    Post Mods thread: Hyosung GT250R

    **UPDATE! So you've found my thread! Good job - well before you get too into it let me stop you right there. "Evey" as she's called - has been binned. Pretty hard too. Scenic Drive (auckland) chewed her up real bad so the 'Mod' thread is about to be replaced with a re-build thread. The main reason to read this thread is for info on modding your Hyosung CDI unit for better response / eliminating the famous 3'rd gear flatspot..**

    This thread is all about my sexy GT250R, or at least it will be - I'm starting to customise it now that I've hit 8,000k without the slightest problem. So here's a list of what I've done so far and what needs doing. I'll update as I go.

    What I want is any advice other bikers, particularly any Hyobag owners might have on these:


    Mod 0: New tyres. After a 160kph double blow out (it's ok, i threw myself into the road and caught the bike with my crotch) :P I replaced the shitkos with some GT501 Radials. Great tyre. DONE!

    First mod: loose that can! I've picked up a Screaming Demon straight-through pipe from aussie, in comes in shiny carbonfibre finish and should give the bike some roar. DONE!

    Second: New air filter. BMC make a top-quality air filter for the hyosung so I'll chuck one of those in to help out with the inflow (since outflow is already sorted). PENDING! (waiting on parts)

    Third: Get that bitch rejetted! She'll be running lean as a kenyan with the new filter & can so i'll get the boys at Red Baron to fiddle with her bits till she's puring. Otherwise I imagine that she'll start hurting - fast. PENDING 8000k SERVICE!

    Fourth: Bling her out. New high-wattage head lights, clear-style indicators (2008 hyosung ones, fuck this microindicatorcrap - i like em CHUNKY!), Gold anodised tire valve caps & gear/clutch levers, and some custom decals on the front fairings. LIGHTS DONE - INDICATORS DONE

    Five: Speedo healer. I know the speedo's out, but the question is - by how much? I'll pick on of these up and slap it in. Just hope it's easy to wire.

    Six: Fit a (fake) alarm. Who the fuck wants to steal a Hyobag? I don't know, and frankly I don't like using an alarm anyway - I've got a disc lock, and a baseball bat. That's enough for me. So i'll wire up a flashing led to the dashboard. That should do the trick.

    Seven: Custom seat cover. I met a guy, who knows a guy who's dog does upholstery. Hopefully I can rip the pleather off my seat, put some nice 'soft' foam in their and get it sewn up for $200 to $400 less than the $300-$500 odd bucks everyone else wants for the pleasure of doing it.

    Eight: Tail hugger & Tail tidy unit. Rip off the shovel on the back of the bike and enjoy all the road shit leaving a stripe up my back. Then get a tail hugger installed along with chain guard to match - for ideas see Warlock's GT250R.

    Nine: Braided brake lines along with scintered pads. 0-100 is good, but I think the faster I can get the back to zero again is more important. New brakelines and pads are the last part of the plan.

    Ten: Enjoy!

    So. That's the plan, in no particular order - just as I can afford it. Any thoughts comments or gifts of money?

    You know, all that mod is like x-mas presents for your family & relatives for the next 5 years.

    Ah, why don't you just buy another bike with it all kitted out?

    But never the less, if you head up my alley there's certainly a cold one waiting for you.

    Just one question, how on earth do you get your bike up to 160 km/h ?
    I can't get more than 130 km/h out of mine (naked, full throttle, chest on the tank in top gear). Is my bike rooted or am I too fat (75kg) ?

    I'm also on the naked, and I can reach 140 on a long straight.
    I never even get down that low and I weigh 95kg.
    Maybe you're changing to 5th too early...it's more of an overdrive gear

    Lying down flat on my tank and only weighing 68kgs the best I have managed is 158kms. However mine is the GTR and the speedo is out by about 10%. Probably could do better with a longer straight and a tail wind.

    I'm going to make mine stop faster rather than make it faster over-all. Braided lines and better pads.
    While you sit there liking things just cos' everyone else does, I'll be standing up here keeping it real.

    That's a good list.

    I've already added the extra front brake, and the SD exhaust.

    Next I wanted the hugger and a belly pan.....just for the look.
    Plus a fender eliminator...but not that one you can buy...the indicators look a bit suspect legality wise...this seemed like a good idea tho
    http://www.korider.com/forum/modules...ewtopic&t=5812

    Some braided brake lines...with matching yellow PVC outer

    Some new tyres...but only once the shinkos wear out..they're doing ok for now...and get some shiny new valves...hopefully like this
    http://www.cycletreads.co.nz/content...l&entryPK=2337

    Then some clipons, gel grips, and some way of attaching the mirrors

    Then a digital speedo unit

    And lastly replace the single front bulb with a dual bulb setup.

    Whether I get any of this done before I think about upgrading is another question.

    It finishes way too soon, like me. But truth be told, my balls top out well before then Its too exiting. But If I was to mod I wouldn't say no to a RG500 engine!

    I'm just glad I didn't get one of those naked bikes commuters - too boring.

    Thats well worth thinking about. I dont know how long till you can get your full but there dont seem much point sinking thousands of dollars into a bike when it dont increase its value at all and you plan on selling it in the short/medium future anyway

    There is nothing wrong with the shinkos. I have done over 10000k's on mine and havn't had any problems. I think in alot of occasions people like to blame the tyres instead of their riding abilities.

    Also the Shinkos are rated to 210k's which, even with all those go-fast parts it'll have trouble reaching

    160kph? Easy.

    First I'm light, low sixties kg wise, second - I had a good straight to blat on, third - the bikes faired, third - It didn't really have a double blowout, just a nasty puncture and skid but kept her up.

    And assuming the speedo is 10kph out at 150 - I could still get mine up to 170-180 with the right conditions, exhaust and airfilter etc...
