engine swap

Greetings, I'm hoping someone can shed some light on a little bump in the road I've come across in my build. As the title states I've thrown a NT650 / Bros 650 / Hawk 650 motor in a Transalp frame and my issue is the front cylinder's exhaust port isn't allowing me to get the Hawk's front header...

The rebuild of my '89 VK TA is continuing slowly, but just to add to the confusion, I may have the chance to obtain a badly crash damaged 650, for not a lot of money. Would the 650 engine fit straight into my frame, and more importantly, is it worth doing ? Any thoughts would be appreciated.

Well then, after all the problems I had recently with the engine swap, then the CDI/pulse coils problem, and changing my rear light as it went faulty, and also the full rear end conversion from drum to disk brake system, which included swing arm change, mounting rear master cylinder, as well as...

As I had a free afternoon I thought I'd make a start on the XR engine swap after it gave out on me just outside of Helmsley at the end of October. One XR up on its newly purchased stand. One replacement engine from a breaker, with guarantee fast running out, must get it in! Remove...

Afternoon all, just thought i'd say hello as i think i might become quite a regular. I've just purchased a CB250RS for whizzing around London on, really enjoying it so far. However, it's not going to remain standard, i'll be creating a flat track/café racer hot rod thing out of it over the...

I finally isolated where the noise is coming from on my AT this morning. It's coming from the nearside of the top end of the front cylinder, and the sound is a rhythmic knock. I'm assuming I have lateral play on the cam, though I haven't yet tried the trick where you listen to see if the sound...
