So I bought Athena's :

HONDA CRF 150 R
CYLINDER KIT, PISTON,
GASKET KIT
BIG BORE 69 mm / 163,5 cc
2007-2009

P400210100023

kit and I was having some difficulty sliding the piston on with all 5 rings that were included in the kit, :pissed: even though the service manual is showing me that there are only four needed? :bang:

Is there a special way to do this ? I've tried using oil and watching other videos and all show people just using there fingers and it slides on in, but with mine I'm always getting hung up on the "Spacer" Ring. :uh:

Do I really need it? :fft: And do I need the after market camshaft for it or will my stock one be okay ?

I can post pics or whatever, or if anyone lives in the Lake Tahoe area I could buy you some beer to help! :cool: Thanks for your time.

They don't use locator pins on four-stroke pistons.

ok so i figured it out btw ... Athena emailed me back and said the 2 thinner rings surround the spacer ring to create the oil ring.

One of the other rings goes into the top groove for it and the oil ring goes in the bottom

yes they did, i have the service manual but it doesnt state for an aftermarket piston that comes with an extra ring of no use ... check this out... Athena in Italy sent this to me proving that they give you one ring too many
