I finished the complete fuelmap today for the V&H Widow exhaust system. I needed to increase the cylinder size to 76 CI to make it with the AFR and VE tables, but then you can adjust it.
Started at 05.00 this morning, needed 2 full days of 12 hours to make the perfect fuelmap for it. Then I filled the bike with enough fuel and hit the road (the throtle response s much better than Buell) the bike pulls like a V8 so strong and hard, it almost surprised me. It is a real fun bike to drive, wonder how it go's with new rear shocks, new triple trees with Cafe racer style clipons.
The new rearset we mount also solved the problem of heavy shifting. The biger 4 pistin rear caliper really stops the bikes. The feeling is smother and strnger I like it. I can't wait on all the other parts to mount. Different exhausts to test and the summer....
Update 09-11-2009:
So, woke up early this morning and fitted the oil catch can.
When I took the air box off last time to get the flapper out of the air box, I noticed that the vent hose for the head ventilation was a 2-1 system. They did it the same way as Buell was doing returning the oil in the throttle body.
What I didn't like is that the vent hose is disturbing my airflow to the throttle body, because it was laying on top of the hole there. (here is also a good point for making a new air box for getting more air in the throttle body, I will come back on this subject when I test them on my dyno)
As somebody who loves making nice fuel maps, I don't like a system putting moister, oil or other stuff in my, with love adjusted, throttle body.
So I took off the gasoline tank, removed the air box, took out the 2 breather bolds in the front and rear cylinder head and looked at them....
MMhhhh really small holes in there, I drilled them up to 4 mm and then used 1/4 oil hose to the breather, just for better breathing and to be sure it is not possible to get anything in the way for breathing as it should be.
I'm going for some test-driving today and see what comes out. I also like to see how much oil is getting out of the system. We tested these catch cans for a long period and they are now monkey proof as we say in the Netherlands. We use a 10 Bar resistant glass to keep it from braking..
Update: 11-11-2009
Okay, the QD full exhaust system arrived yesterday with thanks to the Importer Verheul, who was so kind to send us one for testing.
We mounted it and made some runs with and without db-killer on the dyno to see the results. It is not good, so we'll discuss the results first with the importer to see if can agree we post them here. Our relation is based on giving feedback to increase the performance, so maybe more news later.
And AST (Dutch Company who makes suspension) arrived with the rear suspension.
Before we discussed what we liked. A fully 5 way adjustable rear suspension with the possibility to use it as the best rear suspension for road use and to be able to adjust it and use it as the best suspension for the track.
So it should be possible to adjust it to different riding heights in minutes.
The stock version is able to get 3 CM (1,18 inch) adjusted with the lower mounting eye (see picture 2)
In the final version we will deliver a extra longer mounting eye, to put the XR1200 more on the nose.
We wanted to have a suspension that was able to fully adjust low speed compression, high speed compression, spring pretension fully adjustable, rebound and the length of the shock. (in our setup we adjusted it 2 cm ( 0,787 inch) higher than the standard shock.)
Okay, I went riding yesterday and the difference was huge. It did his work more than perfect, Because of the higher rear the slow and fast cornering was much more stable and controllable, Faster and faster in the corners (-; I went. Then the comfort, it adapted the bounces so nice that the next problem that I felt was my front suspension. It didn't do what it supposed to.. after some testing I tried with different adjusting to get it right but that was not possible. Okay, we found a solution for this problem also. We are more than happy with the setup now for the rear suspension for the XR1200. We also sell this suspension and AST made also the shocks for the Buell for us with lifetime warranty, so we also offer this for the XR1200. Spare parts available for this setup, so no problems. I will put them in the shop soon.
That's it for now. Later on more news.
Today I finished the Fuelmap this is really the final version:
114 NM (84 lb-ft)o f Torqe and 90.2 HP (91.2 PS) SAE Corrected.
Update 12-11-2009:
Some optical tuning.
We also fitted the Cafe racer triple tree with clip-on’s today.
