650 to 750.. But only temporary!

Like many of the Coventry makes, Triumph had their roots in the bicycle industry, beginning motorcycle production in 1902.

650 to 750.. But only temporary!

The 6T's engine is a little tired, i've no idea how many miles its covered and i've no idea what the cams are like.. soooo i'm going to utilise the 750 lump from the Chop as a temporary replacement until I get the 6T's sorted. It'll be going for a dynamic crank balance, along with a few other bits and bobs to (hopefully) up the power a bit.

But.. I've no idea if the 750 lump will fit. Having never done this before.. I've got a couple of questions. Firstly, is the 750 top end longer or shorter than the 650? Will the 650 exhaust pipes still fit.. and lastly will the engine mount holes be on the same centres?

650 is 1966.. 750 is 1974..

After some digging around.. the 750 top end is a little shorter, so have had to get 750 down pipes. Should have the motor in by mid-May.. Would be nice to go to Jersey on the 6T at the end of May.. :220
