Oh, Mr Hyosung, you so craaaazy

[Rogerborg]

So we piled into chumrade's GT125R today mob handed. It turns out that it had one of the ACME E-Z-Corrode swing arms, so a new one had been obtained and needed dropped in. But to get the swing arm off, the exhaust (I was assured, since I turned up late) had to come off. Weird, but there we go, shouldn't take... aaah.

Well, OK, that's the rear pipe off, but the front was solid in the head and oops, there goes a stud. After some tugging and twisting, double oops, that's us got two bits of exhaust. While Team A drilled and chiselled the seized remains of what appeared to be anti-tamper bolts off of the pipe-to-can join, Team B wrestled with the stub of the exhaust in the head. Would it come out? Would it buggery.

Anyway, Tef-story-short, three hours later we have a box of bolts - including the bonus secret hidden ones holding the head and barrel on - and the front cylinder head off, with only one exhaust stud snapped off short. After some extended drilling, cutting and eventually HULK SMASH chiselling, the pipe collar eventually gave up the struggle, taking a (hopefully non fatal) chunk of the head with it when it went.

Break for tea, ordering new exhaust pipes, and taking the head away to rebuild with chemical metal, and drilling and tapping for a new stud.

And all that to change the swing arm on a 125.

I'd like the meet the chap who designed this bike and shake him warmly by the throat. It almost feels as though hostility is engineered right into it.

Much in the way of expletives uttered?

Maybe the exhaust is designed to be the backup swingarm when the first rots away?

Its always fun when a simple maintenance job turns into a mammoth task with bits failing left right and centre following their disturbance!

Of course you did spray the bolts generously with a penetrating lubricant and leave for a few hours before attempting to loosen didn't you.
I mean common sense wouldn't allow you to do otherwise.

Perhaps it is not crazy at all. Perhaps it is part of Hyosung's long term sustainability. I mean, look how modern cars and bikes are now. Plug and play, can't do anything but the most basic of maintenance of work without having all the rizzle-shizzle of computer plug 'n' play goodness.

Hyosung don't have that much ability yet, so they make it so the noob's who it is aimed at can't work on the bike unless they have a bit of nous. What better way to keep mechanics in business?

Rog, dude.... no pics?

[pits]

Why didn't you get a blow torch out and heat the head/studs/bolts up? These days it is the first thing I do before going near exhaust studs and nuts, been there done that with VW's

Cheers, we'll give them a try. I think it's going to be a telephone search - I'd just got so used to being able to type and click and have stuff turn up.

To get the swing arm out the SV the exhaust had to come off. The rear downpipe goes through the swingarm just aft of the pivot, then bends itself silly to join onto the front downpipe and into the 1 silencer.
I know the hyo GT650 is practically an SV engine, so I wonder if the 125 takes any similar design fetures, also being a twin and all that.

You'd do well to avoid them.
