Thanks guys, I've emailed the UK Keihin distributor. They have similar looking jets on their site:
http://www.allensperformance.co.uk/keihinjets.htmlA couple of these look familiar, I'm hoping Allens can tell me which ones from the carb number but if not I'll have to whip the carb off and strip it down to measure the jet and compare it to their chart.
There certainly aren't any with a max size of 160 as stated by the shop so that tends to suggest they're wrong but not sure if any of the jets listed will fit my XBR...
Don't fancy buying a drill kit and trying to drill the bugger out myself!
The carb model is VE10A, is that the same as the Dommie?
Regards
Chris
