  1. I'll definitely have to check that out. I've got a new OEM coil on the way so hopefully I can get it going before too long. Thank you for your input.
  2. Hi RockerYZWR, Would you by any chance have an extra ignition coil? If you have one I may be interested in it along with your CDI. Thanks, Matthew
  3. Hey guys, I'm new here to thumper talk, but not new to dirtbikes. I recently purchased a used, 2009 yz250. The bike has been running great until the other day when it randomly started bogging under any load. I have fully cleaned the carburetor, making sure the float height was correct and freely moving. I checked the resistance on all ignition components and everything is in spec except for the coil. The service manual calls out 0.2-0.3 ohms at the connector. Mine is reading 0.4 ohms. Will this be a big enough difference to warrant a bad bog under load? It's bad enough to where that I can't even ride the bike. It revs great and idles fine while on the stand though. Any help would be appreciated guys, thank you!
