But fairly pointless bearing in mind the intrinsic design flaws of the 1/2 time engine principle.
Don't you look at my accountant.
He's the only one I've got.

This is the engine Drew has.
Oyster I think did the first this was one done after.
I reckon it needs a pitbike inner rotor as well drew and from memory the water pump was unfinished is that right?

Waterpump looks to be operational from what I can tell.
What do you mean about the rotor? Currently has the auto advancing ignition pickup from an XL on it. But ignitech is the obvious best upgrade for that.

Don't bother with a water cooled barrel for that - it doesn't need one. Just put a decent ignition on it and sort it.
that one i'm pretty sure was first built by Peter Lambert here in ChCh.

It was, although he didn't ever run it, still see him about but he's more into cycling and off road bikes now

Good to know. Your torque settings for the head on that fourteen are coming thismorning.
Should I match the timing to a VT do ya reckon? A CDI for one of them is gonna be cheaper that an ignitech is all.

Trad hondas other than the XR100 style have the auto advance on the cam.

Yeah, that's been grafted onto this head. If I go ignitech or VT CDI then I don't have to do the same to another head.
Goal is to get the timing sussed and tye bike running nice, then swap to a rear VT head to reverse port it...just because it's cool.

Which is why i sugested A pitbike ignition...........
Designed to run at engine speed as well so goes on the crank pretty sure it fits the earlier taper of the CB100 not so sure about the reversed 125S though

Hmmm. I have a pit bike motor under the bench. Will have a wee look at it tonight.

I've said somewhere else before that this motor did run - but maybe never raced. It was over advanced as the box used was for a crank triggered ignition - and it was being triggered by the end of the cam which had a c/f advancer. Two advance curves - one in the box, one c/f.....sounded painfully sharp.
I'd pick that a very basic curve would do well - at least to get it running and sort the mechanicals.
Ta
Righto then. I'll chuck an XL CDI in it and go from there.

If Oyster still comes on here he had a running version that won races, you could see what he used although it's likely to be a chainsaw ignition off something he had sitting around for a couple of decades, his had a cool frame as well

Finally got my ducks in a row and will try and cast something later today, there are lots of details involved, flasks , tools , safety gear etc.
I spent some time making some tools yesterday , tongs, a skimmer , a thing to hold crucible when pouring.
On Friday I went down to the local foundry and got a fish crate of greensand even though its black. In the last few months I have accumulated a bit of a pile of scrap so my first pour will be from some FXR150 parts and a few Petter pistons
My neighbours diary says I have boundary issues
Forum whore
Pour done, didnt go 100% to plan, but I have got one usable casting
the problems I had were i think due to the sand being a little too dry and making a mess of my mould.
The furnace was great and I melted way more metal than I needed.
The pour went well, with no dangerous shit going on
