Valve lifter

I have the same issue with my 99 .   I have no doubt a good engineer could rig up something for one cylinder .other options are a compression plate under the cylinder ,  a softer cam  from an 88/99  ,  and a change of engine and gearbox sprockets ( a bigger engine sprocket will reduce kickstart gearing  but would need  a smaller box sprocket to  retain the final drive ratio . Get the piston crowns turned to form a dish , If you are very tall a longer kickstart lever would help.and fit 18" wheels, Do the lot and  tell me how it works !.

A wilder cam with more overlap like a Combat cam will drop compression at kickover speeds, counter intuitive.

Other option is a chainsaw decompressor on each cylinder which is used on hi compression 850's and 920's but it must be done with care.

I agree in  theory a wilder cam should help , but I have  a full race cam on  my 250  single and  you can stand on the KS   or lock the wheel bumpstarting   and thats only 9 to 1 comp.  Chainsaw decomps  sounds a good option.

I've not tried...but is it possible to put it in an intermediate gear and roll it back onto compression before the first kick? Like bump starting a big single

Hi David , thats basically what I do,  I just ease it over compression first . But with a twin you dont get much momentum before the next  cycle.

Hi Roger ,I understood that your bike is a twin.  Never seen a decompressor on one but it sounds like it has been done  with a chainsaw device . In theory it should be possible to build a lever job into one of the exhaust covers  (like a Ducati 350 scrambler of the 70's). Still  only a partial job if only on one cylinder . A longer KS  would have to be welded up  from a couple of std  ones. Would only work if you can get a foot on it !!  

..looks like this. Very simple and effective.

RGM do the longest kickstart lever, it folds and is based on the T160 Trident kickstart. You need to check it does not foul anything, it fits a standard Commando but needs any rear sets to be moved backwards, well mine did.
