Dear Massimo Yes I know all the figures The 912s is a magnificent it has a wonderful track record and can not be faulted . Just check the installed weight of a 912 does that include oil tank and the oil radiator and the water radiator. And all the pipes. When we are finished I will weigh the install...

Andy Cap Thanks for the compliments Yes we are taking this a step beyond serious as only enthusiastic amateurs can do. The tail in total is about 18 inches in die ou taal longer the lenght of the added baggage compartement is the tail longer . As I have extensive taildragger experience ZS-NAM, actua...

Dear Tailspin The price is directly influenced by the how much the owner gets his engine for but the rest that bolts on that is the gearbox and everything that bolts onto the engine excluding exhaust and oil cooler because that is instalation specific R45000. That means you can by a brand new GS1200...

dear Myr We have all the diagrams and the oil flow channels diagram the problem is that you still apply old air cooled rules to a modern motor. So far we have collectively 330 hrs test flying under some very harsh Hot high conditions. Both the engines running have temp probes on the inlet and outlet...

Dear Guest The BMW engine has no place to fit a mechanical pump. If you take the redundency at present you must be logical because you still only have one crankshaft . Therefore I use the Prat and Whitney example . If something mechanical breaks you go down. For that reason you do a total overhaul l...

100% Redundancy: How was this achieved? Very easy of all the critical items have two. Two plugs per cyl standard on the 1200GS Two injectors per cylinder Two fuel pumps electrical 4 Bar (the diesels have 1500 bar one pump) Two separate fuel filters and pre filter and main filter One battery optional...

Dear Gunter Thanks for the compliments the design philosophy is reliability reliability and again reliability. You know I've had an operation and I'm recovering well. So now I've started writing on what we've done . My aim is similar reliability as the Prat and Whitney in the PC12. We are working on...

The engine management system; Here we broke away for the BMW controlled system for the following reasons. The generic bike system is excellent but designed for the road and the modern parking and stealing environment. The original system has a transponder key, no proper transponder key no running of...

Choosing an engine: The first requirement is mass production. After a serious search all pointers showed in the direction of the new OIL COOLED BMW engines. The older generation BMW engines were also purely air-cooled as the air-cooled engines mentioned earlier in the project column. Here are some b...

Boet hoe gaan ek slaap. To all of you I have had zero pain I came out of Hospital Sunday morning . For six weeks I will have to take care of the hip. Meanwhile I'm writing and also working on the website for what is to follow tomorrow night . There is a small competition on with Boet Esteban and Wil...

After testing the springsteel undercarriage for the new Safari I found out that my own undercarriage was not up to spec compared to the springsteel legs of the Safari. Pain won the argument and I had a full hip replacement last Friday (highly successful) It does however make one slightly immobile an...

You cannot compare the R100 with the later oil heads. The R100 in purely air cooled with heat bottle necks and all sorts of vibration problems The R1100,1150,1200gs are completely different engines.If you are going to take the trouble converting then use the oilhead We have successfully converted wi...
