Last time I use Motul & recently just change to Penzoil but still having the same problem. Might going to try the 20W 50 engine oil as bro Alwi mention. but is the SIR-T gearbox also comes with LSD? Coz Euro R CL1 gearbox is with LSD. Scare the 20W 50 engine oil will not suit CL1 gearbox...what oil did you use?? i asked about the the syncro was around 600 plus..
By the way, you ask the syncro is around 600 plus is brand new. Right? The syncro is for 4th to 5th gear one. Right?
