400ex battery in YFZ

[cliq20]

Same old battery issues. I'm going to try to fit a 400ex battery in mine.

Anyone put one in theirs and how does it work? Did anyone have trouble with being able to get it to work? Is there anything else I should change? Does the Trail tech rectifier make a big difference? Thanks a lot in advance.

A friend of mine did it he cut the plastic so it would fit it works good and the battery is a lot cheaper they sell them at wal mart its like $50
