Default SBP 4 Stroke Prototype

Just thought I would give all the members here a sneak peak at the new 4 Stroke unit. Time to start testing but of course our lovely weather up here in Washington is raining, as usual.

I Like It I Was Thinking About Going To 4 Stroke,on My Next Project. Now You Need To Get A Tuned Pipe For It.that Would Be Sweet.how Much Did It Run You, If You Don't Mind Me Asking?

Well if someone would send me one I might.

D4of4,
This is our prototype. We will be testing it over the next month or so and then get it on the market. BTW tuned pipes don't do any good on a 4 stroke.

Sweet! If that was my bike I would get that throttle on my left so that I can pull the rope with my right. Of course you can still run it easier on the right and on the left it throttles backwards but on my bike it's way cool and a bit anti theft cause crooks be a bit confused.
Anyway,forget what I just typed. That went together quite well.
