engine is std i think ! i got it from gecko and i dont think dan knew if it was a mc21 or a 28
it just had no power when i rode it ,really flat , and i started to run very bad and only just got me home
it wouldnt rev at all , just so numb when you try'd to rev it !
it just got worse and worse im a bit pissed off with it at the minute
i might end up just rebuild the other motor and put that back in ! but after £1100 i wouldnt mind using this one lol
ive got most of the 250's or had them in the past and never had one running like this ,not even when one had siezed and managed to limp home !
