trialsrfun Posted August 10, 2014 Report Share Posted August 10, 2014 Which slide & jets are required please in a Mikuni VM26 carb when fitted to a 250 OSSA TR77, presumably the set up would be the same for a MAR? Link to comment Share on other sites More sharing options...
rob b Posted August 12, 2014 Report Share Posted August 12, 2014 Hi - I've tried the VM26 on a 250 Gripper but just can't get it running how I think it should run. Send me a mail and I'll let you know the combination of jets I've tried. Where did you get the carb from? Cheers Rob Link to comment Share on other sites More sharing options...

Cheers Rob Hi Rob, Unable to send a message for some reason. When the TR77 was new I believe it would have had a stub fit Bing carb. When I bought the bike it was fitted with an adaptor and flange fit Mikuni from a ??? This carb is not in great condition, neither Allen's or Motocarb seem able to supply parts for it but either can supply a new carb supposedly ready jetted for the OSSA but it would be good to know what jet & slide combination works on the 250 TR77 OSSA.

rob b Posted August 16, 2014 Report Share Posted August 16, 2014 Hi Send me a mail at rbamford@prestolite.com and I'll send you details of the combinations I've tried. I bought a set of jets etc from Motocarb and it made the bike run worse. I bought my carb from Dave Renham at Inmotion. I wouldn't have thought there was that much difference between yours and the Gripper Link to comment Share on other sites More sharing options...
