Right, second attempt as my first post disappeared!

Over the past few weeks, gearshifts have gotten increasingly bad, and the past couple of days have been a bit of a pain!

1st to 2nd - Spongy, feels like there's too much travel in the shifter, feels like it's just gone into gear.

3rd to 4th - Same as above. Higher revs makes things worse.

5th to 6th - No major issues. A little off, and could possibly be getting worse.

Could this be down to old rubber bushes in the link cables. It's odd that it's only on the downward pulls on the lever that it feels awful. I'm hoping it's not the synchros!

Any ideas? Is this a common thing 'round these parts?

When did you last refresh the gearbox oil, clutch fluid?
Gearbox oil, about six months ago. Clutch fluid seems clean and of a decent level, so never.

It feels more mechanical. Any guides around here for clutch bleeding? I may look into the cheapest option first this weekend!

It may feel like the linkages because the hydraulics aren't up to scratch.

Brake fluid deteriorates over time so in our humid climate it should be replaced every 3 years or so.

Bleeding can be a PITA but can help a great deal. Good luck.

Where's your biting point?

The biting point when I got the car was so low, I had to adjust the thread above the pedal to get it further from the floor. If I run a test now and it's higher than expected, would you recommend bleeding the system through?

It always felt very mechanical, but shifting now, that's gone, it's like stirring thick mud, with no defined stop to the lever travel!

As you don't know when it was last bled, if i were you then I'd bleed it and then reset the bite point.

With any luck this will cure your problem.

If not, then at least you know that you clutch fluid is good for a few more years.

The same applies to brake fluid too ;)

Brake fluid is all new. I replaced the front calipers last summer and purged the entire system.

Silly question, but brake & clutch fluid, same stuff? Dot 4?

Yup dot 4 all the way (clutch and brakes)
Awesome, Not sure how much fluid a clutch takes (or even where to bleed from, but that's another matter!). I'll grab 2 litres and properly flush it through and get the old stuff disposed of somewhere safe. Getting the undertray off is the biggest issue. Mines completely cable-tied on for maximum JDM!

I'm hoping it's not as much of a pain as my '91 GSX-R1100......now that's awkward to get all the air out if you don't top the reservoir up in time whilst pumping!

Sounds like a clutch on it's way out
That wouldn't be the worst thing possible. It's got to go sometime. Maybe 62,000 miles is enough. Not sure if it's ever been changed!

The clutch takes 500ml to flush, a liter will be plenty.

Removing the undertray is one option, out with the battery and tray to gain access from above is another.

Bleed via the slave cylinder on the front of the housing.

Right, I've had the airbox out this morning to have a look at the shift cables, and one in particular is utterly ruined! On the downward pull on the lever, it's totally slack. The lever is now hitting the stop to get it into gear. I wanted to wash the car today, but I'm saving the limited life left in the existing cables, to get it to the garage once parts arrive!

I'll be replacing them with something a little more substantial. Genuine replacements are £406, so I was thinking of going a little higher and getting something really nice. Has anyone had any experience with these?

The description talks about Integra fitment, but there are many models listed below, including FN2. If I'm going to stick £400+ on the card, I may as well fit something with a decent build quality and warranty. It fits with my desire that, when replacing broken stuff, I'll fit something slightly better each time!

This is an odd one - not seen this before.
Surely these cables should last a bit longer than 62k unless someone has damaged them somehow?

On the downward movement of the lever, it's totally slack/kinking, and is no longer covered with the rubber boot.

I have heard from a few places that the cables can be a bit 'tetchy', but those complaints were more about rubber bushes. At this point, I'm just looking at something broken, and trying to find a better alternative.

At 62k miles, I'm expecting a few things on the car to start dying/wearing out. It's just the way it is, nothing lasts forever. Rear calipers will be replaced in the summer, along with discs and pads all-round. I was hoping to get my bike back on the road this year, but it looks like it's car time again. Oh well, a '91 Gixxer 1100 will always be a part-time toy, the car is way more important. I've been very kindly lent a 100k miles MG TF to see me through, but I have to admit, I'm not overly keen! I want my FN2 back!

Over the last few days i have noticed a clunking type sound when changing the downward gears only although gear changes are still smooth. Car done 38k miles and clutch and transmission fluid changed over the past 12 months

Engine mount or driveshaft maybe?
Yes that's what loxy thinks. No urgency so will get it looked at in a few weeks. Cheers mate

Update.

I ordered a new set of shift cables, which arrived on Wednesday. I was going to buy a set of aftermarket ones from H-Tune, but the shipping was going to be a month. I had a nice chat with them and they said the standard ones would be fine. They were fitted today, and the car is transformed. They must have been going for a while, as every gear change feels totally slick now, with everything slotting in beautifully.

Genuine parts and garage labour costs have meant that this wasn't a cheap fix (I can't buy my lovely new set of Tannoy floorstanders for a while now!). But I like the car. It's shiny, has fairly low mileage, and drives brilliantly, so it's worth it. I don't want to cut any corners here!

Well done fixing your issue

It's not a common issue but may become one as the cars clock up more miles/years.
