Shake down of the back from the dead 650D is underway. Still not sure about the side panels not fitting with CVK34s. Keeping an eye out for decent used ones. But, I'm thinking that if I remove the gaskets between the inlet rubbers and the head, I can seal that joint with some good quality joint sealant. I like Loctite 574. There might just be enough room to fit the side panels unmodified as the carburettors with be mounted a bit closer to the cylinder head. Just something I'm considering for now. That's not happening imminently.
First couple of rides on the bike are very encouraging from a performance perspective. With the 2 into 1 Delkevic exhaust system fitted and the CVK34 carburettors, I think this is probably a unique situation. I'm mindful of not burning a hole in the pistons through a too lean mixture.
Yesterday's run was 5 miles. Combination of stop start, 50 - 60mph steady throttle and up and down gears. Then back home to look at plugs.
Very impressed with performance. The carburettors are clearly a decent option to replace the old Mikuni CV carbs.
Set up is 38 pilot jet, 2 turns on the mixture screws, JJJ needles in middle slot and 138 main jet. Foam filters.
Starting, throttle response, steady part throttle operation, closed thottle over run all pretty darn good. Plugs came out coffee coloured so I'm not running dangerously lean. I'll extend the distances I'm running over the next week or two, but it's an encouraging start. Plugs aren't this dark in daylight.
