I've seen some pics and it looks in decent shape, and the guys says everything works well, BUT when the trike is put into forward gears it grinds. I've read that this could be a major problem, and i've also read that it can be easily fixed.

If anyone has any advice on this particular problem and any potential remedies and their costs it would be greatly appreciated. I really don't want to drive a couple hundred k's and drop cash i don't really have on a trike that may be useless without a costly repair.

Thanks!
