2 Strokes Down Under

I have a colour scheme suggestion

Its been a busy couple of weeks.

-I've been doing the many remaining odd jobs to try and get the bike ready for the dyno on the 23rd of Jan.

-I've restored the jetting back to OEM which required a few needles and jets.
I think now she is running a 170 main, 48 pilot, NOZH needle 2nd clip and a #7 slide for sea level riding.

-I also spend some time building a little guage cluster this week which includes an EGT gauge, a coolant temp gauge and an LED bar tacho.
It all came together very cleanly.
The EGT probe is installed in the header, 100mm from the piston face.

-The front subframe was finished off, It is now very stable now and the faiing can be removed in 30 seconds with no tools which is great.

- The Servo motor system was installed and completed, the sub exh ports locked open and a new Z dimenson was found.
The servo motor controller was then programmed with maximum and minimum openings and a progressive curve.
This took a few hours as my servo motor was fried, luckily I had a suzuki gsxr750 exup servo to use a spare.

The only remaining jobs to get her on the dyno are:
-having a CNC radiator cap welded onto radiator as the system is currently sealed.
-adjust the chain
-copper sealant the exhaust header/manifold interface
-sort out why my CNC gas tank cap isnt venting


Hopefully all goes well in 2 weeks!

And then?

yeah, I got everything finished and had a full day at the dyno booked in.

But the bloke who was going to lend me a roller starter pulled out so I had no way to start the bike. So the dyno day was cancelled.

I will be popping it on the KTM werribee dyno in a few weeks instead, there dyno has a roller starter function.
I also am looking at whether to buy an Easy-Starter roller starter for $720, or hooking a kart starter (hand held) up to the kick starter shaft ($350-400)



In other news, after a weekend at the island classic, I have decided to enter my Mito into pre-95 racing as all the components were available pre-1995 or at very least they were visually indistinguishable from components of that era.

I made my own kart starter from a Camry starter motor.
Cost me $108

You can make a track starter out of a variable speed grinder and two rollers and some off cuts of steel I actually used a large polishing buffer because it had variable speed and was the cheapest thing Bunnings sold that would do the job. Then you just need a large light switch button like they fit to old peoples houses so you can foot operate it.

I do like the Camry starter Jeff the latest lipo batterys REALLy get the starter motor moving, and Pats buffer should work a treat as well, a 9 inch angle grinder spins at 6000 rpm. Hmmmm decisions decisions, thanks for the inspiration

just bought my paint... ferrari rosso corsa

Have been busy in the shed every night this week bogging, sanding, primering...

Smmmooooooooth!

What numbers did you get

cant quote top end power yet as jetting was way off.


But it made just shy of 30 ftlbs at idle and 46hp/40 ftlbs @6000
perfectly linear from idle to 6000, no 'coming on the pipe'


just need to sort out the last 2500 rpm, where it falls dead between 6000-8500. I think its mostly jetting as the EGT was very very low.

Changed jets and had another run, but a backfire broke 3 reeds, which ended our day

Yes, it made a sweet sweet noise, then farted through the carby and that was that, no more smoke.

Onward and upwards Jeram. Gives you a bit of time to clean the oil off the undercoat (?) and then me a bit of time to make it red.

haha yep.

Damn the bike looked good in white tho!
its very tempting....
