MLM BK100 Installed

Threw the new pipe on the ped and cranked it up...just had to hear it running.  SWEET!!!  It sounds great....maybe it's just my excitement, but it sounds like it revs up with more gusto than the old Boss pipe...proof will come when I get some dry roads and take it out for a spin.  Can't wait!!


Now it's time to tear down the whole machine...need to get a look at the clutches (haven't cracked it open since I bought it)...want to look at what kind of porting can be done (or has been done), and get this tip top for next season.

The new patch is on the seat too...I'm sure the competition can read...but will they follow directions?

Winter time = build time

We are all working away on our mopeds...parts are trickling in, and the occasional email goes around about what we are up to.  Even in the off season, it seems we are consumed with these little machines...who would have thought moped racing would be so much fun?

After a month of issues with 1977Mopeds, the new pipe for my ride has finally arrived...a sweet MLM BK100 with side bleed exhaust.  It's a huge difference in design from the Boss pipe that came fitted to my machine.

The 2013 rules for NEMA are coming together...Victor (the events creator) has been circulating emails around the new rules...I imagine they will be sorted out in the next week or two.  Based on what I'm seeing, it looks like my machine will have too many mods for the JR class, so I'm expecting to run in the PRO class next season.  I have my eye open for a stock Tomos A35 motor/transmission, and if I can get it dirt cheap, I may do engine swaps between classes...but not sure about that yet...honestly, I'll likely just stick to PRO class and focus my attention there.

Work is still underway on my massive front brake...need to talk to my buddy Art about fabricating a mounting bracket for the caliper.

Tony is still hunting down his machine for next season, and Turtle has many parts in (or coming), so big changes to the team bikes are coming...top secret stuff there.  :)

I'm still working on the on-board computer.  Initially it will be for data acquisition only, providing CHT, EGT, RPM, speed, throttle position, and lat/long (GPS position data).  The race critical data will be displayed to the rider, while all data will be sent back to a laptop wirelessly in real time for logging/mapping/post processing.  This should help me keep tabs on how the bike is running, what effects tuning changes are having, and hopefully I'll gain some understanding into how my riding affects my lap-times.
