  1. thanks for the reply would it be best to put some rad flush through the system or is there an easier way to clear it out
  2. It sounds like the woodruff key has snapped take the flywheel off 'that brake drum looking thing' using a flywheel extractor and you will see a groove cut out where the crank shaft slots through this is a locator for the woodruff key then look on the crank shaft that you've pulled the flywheel off and you should find whats left of the woodruff key. should be able to find a new one on ebay only like £5 for new one
  3. Hi I have just recently bought a k reg tdr 125 and it keeps nearly overheating I switch it off just before it goes into the red after about 5 mins of riding, ive fitted all new hoses as one was split and iv already checked the thermostat is opening so I cant work out why its getting so hot so quick, I have noticed that when I start the bike all the coolant is forced back up the rad and out through the expansion bottles overflow pipe at the back of the bike. any suggestions on what is causing this problem would be much appreciated thanks.
