heavywrecker Posted July 21, 2014 Report Share Posted July 21, 2014 (edited) I'm in need of a speedo for my 3ta. Not interested in cheap Indian made copies. What I have is the square type speedo drive with the cable drive at the top looking at the rear hub from the right. . 1961 would have had a tick-tick -tick chrono, originals are terrible price! Any ideas on a little trials type? ratio would be 2:1 Cheers Bill Edited July 21, 2014 by heavywrecker Quote Link to comment Share on other sites More sharing options...
jon v8 Posted July 23, 2014 Report Share Posted July 23, 2014 I don't think you are going to find much help on here.most folk using Trumpy twins in P65 trials try to lose as much weight as possible,so either don't use a speedo for closed to club events or would use a mountain bike wireless one for road based events like the Sammy Miller series. Jumbles like Kempton park are probably your best bet. 2 Quote Link to comment Share on other sites More sharing options...
heavywrecker Posted August 7, 2014 Author Report Share Posted August 7, 2014 (edited) Thanks. Tried a MTB wireless one, no good, waste of money, the electrics on the Trumpet interfere too much , works fine on my MTB though! Back to the drawing boaed, as I haven't exactly been inundated with answers LOL ! Edited August 7, 2014 by heavywrecker 1 Quote Link to comment Share on other sites More sharing options...

Back to the drawing boaed, as I haven't exactly been inundated with answers LOL ! Have you tried one with a wire yet? Works fine on my Bultaco (and on my modern bikes) Quote Link to comment Share on other sites More sharing options...

Back to the drawing boaed, as I haven't exactly been inundated with answers LOL ! So do you think its any better on my AJS or Ariel ! On my Ajay it reads 3 mph however close to the 25mph max,(My guess at speed,its where my eyes blur with the vibration...) I get. A Lucas racing mag and copper plug lead were not designed with wimpy wi-fi in mind. It does work OK with no engine if I spin the front wheel or roll it down the yard.My feeling is that in the eyes of the law I have made a reasonable effort.(Plus there aren't many speed limits I could break even if I tried !
