ESE's works engine tuner

I think (Just as an idea) if you really did want to play with such a thing the compressor side of a tiny turbo would probably be worth looking long and hard at.

normal Turbo spins to about 140,000 rpm not the 11,000-15,000rpm of a small 4 stoke

would have to gear it up heeps

A hyperbar engine would solve all the lag issues. But create new ones

I would buy a XL100 first and supercharge it, then your FXR's would be in real trouble.

Supercharged Honda 50 http://www.elsberg-tuning.dk/the%20bikes.html

Superchargers.

The smog pump - cheap and plentiful. Used on automobile engines since late sixties.
The Aisin AMR300. From Subaru Kei- car - 660cc supercharged citycar.
The KF Max10- 25. American aftermarket blower.
The Hansen V12. Made especially for supercharging Kart- engines from 5- 20hp.

Thanks to TerraRoot for his post on the Blown FXR thread.

I have a new/refurbished smog pump off a big block chev.. I also have a reconditioned supercharger off a 660cc car, and I have a little tiny IHI turbo off a 660cc car as well. If you are serious about making a blown bucket you can have one. As long as I get a ride. The supercharger displaces 300cc/revolution supposedly.

Now I am torn, I have a RG50 rolling chassis setup with TZR wheels and was going to make a RG50 F5 racer. But a supercharged 100 is becoming realy compelling. I would need some Honda SL XL 100 engines and engine parts though.

In the 70s/80s I had quite a bit of experiance with Roots type and Shoric vane superchargers and have an idea of their potential. I would be interested in talking with you about the supercharger from the 660cc car.

Even if I make a supercharged 100, I am not planning on giving up on the two stroke.

Try Diesel Pig he has one I don't think he is going to use

Yep the excitment of talking up a storm sure keeps you warm. Looking for a Honda CL, SL, XR motor and/or motor parts.

Tomas thinks we have got a little off track here. He said that as the current GP125 is making about 20ps at 11,000 then the inlet port must be passing some air. He suggested we port a cylinder to the same specs as the RS125 Cylinder and the current pipe that was made to the old RM125 specs is designed to peak at about 10,000rpm. But the current 81 ATDC Exhaust timing is pushing the peak to 11,000.

He pointed out by changing the exhaust timing and dropping 1,000rpm we may not lose too much off the top if any by getting the power peak closer to the optimum revs for the inlet port-time/area constrant in Jennings graph. Also with the milder modern porting we will probably pick up a lot broader power band and even more so if we go on to make a new pipe in the modern style.

Today Tomas spent the afternoon looking at one of the spare barrels.

Pic-1 Tomas is blueing the barrel so he can mark the port heights.
Pic-2 the Honda RS125 Specs.
Pic-3 Tomas has used a degree wheel to set the piston position in degrees ATDC he wants and is scribing a line to show the correct port positions.
Pic-4 working from the top he cuts the port edge up to the line Pic-5.
Pic-6 working inside with a dremmel and riffler files bent to the finished angle of the port he blends the port edge back to the transfer duct to achieve the port (axial) upswept angle of 30 degrees for the main transfers that he wants.

There was surprisingly little metal removed but it was slow careful work it will take the rest of the week or so to complete it. Tomas says it,s most important to get the ports symmetrically even.

The other area to pay attention to is the MSV for combustion chamber turbulence and combustion dynamics and unmasking the transfers.

well i have a air-conditioning compressor off a yank tank i presume
i bought off a guy i met at a swap meet for $10 to make a compressor as i bought an older type tire changing machine too.
i sold the tire machine maybe 15 years ago.
I have had thoughts of supercharging bike engine with it but it has a oil sump and this other guy had one the same on his V8 powered landcruiser to pump up tires
that guy told me he had to use a special oil with it as your liable to get explosions.
it has a electric clutch on it.
I would think it was more suited to a sidecar or trike as the dont get the extreme angles that bikes get
you can have it if it cheers you up PM me if your keen

AH, This is great!

Teezee, can you ask Thomas if he knows "Hai" and "bong" (yea, yea, funny names) from saigon... (I know them well...been copying things from over here for a few years now, some of it mine....oddly enough, one of these guys used to live in the same town I currently live in......) Interesting stuff, him coming back from "Nam" with some very familure "techniques" (and ideas)

An Rs125 cylinder you say...... changed port angles?

I am fully impressed with the protractor used to measure the cut of the port angles

Ich habe nie den gesehen, der vorher getan wird!


I'll wonder if he has a new exhaust design as well

[TZ350]

I'll wonder if he has a new exhaust design as well

How many million people are there is Siagon? and how many motor scottors? I think he prety much understood all this before but was waiting for me to catch up. He's a clever chap, he managed to get to Indonesia when he was 13 and worked as an apprentice motorcycle mechanic, later returned to Vietnam to work with his father hand making watches and clocks before coming to New Zealand. He speeks several languages.

Yes he has a chamber design to try but everything takes time. The plan is:- Test bike as is for a base line and try a retarding ignition, modify and test the new cylinder with original RM-Spec pipe. Other projects are a new pipe and investigating alternative fuels like Shell 98, Mobile 1000 and Gull, straight and blended with Av Gas. Looking to retard the ignition some more and for better throttel response. Later when the motor is stripped to fit the new 1st gear we will be able to raise the primary compression.

Please don't take it personally Teezee, it's not aimed at you. I just read in one post from you what I have been writing (with broad hints rather than instructions) for the last 100 posts or so.

I have had a 2 designs STOLEN from me by some "dudes" in Saigon (and so have some very very very clever people her in Germany) and after a while it has gotten hard to swallow.

The guy I mentioned simply said to me

" We copy everything"

Lets get real though, is it really likely that some "guys" in Saigon came up with the techiniques you just photographed?

NOT REALLY.

Rant over anyway.

I will be interested to see what Thomas come up with.........

They did chase the bigest military power on earth out of their country with little more than sharpend bambo sticks. It would be a mistake to under estimate them.

They do have access to the net and can read SAE papers in English and French no problem. And there are a gazillion motorscottors to practice on.

Tomas is probably more concerned about you stealing his ideas for profit as although you have coverd a lot of material that is in the public domain you have shared very little of substance of your own.

He has consistantly shown what, why and how of every thing he has done, its the Bucketeer way.
