CB750 / 750 k6 charging problems
« on: April 24, 2010, 07:24:37 PM »
hi can anybody give me some advice,i have a charging problem with my cb750 k6,with the lights on battery goes flat after about twenty mles,dont know if this the correct thing to do but i connected a voltmeter to the battery and it reads 12.4 volts without the lights on and down to 11.5 with them on,have tried adjusting the regulator,no difference,adjusted the points and core gap,still no change,could a rectifier be at fault,or have i got to go down the new generator route,not being an a electrical buff any help would be appreciated,it is really hard to find any secondhand parts,just mention i have just fitted a new battery.
thanks

« on: March 15, 2009, 05:06:45 PM »
HI ALL
Just fitted another set of carbs to the k6 they look very clean inside,i have a flat spot from take off from standstill,any ideas,the main jets are 115s so are going to change to the standard 120s, can you sync the throttle slides on the bench,or do they have to be done with guages.

CB750 / STRANGE FIBRE SUBSTANCE ON CB750 OIL PUMP FILTER
« on: March 08, 2009, 03:08:12 PM »
hi all
a couple of questions regarding my cb750 k6,the engine was rebuilt by the previous owner about 1,500 miles ago,so gave it an oil and filter change yesterday,i also removed the sump,on the oil pump filter there was a strange fibre subtance,almost like wool,also on the sump pan there were small black bits,i cant realy believe that they could be from the tensioners as i hope they were replaced,i could view the primary chain tensioner and it looked new,i also noticed that the return oil pipe has a kink in it,i have heard that they can break up internally,could this be the cause of the black bits,one final point i seem to have fuel coming out of the air box,could the float need adjusting,and could the overflow pipe on the carbs be blocked,the engine runs as sweet as a nut with no untoward rattles apart from the usual clutch,should i be worried about the stuff in the sump,as i dont fancy an engine strip,sorry for such a lot of questions.any advice and help would be appreciated. am lookig out for a pair of oil pipes,new ones dont seem to be available any more.
thanks
Dave.
