Dong Fang DF 250 RTB Bobber Information

[axa]

Did the reverse tube air ram mod today, and while i wont make any recommendations after just one test run, it seems as this may solve my top end sputtering problem.

It also seems that i was ever so slightly better able to hold a bit more speed on slight inclines.
But again i will not draw a conclusion until i make the same run to work and back a few times.
These settings are so subjective and subject to variables, the only way to be sure is over time.

I haven't change any jets yet so i probably should kill the engine, pull the plug and take a reading before deciding what to drill out the main to.

i was a bit skeptical, but i think the proof of concept is valid, i will be looking for a decent air scoop to try in the future.
