”Then all hell broke lose. I kept the main engine cradle, forks, rims, and engine but everything else is hand built. Originally it ran with K&N pod filters acting as the air filters. As luck would have it 2 strokes actually run horrible with pod filters. The R5 uses the dead air room in the air box to pre corroborate the air. (This was explained to me and I still don’t know if I believe it or understand it fully). So like everything else on the bike I decided to build on with a similar volume to the air box. Did it help? You bet it did. Currently she runs like a champ.” -ABC.
