    Years ago, (read 70's-80's), the Japanese issued flat rate manuals to dealers so they could submit their own labour rate using codes to enter on the warranty form.
    As far as I know, this has died out, and franchises are at the mercy of the factory with regards to labour cost recovery.
    Sometimes you work out a shortcut to the factory recall method, but 90% of the time, you lose out, as paper work etc eats into time.
    I'm still waiting to meet a m/cycle shop owner that lives the rich life.

    I had a leaky vacuum fuel tap on my 650 at about 15,000km - new kit to go in it, no charge.

    This is only for the 07 GT/GTR and not for all 07 models either some of them dont need it (earlier 07 models I believe) for instance our 07 comet didnt require it.

    Interesting about the fuel tap my wife's 250 comet just required the same part but its only $10 or something so no big deal.

    Taken from Korider:

    This thread is just to inform you that there's a recall here about a problem found in the camchain tensioners in the models: GT250, GT250R, GT125 and GT125R (also fuel injected models are affected) bought during 2007 and beyond.

    The problem causes strange engine noises and the possibility of it to blow. The dealers by now are being informed and they're slowly replacing those defective camchain tensioners under warranty. They have made public a list of affected VIN numbers, but there's evidence that there are many others affected too.

    This is the list:

    QuoteLast 7 VIN numbers for 125s:
    from 1500041 to 1500713
    and for 250s:
    from 1500001 to 1500881



    An important note: a dealer informed one mate of the Spanish forum that the defective camchain tensioners can be easily identified by finding the part in the right side of the engine and comparing it's size to a normal one.


    Note 2: seems that GV models could be affected too...

    Thread dredge......

    A mates GV250 has seized for no apparent reason. They are big on servicing so it didnt run out of oil. And its done under 20000k. Did the cam chain issue cause many seizers?

    Another quick question, does anybody know if all Hyo 250s have the same motor? Will a GT250r motor fit a GV250?

    Yup.

    It's funny. I just sold a guy a GT650 who's had an 06 GV250 since new, commutes every single day and has does 104000km. Zero (no shit) issues although it's got a bit of a rattle now. Sold another guy a 1250 Bandit, he's commuted every day 2 up on his 2006 GT250, done 78000km. Greg Wilkinson's GT250 has been featured in KiwiRider. 130,000km + on his of fully loaded turing. Admittedly he's had a top end rebuild. He jsut sold it for $2K

    And yet Hyosung get a bad rap for being unreliable? Strange........

    If it drops a camchain it will seize the engine for sure, and probably destroy itself in the process.

    An important service item on these, is to lube up the tensioners so they operate freely. Simply remove the little cap and fill them with engine oil - maybe give the tensioner a little spin to make sure its not stuck.

    Will be checking that was done in its last service. Had one about 500k ago. Will be going to dealership where it is tomorrow.

    Im sure that most are fine or the brand would be dead. But it would seem some have catastrophic failure. So if this particular bike missed this recall then that is a possibility of being the cause of this failure.

    Ive known this bike for some time and the owner is big on servicing. It goes to dealerships for this. The bike has done 17000k. Its not been thrashed.

    Im interested in the root cause.

    Went and saw it today. Rockercovers were off. It not in the top end. Mechanic seems to be correct. Its done a main or big end bearing.

    Its rooted. Quote of 2k to fix.

    Bit rough an well serviced bike with 17000k on it.
