One of the interns I had from Germany was into 50cc scooter drag racing, which I guess is big in the Southern Germany. He had a couple friends that race in a stock chassis class, that had RZ engines in them and another friend was building a stock chassis, modified stock engine class bike with a stroker Puma barrel (that I helped him get and sent to Germany). :geek:

I like it. :geek:

There aren't any available from what I know for Banshee......

For what it's worth: Patenting such things doesn't make much sense. You will never get the ROI on such a thing and by the time you actually got a patent, that cat would be out of the bag so to speak. You are better off carefully marketing such an item. :geek:

It wouldn't run without them if it is an OEM Banshee engine..............

Good write-up! :thumbsup:

It's still going on........... That thread about running a 421 cub on an OEM keeps showing up with someone new wanting to do it about once a month.

Twister 5mil. It's the same as a 4mil except (doesn't require case work): it's billet, costs more, and cyliders need to be ported for it. :geek:

The best I did was the following when I was still in skool. *OEM welded crank balanced with entire rotation assembly. *OEM remachined head. *OEM carbs bored out to 30mm and bored for larger slides (not worth the time and effort). *OEM cylinders with sleeves pressed out, casting and sleeves ported, then reassembled (done on a live 4 axis CNC mill). You could consider it a hot dune port by industry standards. *OEM pistons machined to be equal weight. *OEM rods machined to be equal weight. *OOF handmade pipes. *OEM reed cages, ported, with CF reeds (I made the reeds, which wasn't worth the effort). *M100 fuel w Castor 927 oil. *Dyna ignition w/ OEM coil. *The radiator and cooling system in the test cell was used with an electric water pump and thermostat set at 190 degrees. The engine ran for ~10 hours on a Super Flow water brake engine dyno (driven off of the crank). It failed a reused OEM crank bearing at about that time. Peak mean horsepower was 101hp and I can't remember the torque, but I can try and find my engine build book for the engine if anyone cares.

For anyone who cares, the Dynomite dyno is made by Land & Sea. They are good dynos and should be labeled with this: Land & Sea didn't take that idea from one of my engineers at a previous employer. :biggrin:

Cascade will be (is) making towable vinyl covers (not sure about canvas). They are probably greater in cost than Cabelas.

Those are two good points. Chromoly tube doesn't necessarily mean the arms are of good quality, but it takes a bit more skill to work with and quality tends to follow that. Additionally, the lowest quality out board heims that I would consider running run about $65 per joint direct from Aurora (I am running the Janssen/Fireball outboard heim setup).

The one thing I didn't like about a couple Verde covers I had on my old trikes was that they didn't fold the edges of the vinyl under on the expose area of the seating surface where there was a pattern change. It would give you the perception that your pants were catching on the seat..... It's defintely not a big deal, but if they would have "hemmed" (for lack of a better term) the covers would have been much nicer. :geek:

I don't feel that machining the inner hub for the 8 plate rig is the way to go. Hinson makes the best parts (from an engineering standpoint) in the business. If you have the cash, then I would recommend using all of their parts for your clutch. You can't beat their coil spring cushioned clutch basket.

If you are not on a bar, I would suggest the staggered tires. I ran a generally similar setup on my old 10mil (potentially a little more power), and the only way the 14 paddle Rippers I had would do their thing was on the bar. The 16 paddle SLS staggered tires were the weapon of choice for hill shooting without a bar. I would suggest a longer swingarm if you are not running a bar. I thought I knew better when some folks suggested otherwise, but it turns out that I did not.

Cascade can also make you anything that you can think of........... :thumbsup:

I don't have a pass for labor day. I need to see what my normal riding group has in mind. :thumbsup:

Yeah, I am confusing the two events..........

Cascade can put a mean 10mil super cub duner together for you. :thumbsup:

Word. That doesn't look good from a craftsmanship standpoint.

I am sorting out a company trip to Florence towards the end of August. Otherwise, I am always down for a day trip to Sandlake. :cool:

I can't make it..................... The Cascade and Twister folks will be down there though. :thumbsup:

I used to live in Irvine. I was always surprised at how few members were from there compared to the number of Banshees out at the dunes down there. :geek:

I think they are all one piece, but one version has petals that separate about half way up the reed. :geek:

Fuel lines do not have to be level. You just want to eliminate high areas that trap air. A Pingel valve is a waste on OEM carbs assuming your OEM petcock (funny word) is in good condition.
