stressful high idleing
i dont know what the problem is. but ive had a 94 katana for a couple of months now. ever since i got it. at first it doesnt do it but if i ride for any extended period of time, when i go to stop, pull in on the clutch it idles up to about 3ooo rpms. if i put pressure on the front brakes and let off on the clutch a small bit the rpms will go back to normal unless i pull in the clutch all the way or put it in neutral, i dont know what the deal is.

carb cleaning wouldnt hurt nuffin either.99% of the questions asked here can be answered by a 2 minute search in the service manual. Get a service manual, USE IT.

well i looked at another katana today.. but it wasnt all there,, it was at a salvage yard. and there were some hoes comeing offf of the carbs just couldnt tell where they go to that i do not have,, like i have two tees. one between the 1 and 2 carbs and 1 between the 3 and 4. there are no hoses on them,, im pretty sure that thats gonna be one of my problems,, can anyone help me to know where i need to run them too?Comment

sounds like one of few things:
Vacuum leak
float heights off
fuel valve sticking
o-rings messed up inside carbs or on sync tubes
sync caps missing
Boot/engine orings cracked.
A good cleaning and rebuild with new orings should probably fix it. or you can have a friend help you.Comment

And....i forgot one more. the wrong model of Main Jets (N100 instead of n102) will also cause these symptoms. Don't ask how i know.Comment

thats just it they were pointing up on two other katana motors that i have see today and you could tell that the hoses where conected to somthing bc they where spread out on the ends
and on a schematic i found online they are pointing up as wellComment

Yes that is correct, up if there is hoses on it. You don't want water ending up in your carbs do you? Rotate them down if you don't use the hoses.Originally posted by nealy212 View PostMust read for carb tuners......http://www.factorypro.com/tech/tech_...m_engines.htmlComment

Both of you sound like you're running very lean and that the idle screw is turned waaaay in to get it to idle when it's cold, but then it idles way to high when it's warm.
Do the carbs 101 cleaning. Make sure your airbox is properly sealed. This will give you problems if it is not sealed. Go ahead and run some black silicone around the boots so you know they're good and sealed to the box. Assemble the airbox to the carbs and then put the whole thing on the bike. Make sure the airbox is good and seated on the carbs.
Then sync your carbs. It's easy enough to make a home made sync tool.
After that you should be good to go. If you turn your idle mix screws out an extra 1/4 - 1/2 of a turn it'll eat more fuel but it will also make the bike run much much better when it's cold.Comment
