I haven't determined the price yet cause I'm trying to figure out how much I like you guys. No I haven't figured out a price cause I need to find out what it takes on machining one of the pieces so its a nice bolt on kit. Plus I have to see if the guy I want to machine them wants to do it all the time, and I need to see if he's going to mass produce the backing plate. Man, the guy.
I buy everything Branson does to help development along on the 175's, also to try and make the power he does. I honestly bought one just to eye it, touch it, and sneak it in to bed when Sonja wsn't looking. I was not impressed with the idea, especially after the time I spent making the crank triggered Pertronix. After taking a look, its much smaller then I envisioned, much lighter then I thought, and lot simpler of a setup. Not to mention the fact of no battery weight and no pain of charging hassles. So I will be running mine by the end of the season and will probably be selling them for 175's, and 350's eventually.
Putting on the Dunlops and bigger carbs were this seasons money/time investment. The PVL would be good to do over this winter.
And then I can point to my spark plugs and say "see these- they're triggered by my crank" when the neighbors stop by.
Those Dunlops mounted up really easily and are straight. The front needed no weight to balance and the rear was so close it wasn't worth the trouble.
If there is a problem I can supply mounting plates to Aaron. I think we use different designs though.
Also PVL users must decide if they want to use a block off plate or not, to isolate the left side of the engine from oil flow. May or may not be necessary, I use one because it makes timing adjustments a breeze and keeps the PVL clean. The plates I make are about $60 each.
The whole project is kind of pricey...but in my opinion it's the last step in turning a 175 into a real race bike. You guys will have to take a look at my bikes and Hiroshi's to decide for yourself. With the PVL installed you end up with basically an engine, frame and wheels. Very clean, very light, and trouble free. No battery of course, which means no battery box etc, wiring is simplified, no on/off switch...just a push type kill button. Coil and CDI unit are tiny, with proper connectors already in place. If you find yourself jealous of the factory "GP" bikes like MT, TA's etc then you'll like the PVL. It turns the 175 into a four stroke chain saw..push it starts..hit the button it stops.
Typically you can lose at least 5 lbs or more in bike weight.
Not to be pricing Aaron's parts but...no the PVL system is not around $700...I'm guessing closer to $500 including block off plate and mounting plate. If you didn't use a block off plate and made your own mounting plate then maybe around $400.
For weight reduction you can subtract your battery weight, whatever battery mounting system you use, and about half the weight of your coil. Then add about 2.5 pounds for the PVL stator, rotor, mounting plate and block off plate if you plan to use one.
And...once you get down to a light bike...$100 a pound isn't bad. Figure alloy rims cost you about $120 to save a pound on each wheel. Glass tank will cost you close to $100 a pound. I WISH I could by weight reduction at $50/pound right now...I'd buy 20 lbs worth.
I'm using 24mm carbs I scavenged off an SL350 with Bransondapters to mount them.
I'm looking forward to seeing Hiroshi's bike at the Hawk school and hearing your impressions JohnnyB on how the PVL works in your bikes. My bike being a vert would take a different mount I'd guess, if such a thing is offered.
