Grrrr!, now the throttle cable!
Sorted my clutch cable out, with help from you guys on a previous thread. Took it for a test drive and the world was once again a great place to
be.....................................until the throttle cable snapped!
I can see the funny side but I hope this isn't a sign of things to come!
Any tips on changing the cable on a '98 blade engine?
Plus any jokes that might put a smile on my face in the meantime?

I would take the carbs off to make it a thousand times easier if it were me...

which end did it break....mine broke couple of weeks ago (919 blade) at the pedal end....easy fix..MK had the cable for mine although my problem was
the attachment at the pedal end which caused the break...all sorted and running fine.....if it is the pedal end you may have to remove the bulkhead
panel to make repair real easy...good luck, Andy

Yep, pedal end. I've got a cable on the way which I'm going to connect to the pedal end then cut down to suit the engine side of things.
Bit reluctant to use the existing cable as after 2 cable failures in a week I think I'm best off replacing it full stop.
Was hoping I wouldn't have to remove the carbs etc but I'll have a proper look later and see if I need to as I'm going to remove the
old cable. Is it just a case of removing the carbs and replacing them? Presuming it's not as simple as a couple of bolts?

i'm not sure but Steve (worx) is the better person to advise as i was lucky coz when i got to the pedal i found the cable had been held in slot
that had been cut in the pedal which with use over time cut the end off. I ended up getting a new pedal with a hole drilled in it so it could take the
proper connector which bolted through the pedal correctly. I was able to use the old cable as the end of it fed into the connector with about an inch
of spare so i actually replaced the pedal and cable connector and not the whole cable....hope this will make sense the way i've explained it!!!

You don't have to remove carbs to replace cable. It's a bit fiddly but it is better having them in place...
The reason for the cable breaking at the pedal end is mainly due to misalignment from the clasp/through tube. The cable rubs on the tube, eventually
weakening it... it can also be caused by the clasp being too tight thereby constantly bending the wire at the place where it enters the clasp causing
it to bend with every movement in one specific place, causing work hardening then splitting.
It's a p*ss easy job if the battery tray is quickly removable. You may need a soldering/brazing tool if the 1/4" barrel nipples are the
type you have on the carb end.

I had my clutch and throttle cables snap at the pedal end too.
When I had a closer look I realised it had been caused by two things - 1) there was a sharp edge on the holes in the bulkhead, and 2) I'd
tightened the cable banjos too tight and they weren't rotating like they should.
What this meant was that whenever I pushed a pedal down, the cable was forced downwards onto the sharp edge. Over time it tore through the cable.
I filed off the sharp edges and loosened the banjos a bit and didn't have any more trouble.

Thanks for all the replies guys.
I'm pretty sure it's just age that's eventually killed the cables. They look like they had been on the engine for a good while. My
replacement clutch cable was a lot thicker with a proper pedal attachement and the throttle cable I've ordered will be the same I'm sure.
The pedal stops are in place and do work as they should, I'll be checking for any rough edges etc while I'm at it.
Steve, U2U recieved, with thanks.
I'll have a bash when I get the cable and see how it goes.
'Tis all good fun!

Reason for the breakages is the pedal should hit a stop before the throttle (or clutch) runs out of movement. ie when the gas pedal is hard down you
want the throttle 99% open not 100% and hard against the throttle stop.
One of these things you learn from experience.

Think I'll go to 50% just to make sure.....

All done!
Went out on a test drive and even managed to get back under my own steam for the first time!
Big thanks to everyone with their advice and a special thanks to Steve.
Fingers crossed for some more sunny days so I can make the most of it!
