Yea, I'm a believe in JBM products. I used to have to replace sockets on my CGS Hawk 503 every couple of years. They would always show signs of dry rot within a short time. I went the JBM route and never changed them again. I just recently ordered new JBM carb sockets for my 912. I haven't changed them yet. Annual time is coming up in December and almost 5 years since I completed my model 4 got me to thinking about rubber replacement. I'm inclined to agree that total rubber replacement is unnecessary at 5 years. My main issue is the oil and coolant hoses. I'd like to find a source of good quality hoses but the sizes are hard to find. They are sized in mm and don't cross reference closely to standard sizes. Thanks for all the good advise.
