Servicing time can eat into riding time and so sometimes we’re choosy about just which tasks to perform. Personally, I’m right on top of washing the bike, cleaning air filters and changing oil.
But lubricating cables? I do it a bit, but know plenty of blokes who only do it if they have to, such as when the ’stupid bloody thing’ is seized and won’t work due to lack of lovin’.
It’s actually only a five minute job and can not only save you dollars, but make the bike nicer to ride.
Most of you know that I love to use the clutch to improve my riding, so a smooth and easy to use clutch lever is a must. A clutch cable and/or perch that is clogged with crud makes the lever harder to pull in, which can be a major cause of arm pump.
Throttle control is also vital, also being much easier with a smooth set of throttle cables.
So, let’s begin with a dirty specimen. No, not the one from Bindaree Falls, for those who made the Buller trip, but the dirty cable on my 450X.
Remove the lever and cable from the perch. Firstly, take out the bolt that holds the lever to the perch. You might need another spanner to hold the lock nut on the bottom end of the bolt.
Adjust the quick adjust cable adjuster on the perch so that you have as much free play as possible. Then remove the lever from the end of the cable.
Then line up the slot in the quick adjuster screw with the slot in the perch and take the cable out. You need to pull the cable through both the rubber cover and the rubber quick adjuster. Both should be cleaned out with a rag for the best job. Then you’re left just with a cable.
All this crud on all these components works to create more friction and wear, neither of which we want.
So, to clean the cable, firstly use a rag to wipe the crap off the bit you can see. Then we take our ten dollar cable - luber, available from all good Honda shops (Ed: rumour has it that Yamaha actually make a really good two - bolt model, but I can’t tell you that) and affix it to the cable.
Then, use something like Contact cleaner or Castrol DWF (De - Watering - Fluid) to blast the crap out of the cable.
Contact cleaner is probably the best, as it leaves no residue, however it’s fairly pricey. It is also ace for cleaning the crud off the lever and perch, but there are certainly cheaper options involving more labour and perhaps a rag. Good luck with that.
Most times, I use a rag to cover the cable luber, as dirty wet grime tends to spray all over the joint. Cable - lubers tend to leake a little where the cable comes out the top end.
How long do you spray for? Until all the crud is gone! Check the other end of the cable and when dirty discharge has been replaced by clean discharge, you should stop, as after this you’re just wasting fluid.
If you’re pedantic (Ed: I don’t like the word anal much), you might want to stick a rag under this end to catch the crud.
Then, I replace the Contact cleaner with a can of graphite spray, which I find works really well. You only need to spray a little, just enough for some to start weeping out the other end of the cable. You’ll know when it does, the ooze will return to graphite - black.
Now you can re - assemble all the bits. Feed the cable back thru the rubber adjuster and cover, then onto the perch via the slot. Attach the newly - cleaner lever. You can use a little light grease on the end of the cable where it connects to the lever, the lever where it rubs on the perch and the bolt that attaches the lever to the perch, but only a very little or it will attract crud.
Re adjust your lever free - play so that you’ve got a little free play, go and put your riding gear on and enjoy the thing.
I think that whilst hydraulic clutches certainly have some advantages, particularly in that they self adjust and are often nice and light at clutch pull time, they are not as reliable as the old cable and perhaps thus less suited to trail use.
We’ve had a couple get some water into the fluid on recent tours and either not work at all or take a fair bit of work to get going again. Note that they take mineral oil not brake fluid, as brake fluid eats into the rubbers.
Lubing your throttle cables is very similar to the above, excepting that you need a little more patience sometimes to get the throttle and cables back together. You also can’t see the other end of the cables, as they are hidden under a plastic cover on the right hand side of the FCR carby.
Suffice it to say that the crud spewing out the other end of the cable when you blast contact cleaner down it does not enter your carby, but will just ooze into the void under the plastic cover, causing no real issues.
When re - assembling the throttle, some graphite spray or 5 WT fork oil (Ed: or Auto Transmission Fluid, which is just like fork oil) works well to lubricate between the newly - cleaned throttle tube and the handlebar.
Beware, don’t put too much force into the 6mm bolts that hold the throttle cover together, they can strip out fairly easily.
