I have an '83 Yamaha YT175K 3-wheeler and I want to do some mods on it...everything is stock right now.

Does anyone know of a power kit that would work on it? I looked around but I could only find kits available for newer atvs. If I can't find a kit, I'll just buy some bigger jets and a better air filter.

Carb - my current main jet is #170. How big could I go before damaging anything?

Exhaust - any suggestions?

 

well they really dont make that many modds for them but cobra makes an exhuast for them and pro flow,uni,moose and a few others make air filters for them. but as for jets i dont know where you would get them. i have the tri motot 125 and i have looked high and low for performance up grades for it and there just arent many around
