Hi all. I recently purchased a 87 XL600R, after not having ridden for nearly 15 years. I know the procedure to start this beast, and have had no problems until recently. Normally when the bike is cold, I give it full choke, no throttle, and it usually fires on the first or second kick. When it is hot, no choke, no throttle, and same thing. Lately, I just can't seem to get the bike to start when it is cold. By cold, I mean later in the day. Early morning cold, it still starts immediately. Later in the after noon, after getting off work, and the bike has sat for several hours, I kick & kick until the sweat pours. After 10 - 15 minutes of trying different choke positions and throttle, it finally fires.
Once it is running, everything is fine until the same time the next day. The carbs were rebuilt a few months ago, its getting fuel and spark. Could this be a choke issue with the warm summer days?
Sorry for the longwinded question. Any help would be appreciated.
