Re: Help: Fitting a radial master cylinder to a 929!!!
Digging this thread out again as I've got a bit more news on my quest to fit a PT Racing m/c to my 929!
About two weeks ago I managed to source RHS (right hand side) switchgear and a throttle housing from an RC51 (VTR SP1 here in Europe), fitted it all up nicely although I had to move the throttle a little bit out from its normal position.
The big headache, which I didn't know at the time, was the banjo bolt. Just to recap, the PT Racing billet m/c (other makes such as Brembo might be the same) hasn't got a brake light switch so I had to use a Goodridge Double Banjo Bolt with a pressure switch to get a working front brake light. Basically its just a normal double banjo bolt with a sealed pressure switch on the hex end of the bolt, two wires come off it which then connect to the normal brake light wiring. I wired it all up and worked first time...so I though: great!
Friday I took the bike to work just for a "shake down" run as I had a track day the following day and noticed a little bit of break fluid leaking from the small gap where the pressure switch fits into the banjo bolt....I couldn't believe my bad luck! Rushed to a parts dealer after work and bought a regular double banjo bolt which ended up being too long....DAMN.
To cut the story short, between risking the pressure switch popping out after 3-4 sessions (and myself ending up in hospital) and sacrificing the braking performance....I ended sacrificing performance and fitting the 929's original m/c at 10.00 the night before the track day.
I've already bought a proper (M10x1.0) double banjo bolt which is the correct length but of course I'll be left without a working front brake light for the road...
....any ideas on how to get a front brake light switch working WITHOUT a stupid pressure switch?
