That's a common problem. They always bend.
Very simple fix.
Just be aware that the exhaust pushrod is longer than the intake pushrod, so you have to order the right one. Maybe just order both of them, in case the intake one is also ready to go. They don't cost a lot.

Yeah, it seems like a pretty straight forward job, but I don't get the parts before the temperature hits below 0c in a couple of weeks...

Is this a common problem that is caused by itself, or is there another problem that could have caused this one?

[Arizoni]

I don't think it is a "common problem" but it does happen occasionally.

As the pushrod that failed is the exhaust pushrod and this is longer than the intake pushrod, it is possible that someone replaced the exhaust pushrod with a intake pushrod.

If that was done, the adjuster would have been screwed out further than it is supposed to be to get the valve clearance into spec.  and that could have caused the failure you have.

If you are in the US, NfieldGear should be able to get replacements to you within a few days.
Their catalog shows the screw adjusters as a seperate item so look at what you have to determine exactly what you need.

It's best to call them on the phone and talk to them.  They are experts in this area and can tell you exactly what you will need.

The push rods are available with Metric or British threads on the adjusters.

 I would order the British threads. Larger diameter threaded portion than the metric push rod and more correct for your ( British thread ) Bullet.

My 03' did this when i "pushed" the performance envelope a little too far. I got lucky, the pushrod jumped out of the rocker with no damage so i just pulled the tank and rocker cover, re installed and adjusted the valves. I was back on the road in 20 minutes . Good luck.

REs downsizing of the quarter inch pushrod adjuster thread to the 6mm metric near equivalent was cheap but dumb.

Very Volkswagen!

I'm jeaouleus of you who can get this parts in just a couple of days. When you live north of the artic circle, things tend to take more time...

But I ebay'd it, and I hope it won't take much time

NewOne,

 Did you get your Bullet running yet ?

[Tarnand]

Hi NewOne,
I am also using 389.  I replaced it 5 years ago together with the exhaust and intake.  The carb was jetted by Hitchcock accordingly: 

• Main - 240
• Pilot - 30
• N/Jet - 106
• Valve - 3.5

For carb fine tuning I followed the standard Amal instructions you can easily find on the Internet.  Anyway, if you think you are still going to have questions please feel free to ask. 
BTW, good luck with your new bike.
