this battery is sooo weak ive had to replace it 4 times with only 100 miles on the bike i dont know if there is something else wrond with it that is draining the battery or that tey are built to run completely off the battery in te cooler weather i cant get it to stay running even with the batery immediately taken off the maintainer it fires but wont accept anything else like the batttery cant handle it something is draining electric or the brain bc htey dont ave alternators or they are built to run completely off this tiny battery and with that said the restrictor being removed probably does not help
