Recently fitted a new engine, tis running quite nicely, bar a little whizz/ rattle fromthe front end, it's prob the cam chain tentioner...but thats something to do another day.

I've noticed two main things that concern me.

1) In 2nd gear around 4K - 5.5K Rpm we've got no power, or the power we have in terribly lumpy, to the point where the bike is actually rocking forwards and backwards.

2) When we finally get up a bit of speed, say to the 100Mph mark, and above it's rather difficult to maintain a steady constant speed, now im aware of the engine braking on the SV's but surly it shouldnt be that strong around the 100mph mark, the best description i can give is that it feel like i have to constantly apply more throttle to maintain a constant speed.

I've a K n N filter in there, with standard jets, and a CCC Can the carbs were balanced recently. but again she's never been rejetted.
