125M sprockets

[Sxb3646]

Hello. I recently purchased a 1985 125M and I'm working on making it my own. I would like to gear it down a little as I find the low range gears to be a little fast and I am not concerned with the high range being particularly fast, in fact I rather it be slower in high range and not strain the motor or clutch to take off. So what would y'all recommend me change my sprockets to? I think the factory set up on this bike is 14 tooth front and 49 tooth rear. And where can I find aftermarket sprockets in different sizes to fit my trike?
Thanks.

If you really want a recommendation, I personally would recommend you leave it alone.

If you are dead set on changing it, then I have no recommendations.
