For Ian

i just looked... NONE of the carbs have that air jet! could there be a reason for this?

the guy i got the parts bike from (found out later it had smoothbores on it) said he bought it from a dealer...perhaps they did something with them.. either way Z1 will be getting some money from me soon

Did it run like that?

never had them on the bike! the guy hit a fire hydrant going home from the dealer (or so he said) and bent the timing advancer so the bike wouldnt run...bike sat for 2 years and i picked up a complete 79 sr for $150 bucks that came with smoothbores and aftermarket coils, and tapered steering head bearings, so i coulnt really tell you but the guy said it came from a dealership, the key still had the dealers tag when i got it from him. but what else is odd is that its a 650! no work done to it...and they put on smoothies? i dont know much about jetting but i think they are 115 mains if i remember correctly and from what i have read 105 mains should work for the 650...

The fact that you got a bike with a set of smoothbores for $150 tells me that they didn't know what they had. It probably never ran like that. I don't know what would happen if you tried running it with no air jets but I'm telling you that there is a major restriction missing in that circuit if the jet isn't there. It can't possibly be good.

ha definetly will replace those prior to doing ANYTHING with the carbs,

what i have in them are 115 mains
0-2 needle jets
17.5 pilots
needle clip is on the second to last clip...

Following info from Z1E:

29mm smoothbores KZ650
Main Jet 105
Air Jet 0.9
Needle Jet O-4
Jet Needle 5DL31-3
Throttle valve (slide) 1.5mm cutaway
Pilot Jet 15
Air Screw setting 1 1/2 turns out

Good Fortune!

Got the carb back in the mail today, havent taken it apart to look at the labor yet but its back!

Thanks josh
