It‘s not only the weight itself, it‘s the way its moved. The whole bucket moves all the way, while the finger follower rotates around its axle and only the tip does the full travel. Regarding your „what took them so long“ comment: Finger followers were ... more »

I was going to answer in the same way: Finger followers seem the way to go in high performance engines. I think the greater freedom in cam design and lower reciprocating masses justify the change away from the buckets. The advantage for a 450 is not ... more »

Shims between the valve and the finger follower.

Here's the Kawi head for comparison:

Both designs have been around for some time. One has a tilted resovoir to keep it away from the heat of header pipe. The internals should be the same.

You can see two bolts on the right side of the cylinder head. Those are the shafts of the finger followers. The changes are very similar to Kawi's new 450 head design.

Never tried the Mako, but I can recommend the PHDS. Had it on every bike since I first put on my 2010 150sx. Bought it mainly because of vibration issue (numb fingers), but found out that they work well when you overjump stuff and flat land. I think ... more »

Way to small for a clutch (assuming the power of the bike is in the 250f/450f range). It's a two stage gear reducer. Small gear under the Mugen logo, big gear and a small gear on one shaft where you think the clutch could be and another gear one the ... more »

Nah, no clutch. Bleeder screws for oil. The red cover covers the transmission from the motor to drive shaft.

Damn, good for him! You guys need to realize that he is a national hero in Italy. You can ask any Italian if he knows who Tony is and you‘ll get the answer: yes of course, what a dumb question..

Yes, all good points! They should focus on their 4 strokes line and find a modern architecture that sets them apart from the others (like the backwards motor on the yami, the airbox setup of the honda or the stael frame of the KTM) And they need to have ... more »
