I'm loving my 02 520 exc RFS engine, There rock solid engines, great tutorial . Thanks

[@mxgryan]

Ive always heard that about these. Thanks for watching bro!

[@egar1m]

Great video! Are you planning for a next part? The rebuilt?

[@mxgryan]

For awhile we weren't sure if this motor was going to get fixed or not. At the moment it appears it is, and I will do some more videos, although they may end up on the RTi Powersports channel.

I hawe exc 2005 250 rfs engine, i hawe valve problem, but the thing is they dont make such valve's anymore, dont know what to do. Any idea?

[@59plexi]

i have the 2008 RF4 engine...fast and mean...but prolly not as realiable as this design....

[@scottc4433]

Can tell it’s your first time with rfs playing with all those zip ties lol

[@mxgryan]

Not my first time, but only my 3rd or 4th. I'm definitely not an expert. KTM doesn't even do training on them anymore.

[@eduardtkachuk4347]

I'm rebuilding my bike also and after putting it all back together it would only backfire out of the carb and exhaust but won't start, why is that?

[@eray-23]

Engine Timing is off

[@stansus4588]

Check valves or could be bad connections on the black box

[@BigSlushi4k]

Can U rebuild mine
