Comet GT250 OwnerShip Thread.

the bleeding of the brakes should not take longer than 2 hours tops if you do it by the old method. if you have the right tools, it takes less than 15 minutes.

just double check if there is air between the pistons thats causing the issue . sometimes the seals go in a caliper and that can be a problem. the pistons essentially dont want to go back and get stuck jamming the brakes.

true.. but i don know why they took 2 days and still couldnt fix it... i am doing it myself now...

sad to hear that :\
so just stick with them for the parts

well about the parts, i believe the pricing is not going to be that cheap cos the service manager told me that they are getting the parts from Korea and will be expensive...

got my bike finally! pics here: https://www.facebook.com/media/set/?...8944130&type=3

hey buddy..bike looks spanking...
would you be kind enough to tell me how much you spent for the paintjob and if possible, the place where you got it done..
I would be most grateful

thanks in advance Push

thank you bro

got it done by the one named Faiyaz (A to Z Garage), near J.J. Hosp.

approx. 5K for entire paint-job

also, added this: http://www.planetdsg.com/keiti-reape...400-p-802.html
alignment got a bit out in the lower portion, but damn, it looks good, plus it does what it was installed for

[pushprajpradhan]

added pics with tank pad, check 'em out

hi bro,
thanks for the info braddah..do u ever come to bandra side? would love to check out the finish..

don't come to bandra side, once in blue moon maybe, but surely plan to come there for rides with friends, will surely let u know, pm me your number

The good thing is that that atleast we are getting the parts from them.

A Comet was the bike marketed by Kinetic way ahead of its time.

Such a bike by now, may have ,
1.Braking Issues : The disc pads of this bike up front and back do not match with any bikes present in the market now.
2.Worn Chain and Sprockets : original does the best job.
3.Timing chain, valve set : I have to repeat the solution of point 2.
4.Dual carbs : Time to go Flatside by now, but still they need balanced tuning.

The GT250 is now FIed all over the world, except in Korea- the home country, where there are carbed variants for Asian markets......hence the engine internals along the carbs and airfilters and oil filters is needed to maintain this bike.

One of my firends got a Hyosung Comet GT250 recently, Got to go to Hyosung Garware to get the parts then .......

[vijith.unnithan]

Noticed something with the bike recently... when i try to ride at anything beyond 80.. the bike keeps pulling back.. is this something to do with teh carb...

i had teh bike serviced recently and have ridden 1500km till now... any pointers on what checks need to be done...

Many things can cause such issue :
1.Check the spark plugs - needs change or not.
2.Check for electrical leaks in the ignition cable which powers the spark plug.
3.Check the air-filter for cleaning.
4.Has the fuel tank got rust ? - Rust bits may mix with fuel and lead to carb malfunction.
5.Does the fuel tank has proper drainage channel for water ? in case water from showers(natural or cleaning) may keep getting mixed with the fuel and preventing high combustion.
6.Do check the carb for main jet clogging or status of mainjet and if that requires cleaning or tightening.Also drain the carb of accumulated impurities.

Go for the above checklist and update, I am sure it is one of them

Thanks, Mach...

Mostly Point 1, 5 and 6 are something i feel could be the reason.... The electrical wiring was completly redone and if there was any issues, then even starting the bike would be a problem right?

as fo rthe rsut.. the bike was repainted recently so not sure if it could be one of the issues....

what i did notice was that at times i do smell petrol form the tank... not sure if there is some kind of leak.. will get these things chcked...

No, not always.

Actually mordern bikes run Cdi , when the voltage load increases as we turn on throttle.....there comes the loop holes of a weak circuitry- a lot electrical pulses are dissipated and the spark plug do not get enough power to fire up the AFM(Air-Fuel Mixture) volume then being brought in the combustion chamber by the engine.As a result, bike suffers the pulling power,as the engine gets bogged by the unburnt AFM volume.

If not the wiring, then try using high quality fuses and change the ignition cable(this is only the cable which is plugged on the spark plug).

Also go for a check of all the points in your accordance.

Thanks a lot, Mach.. Also, any suggestions for what Spark Plug needs to be used in the Comet's

Comet GT250 needs NGK's CR8E spark plugs.
The normal is CR8E and the irridium version is CR8EIX of NGK.
Bajaj Pulsar 220 uses this spark plug.


Also, I forgot one point to mention,
Most twin cylinder carbed bikes like RD350 or Jawa 350 twin suffered from problem of mistuned carbs.
You know, the state of tune should be balanced and be same for the both the carbs that fuel the two engines.

The 250cc of Comet is basically two 125cc chambers in V configuration.
So if only one engine is powering the bike at major throttle play it will evidently lack power past 80kmph for a bike that heavy.

Hence please do check the overall state of tune, the carbs are in.They should be balanced and tuned as per factory specs.

[pushprajpradhan]

even my comet won't go above 125, as in, it goes smooth till 125, but it just dies after that, going for a service this monday, lets see if it gets resolved
