scott

 

I have had the HPD setup and then just changed to AAEN. I really like the AAEN setup better.

 

I have the HPD pipe and clutch but I also have the reed conversion.
Before I added the reed conversion I had HPD's pipe and a Hotseat
clutch kit, airbox, oil injection removed and a 38mm TMX carb.
I only know how to ride and thats fast so the mods where okay
but still had too much lag on the bottom end. The reed conversion
made a huge difference but I still had a little lag coming from idle
to full throttle. I then removed the battery and starter and had
the flywheel race lightened. I have zero lag and this thing pulls
hard from the very bottom end. I have know way of telling what
the top speed is but I could tell when I was pretty much topped
out. I have a dirt road thats just over 1/4 mile long that I run up and
down and now it feels like its going faster the whole distance.
