I was considering getting a HPd pipe and maybe even a clutch kit to go along for my 1998 Scrambler 500 4x4. Since I pretty much have no experience with modding out quads I have some questions. When putting on a pipe and/or clutch kit, is there any more maintanace than stock? Is my quad prone to more problems? Is there any decrease in resale value for a modded quad? I know these aren't major mods, but I was just curious as to what I would be getting into.

Thanks
