I just bought this 2003 crf450r Honda and find it very difficult to start,guy I bought it from says there is a certain techneake to starting it,i have tried that and find it still hard to start,seems like cold starts up easier,if I stall it out its a bear to restart and that´s well before it is warmed up good,at that point the hot start lever should not have to be used due to the engine is not that warm,i had many motocross bikes I used to race in my younger years that were never a problem to start but by the time I get it started im to tired to ride it,is this acommon problem with this bike?any help out there sure would be appreciated?
