Hi there I've had my 1994 import sr250 for about 2 weeks and changed the oil last night. When I was riding her home twice she lost power and felt like she was coasting! Is this anything to do with oil change? Thanks guys :-)

did you bleed the air out of the oil galleries ?? one bleed placed on top of the oil filter housing and the other on the head on the right hand side of the engine

No I didn't bleed it. I used 10w 40 fully synthetic oil also.

is the clutch slipping? check the oil level and that you used proper bike specific oil, as in not car oil
