Yes we got the carbs perfect , very easy to tune but at 125 hp there past there best so we went to 45mm Weber's the 600 carbs were very smooth but rejected lots of fuel at 5000+ rpm , the length of the manifold was to short for the job , and as we are after 150+hp we needed more air and Les deemed the head and carbs needed more work so i have ported the head again and had the head stud do the guides and seats , and i fitted new springs so we could rev it to 8k and Alax has got new 45 carbs and manifold
