dadof2 Posted May 11, 2014 Report Share Posted May 11, 2014 http://www.splatshop.co.uk/catalogsearch/result/?q=Mikuni+pilot Try the above link for jets or Beta UK. You could also try Yamaha dealers like Nigel Birkett.( Birkett Motorsport) When I replied to your earlier post about jets I was thinking you had a 125 with a Dellorto. Carb on an 07 250 should be Mikuni VM26-208 with a 150 main jet and 30 idle / pilot jet. Quote Link to comment Share on other sites More sharing options...

dadof2 Posted May 12, 2014 Report Share Posted May 12, 2014 I don't know for sure, looks like it may be a 32.5, see http://www.motocarb.com/mikuni-pilot--air-jets.html Quote Link to comment Share on other sites More sharing options...
