Best 2-stroke engine?

[_STAIN_]

I have chosen another path as I find it satisfying to improve a dog.

a 3 legged one at that

[SS90]

iv got my tzr 125 well soon to be 100 and have got a frame for it now beter stop pissing around and get on with it 33hp power valved motor, down by one fith to 100 so 27hp at the 100cc mark in thery

That's awesome, best way to go (in my opinion) Great engines!

With-out trying to sound like the horsepower police, I think (from memory) the TZR125's where only good for 25 Horsepower (or thereabouts), and tuned ( with a special cylinder and exhaust, for as much as you could while still being useable on the road) was something like 30 horsepower (or so)


Sleeved down to a 100cc, in a good frame with slicks, I think you would have on hell of a fast (and still reliable) bucket!

Now I am real jelous. and absolutly green with envy.

Please post pic's and the development story as you go along.

What do you need pic's for you are the tz specilist so probley need you on board

That will be a TZ from the 70's I have found out recently that things have moved on since then.

I would try and get some pointers from SS90, I am looking forward to seeing how you get on developing your TZR100, it should be good.

Let's hope he does better than what he is doing on the fxr..

If you put the effort in like Nigel there is no reason it shouldn't be very fast. The only criticism I have of those modern 125-150 2-strokes is their sheer physical size. Nigels motor is a real lump compared to say an MB100 (my favourite). The drawback performance wise is the need to sleeve them down and also possibly like Nigels the need to weld up ports as they are oversized for a 100.

Yea, too right!

It's quite often forgotten that the fast 125 Japanese stuff really does have port size approaching "maximum", sleeving down to a 100 would require some port size reductions!

the ax100 is the best engine out there because you can do this

I really don't think they thought that through... 4 speed box, ugly ports etc.

Engineering wise it's cool. Practical? hmmm...

The Double Barrel of Hope : AX-200 twin
My Samurai – now the double barrel of Dream-Desire- Hope. Bit nightmarish as well. Almost two years since scratching up my Suzuki Samurai for a transform. She’s now getting dressed up to run a parallel graft twin cylinder engine & I feel bit confident (over confident?) that this time she would stand by me.

It all sparked with an Overdrive ’03-04 year edition featuring the legendary Rd-350 & Crazy Inline 5-cyl 2-stroke Millyard Kawasaki. Former has never been accessible let alone finding one. Few years later by year ‘07 my ten year young friend is due for a rebuild. I owed one for the tough time it has been with me in years of my studies & career start. First thought was to gift a shogun barrel, but the deep desire for an exclusive ride & a twin cylinder made me outrun such regulars.

Starting off in May’07 splitting the original engine, fired up the Twin engine for the first time in some time in March’08. Its few more months till September’08 for a road test. May be she didn’t like the silly idiot-engineered stuff, expressed so by splitting off the Crank itself. Its then time to hit the net & then my head and after six more months my bike is up ever so happily again with a new crank setup.

Thanks to many who assisted, special ones to ‘Gopiyettan & Titus’ always inspiring me to complete, share views & facts, tow the frame & what not, and above all tolerating my questions which at times even I didn’t understand. I must remember few colleagues for aiding me on the machining know-how front & the machine-service shop owners for caring to listen, do things as I required & never turning me off.

I’ve included few pictures of my dearest. Though looking not too good it is truly warm at heart! Think she felt pity on me for being on the verge of a job quit. No worries if she would stay pretty. It is quite much of a self assuring relief & a whole lot of commitment to have her smiling for years to come. Hope!!

I do have to add a lot of things to make it run around like proper twin. I expect generous inputs from you all techies to finish up. Shall detail all up in next posts.

Not only that, but that engine would be bloody wide as well!

Very cool.
