Hyosung GT250R jetkit for carbie????? any help

[Qman]

I was talking to the guys at Mt Eden about it, they ot sure but said if it didnt clear itself up by the next service they would replace the CDI and see if it helped. It was one of the Wellington GTR boys who was talking about replacing the CDI.

"The principal advantage of a CDI system is the ability to present a superior spark to the air/fuel mixture inside the combustion chamber, thus maximizing burn efficiency. The easiest way to get a bigger spark is to increase the spark plug gap size. However, increasing the gap distance also increases the voltage necessary to ionize the air/fuel mixture. And the resistance of the air/fuel mixture increases as the mixture is pressurized in the cylinder, requiring even higher voltage to spark across a plug. A CDI system provides the higher voltage required by the increased spark plug gap size, thus providing very intense spark"

coolo thats what a CDI does thanks for the info I'll mention the issue when I take it in for the first service,

I doubt you guys would of, but have any of you noticed that the spark plugs don't enjoy being held around the 140kmp/h mark for too long?

I've been considering upgrading the spark plugs to the ones which withstand a higher heat temprature. The bike is booked in for its 4,000km service on Wednesday so might try getting them switched over.

Along my internet journey's I found a website devoted to Korean made motorcycles, it seems to have a lot of information about mods and shit and is forum orientated. Check it out, http://www.korider.com/

Came across pictures of a guy wheeling his GT650R, looks pretty sweet

I reckon the GT250R could easily pop a wheelie, would need an aftermarket exhust, better spark plugs, re-tunning and a bit of practise.

Well I ahve to admit the Gt650 racebike looks fairly impressive will have to keep up with the series to see just how it performs....

I've read in one of the forums on KB before I bought my bike that there was a guy popping wheelies on the GT250R standard so I'm sure you'll be able to pull one with a couple of mods let me know where and when man I'll be there to watch!!!!!!!

I've taken my 250r out on the track a few times here at baskerville. I took the stay upright advanced, and cornering and braking courses. During the course I was consistently above 150 down the straight (to redline at 164 at times, and then a bit past redline a few of those), and while it wasn't for very long it seemed to like it alot. I've of course been out on the back roads and had it around the same speed, but for alot longer periods of time. It still seems to like it quite a bit.

On the wheelie part... there isn't that much go in 1st as I've noticed. I might get them to change the CDI as previously mentioned. I weigh 105kg, and well it doesn't like lifting me up in 1st. Maybe 2nd, but def. not f1st. I tried the tap the front brake, lean back, and drop the clutch... still no go. I only tried it once, but as soon as the front wheel came up, my fat ass pushed it right back down, then the engine got happier again (:

All in all I love this little bike. I've been out of riding for some years now, and decided to go slowly into it again (read: not an R6) and now that I've got some better skills (stay upright) I think I might graduate to a bigger big. It's good though for anything from track days (was a complete blast pushing it beyond it's limits), to just riding for 1200k's cross country... It was a bit uncomfortable though (;

I'm 110kg and had no trouble popping wheelies on my GT250R once I'd worked out the technique. Basically it's a combination of slight clutch (but not much, a very fractional amount just to get it to bounce the revs) then drop it as you load up the front slash and bounce at the same time.

It's a heavy bike relative to the horse power it puts out, but once it's up, it's quite well balanced (compared to anything else I've wheelied anyway).

There are pictures of me doing wheelies and stoppies somewhere on this site, there are plenty of other pictures to be found on Google Images as well. There is a American dude who put video footage up as well, although he'd put on a larger rear sprocket.

A question for you all, wouldn't it be easier to pop a wheelie if you drop the clutch at the rev with the most torque?

[Pancakes]

I haven't noticed any flat spots but it seems there is lots of talk around this in the earlier ones.

I have the naked yellow with the silver frame, recon the black frame looks pretty average on the naked ones.

Wheelies, easy from a standing start in 1st or moving via the clutch in 1st or 2nd. I don't try to get it up tho, feels mean to have it hit the ground from too high! Just like to try to launch it hard.

Got it cos it was new for the same money as an old bike, not as fast as simalar priced used bikes but faster than a busted one!

I', 175cm (roughly) and 70kg, it doesn't mind $1.40 all day long.

I made a straight thru pipe and gained power/extra revs up top and I backed off before the bike did quite far into redline at the expense of lots of torque low down, I don't think the extra revs is enough gain to lose torque for.

You can get a high flow pipe and have it dyno'ed for more power or buy a bigger bike!

it's a real popular bike in Mylasia (sp?) but sold as a Naza Blade, search that.

Personally would have Spectrum (Barrys Point Rd) work on my bike over Mt Eden and have had a number of firsthand experiences that give me reasons for that.
