I read somewhere that compression on these NSR250R's is about 128/cylinder, and that a top end job should be done if they're down to 100 or below with a difference of 10 or more between the two. Does this sound about right?

I've got an MC16 with 100 in one cylinder and 90 in the other

Her Symptoms:
-Hard to start when cold, 20-40 kicks! (Compression issue?)
-Hesitant between 6-7k rpm, not smooth troughout rpm range, solid after 8500ish (Carb issue?)
-Smokes like a veteran! (Comp issue?)
-On cylinder is slower to fire up than the other (Comp issue!)

So, pretty sure i have all the indicating signs haha. Thought I'd run it by you gents before I give Tyga some added income and start breaking her into pieces,

Cheers
