Hyosung servicing

[Dodger]

My 2006 GT250 has been serviced every 4000k's by TSS(redbaron) in LH. (now on 29000ks)

Due to cost, I'm thinking from no on I'll just take it in every 10000ks and just do the basic oil change myself every 4000ks

[DarkLord]

Do they do much to the bike after it's done that many K's, dodger? is there much that needs replacing?

The guy at Spectrum thinks that the Hyosungs are pretty reliable in regards to engine components and as long as you keep up to date with the oil and filter changes and keep an eye on the chain and brake pads, you won't really need to do much to it at all.

[Dodger]

So far I've had the following replaced at services.

Both Tires (rear at 15k, front at 28k)
Chain and sprocket (20k-ish)
Pads front and back.

gw555 is the true expert as he's over the 60k mark now and his bike is only a month older than mine.

I also had a few bits replaced in the first 5000ks that were covered under warranty.

Dodger not sure about the expert bit BUT I have clocked 77000 this morning

Okay I have had mine serviced 20 times now and only 3 times has it been over $400.00 (excluding tyres). All serviced by TSS in Lower Hutt

The main things are the valve clearances which have been checked every 12000 and been adjusted once

I should add the only reason for the >400 was things like new chain and sprockets, plugs and pads all put in at same time.

Good to hear. My valves could probably do with a clearance now as well as mine's done about 30,000 k's.

What exactly is a valve clearance? (Noob question I know but hey you don't ask you never know) Does this take long to do and I don't suppose it's a DIY type job?

Its not really a DIY job, unless the covers are easy to get at and remove, and the clearances are just a simple screwdriver and ring spanner job. I've never seen the lid off a hyo motor so I dont know. I might pull my cover off sometime just for a nosey. edit: The GT650R has shims and no adjusters, so unless you have a good selection of shims and lots of time and experience, its a workshop job.

There is a rotating actuator above each valve and these require a tweak now and then to make sure they are close to tolerance. The valves will make a tick-tick-ticker noise if one is a a little loose, and they will leak and damage themselves if one is a bit tight.

It is the inlet and exhaust valves. No its not a DIY job (although somebody will disagree) When mine were done and the exhaust reshimmed it made up most of the $414.00 bill that I got (about $250.00 looking at the invoice) The bike had done 48000 when this was done

Thanks GW,

Was that the first time you had it done? I'm thinking the longer I can put it off for the better as I just had to replace the front brake pads as well as spend $$$ on an oil and filter change.

20k for chains and sprockets!!
Bugger...I got told mine needed replacing after 8k. (by Red Baron during a warrant)
Ended up going to Cycletreads, who said nah...just do the chain.

I thought 8k seemed like it was a bit to quick, but then I was a n00b who probably hadn't been taking care of things properly.
Oh and Red Baron wanted to replace them with original hyosung parts too...which seemed very expensive, and were probably not the greatest quality

[tri boy]

Hyosungs use under bucket shims. Cam shafts out to swap to the right thickness.
Cam timing can easily be set incorrectly, as the tensioners need to be backed off, and the chain can skip one or two teeth on the cranksprocket.
Checking the clearance is quite straight forward, but it pays to have someone there who knows a bit about this stuff.
Leave the shim exchange to the pro's. (you won't have the shims anyway, and shops charge for exchange, and if you choose the wrong thickness you will have to pull the cams again, and ducks fly backwards in spring, and fish breath through..................
ya get the picture?
oh,clearances are IN 0.004-0.008", and EX 0.008-0.012". (I will let you convert to metric).

If it was me I think I would get them checked nice and expensive if something goes wrong.

If the clearances are okay I was charged around $100.00 for checking them

Mine have been checked every 12000km so by the time they were reshimmed they had been checked 4 times

Anybody know anywhere in Auckland that does valve clearances and how much I'd be looking at?

[Dodger]

I did have a chain replaced at 5k under warrenty, as it was faulty from day one. (felt a tapping on the left foot peg at times)
The replacement lasted me untill around the 20k mark (maybe 23k), and was replaced at my second WOF.

Nice!

I'll be at 32000 by the time I return from the Burt Rally in Invercargill in a few weeks, but doubt I will ever catch up with your milage, although my last 15000 or so has been ridden 2-up
