Morning Colin,yes it was a great day out.Recently we have found some great lanes on the wolds,one about 15 miles long starting near Fimber.Do you like my mod for going through deep puddles and fords.   Cheers David

Hi cocorico,I am not sure this is the right  place for the reply but here goes.The filler plug has a fibre washer and ptfe on the thread so it should be sealed,I thought of fitting an extended breather but I dont think the gearbox needs a breather.The Mikuni is a VM-26-8074 and after some trial and error the following jets are fitted, Main 140 ,Pilot 25.30, Needle jet 182P4, Needle 5DP3 and the slide is a 2.5.There are dozens of combinatios of jets ,needles and slides so it is best to start with the manufacturers set and change one item at a time.I use my B175 mainly off road and the above settings work well for me,the bike starts well and pulls cleanly through the rev range,certainly better than the concentric that was fitted.

Hope you find this of interest. David
