good morning friends,

question: what about the XT250T (81' 84') engine, with the twin cam and 4 valves?
Nobody did some experiments? It appears to have 27 hp 🤓

buona domenica.
It has been attempted and a thread posted about the process. In the end, the member gave up and now has the motor up for sale. Use the search feature and I'm sure you'll find it and read all about it.

Funny, and not so funny, how names and nicknames translate literally and culturally. We were in the big city (Portland) looking for our next truck. I love vehicle shopping but dislike dealerships. But, we were there, at a dealership.

The first one to swoop in for the kill was the most handsome man I have ever seen. Tall and slender with the persona of military leader, he was that person who immediately made a man or woman want to be liked by him. His hair was dark and his eyes were black. His skin was as dark as my left arm when it is severely tanned.

Before you ask... no. I am not and I suspect he was not either. But I recognize handsome, and so did my Wife.

The man had a deep, gracious sounding voice that didn't hurt his overall charm. His first name was Magot.

Try to imagine keeping a six-year old, precocious, homeschooled, 100% boy, from giggling like he was in a cage full of Malemute puppies upon hearing that name.

Patty had him by the hand but was having no luck with the motherly sshusshing. Our new friend started to speak but I held up my hand and said I'd get a handle on it.

I told Jake that it is fine to chuckle about something that is truly funny like a cartoon or a joke book. But laughing about something you don't know about can be very embarrassing.

I asked Magot where his family was from. He said he was born in Iran, but had been an American Citizen for two years. I pretended that I had suspected as much and heaped on a bunch of baloney about how there are a great many lranian baby boys that are named Magot to honor a great General who had lead the armies that fought off Attila The Hun. I said it was as much an honorable name as George would be in this Country, as in George Washington.

His eyes were wide and he offered a solemn apology. I told him he would learn all about it as soon as he could read grownup books.

We didn't buy a truck that day. As we were leaving, Magot led me aside and out of sight before slapping me on the back and congratulating me on how full of shit I was. He said he had to really dig deep to keep his composure during the whole show. Said I oughta sell cars for a living.

Jake was about 12 when I told him why I did it. I think he learned a lesson.

For all who read this. This thread is getting off topic.
This thread is about
"List with parts you will need to upgrade your TW to 214, 225 and up to 250 cc"

And not:
  • meanings of names
  • I got these parts
  • does someone installed this engine


Read at first the complete thread, than ask questions.

Hi,
it's possible to use nearly every engine with the TW frame.
BUT the frame needs modifications.
You need someone with good welding skills and it could be, that the frame will be useless when you've started with this mod.
Keep in mind, the TW has a wide swing arm and the TW engine has a big offset for the sprocket.
The "new" engine do also need a big offset for the sprocket.
Greets,
Sebastian

  • 71 mm piston with 8.7, 9.5:1 or 10.25:1 compression ratio
  • original cylinder can be used, but needs new 225/230 sleeve
OR
- 225/230 cylinder (70.00 mm std. bore)
OR
- 250 cylinder (71.00 mm std. bore) can be used, but than you have to use the first oversize (71.50 mm)
Hi there I am a bit confused by this. If am using a brand new YFM250 cyclinder 71mm standard bore, can I use a 71mm Wiseco 10.25:1 piston? Why does it state I need to use the first oversize (71.50mm)?