I was impressed with the quality off the Free-Spirits Triple Tree, very nice with the red details
still waiting for the Magura Hydraulic clutch , and the braided brake lines too come in.
very nice detail on the headlight mount.
old school looks
Hyperpro steering damper came in
Oke 1 more:
Today we will test the Suprtrapp 2-2 complete system for the XR1200, And directly make the fuel map for it.
Fingers crossed (-;
Update 18-11-2009:
Oke I finished after 3 days the complete map for the Supertrapp complete system. first I played with all the disc. The factory says for max performance and Torque use 16 disc. At the end after testing everything I ended up with 18 Disc, and a open endcap.
This picture shows 1 open endcap and 1 closed for the picture. You can open and close it very easy.
When you both open them the sound is darker and a little louder.
When you like to order this part, go here: http://www.twinmotorcycles.nl/webshop/artikel.asp?guid=YXHFSC&aid=2594&cid=9649&s=&a=
Here is the dynosheet of the final result. 88,7 HP and 110 NM of Torque
Here you see 2 runs, in the same condition with the endcap open and closed. You can see (the blue line) that closed it will add torque at lower RPM. I also checked the AF values and the difference is save for running open and closed. I made the fuelmap for the open version. the difference is 1 HP and 2 NM of Torque at peak power.
Here is the dynosheet from the supertrapp (red line) compared to the stock exhaust (blue line) I tested before:
Here is the dynosheet from the supertrapp (red line) compared to the Vanes & Hines (blue line) exhaust i run before:
The supertrapp is better performing from 1500 RPM till 3000 RPM compared to the Vanes and Hines. Then from 3000 RPM till 5000 RPM the Vanes and Hines is the winner, and after that there is a small difference in Power at top end.
The next exhaust is the one from Free Spirit's can't wait:
Update 20-11-2009:
Now I first have to finish 2 bikes from customers from Polen. 1 of them is a 87 CI Buell XB12 S, finished it yesterday, here is the graph: It makes 115 HP and 131 NM of Torque Not bad at all.. very strong engine.
UPDATE 20-11-2009:
Oke we tested the Free Spirit's 2-1 system and we are waiting on the feedback if we can post the results.
Next week we will test the slip-ons on the stock header from QD and Free-Spirits.
Monday I go to Hyperpro http://www.hyperpro.com/ the full day, to develop a new rear suspension and make a upgrade for the front suspension.
After testing we hope too have 1 good solution from 1 manufacturer and payable. When you change something on the rear suspension you feel how poor the front suspension is. To provide a good solution for customers we have too do this.
Have a nice weekend.
UPDATE 4-12-2009 REMUS 2-1 EXHAUST:
Yesterday I started on a customers XR1200X bike with a REMUS 2-1 System on it.
The bike is completly stock, with a stock air filter and the Remus 2-1 exhaust DB-Killer removed.
And here are the results SAE Corrected: 88.6 HP at 7326 RPM and 104 NM of Torque at 3476 RPM
Here you see the Remus compared with the stock exhaust, BLUE is the Stock Exhaust, RED is the Remus:
I would keep the stock exhaust, and Tune it... (-:
And here is the Remus 2-1 system compared with the Vanes and Hines:
UPDATE 31-12-2009 XR1200 FILTER TESTWITH REMUS 2-1 EXHAUST:
We are testing 3 filters on a stock 2008 model XR1200. The bike has a Remus 2-1 system with Db-killer installed.
The testing conditions are done in 1 and the same day within 1 hour.
- Stock airbox
- Stock engine
- Remus 2-1 system db-killer installed
- Same tank of Fuel
- Stock ECm with Stock Fuel map (man it is bad with the Remus)
The K&N Filter is a car filter and NOT for the XR1200. It fits almost perfect but giood be better.
Oke below Run with stock filter, 82.2 HP @ 6819 RPM / 102 NM @ 3614 RPM, SAE Corrected
Oke below Run with Pipercross filter, 83.8 HP @ 6826 RPM / 101 NM @ 3848 RPM, SAE Corrected
Oke below Run with K&N filter, 85.5 HP @ 6839 RPM / 104 NM @ 3548 RPM, SAE Corrected
OKE CONCLUSION DON'T BUY PIPERCROSS:
Below you see the graph between the stock filter (blue line and the pipercross Redline
Oke below is a Graph with K&N (red line) versus Pipercross (blue line):
And below is a run K&N (red line) versus stock (blue line):
I suggest we wait untill K&N comes with the filter.
