Warning: Poor Service from 6sigmajetkit
I had a very negative experience with 6sigmajetkit. Despite providing full details (VIN, model, year) for a motorcycle part order, they sent the wrong items. When I tried to resolve this, eBay informed me that return shipping would cost half the purchase price. The store, 6sigmajetkit, was unhelpful and refused to assist, hiding behind policies instead of correcting their mistake. I advise against using this store based on my experience.

WOW! Let's unpack this one. 1. No details were given, none zip zero. We asked where he sent them to, no answer was given 2. We sent exactly what was ordered, A jet kit for a VT750 Aero Single Carb. As it turns out he has a much later model and different VT750 that is Fuel Injected, meaning it has no carburetor. 3. Item was shipped using Ebay's International Shipping Program. So, we can't do anything for return shipping, it is 100% Ebay's return policies that he is unhappy with due to HIS mistake
