Frees up a lot of horsepower. Chain is much more efficient. Shaft drive consumes HP that never makes it to the rear wheel.

I beg the differ not ALOT of HP lol just some. With my chaindrive and its a 1260 High conpression it was only putting down 135 some stock vmaxes with just exhaust and jet kit can out down 125. Yes a lot easier to maintain like not breaking drive shafts. But I think the biggest improvement is the not lifting of the bike when taking off. A lot better in the corners when accelerating. Just my thoughts

Yeah, my statement t is really just theory so you're right.
Be nice if someone chain drive modded a completely stock motor, then we would really know.
I wonder what the actual weight loss is by going to chain drive??

Less weight and power loss through the driveline. Easier to alter the final drive ratio to suit his needs. Fit a wider tire. Better handling if he decides he wants to ride it like its stolen. (there is a BIG difference in how the rear end responds between a chain and shaft drive)

Should be approx 15-20% power increase with ALL other things equal.
We've seen higher mileage stock engines made 132-133 rwhp. I've seen stock engines with good headers and jetting only make mid 1-teens.

So what's the advantage of shaft? My understanding is they're much smoother and easier to maintain. If chain is much better for a sport bike why would Yamaha go with shaft drive?
Why does it benefit the front end lifting up and the cornering? Because the chain flexes?

One of the things a shaft does is it lifts the chassis under hard acceleration which upsets the handling in corners. If you watch a pro stock car at the drag strip the Vmax's drive line does the same thing. It's like lifting up the middle of the bike under hard acceleration.
The shaft is cleaner, an rear differential oil change every season or two and grease splines when changing tires. The chain requires adjustment/ alignment, frequent lubing and cleanup of chain lube that "flings" off.

On my old XS1100, Yamaha had reversed the engine rotation to counteract the lifting at launch through the shaft. It felt just like a chain drive set up.

So why no mention of the alligator skin seat???? That's the best selling point of the bike.

Correct. A chain drive will push harder into the ground under acceleration. BUT, there is a lot of maintenance. Keep in mind that these were not designed as Sport Bikes. They are touring bikes that they just decided to add some power into.
The shaft drive is quieter (normally) and much cleaner.
Modern metallurgy and chains have become so much better that they don't need near the maintenance they used to. Still, they make a mess and are a hassle.

For about 30hp at the rear wheel, and the ability to fine tune the gear ratio.

This sounds like a plan! How involved /difficult is it?
Didn't consider the fact you could stretch out the gears, that would be nice.
I will say this, in my opinion the max weather the gen 1 or 2 should have been a chain drive. Why u ask, simple. It was designed for what, ,,,, the dragstrip, not for touring, but was put in the touring class.
We all have seen the video of how they came about the idea of the max. So my ? is why limit a bike with shaftdrive when you are building a dragbike. It didn't make any sense. You are robbin the bike of its full ability to do what is was designed to do. I would like to see a comparison between a stock vmax and a chaindrive only vmax.
I have always believed that a chaindrive max will compete with the sportbikes at the drags, the problem has always been the driveshaft.
I like shaftdrive, low main, quiet, it is great, but the problem I don't like is no rim selection, weight, loss of power, lift on hard accerlation.
This is for sure, as soon as I am able to chaindrive this 2012 Gen 2 I have it will be. I hate the drive shaft on it and want a better selection of rims, which I cannot get with the shaft.
If Sean can't do it Madmax or PCW wll. But it will be done real soon.
It is there saying, We build it and You make it your own.
My Own will be here soon. Chaindrive to the Max!

Remember guys that while the bike is lifting under hard acceleration that the tire is being forced into the ground... I don't like how the shaft will try to wash you when you are spinning but its manageable.. I actually have all the parts to go chain drive but I don't think I'm gonna do it now, I just like the bike too much the way it is and Jedi told me he'd make me a custom driveshaft when I was ready so I hopefully won't be snapping the stockers anymore..

I actually like the looks of the 2nd Gen Max with shaft. Then again, I would also want to stretch out the front with extended forks and a raked triple tree. That's just me though. Now the first Gen... HELLZ YEAH on the chain drive!!!I will say this, in my opinion the max weather the gen 1 or 2 should have been a chain drive. Why u ask, simple.

The arm is +3"?
Meh... I would prefer the stock length.
Unless I was able to find someone who had a stock length arm that would wanna do a straight up trade ^_^
It is and thank you!!
Still not sure if I'm going to sell it or not but if we don't start working some hours here soon I may have no choice...Sent from my ADR6425LVW using Tapatalk 2
