My first racing bike - Jawa 559

We are all fans of classic bikes, so i guess you won't be mad of me for presenting my first racing bike. 1968 Jawa 559.
250cm3, two stroke.

In the beginning it looked like this:

From the major work, i would highlight:
-Remade owerflow canals
-Cylinder bored to 4th special
-On cnc boring machine made excenter for piston rod in order to get higher compression ratio.
-4mm bigger carb. (30mm instead of Jikov 26mm)
-Custom made exhaust specially calculated.
-From 6volts system, transfered to 12v.
-Removed dinamo, so it is "power loss system", driven only on power of acc.
-3 models of rear and front sprockets, changed from race to race
-Front fork from ČZ 477
-Rear fork from 175 Totica Jawa (Needed to cut the frame a bit to fit)

l'expérience est une lumière qui éclaire la main de celui qui la tient.
La théorie, c’est quand on sait tout et que rien ne fonctionne.
La pratique, c’est quand tout fonctionne et que personne ne sait pourquoi.
Ici, nous avons réuni théorie et pratique : Rien ne fonctionne… et personne ne sait pourquoi !
Nous avons deux vies. La seconde commence à l'instant où l'on s'aperçoit que nous n’en avons qu’une.
je préfère les mains qui aident que celles qui prient!
