    Cool. I've often wondered if they were a 150% version of the xt225. Let us know. Hey , youve got a tach now too!

    The 350 is a great bike. Far more top end power than a 225 and is much more capable at highway speeds. It is more top heavy, which shows up at low speeds. It can be difficult for shorter or older riders to lift their foot high enough for proper starting. If it had e start it would be one of the all time great dual sport bikes.
    It was never well supported by the aftermarket and is getting to the age where parts availability may be a challenge.

    That's what's stopped me. Why are all the great platforms taken away?

    Thing is awesome. Not much higher, not much heavier, some parts are the same like the air filter and odds and ends. It's more complicated with dual intake and such but if it's runni fine I hear they continue to run fine.

    Also, Guys let me know if the pictures I post show up.

    I owned a 1985 XT350 and later a 1986 TT350. The latter had much better suspension but was not street legal. A combination of the best features of both would have made a super bike. Dual throat carb manifolds cracked, but there were no other major problems. I own a XT225 and sure wish it had one of those 350 engines!

    I changed the oil in my XT225 today, and a piece of hard black plastic came out with the oil. I found some earlier posts in this thread with similar issues but either the photos are no longer available, or the parts don't look the same as the one I found. Does anybody have an idea what part this plastic could be from?

    I haven't noticed any difference in how the bike has been running lately. The oil filter didn't seem to have anything more in it than usual: Some sludge and dirt, but no metal shavings or plastic.

    It's the end of your cam chain tensioner, the big long piece, that's broken off.

    Thanks! Do you mean one of the timing chain guides (parts 4 and 9 in the diagram below) or the tensioner itself (part 2)? Since you said the "big long piece" I think you mean one of the guides. Any idea how much of a pain is it to replace them?

    I think it will be #9. The head will have to be removed, it's not too tough if you have a manual.

    Well, friends, the SECOND Caltric stator (the cheapie, $65) blew up in the same fashion as the first- after about 5 minutes of use. Same no spark, motor cranks, same everything.

    Is there some other failure that could cause stators to fry instantly like that? What am I missing here? I REALLY don't want to buy a $200+ OEM stator and then have it explode after 5 minutes.

    Sweet Baby Gee zuz! If my XT sounded anywhere near that amazing I'd probably never stop riding it!

    What did you use to measure that temp?

    Probably infrared gun, that's what I would do. I'm scared guys, I rode the 225 to work and it's going to be 95 degrees on my way home. 50 miles.

    This is good information. After rebuilding my top end, my motor ran REALLY hot (too hot to touch the "YAMAHA" written on the crankcase cover an hour after shutting it off). It would be nice to have a baseline or database of temperatures to go from now, measured at a constant point on the engine, with environmental data given as well as specifics (after highway riding at 50 mph for 20 minutes, 10W30 oil, etc) like in between the "M" and the "A" on the crankcase cover.
    Where was the 250 degree reading taken exactly? I've got access to a laser temp measurer as well.

    I've seen some people put temp strips on the case that the temp appears on when it goes up 20 degrees at a time or whatever it has. I've seen those melt as well.

    I've seen air cooled four wheelers idle with mud caked on them all day and not have issues. I'm starting to wonder about theses 225s. Haven't heard much for issues with ttr 225s or the 200s that preceded these in three wheelers etc.

    I've had mine mudcaked and run all day. Overheating is usually indicative of an actual problem elsewhere (cracked intake, wrong jets, etc ) not the design of the bike.

    It made it home just fine, think I'll ride the 350 to work the rest of the week though.

    I was measuring on the top part of the engine case lh side just behind cylinder. I was using a small IR thermometer from harbor freight. It only goes to 250 degrees max. I was going 65 on the GPS when the temp got this to 250 deg f. Later I went to 16t front sprocket and temp stays below that at 60 on GPS at any temp I'm willing to ride.
