Hey there, I have a 2007 WR 250F that has the Thumper Racing 290cc kit in it! Bike runs AMAZING, as long as the battery stays charged. I have put my 2nd battery in the bike, and it has already died, and it wont hold a charge. Same as the original one that came with the bike! So, I would imagine there is a shirt in there somewhere. Well, I honestly don\´t have the slightest idea of where to look. So, I was hoping someone here may have some suggestions! I can post more of any kind of info that you may need. And yes, I have pulled the grey wire, so it is timed like a yz. I have also disconnected the Headlight and removed the digital Odo (ICO BABY!) So, let me know what ya got! Please email me any questions or suggestions!
