    If thats the mill, I recall them fondly as a smooth, electric style engine that responded well to porting, pipes and could make big power back in the day. My friend Mike had one, glassy smooth.

    That's a really strange looking head and carb...

    Or... Is that top oil fed and EFI...?

    Lots of glowing reviews of the DT230 with a basic uncork and and carb adjustment.

    My only concern is weight. The DT230 (in Yamaha form) ready to ride fully fueled appears to be a piglet of 292lbs.

    I'm hoping that Pitster takes this into consideration and the new frame and other measures have been taken to lighten this up. Any two stroke gain is easily lost with that kind of weight.

    Then again, Yamaha isn't particularly known for making anything "light".

    We'll wait and see the specs. Not willing to cut it down yet!

    The TSE chassis is modern and much lighter then the DT's that for sure! We should be in the 230-235lbs-ish mark with oil injection. I'm sure a few lbs could be lost for those that want to remove the oil injection as well.

    Oh hell no! What's the big idea giving us exactly what we ask for?

    Why what seems like a price premium compared to the thumper? Is it that darned supply/demand thing biting us again?

    Looks like a dead ringer for the WR200 carby too. Here is your KDX200 with better ergos and suspension!

    Im betting with some porting and a pipe its as good as the now (forever?) gone KTM 200 engine. E-start and oil mixer on top of it? Dang.

    WR/DT 200 were not the same bikes IIRC?

    This is crazy intriguing. It sure does look like Yamaha’s last streetable 2-stroke. I was thinking my next 2-stroke would be for the D-14 Enduro series, so Beta or KTM. Maybe I’ll have to ride my old stuff longer for that.

    This could be insane fun for dual sport stuff. A mild 2-stroke in a decent frame is the basic formula we grew up with in the 70’s and 80’s. Damn good fun!

    The 4st will probably be better/faster for general trails and overall but this could be a riot for tighter stuff and acting like I’m 14 again.

    Yup, I think it’s what we asked for.

    Hmm... I've been drooling over these.



    I'm not sure I want a 2T bike. But I'm sure I'll afford a Pitster much easier than a 300i ...

    The lump on the head looks like a high flow thermostat to me.

    Port on intake looks like an inlet for an old boost bottle that Yammie used. Not sure when the oil comes in.

    Carb looks like a Mikuni TMX? I know he said it’s a Keihin. Either way, it’ll be fine.

    Doesn't look like it according to Wikipedia. We saw the WR200, didn't see the DT200 or 230. We saw the engine in the blaster 4 wheeler. Not sure what exactly the difference is but at this point I don't care. Take my money!

    I got a wild hair and bought a brad new street bike back in August. My bike budget is blown for quite a while. Not sure sure I want to pay that much to be one of the guys to vet out their TPI, but it sounds very promising. I've never had any issues with a carburetor, though. For those reasons, the bike in this thread is very interesting to me right now. I'm curious why this 2T bike is considerably more expensive than the enduro 4T ( I can't remember the call letters...LXR?) that you bought.

    My guess is my LXR is a 2016/17 year leftover and a different set of components, like the steel subframe and linkage. Im also told the build fit n finish is far superior on these TSEs.

    @Pitster is the guy to ask.

    And the LXR.... Well, I havent bought a new bike for that little since my kids were on RM80s back in the 1990s! I figure it is the exception not the rule and when compared to a $8-9000 KTM XC150/250 the TSE250 is still a screaming deal.
