Mark im thinking your going to have to live with the reversion with that lobe center. maybe 2 deg advance on the intake would make a world of diff. It would take advantage of the high lift, more volume and higher air speed.
My clacking is very good now. Very little at all.

Back when I first started my engine, I could barely keep it running unless the choke was on (brand new carbs, new engine rebuild). As I had posted previously, I changed the pilot jets from 17.5 up to 22.5 and it was much better. I then went down to 20 pilots and synched the carbs - another big improvement. Fouled a plug and decided to lean out some more.
Went to swap the 20 pilots for 17.5's today, and just to be sure I checked the 17.5's to make sure they were clear. 2 of them were totally plugged up!!:ohmy: I just cleaned them and will try again - what a pita!!! It sure makes it difficult to tune carbs when you have several variables changing at once. I'm trying to price having them dialed in on a dyno. Maybe it would be worth it just once??

I used my colortune today with the 17.5 pilots and it seems to be idling nicely. I'll have to give it a quick ride when I have some time and see how it runs.

I finally had a chance to ride the bike with the 17.5 pilots, the needles leaned out one clip, and fresh fuel. It seemed to run OK until I was holding steady at around 40 mph. It started to surge and lunge and then died completely.
I was thinking plugged fuel vent so I popped the cap open (didn't hear a suction sound when opening). I then closed the cap and restarted the bike - it ran well until doing the same thing again about a minute later. I came home and took the tank off to check the petcocks and vent. The fuel flows out of both petcocks (dual pingels) on the Reserve and ON positions. I also heard air venting from the cap when I was moving the tank. Vent seems OK?
The weird thing is that I noticed the fuel flows much better with the cap open. Is this normal?
Can the running problem be caused by float level? Can the vent be too small for 34's? I never had this problem with my 33 sb's. These new 34's seem to be a total curse!! I'm at a loss and I'm about ready to trade it for a Harley!! :blink: :laugh:

Try running it with the cap open .
The other posibility might be the size of the float seat?
I am just jetting my rs34's for the 1200cc motor now.
I am starting with 17.5, 3rd clip, 127.5 mains.feels good so far. 145 miles on it.

I'd also like to get a fuel level tool. I set the floats mechanically but I'd like to check the actual fuel level. Any idea what size threads are used on the float bowl plugs? It seems I could fit a plug with a hose fitting and check the level if the plug is a standard size.
I guess I'll try to take apart the fuel cap and see what I find with the vent. I should have ridden it for a while with the cap open to test it, but I pulled off the tank before I thought of it...:blush:
