So seafoam and similar products work really well in car engines so i was thinking...why not use it in a small amount in a quad engine? im sure my 730 has some buildup (has about 75 hours on it now) so i was thinking it could use a good cleaner to help get rid of and burn off the carbon deposits on the valvetrain especially.

Any thoughts on this?

 

I would think you wouldn't need it. As long as it it jetted properly and you drive it like you stole it there should be very little build up on the valves.

I just has my head off my 730 to do some porting and the valves were very clean, it had been together for about a year.

 

I have know people to use it after they have gotten water in the engine. Just use it proportionality and it should be fine.

 

I use it like it is going out of style. In every engine I own. It keeps the gas from getting old (important in the lawnmower, weed whipper, chain saw, sled, and ATV) and will clean out anything that may happen to form inside.
