Could you just fit a small extension onto the lever of the tap so that it fouls the kickstart in the Off position? If you ride the bike a lot it could save a lot of cable ties!

Or just put a hole in the wooden block large enough to slip it over the kickstart rubber?

Well your system certainly looks foolproof, until you just take the cable tie and wood off and receive a phone call on your mobile at that very moment. After a lengthy conversation off you go still with the oil tap in the off position. Sounds unlikely but exactly this occurred a few years ago to a member, despite his foolproof system, and unfortunately a conrod made a bid for freedom.

thanks for all the recommendations and good advice,the bike is used perhaps once or twice a month,well it will be now i dont have to drain the oil out of the crankcase and chaincase.having spent a working lifetime running a garage business i always finish the job i am doing [wheel nuts, cylinder head torquing etc] before i think about answering the phone.dont mean to come across as all knowing,but if i hadnt done this the bike would see very little use.fingers crossed lets hope all will go well and i dont live to regret this modification.

You could use one of the vacuum ones Velo use I ran velo for years and the only problem I had was in cold weather if you don’t run it long enough to thin the oil they could stick open as the weak spring struggled to close the valve
