    I have a couple TW200s and my lady and I agree a TW300 FI with a motor similar to that of the Ninja 300 ~34hp/18lbft torque, a 6th gear and we'd be elated.

    This isn't so we can go faster off-road but so we can more comfortably get to the off-road bits. We were up in Burney CA in June with some friends for a weekend and exploring the logging roads and trails was a blast but using the road/highway was as it always is not great. We love the bike, the way it handles, the low-speed capability off-road, the looks, we just want a bit more umph to get us there.

    We have a couple GS' 800/650twin for longer adventure rides and less intense off-road sections so this would fill the gap between our current options.

    I do love my TW though, it is still my favorite bike out of all the bikes I've owned.

    The new XT 250 engine is probably closer to what the little TW would end up with if necessary to meet emissions. FI - starts easily and runs well at all altitudes. GREAT fuel economy - even better than the already great carbed version. Only ever had one prob with FI. Carb bikes OTOH have had fuel proba that have complicated or prevented starting more times than I can count.

    Isn't the new XT 250 kind of down on power though?

    edit: Yes it is, it's about the same as the TW, if they were to move any motor into it I would hope it would have more than that.

    Realistically I don't see Yamaha spending the money in development to make a new motor for the TW200 considering the specific requirements for the larger rear tire(sprocket offset etc...)I can still dream though!

    A friend on a new XT250 had no significant trouble keeping up with a group on assorted 650's on a recent dualsport ride in Ecuador. She had to work it pretty hard at high altitude (up to 14,500') but managed OK.

    FYI, the TW200 is already a TW225 in Japan, and has been for many years now. Uses a modified XT225 engine with a 5-speed gearbox instead of the 6-speed. Why they don't bring that bike here is beyond me, the XT225 has significantly more power... :/

    And why lose 6th gear?

    As I understand it, the TW225's transmission is a lot more robust. Also there is an extra bearing for the super long output shaft. This is all due to the super wide, super heavy rear wheel. Basically they bolted the TW200 transmission into the XT225 motor and called it a day.

    From what I read the XT250 has about 20HP though that could be dated info, at any rate, I'm a 6'7 man, I really NEED(want) more powah(for higher limit roads)!

    So would an XT225 motor probably be the easiest swap (lol "easy")?

    I don't know what the differences are. I'm pretty sure a TW200 transmission won't bolt right in, there are likely differences in the case. I don't have a lot of information on that though.

    Heh, if you could convert to a BW200 swingarm, you might be able to more or less bolt an XT250 motor in. Likely with a lot of fabrication, but that might make it more doable, because the BW200 has the offset sprocket drive.

    The short answer is no XT/TTR type engine will be a direct swap into the TW. To clear the rear tire, Yamaha had to extend the output shaft making it longer. They then had to support this extended output shaft with a different side cover which is needed to supply oil to the outer output shaft bearing.

    The good news if your mechanically inclined is you can swap parts from a XT/TTR but there is a lot of work involved. A few have done various conversions and love the extra power but most just live with the TW200 engine as is...like me. Good luck.

    Happy reading: just to name a few threads on the topic which may help you out.

    I just picked up a 2006 TW200 with 122 original miles (seriously). I paid $2800. Thing is basically new. I have wanted to built a little mini adv out of one for years so I took the plunge. Rubs awrsome, starts right up, but sounds freaking crazy. Someone put my mind at ease that all this tapping is normal.[​IMG]

    That's pretty interesting, considering the number of people who have or would like to swap the XT225 transmission into their TW (with a custom countershaft).

    I've thought about that. BW500, anyone? :jump

    It's been done and pictures posted here a ways back with the Honda CRF 450.
    Probably a few other bike conversions too.

    Clean and shiny!

    I don't know what is normal since I haven't heard any other TW engines but mine clatters a bit and the stock exhaust is louder than my DR 650 with a different muffler on it.
    Have you checked the valve clearance?

    I havent. I just brought it home today and rode it around for about 5 miles. Seems like the noise starts once the engine is warm

    One concern is if the seller changed the oil and filter before listing it... :fpalm

    Some TW engines have suffered cam bearing failure because the wrong oil filter was used.
    The stock filter is a cleanable metal screen but is often replaced with a regular throw away filter.
    The problem is that some genuine Yamaha replacement filters do NOT have the correct holes for the oil flow. :becca

    I forget the exact number but as an example if the stock filter has 3 holes for the oil passages, the wrong filter has only 2, thereby blocking the oil flow to the head.

    If that is the problem the cam and bearings in your motor are already damaged. :devildog

    Hopefully someone can add more information about this and how to check for oil flow to the cam because I don't remember.
    I think there is a bolt on the head that you remove and check oil flow by cranking the engine.... :scratch
    I remember checking mine when I bought it (used) a few years ago but can't remember now how.
