After installing the crash bobbins i started hearing the most annoying 'ringing' sound from the engine always at 5000 rpm in any gear. I removed the crash bobbin, sound gone! Eventually i put electrical tape all along the central bar, reinstalled the xrash bobbin, and hey Bob's my uncle, works great now 🙂.
Evotech make great products, please start making front crash bars so i can buy them from you 😜
