I purchased a new 825i 2 months ago and noticed that the clutch did not engage until the motor hit nearly 2700 rpm and would be about 3000 rpm going 3 mph. The dealer said it was a high revving engine and that was all they would say. But I was not satisfied with that answer and started researching. The forum here had some other people talking about the weights and springs in the clutch and having to contact the clutch manufacturer about a new spring and possibly dropping the rpm by 500. This did not sound like much of a solution.
After a month, I went back to the dealer and test drove a diesel model and its clutch engaged at around 1400 rpm. So we looked at the clutch parts for the 825i and the diesel and found them to almost identical. the spring was different the weights were heavier. After ordering the new spring and weights for the diesel clutch to swap out with the original parts we hit a snag. There is a difference in the clutch housing where the weights fit. So we had to order the complete diesel clutch. Then had the Dealer install the new clutch, no other modifications needed.
Now my gator engages at around 1400 rpm and goes about 12 mph at 3000 rpm, and when put your foot down on the gas the engine comes to life and you better hold on at 40 mph you are at about 5000 rpm. The fuel consumption was cut by half due to the lower rpm's and you still have all the power you need. This modification was took less than a day and made great and very useful machine.
