how much is a jet kit? and where would i get one?

and also i have a problem that another youtuber is having. i have 2 pistions running good( firing and getting hot) number 3 and 4 but number 1 and 2 are not getting hot like not getting gas to them. so my question is to you how do i get the carbs off? i trued but the air box is in the way and i think i saw a clamp screw on the carb do i unscrew that and they will come off or what do i do to get them off?

@redshirt489 I can't tell you how to do it from here. Get yourself a manual and use it as a guide. I'd check ignition and the general state of tune before you go tearing into the carbs. Plugs, wires timing, ect. Keep in mind that the fewer mods you make, the more reliable the bike will be.

does the air firlter you have on it now make a big difference/ more power or anything?

[yellowbusguy]

@redshirt489 Hey red : These air filters look cool and makes the bike sound better at full throttle. The power gains you will get are small, if any ,and you will have to install a jet kit so the bike will run right.

where did you get the air filter/ and remove the air box?

[yellowbusguy]

@redshirt489 These air filters were bought off the shelf at a local bike shop. K & N carries a full range of these in different sizes.

Hi! I am building same model z650 bike at the moment. I did put same pods in my bike in this week, so I need to know size of jets you put in your carbs to make it works? Did you made any other mods or adjustments in your carbs because of pods? Thank you very much of you good videos about the bike!

@colmmorley So you put the 250 into a buggy? Cool. My guess would be too lean on a cold start. If you have removed to air box and done something to open up the exhaust, you really need to re-jet to get your machine to run it's best. Its'going to be making less power than the stock Ninja setup had, so a re-jet will get the power back and then some.

Haah I have the exact same filters on my Ninja 250 engine that i fitted to a buggy, but its impossible to start it when cold but starts really easy when warm what do i do?? is it to rich of to lean?? having some problems this these carbs and tuning
