ESE's works engine tuner

[Drew]

I see a fly in your ointment drew the MVX has a 48mm stroke...
Maybe a Aircooled 125.........

The extent of work in this crank, replacing the webbs with Beat items won't be the end of the world.

You might as well fuel inject it as well. You double up what Rob has. You'll need the 250 chassis to fit the wiring in. Good thing is the 250 alternator will supply the needed ergs.

I can see it now - watercooled 100cc twin, 15000rpm, fuel injected with 2 injectors/cylinder(minimum).

6061 T6 is a good all round alloy for machining engine ( and autogyro ) parts.
I use 6061 T6 351 to make autogyro rotorheads amongst other things, good strength, good corrosion resistance, machines very well, accepts anodising well.

Thanks Flettner, sounds perfect. Where do you get your billets?

I can't tell if you're being serious.

I would be using the 250 chassis, it's just had a VFR750 fork conversion and is getting a CBR600 swingarm and suspension. To allow for proper sized wheels.

I've chopped off all of the standard engine mounts unfortunately, so might have to hunt down another roller. Luckily, not too many MVXes were written off. They tended to blow up before anyone made it to the twisty roads.

Size of the thing is my only concern really. They're a wide bit of kit!

I have a friend that rides his MVX every day - so if you guys get bored thinking of ways to ruin one, then remember there are a few people
out there that need the parts for a runner.

I get my alloy from Nalco, good people to deal with.

My brother has a runner also. Chap over Coro way from you has about enough bits to make five of them.

Try Nalco, Wakefield Metals and Special Steels. Ritchy at Trimac in Penrose has off cuts he sells.

Thanks Gigglebutton. I'm in Wellington, so has to be mail order. Nalco are assisting me with my enquiries at the mo...

For something different.

Anne has a F4 Honda 125T she races at Mt Wellington and a girlfriend challenged her to a drag race at Meremere this weekend.



Not sure the friend expected her to front with a 1200 Harley, but why bring a knife to a gun fight.

A bit of time spent on the dyno sorting out which gears to use and the best one to start off in.





Just out of interest, a comparison of my 2T (the Beast - blue line) with the Harley.

I think you had the final drive ratio entered incorrectly. It's a seriously wanked skirtster that'll pull 200k's, and sixty ponies suggests otherwise.

Hmmm yes I see what you mean, but no head wind on the dyno to hold the bike back so the Harley just keeps spinning the drum until the rev's top out, in real life it would have to fight a head wind too.

I would have thught it would be bouncing off the limiter before 125mph still.

Smooth curve though.

Its pretty good for a stationary pump, i thought they didn't get much more than mid 50s, but that was a while ago, not that progression has probably been more than glacial. Back int he Dyno-tech days Chris was doing a few, but the word got around that his dyno read low & Scooter-centre got one that read closer to the 'proper' numbers so everyone was happier. Chris also had an unfortunate habit of testing things, like removing the Gen-ewe-swine Raped Budgie(TM) parts like the Thunder jet etc that they'd just laid out money for & gaining power. Clearly didn't know what he was doing.
