Fit the cable end into the hole wrapping the outer cable over the quadrant into it's groove. Then locate the outer cable into the bracket leaving it loose. Then repeat with the lower cable. Fially adjust the two cables.Thanks got it sorted! Cheers Brian 3

Hi,
I just finished re-conditioning my carbs.......I labelled the throttle cables 'top' and 'bottom'. The 'top' cable pushes when you open the throttle whilst the 'bottom' cable pulls . I have the carbs and air box reinstalled. I am having difficulty re-fitting cables just wondering is there an easy way to do this? and do I have orientation of cables correct? Thanks in advance Brian [ Guests cannot view attachments ] 4

CB500/550 / Re: 1978 CB550 FOUR AIR BOX CONFUSION« on: February 18, 2024, 09:46:46 AM »I can't really add much to this except that I have used a 500 airfilter on my 550 as suggested by Bryan and Ken because I was missing g so many of the original parts. I'm still missing the F model airbox lid but I'm going to make a fibreglass one to fit under my modified seat pan. Hi is that the port on part 12? To be honest I am not sure. Out of interest , how did you blank of the hose ports etx Brian 7
CB500/550 / Re: 1978 CB550 FOUR AIR BOX CONFUSION« on: February 18, 2024, 09:19:26 AM »The bolt is part 29 with the nut 15 inside the airbox, at the top 29 and 14. Hi Bryan, I think I have eventually taken you advice ( I think you advised this in a previous post) Just looking a little more advice if you don't mind? 1. Block off ports as circled in yellow? 2. remove gubbins from inside ( marked in yellow ) 3. Insert cb 500 air filter. Is there anymore adjustments to do? Have you got a year or part number for the air filter? I don't want to buy the wrong one? Also I have the original PD46C carb.......fully cleaned and set up with original jet sizes ( main 90, slow idle 42). Do you have to make any changes to carb? Sorry for all the questions...I am new to trying to sort out my own mechanics etc Cheers Brian [ Guests cannot view attachments ] 8

Hi sorry for the hassle but I have confused myself. I have attached a diagram of air box which I have numbered 1 to 4 in red . I have a few questions, if I may: Number 1 ( part 23) . Where does this go to? Can I block this port off ( see number 2) Number 2 ( part 22) . I think this id the breather for the Crankcase and should be attached to crank case? However I am thinking of doing away with this, allowing crancase breather tube to hang loose and blocking port on airbox. Number 3: ( part 17) does this tube hang loose from port on part 12? Number 4 : which bolt goes here? i.e 15,14,3 etc Apologise for my lack of knowledge ! Thanks in advance Brian 9
