Thanks for the replies!
Just pulled the carbs off, and she's got 115 MJ's and 35 SJ's. PJ is blocked off with a screw and sealant. I think i might solder it. It was leaking round the float bowl seal, so I'll need new float boal seals. Not sure if it could be float height as well? 13mm is stock for NSR and I found this one to be: 11.75mm and the other 12mm. I know its been played with as theres marks and looks as tho its been bent a few times.
I've never rebuilt this engine eh, but as far as my method for checking compression: I just kept kicking it over and over and over, and she was warm. Was my method flawed?
The Air filter looks fine, i had cleaned it before and sprayed it down with air filter oil again. Is the MC16 filter the same for all Nsr250r's?
