As I almost lost the endcaps of my two speeders exhaust during the last rally I may want to make a new one all the same next winter. I know my current exhaust has been made by a previous owner and might not be to the right dimensions. The exhaust now fitted is 31 cm wide. The total witdh over the tube that sits in front of the frame and that is used to fix the exhaust to is 22 cm. My block is of the narrow exhaust stub type.
Here an older picture of my exhaust:
And a picture of a bike I saw at Abbotsholme last year:
The way of fixing the exhaust to the frame differs. But the tubes on the frame of the Abbotsholme bike seem considerably longer.
Does anyone have the right dimensions or, even better, a drawing of what my exhaust should look like?
