Hi!

Yesterday I wrote that I would like to change the location of the battery. It is placed opposit from exhausts muffler. As you can see in this picture under the back plastics.
If you really need an explanation why do I want to do it, I'll do.

I removed plastics and the seat. I think that the place of air filter box could be good for the battery. But if I change the place of battery, I need to remove the air filter box and attach good and small air filter directly to carb.
The place will be enough and practically it is easy to do.
But may I do this modification? I think, will the engine work properly without any problems? I know that I'll have to regulate the carb.
Some pictures:

If the modification is correct, could you please advise any air filters which could be the best for this mod? K&N or twin air or other and what model?
