Replacing throttle cables - throttle bodies stuck !

[kramdra]

CBR600F 2003 with 80,000 miles, everything under the tank coated in an inch of farm shit from my daily commute.

How remove the throttle bodies? or is there some way to get the cables off/in without? old cable was starting to fray at grip end. I have cut them off so it is not possible to give up and continue use.

I have been trying to remove the lower joint between rubbers and engine, rather than rubbers and TB. Which should be easier?

About to try spraying hot water to heat the rubbers and get more flexibility.

Thanks

Usually easiest to pull the TB's off the rubbers. If you can get the clips right off you might be able to break the bond using a pair of large pump pliers by gripping over the connection and very slightly twisting the rubber but you have to be uber-careful not to tear it. Usually I just grab the throttle bodies and 'hinge' them up and down a few times to crack the bond.

IIRC, I've replaced the cables on the same bike without removing the TB's, I remember it being a ball ache but I got it done.
If you have to remove 'em, do as Pete says, alternatively, if you're feeling brave, what I did to get the rubbers off, when I replaced mine, was pushed a thin blade screw driver down the side of the TB's and rubbers and worked them loose as best I could.
When I got them off, which wasn't a quick job, they hadn't been damaged and could have been used again, had I not had new ones to fit!
But that method's always going to be a gamble!

When you get the new cables fitted, make sure they're routed correctly under the front of the tank, it's very easy to trap the cables, on the frame just behind the headstock!

Bar of wood levered between side tb and frame. Popped off easy. Only pot4 intake was open. Piston and bore look clean but it does have some scoring. 2 and 3 had some fresh dirt sitting on the valves ready to go in. Will get my usb bore scope out next time for proper look
