I have a 1995 xr100r that won't idle right and has a top end miss. It is bored and jetted with all new carb and filter. I set the valves and cleaned the carb 5 times but still won't idle and has a miss and will die on ocation with a high idle. Any help would be greatly appreciated! It was running fine after the bore job and it sat for 14 days and cannot get it back right. Tried adjusting the carb and all and nothing changes