Happy New-Year and thansk for reading (-:
Oke, Last one, Just uploaded my stock map so now the ECM is mapped, have too look at fine tuning:
92.3 HP and 110 NM of Torque with K&N Filter
2010 Racing:
Update: 18-1-2010
We finished the coorporation with a Famous Italian Exhaust maker. We will going to make all the ECM's for them. With every exhaust you buy, there will be a 100% perfectly adjusted ECM available. It will be a trading system, send your old, receive a new one back. We also will do all the development of the Exhaust with them. We soon will test the first XR1200 complete slip-on system. Can't wait....
Update 21-1-2010:
Somebody asked me to show the difference between a complete stock bike and the tuned Vanes and Hines by me because he thought the improvement was not that good. I didn't had that graph on this article so here it is:
Update 26-2-2010:
Get ready for the fifth year of American style flat track racing on the European mainland!
With more races, more riders, better fights and more traditional flat track bikes than ever before,
the season promises to be the best one yet. Not only will we race in six different European
countries and is the cup extended to nine rounds, but we also welcome the new All American
Twins Cup in addition to the Mefo Flattrack Cup. Only big American twins allowed in this
championship! The All American Twins Cup will kick off with a double header on 1st and 2nd of
May in Lübbenau and Parchim. But you will have a chance to watch these big bikes before then at
the big track of Jübeck, Easter weekend 3 & 4 April.
The 2010 season will bring flattrack back to Austrian Heidenreichstein and Czech Marianske
Lazne, and to new venues in Germany, Czech Republic and the Netherlands. But we especially
like to mention the first round in Amman Valley, Wales, honoring the British riders with a home
race, and round five, which will see the first ever flat track race in Switzerland, home of long-time
cup enthusiasts, the Dutch Brothers. Switzerland will also host this year’s Nations Cup of
Flattrack.
More exciting news is that flat track racing is returning to Italy, the country where it all started in
Europe so many years ago. They will host a national championship with three rounds already
confirmed. Multiple British and European Champion, Italy’s own Marco Belli, will ensure high
quality racing from the start and maybe even Italian speedway legend Armando Castagna will
return to flat track racing! Castagna won the Harley-Davidson 883 class in Italy in the early
nineties.
All in all a lot of races all over Europe, so check the calendar on
www.flattrack.de and experiencethe original extreme sport at a track near you!
A big thank you to Mefo Sport,
1-3-2010 update:
We soon wil test the Exhaust for the XR1200.
We will also make a complete fuelmap for this setup and will test and modified it, untill it gives the best sound and the best performance (-:
19-3-2010:
Testing of the above exhaust is still in Progress, We remake the silencer, so far 112 NM and 88 HP, very strong midrange. I testride it and the feeling and pulling in the low and Midrange is very good.
Our own bike has the classic kit on it stuff is to the painter when finished we post some pictures.
The steering in on the XR1200 (roads are dry now) is very stable with the rear end 5 CM higher and the Hyperpro shoks in the rear. The front Needs to be adjusted, will do that later on but feels very stable but a little too stiff/hard.
When finished we start testing the slipons on the stock headers.
update 30-3-2010:
oke, we decided to first paint the bike black and then make stickers to play with different designs, and make
a final choice for the airbrusher, we think we keep this design.
The exhaust is ready, after development more results later:
Here is a picture from work in progress, front fender needs to be mounted and the front windscreen with small fairing, I think tomorrow evening more pictures.
Sneak Previeuw: Here is a graph of our 2-1 Torque Hammer System which is still in Development
Another boring day at the office:
Update 22/5/2010
Proto type TM Torqe hammer XR is ready for testing
Equeal lengt headers, nice lines, nice sound
now testing and tuning
ps. where a other fuw boring days at the office ;-)
NO. 16 From the Dutch Brothers ( www.dutch-brothers.com )
was sleeping over for a few nights , very nice bike, build to go sideways
