i have just finished reassembling my wr426 after powdercoating the frame and a full motard conversion. i installed the yz450 decomp cam while the motor was out, all valve clearances were slightly out of spec so i replaced them all with CRF450 shims(.025 increments).also changed the fuel screw to an easily adjusted version. now it wont fire?? previously it started first kick every time. i checked the plug before reassembly and the gap was fine,colour was fine. checked the coil with a multimeter, all good. havnt tried bump starting because i have a rekluse so i cant. one thing i did notice is that there was a lot of fuel being dumped from the lower carb tube??? any advice??
