Mods thread: Hyosung GT250R

[xwhatsit]

Well, as you've listed the jet sizes, no need to pay $90. Simply work out what type of jets you need (what brand carb? Keihin? Long hex-head jets or small hat-style?), and order the appropriate jets from your local dealer. I payed $7 for a single hat-style Keihin main jet. $90 is quite a mark-up on $14.

Save every last cent you would use to mod your 250 and spend it on a bigger and better bike later. That way you will get a hell of a lot more bang for your buck. I expect I will keep my 250 bone stock.

Did you ever notice that people shopping for used bikes prefer a clean stock one that has been maintained by the book to a blinged out version?

Not everyone intends on getting rid of their 250 once they get their full license.

[Vetran]

Also if you were really worried about saving money for your next bike, you would not by a new one, as it will depreciate far more than a used bike.

spoken like a true scaredy cat

just kidding, im keeping mine too

[Gubb]

Plan is to keep the Hyo as a commuter. $25 for 350K's? Can't go wrong.

The other bike shall (A Speed Triple - one day...) come out at the weekends.....

I want to get a R6 as soon as I get my full. I don't know weather I'd sell my Hyosung, depends on what its worth when the time comes.

If I didnt wish I could be nimble, then I'd see no need to upgrade.

That's exactly what I did - only a little neater. Didn't actually 'Cut" the wire, just removed it from the plug and insulated it. If anyone wants to do this but is worried about getting the wrong wire try this:


Hyosung GT250/R 2006/7 (NZ new imports)
1. Open up the seat.
2. Un bolt the CDI unit. (small black brick next to the relays)
3. Disconnect the Brown plug from the CDI. BE GENTLE.
4. Get a very small Alan key - preferably one that will fit into on of the circular holes in the 'male' end of the brown plug.
5. Locate the Green/Blue wire.
6. This wire should be in the same position as in Pancakes photo - if it is in a different position DO NOT REMOVE.
7. Use the alan key to carefuly push the copper contact out of the plug. It should pop out the other side with the wire, blue plastic bung, and copper contact all in perfect condition.
8. Tape up the end of end of the copper contact VERY thoughly with electrical tape. If you have some kind of plastic insulation to cover it as well I suggest using that.
9. Tuck the loose wire back into the loom.
10. Reattach the CDI.
11. Power up the bike but DONT start it. Check all your lights work, and check the digital dash if you have one.
12. If everything works fine continue - if anything has stop working then stop here - you've fucked up.
13. Fire up the bike. Let it idle. Listen for anything odd - firing on one cylinder etc... normal? Good!
14. Test the kill switch. If it doesn't work, you fucked up.
15. Everything works go ride the bike. You should notice a VERY smooth power curve now.

Dunno if this has already been asked, cant b f'd reading it all. But does this work for The GT250???

[Weaver]

.... I would imagine so....you could try and let us know, then when the next GT owner asks we will have a definate answer.

[Gubb]

Yes it does, exactly the same engine and electrics.

Worked VERY well for me Its a non-permanent fix, so you can always plug the cable back in if you arent happy.

Give it a try, I was happy. No more 5000-6000k flat spot and much smoother shifting.

EDIT: Oops, just realised I didnt answer your question at all.

[nivram]

I have a GT Comet 2007 and it fixed the flat spot problem for me.

True that, i'll never sell my rs. There are afew others on here that are the same (with there rs's n rgv's neway)

Considering your mods have cost less than $500 id say its well worth it! Rode a mates stock hyo and was not impressed, but did get the feeling it wouldnt take much to make it noticobly better. Would be really interested to see what a moded one feels like compared to the stock one i rode.
Congrats

Bling your way for the clever moding and the help your giving, well done keep up the good work
