No power!!!

[Spyder1984]

Hey guys, i got a hyosung gt250r and have just changed the oil, oil filter, battery and spark plugs. but now when i start it up it either stalls when i put it in first gear or if i do get it in gear it has no power when i accelerate. any help would be appreciated.

Plugs on the correct order?

check all the lines are on your fuel tank

including the small vacuum line coming from your carb

[Spyder1984]

yeah, highly impossible to switch the leads around especially with where the plug are situated. one under the fuel tank and the other at the front.

Have u put the side stand up, before putting in gear

[Spuddy]

Any chance one of the plugs haven't been re-inserted properly?

[Spyder1984]

theres one line coming from my fuel tank that doesnt connect to anything and one from the engine that also doesnt, but cant find any place to connect either of them up. weird noise coming from carby direction too. stand is up. lol, i woulda bout a different 250 if i wasnt so tall

[Spyder1984]

plugs are installed correctly, tightened firmly and leads securely on

does the engine sound any different?

[Spyder1984]

yeah a little, the noise from around the carby area does sound kinda airy. if that makes any sense. its just so strange cause i didnt do anything except what i mentioned above and that shouldnt have created any problems.

put up the side stand?

[Spyder1984]

lol, the side stand safety was actually disconnected by the guy i bought the bike off.

[lee]

intelligent..

reconnect it

[MaximPrime]

It quite a common problem for the side stand switch to short out.

As to why most people disconnect them.

one of the little tubes coming from your carby is a vacuum line which should suck when you turn the engine over.

You need to connect this to your fuel petcock as the vacuum open the fuel line and allows the fuel to flow fast.

If you don't have this line connected you might be able to idle it but not much more than that.

Look on the bottom of your tank on the fuel tap more closely there should be a small tube where the line can attach.
