Description
High Performance Big Bore Crankshaft 61mm "forextreme" GY6 125/150cc 152QMI 157QMJ
- 61mm stroker crank, Increases standard stroke by 3mm (+3 mm stroker crank)
- Strengthened connecting rods
- Increasing storage
- High-quality Japanese bearings
- Free up for GY6 engines and 152QMI 157QMJ of 125 180cc
- High Quality
- Reinforcing implementation
- Good performance gains through more displacement and higher compression
The manufacturer recommends the use of 3 Bottom gaskets Sion is a co-location of the piston to prevent the cylinder head.
Instead of the extra Bottom gaskets, we now offer to match the GY6 Racing crankshaft Alu spacer with about 1.6mm height as Eko Meble solution! Please order if necessary!
Can be a little demo video of the performance and a possible setup find them here: www.forextreme.de / FORUM / index.php
In some cases motor must be connected to the back of the oil pump, so the oil pump housing, some mills are ground away / so that the crankshaft can be rotated freely. Please check before installation and, if necessarily to grind the crankshaft can easily rotate freely.
