Sick Bike Parts has some high quality wide Bottom Bracket CartridgesI know I did see one of the Bike Parts Places had off set Pedal Cranks for added Engine Clearance . Were can I buy them and is it also better to run shorter ones .
And this is where the throttle comes in handy......who needs to peddel?Tango,
Give the link to the source for those for others. Thanks. I've used several of the first one shown on wide four strokes. On two of them I still needed to bend the arms even more using the arm-strong method Venice suggested. One advantage of the first one is if you need to lower a four stroke as much as possible to fit a big engine into a tight frame you can change the sprocket to one with 36 teeth, as found on some kiddie bikes for free. The bad part is that the crank arm is keyed into a hexagonal shape so most other sprockets won't fit the crank. So, you have to file out the round hole into a hexagon to fit. Not a big deal, but takes a little time.
I don't know that the three piece can use a smaller sprocket, but the advantage with it over the first one is that it is even wider. I don't have the measurements for you offhand. As I recall they're the same price and good quality. Using short arms makes pedaling harder and if the pedals are under the engine that can make pedaling difficult, too.

Ever find the link as it is my missin link (wink).My source is a different one and they sell both the extra wide one piece and extra wide three piece for cruiser bottom brackets. Both sell for thirty bucks not counting shipping. I'll try to find the link and post it later today.
