So, after sometime I have finally got round to fitting the C bars that Steve1959 kindly sent to me (many thanks Steve!). I know the crash pad needs changing as it is a bit tight and doesn't sit right but it fits and everything works as it should.

The only issue I'm finding is finding neutral, I changed the clutch cable (it needed doing regardless of the bars as I was using an emergency fix for a while due to the original snapping), however, over the last couple of days I found it, not difficult, but I need to be really gentle when selecting neutral, it jumps between 1st and 2nd, no other gear selection issues and no false neutrals. Wondering if the cable is just stretching in? Any advice, as always, greatly received.

Anyway, here's a few pics of the C bars in situ.

There should be no jumping between gears, and there is no "stretching in" of the cable. If the appropriate cable length was chosen from OEM stock, if the cable was routed correctly, if the clutch was adjusted following the correct procedure regarding exposed cable length, clutch arm bolt-to-piston contact and hand lever free play, and if the transmission isn't faulty, there should be positive, reliable shifting from the get-go. Shifting into neutral isn't touchy on my moto.

How much free play do you have in the shifter?  Any slop indicates a loose grub screw and will contribute to shifting issues.

As Laitch mentions, you might want to double check how you adjusted the clutch cable.  Correct adjustment is critical to not having clutch and shifting problems.

I replaced the clutch cable in my K100RS on Saturday. The PO had put in a new one so I hadn't done my usual new cable on getting a new K.

His new cable lasted all of 4,000 miles.

When I took the old one out it had a very sharp 90 degree angle in it. The inner had snapped at the angle.

Further checking with my spare RT/LT cables revealed he had installed the longer cable on the RS instead of the shorter RS one. Would have probably worked ok if he had routed it out around the right hand stanchion...but he didn't.

All I did was wedge the pivot arm up and the new cable went in without difficulty and perfectly adjusted. I ended up with the handlebar adjuster in all the way. However its not quite as light as the K100RT and K1100LT that I also use. I am happy with the routing but the other two are BMW cables and this one got a Venhill one.............

You shouldn't have any gear change difficulty. Adjustment and the amount of free play while easy to do are very critical. 

As an aside when I got my K1100LT the clutch was incredibly heavy and again it had been given a new cable by the PO who religiously followed the routing of the old one....but turned out that routing was wrong, new cable and correct routing and it was a treat.

Cheers for the feedback guys, I am happy with the routing of the cable, it is an RS one and OEM, will check the adjustment again in daylight. Just to clarify, there is no difficulty shifting, all the gears select as normal, it's just that rather than finding neutral first time it goes in to 1st or 2nd a bit to easily, as though it's jumping past neutral. It's not a real problem, just need to be a bit light on the boot, never been known for my gentle touch, I was an Artilleryman for 10years!! 

Cheers for the all the advice.

Dave

I must admit that neutral on all my Ks takes only a very gentle touch to find it and easy to go past it. Having 4 to draw from I am regarding this as normal. It does mean very smooth changes from 1st to 2nd.....

Olaf, My bikes are the same way, they just need a very light touch which does help the shift from 1st to 2nd.  That's why I asked about the loose grub screw, that can make it pretty hard to find neutral because the slop makes it hard to judge when you're between the gears.

I have a 90 K100 rs 4v.

How did anyone think the bars were OK.
1) So Getting the Brake lines redone custom.
2) Throttle cable
3) Clutch cable

the rest of the stock parts I have released from their nylon straps and got enough stretch.

am I missing something?

My bars are from an LT am I going to find a problem as I put it back together?

Thanks 

Jake

You will probably need to replace the crash pad, mine fits with the C bars but not properly.

The other thing I have noticed is how cold my fingers are getting!!! I'm not sure if I just don't remember last year or whether it's because my hands are higher above the fairing, wouldn't normally mention it but spent a winter or two in Canada...
