Well we had our rain today, the heaviest part went south east of me, and inspite of the rain I tore the old Red Bat BGF engine down, I did some port work, really hogged out the transfers and cleaned up the intake and exhaust port real nice, I also installed the Titanium wrist pin and Aluminum Bushing I got from Juicemotoparts.com , made a new base gasket and put it all back together and then road the bike for a 12.8 mile road trip, vibes were noticeably reduced but since the crank in this engine is so untrue I still only have a. Omfortable cruise speed of 30-31mph which is up from what was a 27-28mph comfortable cruise speed, thenport work I did made this little engine come alive in the low and midrange, it pulls way harder then before and maintains it speed up the area hills really nice now, im gonna put a better exhaust on this bike which will quieten it down and hopefully keep the power where and how it is up to the 30mph comfort zone, Im thinking I will go back to a 26"rear wheel and a 36T instead of the current 24" wheel with a 32T sprocket.
So qnyway rain and all I still managed to get some tinkering done and time will tell if the Titanium pin and Aluminum bushing will hold up, im not sure what grade of alumuinum they made that bushing out of but that thing is hard, a small fine file wouldn't hardly even scratch it, not real confident in it but so far not a click in the engine, so after some miles we'll see how it ends up....
