I'll second that!  :cheers: :cheers: :cheers:

The only question I have is have you tried the fit wearing a helmet and leathers. They tend to restrict how tight you can tuck yourself.

That bike's MY size. :-D

Pete, if he's too bulky he could always get "Freudian". :-o

I must commend you on the work you've done.

That is just awesome.
What you went through on the glass work is enough. :cheers:

Yes but I don't have pics. I took these pics with my tablet taped to a piece of plywood leaning against the wall. It's only got a 10 second timer. With my leathers on, I cant click the shutter and jump on and get into position that fast.  :roll: :-D

I'm OK with a wrench but this tech stuff is beyond me.

Glassed up a front fender but eventually decided against using it.

Don't throw that fender away. I can see where once you've run and found how fast you can go without it you may decide to explore the further limits with it. It looks smoooooth.  :-D :-D :-D

Too late. I tripped over it for the last time about a month ago. I am toying with another fender idea, though.  :evil:

The bike looks awesome. Tell us a little more about the body building process. I see you laid a lot of lengthwise strips but what did you fill them in with to get to the point of laying fiberglass? I hand built my own body too using foam sheets but it was a looooong process and I know there have to be easier ways.

Hey Sofa
  I was going to say that you have the wrong engine in the bike--- I read a little more and realised it is the Kawasaki.
  Fabulous job on the body-- pity you had to cut it to suite the class regs.
  Why don't you use the Honda engine, or is that the next step.
 I ran my rs125 a couple of years back and went 125. I'm 6'1" and can't tuck very well on such a small bike.
 This year my son went 105 on his APS-100 bike-- yz80 engine ( on our gps track in Aus and 99.7 for the record)
Will you be racing this year?   I'll be at BUB and WoS   maybe with my A frame bussa
cheers    Bones

Been a while.
Thanks for posting those pics, MTA.

Lots of progress has been made. Cooling tank plumbing is done. Electrical done. Brakes done (I've got a front master cylinder from an '09 GSXR750 hooked to the original RS125 rear disc - can we say "overkill"?). I'm in the process of re-doing the APS tail. I never did like it and it was too heavy.  Made up some nice, adjustable steering stops. Remounted the motor. Lots of little things taken care of.

And, I've finally come up with a simple mechanism to start the bike with the fairing on!  :roll:

My ported cylinder has been sent for Nikasil and I should have the motor in about 2 weeks. Then a custom pipe build and dyno testing.

The goal is 120+.

I've been too busy to keep up with this - 50 different reasons why.
I'd like to thank those who offered help with the pics. I hope I can thank you all in person in a few weeks.

Well, the bike's been in Gresham, Oregon for three weeks. Arlen Lehman at LED Performance has been doing all the 2stroke mods (you know, dipping parts in toad blood, swinging chickens around, stirring cauldrons, incantations and all that other voodo/ black magic crap that 2stroke guys do) and the results sound pretty good. After multiple heat cycles and a problem with the fuel supply he called and said it ran past 120mph no problem. I know that only the salt will tell and there will be lot's more tuning and jet changing yet to come, but after hundreds of nights in the garage, it's sure encouraging. At least my gear ratios are about right. If not, I've managed to track down a whole stack of sprockets.

I'm planning to run at one of the "test & tune" sessions at the local drag strip at the end of the month. I've owned a lot of bikes but this is the first one that I've felt I need to learn to ride. The power band is high and the CCs are low so launching is going to take some experimenting. 

Only a few hundred things left to do.

Good to hear you're getting there.
You're right about the voodoo on 2 strokes but you have to love them. I do.
It's premature but I wish you all the luck for the upcoming events.
Have a good one. I love the bike. :cheers: :cheers: :cheers:
