Here are some pics of my SU for you to tell me what pipes go where.

Sorry I forgot to do this. Just did it on my phone so sorry for quality.

On my setup the breather is blanked as my breather still runs to the airbox. If you plan to keep the K&N you can run it there.

The Vac advance should be pulled out and re-drilled into the airbox side of the throttle plate if it isnt currently as its a bit hard to see from the photo.

Thanks for that Dan, really appreciate it. A couple of follow up questions, 1. Does the vac advance go to the pipe on the side of the dizzy 2. Where does the breather go to? Can I just put a filter on the end of it?

Yup the vac advance goes to the small pipe on the distributor, and that breather pipe should definitely be blocked... it probably wont run very well if you plumb it into your air system...

So even with using the k&n filter, I should block it off?

I would block it off yes. I tried for ages to get it running connected but it just doesnt work properly

What sort of things have you guys used to block the unused pipes?

I just put a short length of hose over the pipe, then screwed a bolt into the hose and jubilee clipped it together :)

Tidy, I still can't remember how mine was, been so long now. Info will come in handy.

Can I ask where you got that k&n from. I can't seem to find them any where cheap enough.

Cheers Ian

The hose from the rocker cover breather tee piece needs to go somewhere if you aren't using the airbox where it was originally connected. Hence i suggested putting it there.

Trotters SU has a K&N on it and is connected like that and runs fine.
