Just picked up a 86' XR600R a few days ago. The bike was sitting for 2 years. I cleaned out the carb and jets. Put a new plug in it and some 93 octane gas. The bike would only fire maybe twice out of an hour of kicking it over. I decided to push start it instead. It started right up on the first push. The bike runs good and idels great. I did notice that when you snap the throttle quick it kinda bogs. I checked the spark, and it looks kinda weak. Is there anything that I could do to get it started easier? mY buddies 85' 650R starts up on the 1st kick . Thanks in advance!
