Hi Prutser and gang.
Yeah I know if you were interested in doing a build thread on the ST then you would have done it. But working on the assumption that until you say otherwise you will respond favourably to more ST focussed questions.
When looking at the pics I cannot see any frame strengthening as per HPN. Did you do any?
What length did you extend the swingarm by and what was the rear shock length?
What jet sizes were you running on the bing carbs and finally what was your fuel range?
That old beemer ST sure will convert many sceptics and boy it sure looks cool.
