Seller seems to think that RC or V&H might have built this bike.....

Maybe... but judging from the pictures I have seen of actual RC/V&H bikes this is either an early prototype or someone's recreation.

Sterile Darryl? Did eight cylinders render his reproductive equipment useless?

coyotecowboy · « **Reply #3 on:** February 02, 2009, 11:13:26 PM »

I'd like to see that bike in person. There's a friggin ton of trick parts on that thing.

Is there only one oil tank for both engines? I'd imagine you'd get pretty good at clutch changes with two 836's tied together.

I wonder how hot that second engine gets.

Here's a pic of RC's 3 engined beast.

He had a 2 engined one that was even quicker. It was configured as a 2000cc v8

Sterile Darryl was Darryl Witt out of california. He was a drag racer with a love for show bikes as well, mostly kz900s/1000s. The twin engine beastie in the auction is most likely NOT an RC creation but it may have come out of "the Shop" Gary Perna's place in Cali.

If you look it is a street bike built using a mostly stock frame, stock carbs, car alternator, and a crank driven synchronizer belt for the street - doesn't really fit Russ's M.O. about the multi-engined bikes, he felt they were a handful even on the strip.

The only really iffy thing is rather than have two oil pumps drawing from the same tank the bike piggy backs the oil from one into the other engine - it works but not the way I would do it.

Wonder what ever happened to Gary Pena? He was a very cool guy. He had a 750 that was about 1175cc with nitrous, He would take it to Pomona to the NHRA World Finals with the nitrous removed and enter it in Pro Stock. He never qualified, but he got to run it in front of all those people for three days.

He is still around. Give him a call: Gary Pena @ 928-530-6666

He is Calif66 on this board (Ironically enough it is a post about another Sterile Darryl bike):

Jay, I Pm'ed you a while back about interchange between KZ900 and Cb450 pistons - do you have any kind of answer? should I re-ask the question?

Big Jay · « **Reply #10 on:** February 03, 2009, 10:05:34 PM »

E-mail me jay@aperaceparts.com. I used to make 1015 kits for Z1s using CB450 pistons.

Noticed something about Russ,s V8..
it has big barrels!, so to be 1000cc, it would have to be thicker sleeves than a 1080..smaller ID. Maybe he did it for strength?

found a black & white promo pic from Russ today, think I got it at a show at the RoseBowl in 81 or 82, looks like his double..

V&H had their FunnyBike at that show , wuth the lift up body..cool..

Geeto67 · « **Reply #12 on:** February 04, 2009, 07:52:03 AM »

russ cast his own cylinder bank. From what I understand they a very similar to a stock bank but with room for a large sleve that could accomidate up to 1100ccs.

Russ's injected blown single motor bike was "the Assassin" and was built in 70/71, His twin engined bike was "the Sorcerer" and it was built in 1976/77. In 77 he set a 7.30 record that held until 1989.

The 3 engined beastie was called "Atchison, Topeka, and Santa Fe" after the freight train and possibly the song about said freight train. It was built in 1973 and raced until the bike "tried to kill him" in 1976.

Out of RC engineering came Vance and Hines as Russ turned RC over to them in 1980 when he retired from racing.

This didn't get the press of earlier bikes, but here's Russ Collin's Battlestar rear engine Top fuel Honda.
This bike had a Goldwing motor, the photo was taken in 1982. The guys back then were not afraid to be different. This is why I like reflecting on the older race days. Russ was ahead of his time and this bike looked as if it were a handful.

I wonder what they did to beef up the frame and suspension to carry the extra load and stress. It doesn't seem like they did enough -- like the bike needs a stronger swingarm and shocks (look shot).

DrSummerOff · « **Reply #15 on:** March 30, 2009, 02:47:24 AM »

Whats the horsepower difference between a 750 with and without the 836 lit..approx.

Hello I am in France and after five long months I finally just get the 4-4 cb 750 two engines offered in auction on e-Bay . The seller is not very ccoperative and he has only told me than Terry Vance could be the builder of the bike. It's impossible to find anything about this bike on the net. If some one could help me , it would be fine... During next week I'll try to understand how the two engines work. For infromation, front engine has its own oil pump , belt driven. The belt between the engines is not supplied, there are only a part with the mark "sterile darryl".
Best regards from France and thank you for the help you'll be able to provide. Pierre

Welcome Pierre!!!

First thing we need are BIGGER pictures. You can emial them to me @ customerservice@mavrik-powersports.com

or

use photobucket or a similar hoosting service to link them here.

After that maybe scan any paper documents you have pertaining to the bike? The more information you give us the better we can help you sort it all out.

and again WELCOME!!!

Geeto67 · « **Reply #19 on:** July 27, 2009, 03:36:37 PM »

PIERRE1955,

if you look on the first page there is a phone number for Gary Pena. Call him and ask about it as he did a lot of work for sterile darryl and should be able to point you in the right direction for more info.

PIERRE1955 · « **Reply #20 on:** August 16, 2009, 01:04:39 PM »

Good news I have tried to start rear motor ( the one wih kick pedal ) . carbs are in correct condition , so I have filled them with gas , pluged a battery and after 3 or 4 times , the engine has started easily. No abnormal noises, it seems to be in very good condition and that's a good surprise.
Now I am trying to find a belt to activate front engine .

yes, maybe, but we need dynocharts with rearwheel HP and torque.

MAYBE ? You got to be kidding ! When the engine comes on boost, it's like the hand of GOD is pushing you forward !!
Dyno charts ? You can take my word for it, or not. I have nothing to prove to anybody.
