I was at the dealer today looking at possibly buying yet another clutch. I have an EBC Heavy Duty clutch in my Scrambler now that has seen about 15,000 miles so far. It seems I've had clutch issues ever since I did the airbox removal and started with gold clutch springs. I was told by a mechanic who will remain "unnamed" that a former "unnamed" mechanic put the wrong springs in my bike. The gold ones. This came as a relief as I had been puzzled by how abruptly my clutch would engage towards the end of letting it out, and it would also not engage quickly enough. Now, I never knew this but it said in the catalog that EBC heavy duty clutches are NOT FOR USE with full synthetic oil. Can anyone help me here? I'm thinking of going semi-synthetic. Nothing else has ever seemed to work with this. The best ride was the stock clutch and springs, but of course it slipped at 70-80 MPH. It even slipped with the gold springs. Can anyone tell me if I can just clean the current EBC HD clutch and start over with semi-synthetic oil? Do I need to replace it? Should I go back to the stocker and put in green springs? This has been a minor bummer for almost three years now.
