Not sure but my guess would be late timing. Your cam chain could be stretched. That could cause your valve opening to be off and the fuel to be burned a little late (while it is exiting as exhaust) and could cause the header pipe to be hotter than normal. This can also lead to burning a valve so be carefull and have it checked.

 

HEY BUCKAROO50 HOW DO I ADJUST THE TIME ON MY ARCTIC CAT ANY HELP WOULD BE GREAT THANKS.

 

Not sure about your machine but most are not adjustable. You have to change the timing chain.

 

HEY BUCKAROO50 HOW DO I ADJUST THE CAM CHAIN ON MY ARCTIC CAT I THINK THAT IS WHAT I NEED TO DO. ANY HELP WOULD BE GREAT.

 

There is no timing adjustment. If the chain is stretched you must replace it.

Some times this is casued by a rich condition inthe combustion chamber and the fumes are burning in the exhaust. Check your plug color.

It can also be casued by a burnt valve or if valves are out of adjustment.

I would start with the fuel mixture by checking the plug color and then look at the valves.

Unless it has over heated, or has 15000+ miles it is probably not a stretched timing chain.

Not sure on your machine but my 400 there is no adjustment for timing. The only thing that can be done is with the chain tensioner. I took mine out and there is a little spring in there, I stretched it a little 'like you can do with a ball-point pen', just to make it a little more stiff. Other than that there is nothing you can do short of replacing faulty parts. Oh you can adjust the valve lash. And you can change the gap on your sparkplug to change the timing a little. "Narrow gap = retarded timing", "Wide gap = advanced timing"

I am narrow gapped - retarded.... lol.... All the lights are on but no one is home - hehe.

 

Anybody know what the intake and exhaust valve adjustments are?
any help would be great.

 

I do for a 03 but not for a 1996, check in your owners manual, or call the dealer would be my sugestion.

 

Hey Buckaroo I was just wondering my ARCTIC CAT has a honda carb on it it runs but not to good could this have anything to do with it not having no power and being sluggish?

any help would be great thanks.
