Did you get to meet the Viking lad selling them @Vintage Grumble? Tried to palm those off to me after sending a lot of messages asking for help and I still haven't replied. 

Dodged that bullet. Yeeehaw. 

Haha, yep he mentioned you a few times. You should be safe, he no longer has any small bikes. He was a nice, but slightly odd chap.

He's gone full sustainability and looking into communes around NZ to join. Good times. Welded a few of my bike things up before. Good luck with the bikes. Do a big Suzuki skid!

I can't imagine how fast the 650s are, must be nuts.

Edit: apparently with the correct technique, they can do 0-100 in 4.6 seconds.

Edit edit: last night I found out why the back wheel of bike no2 was never changed to the OG wheel, the later model motors have a way shorter output shaft, and the OG brake/wheel combo doesn't fit.


I'm going to yank the final drive shaft out of the bung motor and see if it will fit in this one, because I'd like matching wheels. Not the end of the world if it doesn't, but worth a go.

Yeh so the final drive shafts were the same, just different in the dingus length. Swapped that over and bam, matching wheels. Also wanted to run the correct muffler, which involved changing the gigantic bracket they hang off. The skywave muffler has 3 bolts vs boomermans 2, and sits on a very slightly different angle, so also had to change the little header pipe. 



(Note finger in shot, like a legit boomer)


Then I put it all back together using the best bits of both bikes. Note $17 AliExpress shield extension, and burgman forum badge.




I dailyed it to work for a couple of weeks, goes hard for what it is, but sadly I'm too tall for it, it just owns my legs and back, because I can't get my ass back far enough (note removed lumber support in attempt to move ass back) so I'm going to have to move it on. Bit of a PITA, but hey, what's a brother going to do?

I had a bit of free time, so started playing with the skywave. Determined the fuel pump was not dead (as last owner was told by mechanic). It had spark, so figured out the wiring for the pump and sender (had been chopped off) and wired it up. Then after a bit of fooling about figured out it was just a bung relay stopping the pump and injection. Changed the relay out and bam, started straight up. Stoked. I went back later for more mending, and every time I hooked the battery up, it would blow a fuse (had a few blown fuses before I started playing around) after blowing a few more, I discovered some wires shorting out. Sorted that and no more blown fuses. But now it won't run, dumb. It's flashing the F1 light, which I think is basically the check engine light. Also the dash lights flicker randomly, so something somewhere is not happy. While trying to find a wiring diagram, I found the actual bike on another forum. Good to see it has a long history of wiring faults, lolols.


Hopefully I can sort it out, as I have to flick this one off too. I might even be able to break even, ha.
