39pwk dump size

[sheerider11]

so even after everyone advised you to buy new, you bought used and now you're having issues, and don't really know what you bought?

Lol.

I love being able to tell people I told you so.

Post a pic of plugs. Are you sure there isn't an air leak that could be causing the sputter.

New carbs would not solve my problem

I know every motor is different but I will be running my 421 with 39s and my dump is at 120.

So buying new and KNOWING exactly what you have, having a BUILDER set them up specific to your application, AND having a person to CALL right now who can help you wouldn't help with your problems??????

 

GET REAL

Pump is not needed on that motor for 300'

1. I don't have a builder

2. I've already called two places and they didnt help me.

3.every motor and application is different so its not like they're going to set me up perfect. Only close. Hell I'm close right now

1. That's your problem.

2. Because they didn't set them up. No one with any sense would help you blow up your motor and put themselves in that spot.

3. They'll get you closer then people just guessing. They know there own work.

"Setting up" alky carbs isn't rocket science. I don't see why a builder has to do it. Drill, change needle, install power jet and be done. Sure there are some other things that can be done but most don't do that any way.

I'm stupid simple and setting up carbs is not stupid simple. There is a lot to it. And I use a pump on ev thing

I agree, but this guy can't figure it out so he should have paid a builder to do it.

Could be electrical if it's sputtering and its washing the plug. You should be close enouph to make a clean pull

[locogato11283]

Just to add some info, I didn't need a pump on my 24DM at LSOK last year. I doubt a 4mm Cub needs one.

Every bad CDI I've ever seen caused a high RPM miss or sputter. The bikes would start, idle and rev up clean but once they had a load on them they ran like shit.

 

Good call on electrical.
