Advice please.
I have a R100RS and it seems that there is an internal leak between the drive shaft and the final drive.
I drain and refill the drive shaft with 150ml fluid. Check the final drive and make sure the fluid level if correct.
When draining the drive shaft fluid about a month later only +-50 ml are left. There is some fluid moisture around the breather of the final drive and when checking the level in the final drive, it is overfull.
1. where is the seal between the two? The Haynes manual is not clear on this.
2. is the replacement of the seal a job that can be done easily at home?
