Cylinder 3 not firing

[DanDeZinna]

I’m having the same issue but on cylinder #2! Going to go through the same steps you did! So far I have good spark and have compression. Next is pulling the carbs!

I hope you are going to do all the carbs since you have them off. I'm sure the rest will be just about as bad. I thought you said you had done a complete carb rebuild?

Yes, I did the rest. They were all messy but ok.

The reason I didn’t do the slow jets was that I thought they were pressed in!! Rookie mistake!!

The pressed in ones need to come out too.

They were not pressed…they had slots for a screwdriver!

Yes, but you left them in the first time thinking they were pressed in. The pressed in ones need to be taken out too for cleaning is all I'm saying.

Ahhh, I didn’t know that was possible. How do you remove them?

 

[Loose Chain]

Use a #2 threaded tap and make yourself a puller with a piece of #2 threaded rod.

Ok, serious stuff. Cheers.

Hey. Loose Chain. When you have the threaded rod in the jet, do you just pull it out?

 

[Loose Chain]

Run the tap in 3 or 4 threads to put some threads in the jet, then thread the rod into the jet, then with a washer under the nut, turn the nut like you are tightening it and it will start to pull the jet out.

Aaaah. Makes sense, thanks.

Hi all, I’ve done a complete rebuild and the bike turns over well but cylinder 3 isn’t firing (the exhaust isn’t getting warm at all).

I have checked for spark and all is good. I have checked compression and all is also good.

I did a carb rebuild (including new floats and jets) so my next step is to pull the carbs and check no 3 to ensure the jets are unclogged and there is fuel in the bowl.

Any other advice whilst I’m pulling them?

Sounds like ur pilot jet is clogged if float level correct.
