BMW F650 HP1

Today I picked up the frame from the powder coating workshop. Iā€™ve decided to paint it blue like other High Performance BMW bikes (HP2 and HP4) Canā€™t wait to put bake the wheels and the engine on this bike ! šŸ˜

Today I put back the clutch on the engine, using the BMW tool to center it to be able to put back the gearbox on it. The particularity with the flat-twin bmw bikes is this clutch which is Ā«Ā dryĀ Ā», like on cars, in opposition to wet clutches as we can find on most of the bike. The engine and the gearbox donā€™t share the same oil.

Yamaha FZR 1000 Quarter Mach

I bought this wonderful FZR 1000 from 1989, first model with the Exup. The goal with this bike is to make it look how it was when it left the factory in 1989, because some fairings are a bit damaged... Concerning the mechanical parts, Iā€™m going to put better brake system, improve the suspensions, front and rear. Finally, concerning the engine, the goal is to prepare it to have enough power to reach Mach 0,25 (about 306 km/h at sea level). For that, Iā€™ll have to reach about 180 hp, knowing that for now the French version is limited at 106 hp and the full power version is at about 145 hp. Iā€™ll make dynobench test at each step after putting new parts to see what has been won in term of power.

Today Iā€™m remounting the rocker arms. I used special remounting oil which is like jam, which will stay to lubricate until the first start. I also used Motul 300V 15W50 to protect the steel parts from rust. The 4 rocker arms and their axles are brand new, bought in Germany. The fixation are also new, as the pushrods. I found these adjusting screw which are lighter and more easy to handle when valve adjustment needs to be done.

After checking the different sources of failure, it comes out that itā€™s the rotor/ignition sensor woodruf key which was broken, leading to wrong ignition spark timing. The problem is that it damaged the crankshaft extremity, so I had to buy a new crankshaft, and Iā€™ll have to disassemble the entire engine šŸ¤¬
