Today I had to run around to get some suitable material, buy some stuff to eat, let my helping friends know that you want to put their stickers on the liner, bring my tax documents to my taxman and finally get back to work. I made the front spacer 0,04mm eccentric as the front crank was out of round by 0,08mm. That crank was running true on the bearings as well so probably the same cause as on the back end. As the roller bearings were shrunk in so tightly I didn't have any clearance on the rollers so I had to grind both inner tracks down 1,5 thou. Front spacers slides in just as nice as the rear, finding the correct position is as follows. Nip the crank nut up until all play is gone from the timken bearings. Grip the spacer with a big wrench and turn around each direction until it starts to bind, mark each position, middle between is the correct spot and maximum even play all around the bearing. Will put the pin in the front spacer as well. By coincidence I had the rear spacer length totally correct without measuring - the blower pulley sits right where it used to be. The front spacer is still 1/8" too long. So I guess I can start on putting the big cover back on and drill and tap all those holes. All the gear drive is just fitting the two covers with 1mm to spare so no work on the starter yoke needed. It will stay where it was before.
This morning I talked to Mr Baier - the piston coating guru. He is a one man operation as me and very friendly - he has worked for BMW F1 to get them engines reliable, has done 30 years of engine tuning and preparation for speedway bikes and is still coating pistons for Porsche�s works racer engines amongst almost all Moto GP pistons of the current race teams. After telling him what we do and what I want him to do with the pistons he said he will make me a special price if I put one of his stickers on the bike - I agreed. So I will send all 4 cylinders and a set of the best pistons that we have to his place and let him work his magic.
