TOPIC:

As I get started on my 2nd Nordwest I am now coming upon what I think is a normal problem namely that the inlet rubbers are perished or just plain old.

I notice from other posts that 2nd hand good replacements would appear to be thin on the ground, so something to look into.

I now have a 92 model with the square inlet manifold and a 91 with the RC600 separate inlet manifolds on - so yes I have both options!

My 1st question is does anyone know if the carburettor was fitted to any other motorcycle, I think it was on one of the Yamaha big singles, but would like to know for certain.

If so then, with a bit of luck they will have used separate inlet rubbers, they will still be available and I can put together a conversion kit.

Basically I am looking at CNC machining both types of inlet stub from blocks of solid alloy, that will have a grove to take an appropriate rubber that will then mount the carb. So in future an owner only needs by replacement rubbers when they rot out.

Hi Chris,
The Yamaha 600XT used the same TK carb, I have bought seal kits and float valves from www.yambits.com.
I cast a few manifolds and fitted rubber stubs into them as you suggest, pm me your email address and I'll send a picture.
