Just saw the Malossi kit is available again.
http://www.treatland.tv/yamaha-QT50-YT6 ... 318007.htm this one has 45.5 mm bore instead of my 44mm. how much more performance would this get me?
Also this kit looks good for others wanting to go to 60cc.
http://www.ebay.com/itm/YAMAHA-QT50-60C ... e9&vxp=mtr only $85 !!
On my current setup what will Boysen reeds do for me?
Will milling the head to get more compression?
What will get me more power?
EDIT: Malossi is a bit optimistic with their 70cc.
Stock QT: 49.26cc
YT60: 59.61cc
Malossi: 63.74cc
For the price I'll keep the 60cc for now.
