Chipewa Posted January 15 Hey Thumpers, 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? Thanks, Chip Share this post Link to post Share on other sites
phabib Posted January 15 Are you sure the kick starter is working and turning the engine over? Verify that first, then to check compression remove the spark plug, thread in a compression gauge, kick it over and read the compression. 1 Share this post Link to post Share on other sites

I was just curious if this may be the issue because the kick lever has no tension what so ever, as it does not even begin to turn the engine over. Pretty much the only way to start it is to spray starting fluid in air filter, close lid, get a running start, cross your fingers and bum start it. If the kick was not turning engine over, what would that possibly mean? Chip Share this post Link to post Share on other sites
Cody Ludlum Posted January 15 There is a gear inside that when you kick it makes the motor turn over. If kick started is very soft but you put it in gear can't push it that is first thing I would look into Share this post Link to post Share on other sites

Probably going to end up pulling it apart. Share this post Link to post Share on other sites
phabib Posted January 16 I vote for a broken kick. The fact you can bump start it means you have compression, and everything else you need to make the engine run. Share this post Link to post Share on other sites
