I managed to track down the original owners of the bike this week. It took a little detective work but I contacted him on Facebook.

Confirmed it was his father's bike (and that he is 75 this year). Bought two bikes brand new in 2002. It has something in the vicinity of 1000 to 3000kms - the speedo cable was torn off and they put the Acewell digital on it.

They still have the other bike.

He also sent me this photo - and the accompanying story was "Like a week after buying it, dad followed me across a dam, I was on a pw50 so didn't even make a mark".

I used a section of pipe with a flat plate welded to the bottom.
Layed the bike over so the bolt was over the centre of the pipe and the pipe was hard against the frame.
Gave it a massive belting with a BFH.
It didn't budge. :eek:

What's next? Do I have to make a one-off custom hydraulic press out of steel and a car jack? Or a big "G" clamp? Heat?

Make a slide hammer like this?


:cry: I just want this donk out of the frame.

This might be a bit personal, but how big is your BFH? Does it require two hands to swing? If not, it might not be big enough...;)

My swingarm bolt was incredibly stuck too. I had to hit it really, really hard to get it out. I feel your pain.

I have a range of BF hammers. Up to Really Big F'n Hammers - ie: the sledge. But I'm fairly hip to what will budge something and what will make a mess. Particularly when I needed to hold a pin punch in one hand and swing with the other.

This is the Macpherson strut tool I decided to modify. I have one more job to do for a friend this weekend (replace her front shock absorbers) and then I can turn this into a swing arm press. :mad:

Just a few more pics.
1. Is this the factory installed piston? (part number visible 15100-5) No marks on it. No slop or twist.

2. Australian ID plate for Road Registration.

3. Engine serial #5012237 (model 501 year 2002 bike 237) - given this serial, can anyone shed some light on the engine internals, particularly the counterbalancer bearing/tooth profile before I split it open?

4. Going by the blue colour it looks like the SEM ignition has been reconditioned already.

5. Extra battery in a fabricated alloy sheet box. Neat job, only let down is that block of wood.

that is the OEM piston and as you may have read in a post near here, getting spares right is hard work! I have rings for them though. I think!!!!

the balancer assembly needs two special bearings which again i can do for you OK?

I've seen that blue hue before but I'm not sure what it signifies?

regards

Cool bananas! I reckon a set of rings and a bearing/pin kit.

I haven't seen a pic of the balancer so I'm not sure what the bearing looks like. This was the mod that I was told about by a local last week. I only just read the thread on it today.

The shop I was referred to was Valley Force Husaberg in Lillydale Victoria. Although it appears they have closed. If anyone knows those guys I'd like to be put in touch.

Also, quick question, part 800.36.020.044 - cylinder head. Ad says removed from a 2004 fe450e. Will this fit the 2002 fe501? Just noting mine has a 95mm cylinder and not sure of compatability between different capacity engines. My combustion chamber appears different. But this comes with what I assume to be an "08" cam.

I think the heads will swop but it is head and rocker cover COMPLETE you are looking for? you'll also have no oil feed to the head.

Mine is fixable (with welding the rocker cover, new valves, new springs, new cam etc).
This is already welded up, appears in ok condition and has an 08 cam.

No oil feed could be a problem though.

oil line to the head ?

I ran one to the exhaust rocker pin (08 head)
