These speedo's with stock tires can be off by 15-20mph
Very inaccurate guages, tires with different rolling circumferences, different sprocket ratio combinations or a combination of all 3 would do the trick.But why the huge difference between similar bike?
Up shift?
I don't think any of our bikes will reach 11,800 rpm (missed-shifts excluded).My bike wont reach 11800rpm. It bogs down after 8500rpm. Still trying to figure it out. Any ideas?
With luck, everything will check out fine and you will be reduced to becoming a carb cleaning expert like most of the members on the Forum. .
Unless you break some fragile little part in the process it will cost you nothing except time, frustration and likely a bit of your sanity. Good luck.
from previous marked website. Personnelly, I couldnt get mine over 85 mph.A top speed of 105mph can be achieved while acceleration over a standing start quarter mile takes a very creditable I4.o.secs. There are single disc brakes at either end to stop the bike which are mounted on attractive alloy wheels which, in turn, help take away some of the bulkiness of the bike's looks.
