a basic lightweight 65, nothing wrong with that at the price. not much negative about BGF here, except my own universal beef about honest engine sizing.
personalize your kit now...get any upgrades you want prior
to the build. you're hip to the clutch-lever, but i notice the pic shows the plain-jane idler/tensioner, so either make a better one (some great ideas here about that) or grab a bearing'd one somewhere. and, just in case, i'm taking an educated guess that those cables will only be barely long enough for the most average size frame and handlebars.
EDIT for reference: this topic, so far, is another fine example of "kit" components being every bit as important as the engine itself when making the final choice. just do the above math so far then go looking around with the new total-cost as your "cap"...see how the equation changes and different combos of engine/kit become available?
and since i'm here, i might as well say it:
read read read the heck
outta the frame-mount and general discussion areas, and get all over the parts and accessories forum, too. i can't keep up with everything going on, so maybe i missed your bicycle info? sorry if so. is it ready?
please keep us posted on how it's going...as the thread grows and the build progresses, you may need to do some editing or whatever. just PM me with the details and we'll rock it out
