I just installed a Ivan jet kit and 5 degree advancer. I synced the carbs but it idles way to low and stalls. I've adjusted the throttle lock screw both directions but to no avail.
You didn't get everything sealed up right... there's a leak somewhere if you've got your fuel-air (pilot) screws to 4 turns out. My advice: disassemble again and start over.
My best guess (most likely to be missed): the drain hose for the airbox.
Ok...part of my problem is that I only did 3 turns out on the air/fuel screw. Fixed that and put the carbs back the on...now my idle is way to high...3.5 rpms. Again, I tried adjust idle screw to not avail.
DUHHH!!! Ok...so I noticed the throttle return was not adjust correctly. Once adjust the idle came down and I was able to re-sync the carbs. All is well now. I just took her for a spin...I love the reduced vibration and increased throttle response.
BTW...my home made manometer (carb sync tool) worked great.
It was fairly strait forward and not that difficult. I really only had two issues when installing it. One, I used the instructions provided by CyberPoet at www.motorcycleanchor.com (CP....great instructions I would not have been able to do it without them) in which it says to turn the air/fuel screw out 3 complete rotations...However, Ivan says 4 complete rotations (my fault as I should have read the instructions more carefully). Also, was some vagueness when setting the float….but I think this was more my fault as I do not have a lot of mechanical experience.
My second problem was again my fault. Not adjusting the throttle return cable correctly.
As for the advancer…that was a 5 minute job and I had no issues with it. I would suggest buying some gasket maker as the paper gasket does not fair so well (at least mine did not). Simply put a small bead of gasket gue around the cover.
I would highly suggest the carb sync when done. Do you have a carb sync tool? I made my own and will post pics if you want to see it. It worked great and the sync really made a difference.
yes i do have a carb sync tool.i wish i could install the advancer but i live in south texas and my engine would run to hot with it.which of the two made the biggiest improvement?

I live in cetral texas...not sure if i will have problems with the heat of the engine...not something i thought about. I can see the jet kit making it hotter but the advancer only moves the power band. Will the advancer generate more heat?
Anyway, I installed both at the same time so I'm not sure which mod had the most effect.

The jetkit.

The jetkit will make the engine run cooler, oddly enough -- the leaner the burn, the hotter the combustion. The jetkit richens the mixture everywhere off-idle.
The advancer increases the heat because it causes the spark event to occur earlier in the mechanical cycle, effectively making the engine hold the detonation product longer before the exhaust valve opens.

So...because I live in central texas...should i be concerned about the extra heat that is generated?

Well, I don't know your riding surrounds very well. If you are in a location where you do 80 mph on the highway mile-after-mile, or typical county-road cruising, no issues. On the other hand, if you hit a traffic jam after all that cruising, it can increase the speed that the engine gets too hot by 20 - 30%. Standing still after a high-speed run is your enemy -- the oil cooler needs air flowing over it at 18 mph or faster in general.
If you're in an area where you're constantly in 2nd & 3rd, rev'ing it out as you scrape around turns, that's where the heat difference is maximized and you can run a risk of overheating without noticing fairly easily (causing the oil's viscosity to quickly fail -- won't see many noticable warning signs -- part of why I run the oil temp gauge I sell). When we were doing the KR rally pictures with KillBoy last year, I noticed after a dozen or so high-speed 3rd gear passes past the camera, my oil was up around 375 (F) and climbing a bit each run, and decided to go park off while the rest of the crew continued to run it -- better safe than sorry.

Well...I put about 75-80 miles on my bike everyday. I do make a long run on the freeway about 25 miles or so then hit in town traffic (a few miles) going to the university. Dring class the bike is off for about 1 1/2 hours. After class I make another freeway run from the university up to north austin...about 40 miles the last 10 of which are stop and go (stop at several lights and then get right back up to 60-70 mph). From there the bike sits most of the day while I'm at work. I then take the 18 mile drive home in stop and go traffic most of the way (with spurts of 50-70 mph).
This does not include any weekend driving (however I drive like an old man most of the time...but i do like to get on the throttle every now and then). Do you think i should put the original ignition advancer back on? How much of an increase in performace does the 5 degree advancer produce. If it's minimal, then I defently will want to revert back to the original. If it's significant, then I do not want to lose out on performance and will go with the oil temp gauge. How much is and how hard is it to install?
I'm to ignorant in these matters to even ask the right questions...so is there anything else I should be aware of?
