I just bought a (barely) used TT-R50E for my kids. The person I bought it from let the battery die, which I found out while I was out looking for a battery charger and had the battery tested I am having a very hard time finding a charger that works for this battery. I don't want to kill the new battery that I have ordered and Yamaha does not seem to recommend one. My local shop also seemed to be clueless. The parts guy tried to sell me a charger that the service guy told me would ruin the battery (?). Can anyone recommend a charger that works for this battery? Although we have two other TT-Rs, a 90 and a 125, and I really like Yamaha products, I am frustrated that I'm going to have to spend so much time maintaining the battery. And $400 for a kick start kit is robbery, in my opinion. Yamaha must be counting on people buying this kit, maybe that was the only way they could get the price so low. Otherwise, it is a great bike. Thanks.
