So the rejet is complete. #40 pilots, single #4 washer under the needle, 125 mains, 3 turns out on the air mixture screws, and it now runs like a champ. Warmed up in nearly no time, but I have an interesting dilemma now. When I turn the wheel to the right, the bike throttles up to 6000 rpms, but when the wheel is facing forward or to the left it idles at 1200 rpms. Anyone else have this problem after a rejet? Weird. :dunno_white:
Throttle cable is too tight. Set slack with the wheel to the right.
Could be throttle/choke cable wrapped the wrong way, or unbalanced carb float. When you turn, are you tilting?
Right and revs high is usually choke cable, but hey check both. 6K is rather high could be both.
Cool.
Srinath.
Thanks...I'll check the routing, and give you an update. The bike revs when turned right whether upright, on the centerstand, or on the kickstand. And the revs increase when I try to move the throttle cable. I probably didn't get the throttle cable properly adjusted after removing it from the carbs.
We'll see. At least it's raining here a lot, so I'm not losing ride time.
Update: Cable routing issues have been solved, and I got her out for a good long ride. :thumb:
Let's see, all I can think of to say is the same thing that everyone else says. Much shorter warm up time, off the line excelleration, and powerband throttle response. No babying it from stops to keep the throttle from stumbling...just goes. I love it! I kept finding myself waiting for hesitation that no longer exists. IMHO, this should be the first mod that anyone should do, with progressive springs being a close second.
Oh, and the Avons are great too. I found my self in corners that normally had me drifting too close to the center lines, instead were rock solid. As a matter of fact, I had to relax my turn-ins because I would end up cutting in to the apex sooner than I wanted. BTW, I replaced a well worn battlax rear, and an stock excedra front. LOVE IT!!!
P.S. I turned over 15,000 miles (5000 of those are mine) on my odo today on my test ride, and the bike runs better than ever. Now I just hope to have the time and funds to make it to Deal's Gap June 9th - 11th. :cheers:
Are you running the stock airbox and exhaust? I've been looking for a good suggestion on main jet sizing for the stock setup.

Getting GS500 carbs properly jetted and synced is one of the ten or twelve most rewarding accomplishments known to western man; I'm glad to know you got it dialed-in. The GS engine can be almost as responsive as any "double-twin" when you take the time to dial-in the carbs; it isn't rocket science, but it isn't something your local librarian can do. It takes some time, patience, and effort, but the results are well worth the aggravation.
Now, ride the rings out of it...
oramac: Great to hear. I should be following your footsteps soon, with the same carb setup. Every stop seems to be a challenge and taking off too.

Oh, I forgot to mention that. I'm running all stock. The only mod to intake or exhaust is that I completely removed the rear baffle in the stock exhaust. I basically took the 'drilling' technique to the next level and filed out the material between the holes I drilled.
And once again, I went to #40 pilots from the 37.5 stockers, and 125 mains from the 122.5 stocks.
While I'm rambling on about my carbs, it might be interesting to you all that when I pulled the brass plugs to set the mixture screws to three turns out, the left side screw was open maybe an 1/16 of a turn. It was nearly completely closed. Weird :dunno_white: It's all good now though. 8)
Mine is all stock except for a UNI foam filter. The carbs already had the brass plug drilled. Maybe its already been jetted. Sometimes it seems to be rich. When I pull the choke all the way in the morning, i still have to twist the throttle to get the rpms higher than 1500rpms. Today being warmer, I didn't really have to.
Well either way, I need to get the carbs out, clean it and see what's going on.
I know when running as speeds above 35mph and putting it into neutral the rpms can go straight to 0 and the engine stall. I tried doing that with the choke on and it does it still. So maybe the it has been jetted with the PILOT at stock 37.5 and the main maybe at a richer setting. Also I still haven't checked the float level, that could be causing that symptom as well.
