God Bless Suzuki.

I've not actually heard of any others braking.

Mine had a clutch mod early on cos the clutch was grabbing, and, I
thought Molly had the same mod done around the same time.

 

Christ. Well, I reckon an engine out, strip, rebuild and re-fit job
should be 20 hours at most, which means 50 quid an hour, inc VAT.
Which is a fucking lot, imo.

 

Same problem as Sorby had with his 750 isn't it? And I've seen a few
on the forums.

Must get mine done.

 

Must be that new-fangled slipper clutch like on the GP bikes.

 

What are they, anyway?

 

(William Grainger) somehow managed to post:

Comfortable, tartan clutches, used by old bikers, in conjunction with
titanium pipes.

 

Clutches that reduce engine braking, or summat.

 

Wow, my first compliment.

 

They won't admit to it in public though. I've spoken to some race
teams who run Gixxer Thous, one of the first things they do is replace
the basket.

 

What, slipper clutches?

Well, you know that engine braking thing? Well, turns out it's apain
in the arse at racing speeds. If the back wheel is off the ground (or
nearly so), you don't want the engine trying to slow it down,
especially with the sky high compression ratios the MotoGP bikes are
using (there's a reason they don't bump start them anymore, but use
starting rollers).

So, them clever engineers have been trying all sorts of ways to stop
the braking forces generated by the engine being transferred to the
rear wheel. A "slipper clutch" is one such way - the clutch slips
when loaded in reverse.

<smug>
Of course, ZXR 750s/ZX7Rs have always had them.

 

do you mean on or off the ground here?

Hardly new thou, are they?

Clearly not.

Do I remember some big road going bikes (ie not race-reps) having
them to prevent the wheel locking up on ham-fisted (ie not perfect)
gear changes? Or did I dream it?

 

I did. But there was a problem with the 750 clutch baskets and it
seems [1] to have carried over to the very early K1's.. I assume that
this was one of the reasons why race teams changed the clutch basket.

[1] Based on what my dealer told me.

 

I did check with my solicitor and she was a little surprised at the
offer considering it was out of warranty.

I've a feeling that if I push it I will start to get caught up in a
legal wrangle and my poor bike will be left untouched for a while.
After all, I'm getting what amounts to a few grand worth of parts [1]

TBH, I'm taking the money and running. After it's fixed I will try to
recover some costs.

[1] Workshop manager reckons about 2.5K retail. [2]
[2] I forgot about the new oil pump as well.

 

TBH, I don't think you're far out. I'm assuming about a grand inc
fluids and VAT.

 

This is basically what my solicitor and hte workshop manger told me.

TBH, I'm pleased.

now try a solicitor with experience in consumer law.

Fair enough if you need the bike running and are prepared to pay a grand
plus to have it fixed. I doubt you'll see a penny after it's up and
running though.

I was watching some consumer prog on TV the other night. Land Rover have
a problem with 2.5 TDi engines losing the drive to the oil pump because
a bolt is undoing itself, resulting in engine failure. Alot of it is
happening out of warranty. You're looking at the thick end of 6 grand
for a replacement engine if it happens.

Apparently it is down to a manufacturing fault from new. Some consumer
expert was saying that if a bolt fails because it was unfit for the job
when it was fitted at the factory, then the manufacturer is liable for
repairs or replacement of the engine unit for up to 6 years, regardless
of the length of the warranty period

 

Not the point, surely. You should be entitled to a reasonable life
expectancy of the part, whether the part is classed as a "consumable" or
not.

I would say 6 months is a touch unreasonable for brake disks [1].


[1] Given standard use obviously.

 

Yes, but not on a 8k mile, 6 month old bike.

 

Champ says...

My 1982 VF750Fs had slipper clutches too. Made a fucking /awful/ noise
when you changed down to 2nd at 110mph and dumped the clutch, but the
rear wheel never locked.
