Bogging

Postby w4anp » Sat May 23, 2015 10:43 pm



I just finished overhauling my carbs and got my bike running. The bike didn't run when I picked it up so I don't know if the problem I have is new or old. The problem I have is that the motor boggs when you go past quarter throttle. Any ideas on what could be the cause?

Did you make sure to sync the carbs after overhauling them? Even a bench sync will help with the bogging down.

Did you check/set the float level?

Sure sounds like a fuel issue..floats, jets, 1/4 shouldn't be a synch issue that's only at idle. More info needed..how is she at 3,000, or 4,000 rpm's, what do the plugs look like. will she run out to red line OK???

I did sync them and set the floats at 15.5mm. Idles great and all four cylinders are firing. At 3000 to 4000 RPM is where it boggs the worst and 4000 to 5000 it starts to lose RPM. With the bogging I haven't been able to hit red line.

I installed new plugs before the run but I haven't pulled them yet to see what they look like.

sounds like a jet or slide issue...jet clogged or slide(s) not operating properly..due to lack of vacuum or sticking.

another possibility is bad battery/alternator/coil issue..at higher rpm's spark is not strong enough..

If you take it to where it just begins to bog and you give it some choke, does it pick up any RPMs? I had exactly the same issue but mine turned out to be the float levels. With it running just where it was starting to starve I gave it some tiny spritzes of starting fluid...it would rev right up when I did that. Maybe it would help to determine if it's a spark or a fuel issue?

It really sounds like a fuel issue.....some possibilities (since you said the bike wasn't running when you got it). Dirty fuel filter/plugged petcock/dirty& rusty tank..or..low fuel pressure due to a bad fuel pump

Ok guys, I found the problems. Yes more than one. I pulled the carb rack off the bike and started looking for "funny stuff" and found the the piston in the #1 carb was getting stuck. It was happening because the VC when screwed down was not sitting flat. Such a small amount that you almost can't see it. The second problem I found was the ring the holds the piston needle into the piston came off and wasn't lifting the needle when the piston moved. That was on the #3 carb. So with only two working right I'm shocked it even ran at all. Runs supper great now, thanks to you guys for pointing in the right direction. Without your help it would have taken a long time to get right, thanks again!

Dave
