Default Starting the mod process

Well it's that time of year where the bike go's in storage in my case my basement. Well it's time to start modding this beotch internally. Now I DO NOT want to hear any B.S about why would you mod a 250 yada yada. A: This is my bike I can do whatever I want. B: it's my money I can spend it as I want, C: I do this stuff for a living so it's pretty much free. Anyways I have 2 goals here. 1 to make enough power to where I can change gearing so the bike is not screaming down the highway and not a slug in town. And 2 have enough compression to justify running Premium fuel as we have no ethenol in Premium up here in Northern WI. What am I going to do? I already had it dyno tuned last year so I have a base line. Going to deck the head to bump up compression, Run the head on a flow bench followed by some porting, advance the cam timing to compensate for the decked head, and also adding a different fuel controller where I can adjust ignition timing. And of course get it tuned and hopefully see some decent results. Here's the first pic of tonites start. I will be adding pics as I get time to work on my own bike. Any input is welcome.






Cleaned up the valves


And honed the cylinder. Look at that nice cross hatch

Surely a cam change is near top of the list. I'dd say the standard is pretty low lift, short duration to bump up the fuel economy.

Allright guys, Had some time today to get it torn down as far as I need it to be. Now I need to pull the valves, clean everything up, Deck the head and press the cams out of the gears and change the cam timing.Also need to do the porting. Here's a few pics.







Honda even uses a moly coating on the OEM piston

Looks like you been busy! If it all works and you get good numbers you might get a 250 motor shipped to your house so you can do it again :P

Ohh and the Anthrax, that would be okay as if I know my mom like I know my Mom she will snoop in the box just to see whats inside then re tape it.....

Loving the BMW in the back!!!
