I had an original Honda diaphragm In my 2006 crf450r for at least 10 years before needing to be replaced. FYI you can’t use carb cleaner on any rubber carb parts.
Video definitely deserved a subscription, my quad is having this problem if I don’t punch the throttle it doesn’t bog if I do it dies or if I blip it. Hopefully fixing it solves my problem. Thank you!
I appreciate it the kind words! Yeah this issue drove me to the brink of insanity. Those accelerator pump diaphragms are trash. Just replace them every 30 to 40 hours and you should be good 👍
Dude, thank you. I just bought an ‘08 and I think this is the problem. I talked the guy way down because of it. Bike looks brand new, not a single scratch on it, but you have to slowly feed it throttle or it just cuts out. I was so confused because it has awesome power from a lug to the rev limiter, but you have to be so gentle below 3k or 4k rpm. Is that how yours was?
Yes! The accelerator pump is only responsible for the first snap on the throttle. The carburetor fuel flow will do the rest but it needs that quick spray from the pump in order to function properly. Goodluck buddy 👍
Same issue mine had. I ended up buying a new carb however, tons of green shit from ethanol fuel sitting in it for months. Figured it would be best to start new. $310 for a new one. I hate carburetors.
Man this is great thank you so much I have the exact same thing after a deep cleaning of the carb, I now just need to see how to take the accelerator pump out?
The Accelerator pump itself should be fine, it's the o-rings and diaphragm that go bad. Also it's extremely important to use carb clean and pressurized air in the Accelerator pump channel/nozzle. Goodluck
I bet this guy used carb cleaner and or used compressed air to blow out while the AC pump was still in place. Honda AC pumps are way better the all the aftermarket AC pumps.

I’m interested in jetting to throw in I’m having the same issues but my issue gets better if I change the jetting sizes

Question, it’ll idle, but want to give it full throttle it will die did yours do that?

@@22mpbwhere did you buy the new carb?
Man this is great thank you so much I have the exact same thing after a deep cleaning of the carb, I now just need to see how to take the accelerator pump out?
I’m doing this on my crf450x and the diaphram looks perfect but it’s doing the exact same thing and the pump is squirting
Did u figure it out cuz I’m in the same boat you are
So this guy im trying to buy it off says his accelerator pump is not working properly is that the same thing

@@Conspirotruth thank you!!!
Will this happen in high gears? The bog
The accelerator pump is only responsible for the first crack of the throttle so there's no delay.
that could be a jetting problem but not accelerator pump related.
Any recommendation LINKS on where to buy
Are you just looking for the diaphragm? Or the full rebuild kit? If you're gonna replace the diaphragm you should replace the o-rings as well.
Send the link that u used please
Im having the same problem

Cheap ethanol gas will cause this maybe use no ethanol gas
Hi where did you get the accelerator pump diaphragm
I need one

Did you have trouble starting you atv after you completed drained the carb
