Exhaust valve cleaning

[Rodgco]

How often do people clean your exhaust valve? Yearly? Or never

 

[dgiles]

I buy every 3 years, so never..

I have 2500 miles and havent cleaned mine yet. Still runs like it was new. I have heard that as long as the CTEC oil is run they hardly ever get dirty. I cant verify this to be true. The procedure makes it a cumbersome service, one I'm not to excited about ever performing

with the ctec oil it's really not an issue

One can only take one side out. If I remember correctly the clutch side can only come out when you take the other cylinder off.

Never, 8,000 plus miles.

The pin holding the blad to the side valves can come out ether side.

Yes, you can do either side. The pto side just take more work. You may not need to clean, but should check your cable adjustment once a year or two.

Good video^^

It's the inner small part of the valve that needs the cylinders removed to clean. One on each side is inaccessible without removing cylinders. The main blades come out fine without removing cylinders, and those are what get dirty soonest. I check them by unhooking the cables from the servo motor and ensuring they snap shut and open completely relatively easily. While there, check cable length and adjust if needed. My valves were pretty dirty last season, sled had ~1500 miles. I could feel them hang up and not hit a positive stop when opening them by hand. Not sure what the previous owner had done in terms of premix or oil type or riding style, those could all play a role. But they operate smoothly once cleaned.
