Check the spark plug is may not be tight enough, don't over tighten it as you will damage the head.
Replace the plug as it may be missing its oil ring.

Hope this is of some help.

SOURCE: what spark plug for yz 125?

I have a dennis kirk book, the correct spark plug is a --BR9ES--(NGK)

i always used SAE 10w-30 oil on all my dirtbikes,
no transmission fluid

for the chain you should move the back tire back until the chain is at a snug tension
