Starting taking a while

[cleankat96]

Ok so i now have the bike to where i can ride it once its warm, its just getting there thats the problem- I hit the starter button (choke on) and it cranks for about 30-45 seconds before firing up and once it starts it revs to about 5 or 6 grand, i turn the choke down to get it to idle at about 2 or 3 thousand rpms and let it warm up for about 5 mins and then the choke comes off all the way and itll idle around 1500 rpms and it has a smooth throttle throughout the entire rpms and all but im just wondering why it takes so much cranking and why it jumps so high when it starts- Thanks in advance for the help

1996 600 katana- stock jetting

Well , the "stock jetting" may have something to do with it ..... or maybe just something's getting old and needs a little love . Bring the bike by the house sometime & we'll see what we can figger out .....

Ok didnt really get the part about stock jetting, i just meant its all stock

[cleankat96]

could a weak spark be the problem? - Also do you guys think seafoam could help and will seafoam hurt the tank liner?

[suzukiray]

If it is ALL stock, I'll bet the biggest INITIAL modification will be to drill out & remove the mixture screw plugs & adjust the mixture screws CORRECTLY. Ray.

He makes a valid point . Stock jetting is fairly lean on the idle circuit .
And yes , it COULD be a weak spark . I wouldn't count on the Seafoam to work miracles , but it won't hurt nothin , either .

The po drilled the caps out before i got them, i had them at 2.5 turns out and it did the same thing but it was running to rich like that so i backed them down a little- when i say running rich i mean i could smell it and when i pulled the carbs off the intake boots were soaked with fuel- is that part normal?

[md86]

Little fuel in the boots I ASSUME is normal . I've always seen some in there , provided the bike ain't sat for a couple days before I messed around in there ...

Do you think that a factory pro jet kit would make it a little easier to start/ a little smoother- also i was reading how some of the katanas carbs have different size jets in number three is that right?

If you take the time to adjust the mixture screws CORRECTLY, it should start easier, require less choke to start & have better throttle response. Ray.

would that make the slight flat spot at 3000 go away too?

[suzukiray]

It will help it but if it has no work done to the carbs, as in no jet kit, you need to shim the needles about .040 to richen it up a hair. Ray.

Is a factory pro jetkit worth it, as in will it save me some tuning troubles, do you know if it says where to set the af screws and needles at in the instructions?
