Those look like the MAC 4 into 1 exhaust. It's what I have on my
CB650.

My guess about you hi-revving is that your carbs are WAY out of sync.
I had that problem as well at first. My carbs got synced, so now she idle's nicely,
but I still have other issues as well. The carbs, IMHO, are the biggest headache so far
for me. I am looking forward to see your progress.. so keep posting pics.

Try turning your fast-idle knob 'til it lightly seats, then coming out a couple turns.  See how it runs/idles from there.  I idle-fiddle, even though I shouldn't really need to.  I just can't leave well enough alone. :D

Well, unfortunately about the exhaust I am missing the "into 1" part. The bike just came with the headers, I guess I will have to fab up something.

PARTS ORDERED!

I just ordered new pod filters, clutch cable, starter solenoid (hopefully the right one).

I also managed to fit a kawasaki kz750 or 900(?, not too sure) front master cylinder up and it bolts right in place using the cb's brake line and front caliper.  ;D Of course, it says "kawasaki" right on top, but it beats having to rebuild the original one, plus it was in all of the parts that I just bought for $50. ;)

Well, I am excited to get this far with the bike, and I will attempt to keep you guys current with my build, however I will be in Mexico on my Honeymoon next week so I won't be posting. I am getting married this Friday  :o So pray for me, and if you're not the praying type, have a drink for me, and if you're not the drinking type, then do whatever it is that you do.
