Well, the fuel tank was pretty clean, it filled it up with mineral spirits and nuts and washers and shook it about, drained it. took apart the petcock, cleaned it, replaced oring.
Full on rebuild on the carbs,
they had 102 main jets..the kit i bought came with new 102.5 and 105 so i put the 102.5s in since i figured it has a kerker 4-1 and no air filters at the moment. it had .015 pilots and the kits came with those i put them in, new needle and seat, choke o rings, air screws adjusted 1.5 turns out.
Float level isn't consistent between all of them but i think i'm going to make them higher..
I have ok spark..its strong enough to hear but i think the 30 year old coils and wires look like they could use a break..compression numbers worry me alittle..now remember the bike has been sitting for 10 years or so..20,000 miles on it, modified. so valve clearance is probably out of whack i'm guessing. and the motor was cold and i have ran it maybe a total of 5 minutes so far
Cylinder 1 2 3 4
135 125 120 110
... please tell me its not a loosing battle with numbers like that..
I plan on doing some sort of homemade mercury manometer balance and i have an IR thermometer as soon as i get it to idle consistenly..you puull the choke up and it revs up and sounds decent..but at idle it sounds like its loosing a cylinder and backfires through the the #2 carb
If you try to open the throttle it kinda..seems like it falls on its face unless you do it slow, and even then it seems sluggish and backfires, lot of black/brownish smoke coming out of the exhaust.. since then i've taken the carbs off and done my best to set the slide level as even as possible between the 4..there were a few that were off by enough to notice. I also cleaned and spray lubed the ign. advance mechanism.
so..thoughts / ideas on the compressions numbers? thanks for the warm welcome, guys

hopefully with some lube and maybe a lil run time the rings will free up and the compression numbers will come into line.
it takes 75 pounds of compression to create combustion.
100lbs is worn out.
