ZL 600 Jetting and Mods(I finally got it right!)
Hey, guys! Just wanted to drop everobody a line and relate how y'all(yeah, I'm in Georgia!) have helped me IMMENSLEY in getting my "96 600 straighted out---
Took off the #@%$#% airbox and accompaning junk, and went to UNI socks and a Dynojet stage 3 kit. I'm running Cobra F1R's, and had a plug(!) that stripped out, so re-threaded/Helicoiled all four cylinders for 14mm plugs, now running NGK B8ES's. When I first started the beast with the origional setting as directed by Dynojet, the bike ran good---for about a mile, then just quit running! Classic rich syndromes-wouldn't accelerate, blowing black smoke,wouldn't idle, and stalled/wouldn't start. After pushing the beast home...Next day, changed some stuff! I used a combination of info from about EVERY post that had to do with 600's or carbs, and here's what I came up with---
Needle circlip in groove #3-
130 main jet-
2 turns out on the idle mix screw-
Got it to run WITHOUT the filters on it, but put them on...nothing past 3k revs. Sooo... went another 1/2 turn in on the pilot air screw, and checked the installation of the filters, and...OMG, it idles! It runs! And...it RUNS like a molested primate! Now, I see what you guys have been talking about!
Revs to redline in each gear, just a little fussy down at the bottom, but other than that...WOW!!! What a difference! I put a filter on the end of the head breather, along with about 6 inches of hose, so I would maintain vacuam at the valve, to keep the vacuum on the petcock for adaquete fuel. Used a Mr. Gasket oil breather for this, as it was kinda large, and could create kind of a venturi effect. I mounted it behind the right side cover, so it's in the airstream. I'm setting this up for the AMA/Prostar BikeWeek Nationals, at Valdosta this weekend, so I also put about 8 inches of hose on the crankcase vent, and ran it into the empty air filter cavity, with a filter on the end, sitting in a cut-off plastic bottle/catchcan, in case of "catistrophic failure"!(Per the Rulebook!)(OK, I'll admit it...The UNI sock filter were not fitting at all, so I cut them down and bought some rubber 2"-1 1/2" neck-down adapters at Lowe's, and put a course piece of foam UNDER the sock...and found it was CHOCKING off the airflow, so I took out the coarse foam, and it all cleared up! The adapters are 50mm at the 1 1/2" side, so they fit REAL well over the carb inlet! Hose-clamped on, and I got a filter!) This has been an odyssey that's coverd the last three months, since the end of the drag race season(for me) in November, when the carbs grunged up, and I decided to do away with the airbox. I REALLY could NOT have done this without out the help of articles from---ANY of you guys that posted ANY info on ZL600's on this site--believe me, I"ve been through all the posts, and there is a wealth of info---I must have used a piece of everything that's here---including some info on the 900's and 1000's that was at least a guide as to what I could do and where I could go with this thing, especially in the wee dark hours, when I was THIS CLOSE to putting a bullet between the beast's eyes, and leaving it to rot! A great big THANKS!!! to all of ya, now I can concentrate on racing, and stop dirtying up my wife's kitchen sink with gasoline and carb cleaner!(LOL!) Wish me luck, guys, I hope to do us proud, and mabye I'll see ya at the races! Take Care, God Bless, and......
