    I noticed in the photo the head gasket is a bit wet, but the side of the gasket is nice and clean. Did you just replace the head gasket? If not it sort of looks like it might be leaking, or was went from being cleaned.

    Seems kind of strange they wouldn't touch it off of the 3 wheeler... Not like they needed to fix it, just replace gaskets. Really the gaskets are pretty easy to change, the most pain one to deal with is the center crank case gasket.

    Of what I can see on your machine, I'd say pop the head and cyl off, replace base gasket, and put a new head gasket on. Use yamabond/hondabond on the valve cover and ride it. Side cover and center case gaskets are just for keeping oil in the engine, unlike a 2 stroke where it can run lean from a leak. Of course with the head off, check for bad signs (scoring in cyl, valve stem seals, mating surface etc. If you want to throw some money at it, could get the valves reground and such. The machine shop won't tell you to bring in the 3 wheeler whole =).

    Thanks for all your help. I should have just rode it but instead tore it all down to clean everything up and replace bearings rebuild shocks one was leaking pretty bad. Then I figured while have the engine out figured have shop check it out good because obviously they have more knowledge than me. Don't wanna drive 3 hrs to haspen and have a problem. Be a sad day!!

    Understandable, it is always a good idea to bring more machines than you have people to ride, just never know if something will happen.

    Sounds like you're covered then =D. Lat year I bought 3 machines, year before I took 2. Never had any real problems, but brakes are strongly advised, atleast rear brakes. My 350x is front only currently, and the sx had a bent foot brake lever, so wasn't the easiest to use.
