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.
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?

I have just got a 1995 Bayou 220 from my brother. It is in decent condition ant it has not been used much, yet it has been sitting idle for a long time (4+ years).
The plan is to overhaul it and move it to a location where it will be used 4-6 times a year, so, beyond having the battery charged, the idea is to have it ready and in good condition. It will be stored in a steltered place while waiting to be used.
My questions would be: 1. What things should I carry out as basic overhaul tasks / 2. What are the typical aches, things to watch out for in this model/year.
I definitely plan on changing all the fluids, filters, battery, cleaning the carb, etc. but any specific recommendation from your experience will be of great help.
thanks in advance!
How do I replace the pinion clutch shaft in a 1987 Suzuki LT230 quadrunner? It starts up on the first kick but when I put it in gear it wants to kick up. I can give it gas and put it in gear but my clutch lever isn’t doing anything. SOS

Problem: The ATV starts and runs at idle perfectly. But as soon as I open the throttle, the engine starts to slow down until it stops. On the attached video you can hear the sound of how it works: see video below
Prehistory: there is a Polaris Sportsman 500 1998, which for about 1.5 years stood in repair, including also replacing CDI with one taken from the same ATV. Finally, the vehicles were on wheels, traveled several kilometers and overheated - forgot to fill the antifreeze Came back home in small moves. The next trip started well, but after 10 km there was a feeling of a small drop in power (even as the vehicle got warm completely) but still drives. Next trip - the situation is repeated. The next test of ATV through time and a huge loss of power from the very beginning. The engine sneezes, does not want to go more than 5 mph.
What has been done: the carburetor has been replaced with a new one (inexpensive, $ 40), a new spark plug, a new ignition coil, the engine head has been removed, the piston is in good condition, valves were corrected - but the problem was definitely not in them.
Ignition control unit is suspected. Who faced similar? Please help in solving the problem.
Thanks in advance.
I bought a Honda 250sx 1986 but the exhaust is broken. Apparently it's not possible to order a new one. I checked to order one on others compagny but there's noting.
Do you know which exhaust it's possible to install. Is there a company who sold an exaust to fit on my 250sx.
Sorry for my english
Hello, i recently bought a 2000 Suzuki LTF500 semi-automatic. I was riding it and found out that its hard to shift into 3rd gear and above. could it be because of the tuning because the rpm might be to high, cuz in neutral it would sometimes rev high by itself? or could it be something in the trany?
Also it shifts easily when off
Im working on a old 1987 honda 125 4 wheeler in the school shop. It will start by getting pulled by another 4 wheeler but wont start with the pull start or Electric Start. When you pull start it it tries to start but when you try the electric start it just turns over but doesnt even act like it wants to start. The spark plug is dry and it shoots fuel out of the back(air filter side) of the carb. Weve had the carb off twice and it is complety clean. What are some things we can try?
