won’t restart, it will restart on reserve ? When I turn it off and back onto fuel, it will start again. If I take for a short run on fuel it will cut out again and only restart on reserve 😳. Any ideas what else I can check. Many thanks
