    Looking good Kel... regarding Grant... hmmm no racing for Grant....He has more pressing things like working around the house. He still wears his leathers to remind him of his old racing days but they have a lace apron saftey pined to the front and the ass cut out were he likes to be spanked...!
    :spanking

    Anyway... dam the motor looks good..... thats lots of grunt... will it have a 12-24HP power band over 500rpm?
    If you need a frame... I might be able to dig up my old CG frame... perfect.

    Oh and to add... thats way to may calculations... my beer munted brain hurt just reading that stuff.
    If it helps the only thing I know about 2 strokes ... is BANG....
    One for the road...

    Grant, haven't seen you for months, are you coming to the track next weekend?
    So you would be the bastard that made me pay out some serious dosh. Tsk tsk.

    It just so happens i have that modified frame and swingarm (without the rest) sitting unused up in auckland now. It looks like you have the rest. Make me a nice offer and it is all yours.

    Husaberg is now a retired farmer or more likely just tired.
    He also has kids and a lady so is asset rich and cash poor.

    He also missed on the frame he was helping his child with his homework and missed the end of the Auction.

    I do like the look of your project though and I consider it a better starting point that the GP125.

    It also does seem to have nice close ratio for a trail bike.

    The inlet also appears less shrouded by the crankwheels than with the gp125.
    What is the Disk diameter of the KE125?
    The gp125 is ...mm its in the ESE thread somewhere, f'ed if I can find it.

    I would however be interested to see how power calculated by the sim would change with a 54x54mm configuration?

    Measuring inside a spare GP cover the disk looks to be 115mm diameter.

    TeeZee asks, what is the std size of the KE inlet port and the disk size?

    As I mentioned above the disk is a limiting factor, the diametre is a mere 106 mm. With 225 deg duration and a 50 deg port its good for about 30 crank horse power.
    The GP125 is better than the KE in most respect the exception being the clutch and gearbox.
    Before someone asks 'why didnt you buy a GP125', I picked up the original bike for $55 and a spare motor for $100, not too many GP125's around for that kind of money at least not with ESE buying them all up!

    Well I i'd be buggered.
    Why is it then the disk appears to shroud the crank wheels less?
    Is it the angle of the pic or are the crank wheels smaller diameter.

    Strangely the deck height on the crankcase also appears lower as well.

    Did i see a spacer plate in the pics as well.

    Could just be the angle of the picture plus the fact that the modified GP inlet is a lot larger so will exaggerate things further.
    Yes there is a small spacer plate as the KE doesnt have a large case volume. I was initially going to run a longer rod so I could increase the volume further but figured with the compromised transfer ducts a big suck pipe would probably short circuit the charge. Its try it and see stage, I have the option of another 5 or 10mm length in the rod if needed. DT rods come in 100, 105 and 110mm.

    Wasn't the main benefit of using a longer rod to increase the dwell, so the ports are effectively open longer? as well as the effective angle on the piston at TDC.
    There is a lot of other rod length options in between as well.

    There are several benefits to running a longer rod the main one with our engines being to increase the volume under the piston that is if the rest of the engine is designed to work with this. A properly designed pipe needs a large volume to draw from but the transfer design needs to exert enough control to limit short circuiting hence adding epoxy to the transfer ducts and changing the angles. The larger volume also introduces advantages in the rotary valve timing but I do wonder about the weaker carb signal off pipe? The days of the small case volume have well and truly passed I just wish I had greater confidence in my transfer design to fully exploit this.

    Interestingly Wob mentioned something about small case volumes for tighter tracks. Large for longer relatively speaking.
    Carburation will i guess be tricky with your intake duration anyway.

    Does the software you have, do gearchange cascades?

    Going back to the inlet pic. If TZ's intake is larger wouldn't you expect his to be less shrouded? The angle could be deceptive but it is still looks odd.
    Is the KE125 updraft?

    You got it the port tapers up with a slight kick at the crank wheel. The other motor which has a larger inlet has been straightened like the GP125 so as to maintain the width height ratio.

    come on a KE motor is worth 5 times what a GP100-125 motor is worth,KE motors 12 + GP wins GP100-125 GP wins big fat 0

    No understandy what other engine? Do you mean TZ's suzuki gp125 has been shaped to look like a er... Suzuki Gp125
