I have a 2006 Sr50 R Factory thats fully derestricted with a stage 6 pro racing exhaust, it accelerates fine to 30mph then seems to just stay there and accelerate very very slowly from 30mph onwards

Some exhaust have two restrictions. One in the front and one in the rear.
Your roller set up could be wrong too.

How fast does your bike eventually get to say on the flat. If you are getting over 40 then physically look at your variator shaft and make sure the spacer is gone. Then we can look further. There is a sticky on how to derestrict your bike - its a good one.

Whoops - typing too fast I meant to say NOT getting over 40

Is your ECU 'done' ?

I just had a quick go, i had 30-35 on a flat but about 41 downhill, im going to see my local dealer tomorrow and ask them to have a chack over for me, hopefully its only minor and not too expensive to sort out

the problem seems to be getting better everytime i ride it, iv just been out and i seems t be increasing a bit every now and again, i think i need my rollers changed anyway so hopefully it will be fine by the end of the week
