TR5 is where its at, or put a 5/6 engine into a 4(not 4a) and you'll have alot of fin with a live axle!
Edit, just seen its got an RTR front arb kit, i helped the development of that on my apprenticeship!
As in Revington? Do you have an idea how much these engines will make on triple webers?
TR6. I have one.
Althouh it looks nothing like that lol Weren't the Yank models de-tuned to meet silly Californian regs? And carbs instead of 'PI'? Mines a '72 150 bhp model with o/d. Can't wait till I've got room to start restoring her!
Yeh, its why not many got sold out there due to the lack of performance and americans wern't keen on the looks, the 7 was designed entirely for the american market. and unfortunatly it flopped which pretty much killed triumph in the day.
