Unless someone has one for sale, I will be looking to have a 2″ exhaust made up (don’t know where yet) for my 1930 TT Rep. However, I notice on that the old (now totally useless and falling apart) exhaust did not fit without both pipes being dented to miss the frame down tubes just after exiting from the head ports. Is this normal for a 600cc PY (sprint) motor?
The measurement of the exhaust ports are 1 15/16″ wide x 1″ deep and measure 2 7/8″ between.
Also, I am after a pair of inverted handlebar levers, if anyone has some to sell.

The original pipes were made so as to avoid indents to miss the downtubes, but pipes supplied for donkey’s years have been “not quite right”, and need the indents to clear the frame. The other problem with these replacement pipes is that the short pipe from the left-hand cylinder enters the main sweep at almost 90 degrees, which upsets the gas flow from the R/H cylinder.
If you borrow the jig that I mentioned you will see what I mean.
I have new inverted levers for 1″ bars at £88 per pair.
Hello Chris, I had 6 sets of 2″ LH exhausts made up for Paul Rickards (who is the Scottish section scribe)using the jig that Brian has mentioned. I kept one set , Ithink that Paul had two and the others were to go into the spares scheme.They were very well made, there was no” necking” on the bends and the welding was excellent. I can’t recall how much they cost but Paul , being a Scotsman, may remember! (sorry Paul). Jeff Reed.
