KTMito 380

I have a colour scheme suggestion

[Jeram]

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?

[Jeram]

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

Smmmooooooooth!

What numbers did you get

[Jeram]

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

[fred99999au]

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.

[Jeram]

haha yep.

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