I found this about the Venture Mod
I am pleased to announce for our VR members a starter clutch mod that will last forever and put an end to that "Clunkety-clunk" that you hear when your starter clutch is going bad. I will let Squeeze explain it much better than I ever could:
The stock Starter Clutch is a one Way Clutch which uses three spring loaded Rollers the connect to the big 72th Gear Wheel which is the last Gear in the line of several Gears coming from the Stater Motor.
These 3 Rollers connect (in Fact they run) to the inner Area of the Wheel by spring Force and clamping Force. This whole Assembly sits in a Housing which is bolted to the Flywheel with 3 Bolt in M8 Thread. Over Time, these Bolts tend to get a little bit loose plus the Rollers and the Surface they're running at develop some flat Spots and chattering Marks too.
This is the common Scenario where the Problem starts to get heard.
If the Battery is cold and/or isn't in the best Shape anymore, the Rollers can't "bite" strong enough to the connecting Area and the Clutch lets go for a half a Turn. If The Rollers bite on a chattering Mark or a flat Spot the Connection they may hold on or let loose again. This Movement creates the hammering Sound and puts a Lot of more Force on the loose Bolts. This, of Course, allows even more uncontrolled Movement of the Clutch Assembly and a even more dysfunctional Clutch. As an nasty Side Effect, the Clutch can, and i know of two Cases where it actually did, cause the Starter to act as an Generator because the One Way Clutch wasn't a Clutch anymore but a solid Connection. This caused the Starter Motor to burn down on both Cases. I suspect a Lot more of these Cases, but there's not enough reliable Data for me to make a final Call.
I've seen a Lot of these Clutches and not one of them was even partially reusable. I have Buddies which tried to reuse some Parts, but they did the Job twice or even three Times in the End. I know a Bunch of Guys with heavily modified Engines, meaning 1500 cc Vmaxxes at least, and each and everybody of them had their Share of Head Ache in this Regard. The Record Holder of those is the Guy with a 1600 cc High Compression Motor who needed three complete Starter Clutch Assemblies each Season.
So, in the End, you have two Options to get the Job done
First Option is to buy a complete Set of new Parts, not just the small Set of Rollers, Springs, Caps, but also three Bolts, the Housing and the 72th Wheel, mount the Assembly exactly in centered Position to the Fly Wheel, red Loctite the Threads of the Bolts and don't forget to punch the End of Threads with a Center Punch. Then cross your Fingers, say a Prayer or both and hit the Starter Button after completing the Install. Feel good about the cheap (around 185 Bucks for the Parts) Repair but you need to keep the Procedure in Mind, because most likely you'll do that again some Time later.
Or
Second Option
Send your Rotor over to Dano in a 12x10x5 Inch Package, get it back with the Gaskets (optional), don't worry about having the Clutch Assembly mounted exactly centered to the Flywheel, just mount the Rotor and the new 72th Wheel and have a good Time while being a happy Camper.
This is because Dano will mount a much more sophisticated Clutch Assembly, which uses 18 Ellipses instead of three Rollers. The Ellipsis are spring loaded too and because of their Shape, not only bite at the 72th Wheel, but lock up the Connection between Rotor and 72th Wheel. Because of the ellipsoid Design, you won't need to worry about burning down your Starter Motor. I sure you weren't worried about that before, but it's good to be sure anyway. Not to mention, getting the Flywheel off the Crank Shaft can be a ... well ... how do it say this ... pita ...
Yes, this Upgrade is more expensive than Option 1 and it will need a little bit more of Downtime because of the Transit Times of the Parcel. But you'll be a happy Camper and never think about the Starter Clutch Issue again. Oh, except maybe the Times somebody tells you his 1Gen or Vmax produces a hammering Sound upon starting ...
Squeeze
Now for the nitty-gritty. All you need to do is remove your flywheel/rotor, send it and a check for $275.00 (US, VR discount and return shipping included, Canada shipping a bit more) to me and a couple of days later I will return it to you with the starter clutch mod already mounted ready to go back on your bike. You will also need to get the 2 left side cover gaskets and crush washer for the lower bolt on the middle gear cover. If you would like me to supply them, an additional $15.00 will be added ($290.00 total US). If you have any further questions, please don't hesitate to PM me or call me at 317-370-0139 anytime and I'll be happy to discuss it with you.
An additional note here for non-members wishing this mod- Price will be $295 US, gaskets priced the same.
