200 start I believe. This has taken awhile; I've been watching. Totally possibly though. Anything's possible.
That's just wicked, makes me wish I had even the slightest clue about how to do things like this so I don't have to rely on them to do it.
It's time they follow suit. Throw in 6 gears so the TW is much more comfortable at 55-65 with the extra power of a 250 and some architectual mods to make the thing run a little cooler, and we will have the perfect bike. Not too big like a 650 and not too small for real highway use like the 200 is. I know I know it will do it now, but it's no fun riding something that's so dang wound up even at 55. My stock Nighthawk 250 runs 60 mph at only 6000 in 5th (top) which is nice and smooth for a 250, actually it's only a 233cc. I know a TW250's 6th gear could easily do the same or better!

I started out with the Tw 200 and yes it can be done again. I tried to use all the TW parts I could so it could be done by others on the site. I took my first ride and there is a lot more torque a smile factor for sure like the bike is 150# lighter. It is running a little lean and stumbles at 3/4 throttle right now. I need to jet it before I test it again.
As for the 6 speed...1st and 6th feel about the same as 1st and 5th on the TW. Having 2,3,4,5 in lieu of 2,3,4 definitey keeps the bike in the power band, at least for now that is what is felt. Kind of a odd felling down shifting 6 gears on a TW when you are used to 5 for so many years. That is a pic of the 6 speed ready to go into the TW. More testing to come.

Holy smokes, now that is super cool. BTW I started my own build thread, and it's been super hard to keep momentum going on the build, life stuff (my job) really jams things up. Haha! SO I can relate.
So is it a stroked 200? Do you mind giving the basic details here on this thread?
Really cool work man!

I am happy to share the build and pics it just takes me a little time to put it together.
Yes stroked 200. The stock TW is 67mm piston X 55.7mm stroke=196cc the new build is 71mmX62mm=245cc. That is the longest stroke I could go and use the stock cam chain. http://crankworks.com/index.php/contact did the rebuild on the crank with a TTR 225 rod.

Okay,
Now the big question...how much to do it for all of us. I am in line first.

I finally rode his bike with his LAST motor. I kept muttering "OmyfreakinGawd" afterward and now all I want to do is throw rocks at mine.
Ronnydog's kinda low key most of the time, but today he called me after his first ride on the new motor and for the most part kept muttering his version of "Omyfreakingawd" for most of the call.
This I gotta see.
