Here’s a rundown from SOHC forum member flybox1 on how to find a hangup in your accelerator pump. This guy has a lot of great advice.
"you’ll need to have these carbs off the bike but all together, the accel pump fuel lines OFF, carb bowls off and accel pump disassembled.
#1. start with the nozzle system. take your trusty can of carb cleaner, and spray into the male fuel line barbs of all the carbs to see if the nozzles spray. DO NOT PASS GO until all 4 nozzles spray and the male barbs on carbs 2&3 spray straight through.
#2 spray UP into carb #2 at the point where the #2 carb bowl check valve meets the carb body. its a really small hole. if you get spray, out of the nozzle, and its male fuel line barbs, move on….
#3 Carb bowl #2 check valve. spray up into the bottom of the carb bowl, where the accel pump mates to it, and see that you get spray out the check valve. if you do, move on
#4 put the #2 bowl back on the carb rack with the 3 screws. dont forget the o-ring at the check valve. tighten the screws as you normally would. spray carb cleaner up into the bottom of the #2 bowl as you did in step
#3. do you get spray out of the nozzle and male fuel line barbs. is your o-ring to fat and causing the check valve to be blocked?
#5 spray carb cleaner into the accel pump bowl check valve. does it spray adequately. it should come out fast and in a spray. if it does, reassemble the accel pump onto the bowl. and insert all of the cleaned and clear connecting fuel lines, including the brass spacers between the carbs.
connect an auxiliary fuel supply to your carbs so that all the bowls fill.
i’ll even use a really short stiff section of fuel line and attach a small kitchen funnel, and fill the bowls. the short fuel line should be able to support the funnel without your help. fuel will start build up in the funnel when they are all full. stop adding gas at this point. dump some out if you need to. you only need enough to keep the #2 bowl filled.
#6 actuate your accel pump rod to prime the system. either turn the throttle bell manually(i hate fighting the return spring) or get a small screwdriver onto the tip of the pump rod. press it up and down. you should have spray after the system primes. if you dont, you need to recheck your diaphragm and spring setup….its the last link in the system, and you verified all other parts were working.”
All four nozzles from the accelerator pump are shooting gas now. Aiming to get the carbs back on & try a start tonight.

Hey guys, I’ve been writing some songs & would love it if you’d pass the word along. Have had a ton of fun playing for people & will pursue it more as the year goes on. Here’s my page on Facebook.
"Fighting the state begins with fighting your own addictive needs for entertainment and emotional validation. Cut off the television and the internet. Avoid propaganda. Read old books. Stop participating in race and homosexual debates. Think for yourself, without Twitter, Facebook, smartphones, or Netflix, and come to realize the important truths of the world through your own observation, meditation, action, and study. Once you’ve helped yourself think clearly and live deliberately, all that’s left is helping one other man do the same." - Roosh V, "We Are Nothing More than Distracted Sheep in the Real Game of Power"

What my carbs used to look like…
Short update: Yesterday I took the carbs back apart & cleaned all the passageways for the accelerator pump. On carb #1, the rod that shoots gas horizontally into the carb wasn’t working. I got it fixed, & all the other rods & passageways from the accel. pump were shooting/flowing nicely. Assume the main issue is the ball in the accel. pump plate being corroded, but again, I’m not able to get down to clean it. I let it soak in carb cleaner for about an hour yesterday but didn’t test it yet. I was waiting on a new plate from a guy on SOHC forum, but he said he’s got a tight schedule at the moment & I haven’t heard from him. Will get back to it tomorrow when the new float & drain screw get here.
Carbs are back off the bike. Man, things are a lot easier the second time around. Had to remove them because the accelerator pump wasn’t shooting gas up into each carb (definitely a cause for rough starts). I’ve checked most of what I can with the pump. A simple shot of carb cleaner through the accelerator pump hole up into the second carb will shoot through the rod into the carb, but won’t follow through the rubber tubing up into the rods of the other three carbs. I’m not sure if it’s just taking the path of least resistance or if that tubing across other carbs is blocked up. So yes, I’ll be taking the carbs apart again, but now it’s a process that I know how to do within an evening’s time. A guy on the SOHC forum has agreed to ship me a new accelerator pump valve to replace mine. He’s only charging me for shipping; that’s how rad these guys are. Hopefully that will resolve any issues I may be having with the accel. pump valve. The ball inside this may be corroded, but I have no way to remove the brass piece that covers it to get down & clean the ball. Here’s a photo for reference:
One of two tiny metal balls lies beneath that brass piece you see above. It’s very important that it doesn’t have corrosion on it in order for the accelerator pump to work properly on Keihin 41/42 carbs. The second balll sits inside a shaft on the second carb’s float bowl:
I had no issues removing & cleaning this one because on my carbs it was covered by a small plastic piece rather than brass. Note the o-ring here, also crucial for the proper operation of the accelerator pump.
I’ve adjusted float levels down from 14.5mm to 12.5mm. I accidentally broke off a tang on one of the new floats when I adjusted them last time, so I just used an old float along with three new others when I first put them back together. Now that the carbs are back off though, I decided to go ahead & order a new float to match the other new ones. Also bought a new float bowl drain screw & black wires for my coils (the yellow ones that came with my PAMCO ignition are obnoxious).
Other than that I’ll just do a fast idle cam adjustment & hopefully carbs will be ready to go again.
Now that I have another bike I’ve started thinking about more long distance trips. I never made it to New York, or Wisconsin—places I’d dearly love to to journey to on a bike.
Went over to Roadtrippers.com to plan a route and get an estimate on how many miles the trip would be, then plugged some info into the budget planner I made last year before leaving. Motojourneys are expensive. But compared to most other vacations, 1833 bucks is pretty good for a 35 day trip, huh?
If the coming of summer has you thinking about a long distance trip, you can find a downloadable version of the budget planner over at my “Plan” page here.
