Throttle Cables??

[Ericcb750]

Hey Guys,  I am almost finished with the resto/cafe build of the CB750 K . I've posted some pic's on my **Turn Signal Question** Thread in this section. They are normal size too! I'm wondering if anyone could give me some advice. I have clubman bars on my bike now and i'm having some issues with routing the throttle push/pull cables. The Springs on the carb linkage are amazing they snap back perfectly but once I hook up the cables it feels a little bogged down. I've tried routing them in a few spots and i've gotten them to where it does snap back but it's still slower than it should be, even the pull cable feels a bit tighter than normal. Should I need new throttle push/pull cables now that I have lower bars? Anyone run into this issue before ? Thanks for any help guys, I appreciate it. Take it easy.

I don't know if that would change anything but Dime city has shorter cables.

Cable routing like this can be tricky. It's pretty much trial and error until you find a setup that looks nice without causing any issues.

Don't overlook the adjustment that is built in to the pull cable sheath itself. Not just adjustment at the carbs. That little adjuster can make a world of difference when it comes to a smooth acting throttle. It's there for a reason!

Thanks for the help guys, I guess it will be a trial and error type thing until I figure out the best spot for them. Hey SHINYRIBS, You asked me to post some pics of the bike. Were you able to see a few of them in my other post? Just curious.

Also, i'm having some Accelerator pump issues. I'm not sure what the problem is because I cleaned the carbs really, really well. I put in a new Accel pump diaphragm and everything but I'm still not getting the little spray out of the little copper jets in the carb throats? The old pump diaphragm didn't have any holes but it was pretty ugly looking. Is there any other tips to cleaning these out that I may have overlooked?? Thanks again everyone for the help, It is greatly appreciated.

Hi.  

   On vacation now, not close to my bike, but I do have clip on bars mounted on forks under triple clamp.

   My bars are low, and I do have a CB750F DOHC.  Yours isa. K, so it should be very similar. The gas tanks are a little different, but the other than that it is same motor and related parts from the carbs onto handlebars.

   I remember once asked a guy to help me with a valve adjustment, I did not have my tools back then, and I asked him to change my cables at same time, he would not charge me fpr it, I paid for the cables, I diday for the valve adjustment.

   When I got the bike back, the canles bound up, upon tirning the handlebars, cables seem to bind and crowd the area where it wass uppose to slide, right into and under gas tank, nextt o steering stem.

    I checked a Honda CB factory manual I have and there i saw cables have a way of running from each side (throttle and clutch) of handlebars onto side of tank at steering stem and beyond under tank onto carbs and clutch arm.

   Throttle cables have to leave carb hook up points and run toward handlebar on opposite side of throttle grip. So throttle grip is pn "R" side, cables should run on "L" side of tank 's underside (left and right as seen from a seating position on bike)

    Cables exit over tank mounting rubber (round side rubber where tank affixes itself) and on left side of tank and steering stem. Then run from that opposite side overt o right side of handlebar, over headlamp.

    Clutch cable does opposite, from right side of under tank and frame, exit at right side of steering stem, and crosses over to left side (clutch lever) over headlamp.

    Running throttle cables on right side(same side as throttle grip) and clutch cable on left side of tank and steering stem( same side as lever) will make cables crowd and bind area and performance of cables will suffer.

    Check your cable routing.

    I have regular - Stock lenght cables and routed properly it is ok.  All the extra cable just loops at headlamp area.

    Also, I think there is a difference between US cables and Non US - Euro cables. None US might be shorter, because many US bikes came with weird tall handlebars.

    Both Euro- non US and US are available.

    Happy New Year !

Thanks a lot for the help. I bought a new Push & Pull cable from Motion Pro because I think Mine are just really old, they're the original ones so I figured putting on new cables can't hurt. They weren't expensive so I'll be putting them on soon. I'll try routing them the way you described. Take it easy guys.
