Barely.... I think you're missing the point of having a "custom bicycle building contest"! If heavily modded frames (& tanks) leaves too few contestants? How many people do you really think we have here with the skills to truely modify a engine???
We're gonna end up with a contest where everyone just bolts on a bunch of Jims parts, a SBP pipe & a CNS carb onto a totally stock Wally World bike.... Thats not much of a contest... I can look at several pages of those bikes right now in the 'pics & vids' pages!
If we're gonna have a contest of "bike building skills", Lets have a real contest of "bike building skills"!
