Oil advice and Recommendation

   The fork oil is just for lubrication, so actual viscosity is of little concern.
On my 1990 SPIII, which is essentially the same engine, I used semi synthetic 10W40.
EP80/90 for the gearbox and bevel. Modern oils reduce the need for Moly.

	IMHO It will work no problem but may need changing more often than a full synth/modern additive package.....personally I'd stick with full ester synthetic 10W50 (or 10W60) like Motul for the extra high temperature engine areas protection (pistons/rings/bores mainly). For Winter grade, although 20W is technically fine for down to -5C ish but it's getting close to treacle; 10W will crank (CCS) & pump (MRV TP-1) much better (faster) on cold mornings.....(I used to do arctic circle engine oil testing down to -40C).

	V1000 iConvert 1979. Hi, is there any need to shop around for a special ATF oil for the torque converter? I have read all sorts of recommendations including aircraft hydraulic oil. Cheers John.

	I don’t think so as they the ATF is only used for the torque converter and not to lubricate the gearbox or clutch plates in a car type auto-box. I used ATF Dexron II from Smith and Allan, at the last swap, you get 5 litres for around 20 quid. Of course I bow to the cognoscenti on the forum if they have greater knowledge.
