  Things are not going my way. 180km into break in I spotted 2 small holes on the cylinder. I have spoken to the company I bought the kit from and they will contact Athena for assistance. Hopefully this ends well.. https://youtu.be/JSdh4gz1p8w

  @andrewj1680 said in pinning power valve parts needed: You could always just stick a big washer behind the bolt that runs through the middle you can lock it off that way which is what I have ended up doing today as since having port work and the power valve modded it kept moving a little over fully open I ve bought the servo kit I can use the standard parts to pin it now or if I can get the servo to fit my frame I will use it (the dt engine is in a different frame ) its gonna be a mission to get the servo to fit I wanted to mount it under the tank but the cables are too short not sure it will be worth the hassle

  If you really want to learn more about it then I recommend reading Graham Bell's Two Stroke Performance Tuning. Very good book and will explain a lot.

  @MIGHTYMAN said in Best piston: Think you mean Mitaka @Biker_123 ! I would definitely recommend this. http://www.ebay.co.uk/itm/271007694130?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT Purchased the listing a couple of weeks ago when I found out it was the place Norfe used to use back when he was offering engine rebuild services on the old forum. Remove everything from your barrel, stick it in the post and you will receive a re-bored barrel with the correctly sized Mitaka piston + gaskets in just a few days. Excellent value for money. £61?! I paid more than that back when I was 16 for a rebore and crappy new piston for a SYM Jet 50!
