It's been 22 years since I owned a 2 stroke, my first ever bike was an NS125F in classic RW&B. I've now gone full circle and
just obtained an MC21SE.
It's a wee bit scruffy but they seem to come up so rarely (especially here in Oz) that I grabbed it
regardless. It's definitely been a track bike: drilled caliper bolts, millage too low, not been road registered for years, no service history etc,
So with that in mind and not knowing that much about strokers I have a question.
It starts easy and seems to run ok, but assuming the worst (it's been thrashed and not been serviced) what are the main things I should check/replace (in order of priority) to get it running sweetly/reliably? (it will only be used on the track)
e.g. new rings/pistons/bearings
Extra bonus question:
How can one tell if the cylinder linings are ok, or if they need re-plated? What are the tell tale signs of problems in this area.
And, is there anyone in Sydney that does this?
Thanks in advance.
Al.
