I do not believe the R4 is the same family as the 5w-50. I will forward whatever info I find.
Castrol RS is (or was) a pure synthetic with similar synthetic ester technology to Motul. R4 may be something quite different, I'd say 'read the label' but certainly Castrol is one of many oil brands now in the UK who (surely deliberately) do not make it clear on the label when oils are in fact part-mineral, not 100% synthetic. Very annoying.
I have a complete (essentially) barn fresh T120. It's a 1972 OIF Bonneville, with a variety of extra parts, and I was planning to advertise it locally for about $750. Would likley negotiate a bit with anyone from the list.
Er, how much for shipping back to England ? :-) I've got a few relatives in California, but I wouldn't dare ask them to help out with that one!
P.S. If "original" matters less and lack of headaches matters more, and you like the concept of a Bonnie--buy the Kawasaki imitation.
Very sound advice. Or even the Triumph imitation! http://www.triumph.co.uk/site/bikes/page.cfm?BikeID=64
Does anyone out there know anything about Valvoline syn. blends?
Nope, but as the subject of Brit iron has come up, I can say that Valvoline 20/50 was the oil of choice for the better informed Brit iron riders of the seventies. Motors always seemed to run quieter and last longer (hey, it's relative) with Valvoline - that was before synthetics were invented, of course, way back when I was young!
The Futura [ . .] stock motor reading about 100rwhp according to some of the dyno reports and more to be had with a exhaust system and fuelinjection remapping
The Futura has the very complex Sagem adaptive engine management (like the modern sports Triumphs). According to Jorge "George" from Renegade, the Aprilia v-due Mille (up to 2002 model anyway) uses a Nippon Denso f.i. system, the ECU of which looks just the same as the GTS one, apparently even the circuit board looks near-identical - except that it has a socketed EPROM instead of the soldered-in ROM! Various teams who have raced the Mille must have the knowledge on how to re-program the ND system, though I doubt if that knowledge will ever reach GTS riders! ============================== David Thurgate (for Name-Shop) http://www.name-shop.co.uk/ [EMAIL PROTECTED] / [EMAIL PROTECTED] +44 [0]20 77035349 +44 [0]794 1158849
