PGO Bigmax tuning Parts List *tribute to PGO owners*

Ok finaly i got some free time so i've decided to post up a few more stuff, i'm getting the Port timings guide ready too but i need to revise it since i don't want to hurt anybody's engines with typos off my part.

in the mean time i would like to contribute to those who happen to have a PGO BigMAX 50 scooter, i know this scooter is a minarelli legend model engine, but when it comes to finding parts for it any one will be stumped. Not only does this bike have an ackward custom cranckshaft, it also has mixed Honda/Yamaha parts inside. I own this bike and it's my base machine for all of my tuning needs.
Below i have listed all the parts that will fit the bike nicely for those of you wanting to know before you go buying stuff you'll have no use for later on .

The crankshaft
--------------
the stock is a beefy full circle one stronger than most other bikes and can survive circa 12K~12.7K rpms (personaly tested and approved), if you don't have a secondary replacement at hand and would like to improve the failsafeness of this crank, use these bearrings with it. if you would like to switch to a full mass version, BGM is the only make who makes the PGO race crankshafts
