Just picked up a 1987 TW200 and it has a big issue with loss of power. When i start up it might take a minute to 5 minutes but it will begin to idle oddly. I can make it happen if i open the throttle past 1/2 to 3/4 open. it will sputter and will not respond to the throttle. It's more like a high idle that keeps getting grounded out. the head light will go from bright to dim and back again as well. I have cleaned the carb 2 times now, inspected the pilot and main jets, cleaned every hole through out it. i don't think it would be an electrical issue since it is so intermittent but who knows at this point. When it losses power, it really goes dead... it's quicker to walk it around than engage the clutch. Sometimes it will regain power if i let it sit it seems or if i push through it on WOT for 15 mins. Another issue that may and or not be related (goes back to electrical) is the fact that when i turn the key to on the only lights that turn on are the tail light and neutral light (the headlight and speedo light don't come on till i start the bike, which is odd since it's a new battery) If any one has any ideas... i'm all ears. PLEASE PLEASE PLEASE help me out! Thanks!
