The best thing I can think of to describe what the RC feels like with the 15/41's is like my old 350 2 stroke. I am literally riding it now the same way as I used to ride the RZ.
I am now extremely
careful coming out of corners and the same with acceleration from stand still. With the 15/41 I only open the bike up to full throttle from 3rd gear, anything below that I need to request take off clearance from the local airport
It's insane ...but great fun though
To give a little more detail ...the power comes on in a rush if you open the throttle hard and fast, and if in first, it is an instant 90deg vertical wheelie :-).
If I gradually open up (reasonably fast though) to full in 2nd from about 4000 rpm, the front starts hopping immediately and then starts 'climbing' when I get up above 6000. I have not given it too much of a chance to do that, so exactly how far it will come up I cannot say. I also have not tried "snapping" the throttle open in 2nd, but I can tell you it will wheelie instantly if I do
Bearing in mind that I am extreme altitude and running a stock RC, I can guarantee that for those of you in lower lying areas with any mods will have the same problem in 2nd and possibly in 3rd that I have in first up here.
What I am going to try is putting a 16 tooth front sprocket with the 41 rear. This will be better than standard and nowhere near as radical as what I have now.
Soon as I can get the sprocket and try it out, I'll post the results
