L, Tritons often run balance factors up to 80% and spin to 8,000 RPM. Your motor has a heavier crankshaft and if it is balanced to 72% is probably swinging a bigger counterbalance. When my Seeley 850 is idling it actually rocks backwards and forwards due to that balance factor. As soon as I start to ride it the roughness disappears . You obviously could not sell a production road bike which did that, to commuters who had the choice of buying a Honda CB 750. However the problem is minor and certainly not intolerable. If I was buying a British big twin in the 70s, I would have expected it to be rough low down in the rev range. The trouble was that the market had changed and customer expectations had become based on what the Japanese could supply. My feeling is that Ken's 2007 racer is brilliant. It is worth bearing in mind that one definition of the word 'quality' is - 'fit for purpose with obvious attention to detail'. Ken's bike fits that perfectly. The 'purpose' is road racing in a particular class, 'attention to detail' - it is perfect. So I suggest you have to think about your intended purpose for your bike, compromise bikes often suit neither purpose very well.

[QUOTE="acotrel, post: 227925, member: 4295"] L, Tritons often run balance factors up to 80% and spin to 8,000 RPM. Your motor has a heavier crankshaft and if it is balanced to 72% is probably swinging a bigger counterbalance. When my Seeley 850 is idling it actually rocks backwards and forwards due to that balance factor. As soon as I start to ride it the roughness disappears .
