hello All,

Sandblaster was kind enough to post the above pics for me,so I need to add some commentary to them. Here goes:

The KX is  street legal,in 1/2 mile track bike(not street tracker) theme. It's done in the racer's 'form follows function' strategy,to maintain the correct look,simplicity and 'fun factor' of a racer.

The KX /1/2 miler project began some 3 years back. After doing the wheels,suspension and radiator details,I shelved the KX in order to do 4 other bikes. A few weeks ago,I decided to finish the KX. The pic showing the KX on it's wheels was taken just before disassembly and shelving;all the rest are recent shots showing changes made in the last 3 weeks(I'm slow :-D).

The cooling system consists of two CR125 rads,which ,being thicker,have more cubic capacity than the oem 'barn doors'. I've added a third unit,thinking that it may be beneficial-won't know until it's plumbed and ridden. Regarding the plumbing,that's still undecided; I've read the different opinions for plumbing 'parallel' versus ' in line'. Suggestions from the modders on this topic are welcome;I think my radiator system will work, but .....lol.

I didn't like the looks of the rear mono-shock for my project,so I'm using twin Hagons by adding the mounts to my  4130n  tube subframe. The 'glass seat form matches that of the rear loop. It's about to be primed,and I'll have pics of it soon.

The air-filter assembly is presently under construction,and I'll have a pic or two of it in mock-up. It will locate off center to align with the carb,and use a round UNI filter held between two formed sheet metal end-caps,with 'quick-latches'.

Lighting- yet to be completely determined,but it will be minimal at best-just enough to pass the letter of the law......I'm researching some of the better LED bicycle lighting ;as whatever I use will have to be small and discreet(I don't plan to ride the KX after dark-several other bikes for that :-))

That's about all I have at this point......stay tuned :-)

Once again,thank you Sandblaster

I ran a battery only system for about 6 months.
It works fine but limits your range quite a bit.
Then I bought a MZB system from Alward25.
You won't even know it's there  :lol:
100 watts of power and it comes with different weights of flywheel.
I have the lightest version on my street tard and I really like it.
