Ive been doin searches for a couple days and tried some things out but nothing has fixed my problem.
First off, its a 1996 Kat600 with 2600 miles all stock to my knowledge.
Problems: it's got rough idle, when starting up at half choke, if you open the throttle a little too quick it just kills the bike. you gotta open it slow, and even then the rpms are rough and slow.
If you do try to open it slow then rev high, the rpms rev right to about 2900-3000 STOP for a second then quickly and smoothly rise to 6-7 whatever rpm.
Now ^ was at startup, after riding for awhile, coming to stops, the rpms will drop to about 3k where it hangs then slowly drops to maybe 1.5k. but after maybe 6 seconds at 1.5k it'll then drop to about 900. Sometimes itll stall here but most of the time it fluctuates from 900-1100 but very consistently. sort of like clockwork, reving between 900 and 1100..kinds sounds like the bike is breathing.
So i read through carbs101, took out the carbs, tried to clean them as best as i could following carbs 101. I got the the pilot jets cleaned and the main jets. I checked to make sure the throttle cables werent getting pinched or too tight or anything. I tried to test for vacuum leaks spraying wd40. I checked the air filter, seems clean.
Im still having trouble though and im not sure what i need to do next.
**I accidently did skip the step about taking out the diaphram slides w/the emulsion tubes..i know i should go back and take care of it, but dont know if thats my problem.
**The baffles on this bike have been punched through, not sure if that's a big deal or not but ive heard stuff about exhausts needing the right backpressure and stuff
**I havnt pulled the plugs, i dont really want to spend $40 on those NGK CR9EK plugs, are there cheaper alternatives?
any help would great- Thanks
oh yeah, and A/F screws have been turned 1.75 out
