Re: Recaro backrest cable change problem
Got it done, used a bike gear cable and connected it with the good part of the original cable, it can be done without cutting in the metal of the seat.

Re: M30 intake manifold
I am in Belgium and I am interested but shipping will be huge, I found a 2.5/2.8 near me but I do not know if it will fit.
The M90 is the same as M30 for external parts.

Re: 1980 Euro 635 CSIA
My piston are grooved vertical from bad oil maintenance and driving hard with a cold motor, pistons expand quicker than cast steel so they grip to the cilinder wall.

Are M30 valves the same as M90 valves? I had a leak in cilinder 1, the inlet valve die not close, I thought it was some dirt from the disasembly, but after cleaning the valves intake nr 1 is not closing, it remains open about 5mm without springs. The valve is bent. I lapped all the other valves with...
