Damn!!! I think I'm doing to down shifting ALL wrong. I certainly don't sound like that when I'm down shifiting. Back to basics I guess. Triggerhappy, could you give a quick write up on how you're down shifting?
In it's basic form it is simply called 'blipping'.
As you need to slow the bike and get in a lower gear, you pull in the clutch and bring the engine up to the RPM's that will better mesh with the lower gear with a quick 'blip' of the throttle. this happens very, very quickly.
For example, if I am in 3rd gear running around 10k rpm and want to go to 2nd if a just down shifted I would either have to 'slip' the clutch(let it out slowly) dump the clutch and hope my rear doesn't lock up, or as i pull in the clutch I will quickly blip the throttle up to 11-12k and then let it out. This better matches the engine RPM in a shift to the gear you are shifting to. 3 to 2 (or 4 to 3, etc.)
It is something that does take practice, but when you get it right it is the only way to go when downshifting at aggressive rpm's
There are probably some tutorials out there that will explain it better than I can. Just search 'blipping the throttle when down shifting'
Hope this is of some help!
