Is that a TR6 hiding next door? I'd like to see more of it.
Your 550 looks great. You will have to change its name from Scruffy to something more fitting.

Yes, you are correct it’s a 1974 TR6

Being a UK car it has Lucas mechanical fuel injection, the US got a depowered car with twin SU carbs.
Car looks standard and is in nice condition, lots of rebuilding of bodywork, mechanicals and interior, and better braking to go with the 2.7ltr 175bhp engine.

Nice motor mate, love the TR6. And yeah, you're definitely going to need a new name for the bike - Scruffy isn't working anymore

I’ve decided to call and end to Project 550 - The Scruffy Racer.

not happy with the tank, i’m worried there’s more rust hidden beneath the old filler and the whole lot needs to go back to metal and be redone.

so i’m going to ride Scruffy about for a bit then plan Phase 2

thanks for all the help and comments, look out for the next phase in the Autumn :)

Sorry to hear that - what makes you think there’s rust under the filler? Is the inside of the tank rusty too? Or is the paint not laying flat?

Small update !

i was right to be worried anout the old filler, turns out to be hiding a couple of small holes!

the ethanol laden fuel caused the paint to bubble around the offending area, so i ground it back to bare metal and repaired with QuickSteel, refilled and repainted.

repair seems to be fuel tight after some testing so today am gojng to clearcoat as its a nice dry day.

Yes M butnless than ideal!

clearcoated today which seemed to attract every flying thing for miles.....

tomorrow will sand and polish the clearcoat and see how it looks.

it’s been an interesting journey, the ‘no dents no filler’ tank wasn’t exactly honest!

I’m back from a 6 week break and Scruffy fired right up.
tank looks the same as when i left it, no bubbling of the paint so the quiksteel seems to have worked
initial fuel leak cured itself after a ride, stuck float i’m guessing

so..... must be time to tear the motor down and fit 600cc pistons !
shall also repaint the engine, forks etc , fit better shocks and maybe cartridge emulators
look out for updates !

Ordered the Cartridge Emulators today hoping they’ll take the harshness out of the ride, otherwise Scruffy is running great
