    Just picked this up for a song on CL. ($100) I've had a new Grubee Skyhawk 66cc kit sitting for over a month waiting to find the right bike. Wanted to go with something with a front suspension to sooth out that ride a bit. (2 past back surgeries). Also needed something big, as I'm 6'3" and 220lbs. And boy the XL frame on this is BIG!
    I'm wondering if anyone has experience with this expansion chamber from Bicycle Motor Works? Pretty cheap at $27.99

    I used the muffler from the Grubee kit on another bike and was debating to try something other than a stock exhaust on this build.

    I am in the process of building the exact same bike. I also purchased mine used but I paid 150 for it. I too like the larger wheels and bigger frame and I am 5'11". I also am putting a Grubee Skyhawk on it but I have purchased a shift kit from sick bike parts and I'm going to give it a go. Good luck on your build. Post some pics when it's done.

    Should be a nice strong frame with plenty of room to mount an engine.

    Plenty of room for mounting. A little Dremel work on the front mount, fits perfectly. Back went right on nicely as it was..flg.

    Hi Burrus, I just got done with my Crossroads build yesterday. I was stuck for a bit on the exhaust. I have a stock exhaust that did not fit, I have one of those flexible hose expansions with a muffler on the tip and it would not clear the front tube either. I ended up doing some wild configuration on a banana pipe and although it's not pretty I really like how it operates. The exhaust gets thrown away from the bike and right under the crank but not shooting towards the crank.
    I believe that because of the shift kit or the angle of the frame and that big front tube there is just no easy exhaust for this bike. I was thinking of ordering one of those MZ Miami pipes because they look like they have a sharp bend off to the left and could possibly clear but I wanted to use some of what I already had available.
    The bike turned into my favorite build instantly. It has an extremely confortable riding position and the suspension seatpost and suspension front forks are badass.
    It was my first time doing a shift kit so it probably took me 7 hours to build plus another couple hours messing around with an exhaust.
    I must say though that having the shift ability on a bike is the icing on the cake. The gearing range is perfect. I can't wait to get this engine broke in and really find out what It can do.

    I am not trying to hijack this thread, Burrus himself requested I post some pics of my build once completed since we started almost at the same time on the same frames.
