GP125 WORKINGS
January 21, 2013

So here it goes… the GP125 is in pieces, the engine is out, the unnecessary road gear is in the bin, clip ons are 3/4 done and I’m studying 2 stroke tuning like a fat kid on a sugar high.
Some reference photos of the engine because I’m yet to see any decent quality ones online:



what is the purpose of the plastic gear?
The plastic gear is for the oil pump
I am studying the two stroke tuning book as well its bloody hard to understand
Two stroke tuning.. it’s beautiful. It’s very easy and very difficult at the same time. The workshop looks awesome. Love it.
