Swapped the thunder header out for this nice Hpi exhaust. Picked up 4hp and 2 ftlbs of tq along with a better fit and finish. Will post dyno sheet.

A fairly common issue on twin cam 110 engines. Heavy valve springs and cheap factory lifters=trashed engine. If you are out riding and start hearing a squeal noise it is best to shut the engine off and have it towed to the shop. Continued operation after a failure circulates the junk through the engine and causes further damage.

How does this happen? Bike has 10k miles 2 different head gaskets(MLS in front composite in the rear) and the front one is upside down not allowing the rocker to properly drain and spitting oil all over the place

Wonder what would cause the rockers to fill up with oil?
