Shreddr's HP2S Big Bore Dyno Result

By the way Rika said that you told him that you are not entirely happy with your bigbore ...

you are really stirring the pot here. "they" is Rexxer in Germany, and I never told Rika anything of the sort. I shared my dyno results with him and inquired about the Boxxer Burners. He mentioned that I probably needed an increased oil delivery modification before going for anymore power. If that constitutes being not entirely happy well then so be it.

I am very cognizant of the fact that the "Wossner Klan" is not too happy with my skunk works effort. If they would have sold me the frickin pistons and rods when I asked perhaps they wouldn't be talking trash about someone who figured out how to work around their "system"

please keep your conjecture out of the forum

Making them bigger, straighter? Is there an after market oil pump available?

Hi Jeff,

first of all there is no woessner clan. Woessner is a manufacturer of pistons like CP Carillo or pistal or any other company. Woessner has absolutely no issue with anyone doing his/her own business and sells their stuff to anybody (through licensed distribution channels or direct - if there is no licensed distributor). Some people just pretend that they have certain rights or exlusivity ... The proof is that Mr. Kurt Roesner - who has the exclusive distribution within GERMANY (and nowhere else) and ONLY FOR BMW pistons sells to anybody interested and not only to Rika or fralind - who may pretend that they are the only one to be able to lay their hands on Wossner products ... Probably the only person to have any rights (with regards to the development of pistons related to BMW is Mr. Kurt Roesner).

I told you before what kind of weird stories a fralind is telling about your bike ("I have made both bikes from jeff who sent both bikes over to me in a box") and I have just quoted what Rika has said ("you - Oliver - have no clue. Jeff has told me that he is not happy with his set-up").

I am not making any conjectures. Why should I? I have absolutely no interest in this. I have no HP2S and I am just trying to realize my own bigbore with Woessner parts which I have bought and for doing so I have come under massive attack by Rika and fralind - who both follow their own interests. Thats all. But these two individuals are in no way connected to Woessner. They are just users who bought themselves Woessner parts and pretend abroad that they are the only ones to ...

And by the way Rexxer is a company called Daniele Moto who does not do any bike-specific programming. They have service points in many parts of the world (the addresses in the US you can find here :: RexXer ECU-Tuning ::

Rika for example gets his mappings done by a service point in Germany called MKM bikes and I got them done by a service point by the name of Rehcing.

I have no interest nor do I need to make any conjectures.

But I am somewhat amazed by your reply. Woessner sells to everyone - through their distribution channels. It is quite normal that any foreign manufacturer uses certain distribution channels (which in the case of Woessner happens to be Maxmotors). Hence you could have bought from them but you did not like their price-tag. Fine. But don't blame them for not selling to you directly if they have an exclusive distribution contract in the US of A. It is the same if I wanted to buy Carillo parts here in Germany ... And remember it is not Woessner who is talking trash ... It's just certain individuals who are not connected to Woessner and who have nothing to do with the company Woessner and who are just following their own interests (or just trying to make themselves "important").

Oliver

The Rexxer I referenced in Germany was indeed Daniele Moto, and I worked directly with Chris S, who runs the show.

The R12S pistons I bought directly from Wossner when I found out about their availability. The big bore pistons were another matter, which evidently was a design contracted by R&R with Wossner. Wossner would not sell them to me and the US distributor didn't even know of their existence. R&R wouldn't sell them to me and told me to work with Max, who was more than willing to sell me a kit for $5500, which was ludicrous when I had bought the same parts for the R12S for only $1400 (sans bore job).

I am sure it is just business that got in the way, Max had an agreement with Kurt and that was it. So my alternative was to go with my own sourcing, and CP Carrillo is not too shabby here in the US.

Hi Jeff,

that price tag is so riduculous that I would have done exactly the same as you did.

Daniele Moto are the right people to contact. However they will be able to provide you only with a standard mapping. An individual mapping according to the specs of your bike requires a dyno. I remember when the mapping for my R12S was done there was approx 15 dyno runs until I had the perfect mapping.

Cheers
Oliver

[shreddr]

My first Rexxer map was for a base HP2S with Akrapovic, which was a major improvement over stock. The next map was tweaked for the big bore, and the current map was a modification based on my last dyno run with AFR trace. It spins like a top!

[omg1010]

Congrats!!!

[fralind]

Jeff, you need this for the best result

[shreddr]

I am all ears! What about the oil delivery?

[fralind]

The rotor and the screws you get at BMW.

The 1 mm spacer plate you can leave you lasers made ​​of aluminum.

Take the removed Oilpumpe as a pattern for the shape.

[omg1010]

The oil pump consists of 2 rotors. One 10 mm and one 11 mm rotor. The trick is to replace the 10 mm rotor with its 11 mm counterpart (thus making it 2 rotors of 11 mm each). The difference of 1 mm requires a spacer to be laser-cut (outline of the pump itself) from a piece of 1 mm aluminum metal sheet. As a result you get an increased oil-flow of 10% .

But I am not sure if this applies only to the R1200S or also to the HP2S.

Brgds

Shred. I am getting rid of some very nice things. Do you think you will ever run your bike in the standing mile, such as the East Coast Timing Association conducts? I bought a NEW, in the box, racing rear drive for my HP 2, almost immediately after I got it. It is new, factory, still in the box, and never installed or used in any way. With your bike in the tune it is now in and with this rear end installed, your HP2 would be able to run at least 179 with a full tuck rider. It is a 2.62 ratio as compared to the 2.75 you now have which makes your bike good for about 168. These mph figures are at redline on the 168 (stock) figure whereas the 179 figure is at below redline RPM. I will sell you the rear drive for 1750 which is 350+ less than it cost me. I pay shipping.

[fralind]

Jeff, what bearings run in the Carillo connecting rods

[shreddr]

Frank, I am using the HP2S bearings. Recall in my thread I had to remachine the Carrillo rods to accept the HP2S bearings as they were not the same notch as the R12S bearings.


remachined Carrillo rod to accept HP2S bottom end bearing

Dr. Curve, although 179 mph in full tuck sounds very appealling, I will be satisfied with the 168 that the stock gearing provides for my street purposes. If I ever head to Bonneville I will reach out!

[fralind]

Thanks for the info.

You should at the motor performance make the oil pump conversion.

It is not so a big expense and the distance plate is made ​​quickly

[shreddr]

for thos who have not seen the oil pump modification:

I assume it is part # 2 and 3 that are the 1mm thicker items and a 1mm thick "gasket" needs to be fashioned (laser cut) out of aluminum. Ordering the rotors is simple enough, but I am not sure who can make me the laser gasket.

[omg1010]

Maybe find a company in your area who has the necessary machinery to laser-cut metal sheets? Yellow-pages?

What's the part number for the 1mm aluminum spacer?
