MountainMan, don't think "White Zone". This is pretty germane to buying these kits. Can't really go in "Vendor Review", since that is not for a discussion.
Gasbikes.net or whatever they call themselves, need to be exposed for what they are just a storefront with nothing behind it.
If the price is right and you are willing, buy from them or anyone else.
I would love to find a vendor that sell engine kits and all the parts needed for their "brand" of engine.
What is nice is the non engine kit vendors that sell the improvements that really make these things fun. I really hope that guy comes out with a gas tank line, that will be a nice addition.
