Motorcycle Repair: Top End Rebuild, suzuki rm 100, repair manual

Question
My son is riding a Suzuki RM-100 two stroke motocross bike.

There is a rattle in the engine when running.

Our friends believe the top end needs to be replaced.

How can I get instructions to do the job?

Answer
HI Perry.
 The top end may or may not need to be rebuilt.  It may be a matter of doing a valve gap and timing on the bike, but instructions to do that and any other repairs will be in the repair manual.

Just remember K.I.S.S. and check the easy to fix before going into a rebuild that you may not need to do.

Good luck.
