Hi Yoda. The timing is still spot on as it is factory electronic and cannot be altered and the fuel I am using for testing purposes is from a clean seperate resevoir I use for all my carb work ( damn tank just gets in the way donchano ! ) as for the spindle seals you refer to I guess you mean the ones on the butterfly valve shafts which on visual inspection look ok but after standing for 8 years who knows ? You are right to say replace all the rubber but as I am finding out here in merry olde England parts seem to be unobtainable for this machine so if you or anyone else knows of a stockist please enlighten this ageing jedi who is starting to stray to the dark side ( use the car more often ! ).

The bike has done fifty odd thousand miles but was apparently running fine before its long storage. The carbs on my Honda have done twice the mileage and are still all original.

Hi folks Ive recently aquired an XJ750 Seca 1982 vintage which has been stood for 8 years so the carbs were well and truly full of varnish. So they have been completely stripped, cleaned and rebuilt with the appropriate Dynojet kit and K & N filter for good measure. My problem is now that it will start without choke, will not idle happily below 1500 rpm and the revs will start to rise and race for no reason. Altering the mixture and balence screws makes no difference nor does putting the standard jets and needles back in. If anything it runs slightly smoother with the Dynojet bits. I have rechecked all the linkages and cleared out all passages carefully many times but still get exactly the same results. Although I have spent many years riding and maintaining motorcycles this is a new one on me ( just been lucky so far I guess ! ) so if anyone out there knows what is wrong or can point me in the right direction I will be very gratefull as the time it is taking me to type this is the only thing stopping me reaching for the big hammer !
