JUST GOT WALBRO CARB,JETPRO PIPE,ROCKET KEY & CLUTCH SPRINGS NOW BIKE IS SLOW AS HELL

I have just purchased upgrade kit for my x1 ninja, everything went to plan ,
fitted rocket key,heavy duty clutch spring, walbro carb with vstack & filter * jetpro pipe...
i have set my carb up using the guide on this forum with low & high carb settings, but its just got no pull away, bike idles ok but dosent have any power now from pull away & takes ages to wind up..
I checked plug its nice tan colour so it aint carb i dont think, as i does pull away ok dosent die under any throttle position and idles great..

i dont understand it! its driving me crazy

any points i may have overlooked?
i installed rocket key with cut out facing exhaust this right?

I Bet The Rocketket Is In Wrong

i got my key and i scared to put it in lol

I would take the rocket key off all together. They are not suited for these engines once other mods are installed.

what makes you say that????

the rocket key works fine if you put it in the right way, and also they can somtimes fall out during installation. you may want to go back and check it out, and also i dont know why people try to say it is nogood, it may not be the biggest gain your going to see but bottom line is it WILL advance your engines timing PERIOD .

something sounds really wrong here. i would just try putting all the stock parts back on and see if it runs crappy still. if not, then try reinstalling the new parts again, and if it's crappy, then one of your parts might be faulty.

Thanks guys worked a treat! I had the key in wrong way round so retarded the timing instead of advancing anyway sounds and goes well now and what a difference from stock! just need to fine tune that walbro now

good to hear

Ok then--WHich way did you put the key in?

which carb did you get?

how much more power will iget if i put that juice box on my x7?

i dont know how much gains you will get but it does make a diffrents i am also selling mines if your interested PM if you are.

A timing advance key should be installed with the offset in the direction of flywheel rotation.

how are you telling people to take stuff off there bikes and whats not suited for them and you dont even know how to install one your self

hey guys/ or 7star,

i got the walbro carb today. installed it in minutes with 4 hands!

anyway,

there are supposed to be a high and low adjustment. am i to assume, the flush mount blade type screw up by the throttle linkage (on top of carb) is the low speed adjustment? if so, what are you guys using to turn that head? a speciality screwdriver?

just a note on the carb.

i now have the juice box, billet filter/vstack/choke and carb. today my bike was hauling *** UP THE HILL! i only adjusted the side screw (the high speed screw) and not the screw up top (which i hope is the low speed) and this bike took off! i am very pleased with this carb. my take off speed can be better which is why i am asking about the flush mounted screw.

can somebody show me a pic of the high and low screw or w/e I got my walbro on it runs ok but it can be better I got 43 pocketbikes keepin up with me for a little then my topspeed kills them but still very sad

what kinda walbro carb did you get ? i have the 668 and the 603 and both have the high and low right next to eachother there should be a little l and a little h below them

thank for the reply.

hmm, mine does not have that. i got it from ada racing.

it is the 15 mm carb on their site under the 49 cc bikes.

i see the side screw but do not see another screw except the one thats flushed on top..

let me know 7star.... thanks,,,,,

The carb you have is a Walbro WYK series carb.
The screw on the side is the high screw. The flush top screw is the low screw.
