I know you have said that all the engine work is "top secret" - which adds to the intrigue, but once it's finished are you going to release all the details - to the magazine and to the wider world?
How much longer do we have to wait, btw?

To be honest, the magazines aren't really interested in engine specifics... They just want something that fits their readership... Is it fast, is it fun, does it look good, and where to get the work done? I doubt I'll ever release everything that has been done because if everything works as desired, this will be a engine to remember.. And, the members of KX Guru Race team have told me to keep my big mouth shut  :-o

Most of the things done are in line with what we call the standard Team Green port mods... All that has been well documented...
Since this is for a MX track I can't do a desert port timing change. In fact, we cut .030" off the bottom of the cylinder and lowered the port time to make it more tractable power.

It's the things that I can't discuss (YET) that will still make this engine perform very well on top...

When will this be done? I'm not in a big hurry as I have several other projects I'm also working on but I'm hoping to have the bike assembled and broke in by mid February 2019. I can't guarantee it but that is the date Jason and I am working on.
Likely the graphics won't be done by then but you should get a very good idea of where we are headed by then.

Thanks for going to the lengths of explaining how things are going. I understand the need for secrecy surrounding the KX Guru Racing Team - every tiny little engine mod can... well, not so much up the power, but it's the delivery of that power,, and the engine's overall characteristics, that count. I do know, from my own days tuning 2 strokes that when you're (literally) at the cutting edge of port shape, timings, skimming of head and barrel etc, it all makes a difference.

It's always interesting following a build from beginning to end, even if like me, you come to it so late.
Things always seem to take longer than planned too. You mentioned mid-February 2019, and it's just a guess but I bet you're running a little late?

With regard to the magazines you mentioned, since buying the KX and looking online for photos, I’ve noticed that a lot of the mags are style foremost and motorcycle second. In some cases the bike is just used as a clothes horse – a fashion accessory that’s “macho” and “cool” for men. Motocross bikes are turning up with modifications in men's mags. I've never bought one but I have flicked through them in waiting rooms etc. It is always more about the clothes the bloke is wearing and where he can buy them, what label, how much etc. A good example of this is how "cool" it is to have certain names and labels on the clothes. Ha! Think I’ll start a thread along those lines.

Lambretta clothes hit the jackpot, because the name was not even registered when they started, so they took it from there and now it's huge. Bultaco is a name that's cropping up on clothes nowadays. Triumph is now collaborating with Barbour, which means they now charge $999,00 for a jacket worth half that! I remember when we had waxed motorcycle jackets made by Belstaff years ago. Well, those smelly, old black wax jackets went out of fashion for a while and Belstaff went bust, only for an Italian company to buy up the rights to the name and start recreating the look in supple, expensive brown leather etc. What a great move, financially speaking. But it just seems that genuine bike stuff simply gets exploited because it's "cool."

Even more pics please!

Cole Townsend at Fasst Company really outdid himself with these pegs.
The quality is unbelievable.
It has the elastomer which isolates to cleats from the peg.
Check out what they say on their website:

Absorbs vibration and abuse.
The elastomer absorbs vibration allowing your feet to remain better planted on the pegs. High-frequency abuse like spikes, jolts, and bumps are also dramatically reduced through the cushion of the elastomer.

Exceptional traction
A combination of our tooth profile coupled with minimized vibration, and larger platform (77mm x 58mm,) literally grabs hold of the bottom of your boot.

Hard Anodized 7075 T6 Aluminum
Provides exceptional construction, strength and wear resistance.

Orange, Red, or Blue to suit you.
All Impact Moto Pegs have a black body with either orange, red or blue elastomers of your choice to suit your personal touch.

Add your name, number or both to your Impact Peg.

... check these babies out..  :-o

Nothing is set into stone but we are getting closer to being finished.
The engine is assembled, all the new mods have been tested mechanically and they work great.
The real question is how well will the mods work together???
We will see soon enough  :-o

Had a great time at the Eugene Expo last weekend.
Jason Tanner at JT Engine Works and I shared some floor space.
I can Honestly say that we had the two nicest 500cc 2 Strokes there  :-D

Something cool showed up from Alex Ward at Crazy Al's Racing..



But, it won't fit  :x



A trip to my semi local KTM dealer and I found another tray with a perfect box size..

Perfect....
And there is enough room to do a 24V conversion of this battery isn't enough  :-o

You most likely will want to do the 24V conversion. I've had the exact same battery on my CR500AF conversion for almost 2 years. I've got the 63cc dome insert coolhead on it also, so it doesn't start very easily when it's cold. Most of the time I have to kick it on first startup. Starts easy afterwards when it's warm. Probably the combination of the large cylinder volume and higher compression with the coolhead. I'm also not running a compression release.  I'm about to convert mine to a 24V system using the SC-1 batteries - probably a better way to go. You may earn some brownie points with MXA when they barely tap that start button too  :-D
