I have a 2008/2009 TTR 125 that won't start. It was a family bike purchased brand new from Yamaha dealer that has been cold blooded since day 1. This bike has been used and abused. I hate to admit it but for a lot of this bike's life, it was only being started using starting fluid spray. At this point it has been sitting in the garage not being used and it is very very rare that someone is able to get it started. It feels like it has no compression whatsoever when kicked. I have cleaned the carb but it didn't seem to make much of a difference. Is there a way to test the compression and find out what is going on?
