Well it's about time! You could borrow my project 500 AVL head, it's still sitting on the bench after being drilled and tapped for an iron engine decompressor. Bullet Whisperer has even fitted some comp valve springs, only trouble is, it's on the wrong side of the Pond for you guys! Plus it has already been ported, possibly rather differently to what you might have been planning. The head is a lovely design, and with all BW's work on cam selection and compression hikes already giving good results with a stock head casting, the thought of a Mandello-quality AVL head is very tempting. The quality of the stock port work, particularly where the valve seats are fitted, will NOT make your day...I'd also be intrigued to know what cams and carb you're planning to use if it's not a trade secret!Regards,Adrian
Tom, let me think it over. At 64 years of age and almost 50 years of tinkering with bikes, I've become a pretty good wrench and could certainly participate in final tuning. All that said, cost would be a factor, and the timing couldn't be worse. Spring is poppin' here in Southeast Louisiana and it would be tough to rip the heart out of the Bullet and miss the best part of the riding season! Bob
Tom,more food for thought: some of the more recent designs of Dell'Orto motorcycle carbs have oval bores, one of these could fit well with a 500 AVL inlet port.Regards,A.
