I have a 2008 crf250r and it does not like starting at all. The only way i can get it to start is to catch it in gear going down a hill. We already shimmed the valves and sprayed carburator cleaner in the bike, but to no solution. We think it is an electrical problem and we are testing the circuits out on a meter. All of the readings we are getting are so low compared to what the manual wants them to be. If anyone knows what might be wrong, help would be much appreciated.
