djdenzil Posted March 2, 2012 Report Share Posted March 2, 2012 My setup is as per GG UK. 45/122 Jet Sizes. JJH Needle, Middle clip. 3.5 Slide. 1 1/2 turns on mixture screw. Are you using the spacer of the GG Raga reed block assembly? DJ. Quote Link to comment Share on other sites More sharing options...
peterb Posted March 10, 2012 Report Share Posted March 10, 2012 My preference with the Keihin is to use a GJH needle, offers much better low end control than the JJH, but then you need to use a 128 main jet. Try Allens in the UK for these bits. With the GG250, the standard DellOrto works very well and fitting a Keihin did not seem to give any vast improvement, unlike the 300 model, where the Keihin noticeably improved carburation.
