Good on ya for tackling the job yourself :-)

Sorry I couldn't be there, it's a nice learning curve and to get a better understanding of how the parts etc work.

I agree, this is the best way to get to know your bike  :thumleft:

Problem #3: Engine Rebuild

Looks like that play is from the crankshaft main bearings that are finished...

I truly hope that this is not the case  :-\

I wonder how does something like that go finish or "klaar"? Is it something that commonly gets serviced or replaced at some stage?

The play on the flywheel is most certainly an issue, as it hangs directly off the one end of the crank.  The crank should definitely NOT have that amount (or any) play, so my guess would be, at minimum, new crank bearings.  Hopefully the crank itself is still ok.

Seems that things turned out for the better (really thankful for this). The bit of play on the crankshaft/flywheel is apparently normal according to the manual of the bike - 0.30mm to 0.50mm tolerance allowed. We did ask for an opinion at BMW Stellenbosch, so the alternator also has a small bearing that counters for it. We should just monitor it but for time being, the bike must be ridden and enjoyed!

The new stator was fitted and indeed working as confirmed today with @ravingDIODE voltmeter - the alternator is finally charging the battery!

The next challenge is to get a new bike stand since it broke off. I know of Rockfox that specialises in stuff like this, will make a stop at them to ask if they can assist.

Now to get my confidence levels back.

Now you must just go and enjoy the bike  ;)

Great to hear - if I have not mentioned it before you need to remake the sidestand using the plastic foot and the cast iron hinge from the original. Use thicker wall stainless steel pipe. Easy fabrication coping the OEM. There are no aftermarket solutions. Grind off the lip on the flange that activates the idiot auto retract before the bike falls over on the Ferrari.   >:D

Mine is definitely aftermarket, not OEM since the invoice for it gives it away:

That is either custom made up or converted ... some bodge job - got to love the piece of axle iron welded to the bottom to get it to height, real feat of engineering finesse.  >:D

Agreed, the bike is quite on a leaning angle when the stand is out - not really upright. And with that axle iron, it just sinks away in grass/sand. I'll get a quote from @Mike Adendorff somewhere next week if he is not too busy.

If possible try and get an old broken one to use the cast hinge. Must be someone who has bought a new one and maybe has the old one still?

Had another small mishap with the bike - the clutch cable was done and need replacing.

Went to Cable Super Service in Woodstock to get it fixed. The cable was a bit too long at the start, so we needed to revert back to shorten it a bit.

Afterwards, we stopped at Flying Brick where we had a nice chat with @zebra - Flying Brick providing valuable information and stories around the G450X and the underrated F650 Twin.

The bike is up and running again and we quickly popped in at Trac Mac to get a new oil filter and spark plug which will be fitted somewhere next week.

I and @ravingDIODE will hopefully try and pop in at Mike tomorrow if all plays out, but ride we will, so looking forward to it.

The bike is at least running and hopefully, we can tackle a Paarlberg trip so that I can improve on my off-road riding.

There are a few fixes that I need to adjust on the bike:

1. New stand which we hopefully can get sorted before the end of the month.

2. Fitting of new spark plug and oil filter

3. New drivetrain since some of the teeth of the rear sprocket broke off (front and rear sprocket with a new chain) - will also get the correct ratio for the front that will be better oriented for the longer trips as suggested by @zebra - Flying Brick

4. Speedometer is not saving my trips - I presume that the speedo is operated with a cell battery that needs replacing, will look into it.

Lekker bike you got yourself Andrew, that thing must be joll to play with in the veld.

As you mentioned early on in the thread buying second hand can be a bit risky and you can easily end up with a lemon when you thought you were getting a peach.

Hope you're troubles have come to an end now and you can enjoy many happy miles with your buddies!

Yes, the speedo has a small coin cell (CR2032, if I recall).
