It has about 250 miles on the rings, and #1 checked out at 135 or so. It was getting late, but today while the tank is off I'm gonna check them all. I still kind of suspect that I need to lower the slides to get the pilot circuit working properly, but I kind of need to get it in the ballpark, and get some miles on her to seat the rings(so I'm just burning gas, not oil too.) Then I will once again delve into the final tuning of it( sync and color tune). But, if I should fail to get these suckers close...feeling some new carbs... also stopped and ponied up 8 bucks a gallon for some 110 octane race fuel, which I will mix 50/50 with the regular crap, hoping it will lay some color on the plugs for me

I was mistaken about the comp numbers, all four cylinders when ice cold were within a couple pounds of 110. Sooo... pulled the needle back up to the middle slot, and low and behold, its runs half decent with fuel in the tank. It is certainly as close as I have had it. She is definitely kind of flat on the top end, and the air screws seem happiest about 2.25 turns out. I think I will toss in the 117.5 mains that I have, see how she runs, and then try bumping the pilot once too, but first I'm gonna take her for a spin. Pulled the number 4 plug for a sneak peek. It looked pretty good, can't seem to upload a pic from my phone, so that will have to wait, gonna take my honey for a spin first.

nice bike, love the progress. i have a ?s about those intakes you put on, the k&n rc-2222's fit those carbs good? the site im on says there not suppose to fit but they look like they do fit on yours fine. I didnt know if you had to modify or make some "adapter" to make them work. Please let me know so i can buy a pair for my bike

i found these and was wondering if they were the same www.amazon.com/RC-2222-Universal-Chrome-...&keywords=Kn+Rc-2222

The rc-2222s fit really well right out of the box. The only issue is that the kick start lever touches the right filter. Here is a thread with a little more information kzrider.com/forum/3-carburetor/526950-ka...s-anyone-tried-these

On a positive note, the bike is running pretty good, put a few miles on it Friday night, and its pretty happy right in the middle, just a bit tough on transition from idle to throttle, and a bit flat on top end power. It seems to run best with pilot screws out around 3 turns, so I'm gonna try stepping the pilot up a click, and after that I will try the main too. I'm hoping the needle stays happy where its at, but wouldn't be at all surprised if it needs attention after changing the main. Oh yeah, it seems that the ole girl has expensive taste too, as 8$ a gallon race fuel really smooths things out!

haha oh ya mix some race gin right up! shell run real nice with a race fuel/93 octane mix haha im buying those filters on amazon cause you said they fit the mikunis so im gonna buy a set for my next build!

www.amazon.com/RC-2222-Universal-Chrome-...&keywords=Kn+Rc-2222 found these on amazon tomolu5 are these same ones you got on your mikunis?

yep! So, a little update, I had her out and about over the weekend, and to start things off, Saturday I had it sitting at the top of my driveway, 3 people(hippies actually!) Stopped to ask if it was for sale! I took it out to run errands, and every where I stopped people were asking about it! I walked out of the hardware store and some lady was talking pictures of it! Struck up quite a few. conversations too. My wife really liked riding on it too, she liked how comfy it is, that's pretty much a green light for me to throw some more money at it

thanks for feed back! i just bought them waiting your confirmation! Glad you got good looks and comments on the bike! that always helps motivate a project!

So I got a little wrench and saddle time in tonight, Staying true to my "change 1 thing at a time" concept(new to me) I stepped my pilot jets up from the stock 17.5, to a 20. I put it all back together< set the air screws at 1&3/8 turns out, and went for a ride. aside from the fact that it would not idle reliably, the entire bottom half of the rpm/throttle range was happy. Smooth and powerful up to four or five thousand rpm, still somewhat smooth after that, just low on power. She smells a bit rich at idle, and will give a "poof" of smoke when reved, but she seems smoothest right now, and I am pretty happy with that. now I just need to mess with the main jets, I think if I fatten that up to a 117.5, maybe a 120, I should be good, although my needle may need to move once in relation to a new jet. I am kind of tryin to tune from the bottom of the rpm band up. I dont know if this is the right way to go or not, but I am closer than I have ever been. I have some photos to upload, maybe tomorrow, got some pics of the car too, even took a video, but it didnt come out.

bring on the pics !!!!!!!!!!!!!!!!!!
