TT250 clutch cable options
Hi all,
I think my clutch cable might have lost it's tension. It's only a 1000 miles but I commute a lot and put a lot of gear changes through it and I wonder if I just got a weak one. It needed quite a bit of adjustment back to spec (2-3mm according to CSC, same as my Kawi) and in traffic with high engine temps it feels like it's rubber-banding and going further out of adjustment. Netutral is getting very elusive when the engine's hot, because the plates are sticking slightly. I've adjusted when hot (actually at the lights) but I feel I'm chasing a moving target. Are there any third-party cables that fit? I used a Motion Pro replacement on my Ninja and it's great. I'm going to write CSC but I wouldn't mind a heavy-duty option if I can get one. Either that or my clutch plates are knackered, but I baby them so I really hope not. I really think it's the cable as the bike shifts okay and is fine before I get to stop'n'go traffic and I think the cable isn't quite pulling the plates as far as it can when hot. I have tried fresh oil, no difference. |

It's not loose on the lower adjusters??

I don't think so, I've shone a light down there and they look like they are much the same as the factory fit. I may check again though.

From CSC's page https://www.cscmotorcycles.com/TT250...UTCH-s/318.htm (16003 bearing/ 6 bolts...), i guess these works fine...

Trouble is ARH if I set that amount of play, when the lever is against the bar the plates are still a little sticky, whereas I used to be able to hunt for neutral with the lever at about 9/10ths travel. I've no problem changing gear and selecting first gear (although I first realised the cable needed adjusting when the engine stalled selecting first gear). It's possible the plates have started expanding more than normal, but I don't know. The engine's running pretty cool, but the weather's warmer. Maybe all that cold weather riding just spoilt me. I'm not sure but I think slightly warped plates might do this, I'm hoping it's not that, but I guess I'll know soon enough. |

I changed it to Rotella T 15W40 (non-synthetic) just to see if it made any difference but it was much the same once the bike was up to temp. Rain here for the next two days, next job is to re-rig the clutch cable to normal spec (It's adjusted only at the perch at the moment) and tighten the chain which has slackened a lot since install. I've known inertia from a slack chain do funny things to shifting before, perhaps it will yield a result. |

On my Hawk I have found that the clutch cable requires far less free play to function properly than spec., like almost zero. Try it with just a hint of free play...
Specification and china bike lol...with spec free play in the cable, the clutch lever is simply not fully disengaging the clutch...tighten the cable! |

Actually if I did end up having to change the clutch it doesn't look too horrible a job on this bike.
My guess is if it's not the cable there's a chance I've just got some bad plates, and they've got worse. I'll need to have it sorted before summer, because it's not even hot at the moment. |

Having ridden back from work I think newer cable may help, but I seem to have the same bike a lot of people talk about now; I have to blip the throttle slightly to pop the bike into neutral, which isn't awful.
Replacement plates are cheap, even the whole assembly is quite reasonable, perhaps I should just see if a fresh cable helps, it's not like they're expensive. I can probably live with it as it is, but it was much nicer before. I hate holding the bike in gear and normally compulsively drop into neutral if I have to wait more than a couple of seconds. I need to get the driver for the nut on the oil cleaner before being able to take anything apart (and a replacement gasket) but I'm increasingly curious about the condition of the parts. Nothing should be worn at 1000 miles of street riding, but it's always possible something's started to go prematurely. |
