First off let me say i am not the most mechanically inclined guy..but i successfully changed the oil, and oil filter with no problem on my Breva 750. But for the life of me i cannot find where the air filter goes or how to check the other fluids. I did buy what is supposed to be a Breva maintenance book off the internet but i still can't find the pictures and/or instructions. I have gone through this manual a number of times and unless i am totally missing the schematics ..... Would appreciate it if anyone can post either a photo or direct me to an online link...thanks!
