Just fit on on the 80, I doubt very much the y piece was ever set up on the dyno so you will be returning it to standard, as it should be. I suspect that it will improve running etc. Its a no brainer.
Rob - do you need a hug?
Don't do that Rob, I've bought one from the part number you supplied. The stock is in Germany so a few days to arrive then I will report on the quality! At that price it was worth getting one for the future? So a big thank you for the info

You already owe me a fiver !
I was going to whip the one off my lads bike and give that a go but sod it may as well buy a new un .
I thought the Basic made 50 bhp
Is it 44 at the back wheel.

Basic!! That's a 1000cc bike. The basic makes a lot less than that (probably 37 BHP). Wrefords tuned 800 bike with a Siebenrock 1000 conversion and a high torque cam made 42 bhp.
That was my 100PD all standard apart from the Keihin down pipes (with no balance pipe) and keihin Y piece. Putting it back to standard down pipes and a standard collector took it to just over 50 BHP.
My Basic look alike bike makes 55 BHP at the rear wheel
This is from its first run with a rich mixture on the mid range (standard collector and downpipes). 9.5:1 pistons, larger inlet valves and 336° cam.
Needle dropped. and slightly smaller main jet fitted
My Moorespeed engine is around 70Bhp at the rear wheel
I'm upgrading to a Denso starter as well...
