There have been some good topics on this.
This is very neat and tidy.
And the one Jean did. Gotta admire anyone who can mill using a lathe.
The idea I had was to use the whole intake assembly from a small bike (you'd just need to flip the reed valve over) and see if it would offer up to the crankcase.
This is from a Yamaha PW50. Retail prices are about $25 for the intake and $30 for the reed valve. SInce most (if not all) of the intakes will be 4 bolt it may just be a matter of finding an intake with the right hole pattern.
What I don't get is that CNW says on the 72 no modifications will need to be done to the crankcase but if this picture from Old Britts is correct the 72 only have a two bolt setup.
So I'm trying to do the math on the 4 into 2 thing. :?:
