CB500/550 / camshaft valve timing
« on: December 18, 2014, 09:15:40 PM »
Hi all, just how easy is it to mis-align the cam sprocket by one tooth when doing a rebuild? considering the sprocket has no marks or would this matter? Im used to singles/twins but first time on a four.I had no 3 spitting back thru the carb before dismantle,lapped in all valves which were`nt that bad! so working backwards to find if a P.O made a mistake?

Hi all,i managed to get the pilot jets pulled tho it took quite a bit of twisting with standard straight pliers,they were totally caked with hard crude,had to soak in carb cleaner and careful use of wire strand from a cycle brake cable,set the float heights to exactly to 1,5cm,put them together and although not overflowing,they ARE leaking fuel,another strip down showed all 4 float chamber seals are squashed flat almost the whole way round,may be able to prise out and clean,turn over and reinstall,failing that they will need replaced.Fuel hitting plugs 1-3 with 1 flooding,no fuel at 4 and 3 spitting back thru carb so suspect valves not seating which is todays job! Thanks for all the relys and input guys!

Hi Thanks for all the Greets and comments! feel at home already haha Im Thinking the P.O changed the wheels due to the weight of the fairing and the two panniers i removed,the front having the extra braking power of the disc brakes,not sure tho.3 of the orignal pipes are good except the bafles look like they have collapsed? the other pipe is blowing but may be sorted.I am at this very mo looking at the carbs on the bedroom floor lol,it was getting cold/dark up the garage so took my work home with me,the carbs are,i believe fully functional/clean but it was real tricky getting the o-rings/washers back into the slow running mixture orifice! finally used a wooden tapered artist paint brush to locate the rubbers.i see the float chambers for this carb should be 14.5mm? would it hurt to set them at 1.5cm which is what i have on my ruler? thanks everyone i`ll keep things updated!!

Hi all just getting back into the motorcycle scene,picked up an aged honda cb550k,garaged for 25 odd yrs,everything seized as expected but coming along just nicely,lots of tlc needed but will get there,got the engine turnig over now tho a squeel from no 4,never seen carbs in this condition in my entire! float chambers still full of what is now varnish and now tainted red,slides jammed solid,alternator,clutch,brakes the list obviously goes on! have spent 3 weeks on it now and electronic ignition system is fully functioning,starting system all set after overhauling the motor! FINALLY figured out the annoying clutch/diode saftey mechanism! after hours of studying wire diagram to work out it only basically stops the nuetral light from coming on Grrrrr.The P.O has changed it to alloys and twin front discs which looks quite cool so may stick wi that,Im doing away with the full rickman touring fairing which is in amazing condition so will get that posted for sale,anyway,glad to be here and finding out lots more about these bikes,ttfn
