Hi everyone. I am fitting a pair of these to my 76c 650 as my pipes have rotted out. Wondered if anyone has had experience of jetting up for them. I am using std air filters, std headers, bs38s and currently std jets 122.5 main, 25 pilot and 4mi needle. A good starting point would be great i know every bike is different and there are other aspects to factor in. Naturally these will be more free flowing pipes.
