Hi All; New member, first posting. I'm looking forward to participating with others. I have a 1973 R75/5 (actually 1972 1/2, with longer swingarm). I bought new in Germany (domestic model, not export), currently has approximately 95,000 miles, all put on by me. I did through prepping in 1985 (change all fluids, oil in cylinders, empty gas tank and carbs, removed battery). Has always been garaged and kept under cover since. No rust, all original parts (except for SS mufflers which match originals design). I looked into cylinders with scope and no rust visible, I have very slowly hand turned it over and there are no hangups. I am planning to have all items refurbished, i.e. all engine seals, forks, transmission, electrical, etc. Keep the original points/condenser ignition configuration. Since I don't have the proper tools (or expertise), I will have a local shop do the work and register it as an antique here in Texas, no major, long trips. My question and looking for some experienced opinion is; since it should have premium leaded fuel (min. 99 ROZ) which is no longer readily available, which is the better option;
- when the engine is being rebuilt, have a thicker cylinder base gasket installed, thereby reducing the existing 9.0:1 compression (and dealing with the associated valve tappet adjustments and timing issues) OR
- use an octane booster/lead additive ( I have read the carburetor floats can deteriorate due to some additives ) OR
- any other suggestions/recommendations...
Thank you all in advance.
