Posted: 10:09 - 04 Sep 2018 Post subject: Sluggish acceleration - clutch cable or something else? |
|
|
Hey folks,
Keeping in mind I haven't been riding long, I think I may have a clutch issue, or it may be something different, or maybe it's totally normal. My bike is a CBR650F with just over 1000 miles.
When I set off from having been parked up, I sometimes find that the bike won't accelerate properly in first gear. If I apply more throttle I get the same power as before, but the bike will suddenly jump forward and start functioning normally.
If I were to guess, I would say the clutch cable could be sticky and the bike could be behaving as if I still have the clutch in, then releasing after a few seconds. Does this sound likely to those of you with more experience?
It doesn't always happen so I can't reproduce the effect to look in to it, and when it does happen I'm usually concentrating 100% on what is going on with other traffic as I bimble forward slowly.
It only happens when I first set off. Never after the first minute or so.
I assume other people have come across this and have some idea what could be happening. If it's the clutch cable then I could try adjusting the tension or cleaning and lubing it. This has been happening on and off since I got the bike. I thought it was my riding at first, but I'm starting to think it's something else. |

check that the cable isn't getting snagged would be the first thing I'd check. What's the slack like at the bar end?
is it like the video below?

We 'tend' to unconsciously operate the front brake on start up, when we first get on the bike and grip the bars.
We tend NOT to subconsciously 'flex' the back brake at start up in the same way.
And, especially if a DAS trained newb taught to drag and slip and do slow-speed maneuvers on the back brake, good chance that you are noticing this on worx car-park, after starting, after move off, after you have first used back brake, and its a bit 'sticky'.
More modern brake pads use stintered metals instead of asbestos. They can 'stick' to discs when parked up... either electroferitic reaction between dissimilar metals of pad and disc (more prone in damp) or pads being 'sticky' when used and up to temp, then cooling like heat-glue.... ish!
Honda floating calipers also notorious for sticky float pins.
Good chance the bike needs a thorough clean and grease, and attension paid to those bits like the caliper mounts, and the rear rod and lever pivots both ends.
BUT also good chance that it IS just that the bike isn't warm and oils still thick, and like brake-pads/discs, clutch-plates are still are a tad glued together until the bikes properly warm and oil thinned, and the plates are up to temp and un-gummed by a bit of work.
Cable? Is a potential in there, and is oft over-looked both for clean/lube/adjust... but one of many possible suspects, and not necessarily top of the list.
Do some basic maintenance; beyond an oil change.
Watch your start-up/warm-up procedure.. and DO flex brakes doing the 'pre-ride-checks' you were taught on CBT.
See how it goes. ____________________ My Webby'Tef's-tQ, loads of stuff about my bikes, my Land-Rovers, and the stuff I do with them!
