#3Why go as far as designing and building a new engine and use old dated technology like push rods
Can`t see this thing driving anything but a cruiser type bike.
What I would like to know is were does all the money come from for a project like this ?

#4just because it is pushrod does not mean that it is bad technology, it means that the engine can be kept light and compact.
I dont understand why people think that it must be terrible as soon as pushrods are involved, some of the highest hp out-put engines (at the moment) are actually pushrods.
could you imagine how big and heavy this V4 would be with a quad cam? For not much of a gain either.
And if you even dare bring up harley motors I would suggest you dont, these are massive air cooled machines that due to the crappy metals used to cast them and the freaking massive pistons used (some are almost a litre per cylinder) combined with a stroke as big as a coma patient... ofcourse they are never going to rev hard or put out much power. That is a completely different argument.
That being said... the torque on those things are nuts.

#5The only reason a can see why they are using push rods is to keep the height of the motor down.
I still think you would best to go for overhead cams with buckets and shims for a high performance engines as opposed to cam followers, rods and rockers bouncing around at 9000 - 10000 rpm.

#6pushrods can be pokey!
...... top fuel dragsters are still, by NHRA competition rules, forced to use two valves per cylinder and pushrods and they kick out 8000hp!
Okay it would get tedious tearing down your bike engine every ten seconds but just cos its old tech doesn't mean it won't work......
