Yes I've seen them mounted that way. As a matter of fact this Gixxer 1000 damper I have was originally mounted that way. But I couldn't do it on this full dresser because the fairing hadn't enough clearance. So Mounted it with a fork clamp below the fairing and welded a mount point to the fairing frame.

Actually I put the same damper (Gsxr 1000 damper) on my ZRX1200R. It is mounted to the neck of the frame below and behind the steering head bearings...and to the right fork via clamp. I bought a kit from a ZRXOA member that was made to adapt a Gixxer damper to the ZRX. I spent about $100 on teh kit and $25 for a used damper off ebay.

Compare that to a Scott top side dialable damper for $400 and you got yourself a real bargain.

Thanks Maximan .. .Being that the mounting points will be wielded in place I have to get it right the first time. I also got my damper on e-bay. Was new in the box and cheap.

Mine is welded to the fairing brackett that goes across the center of the frame. The damper is bolted to that point and a fork clamp on the right inner fork tube.

I had to attach the damper to the fork tube and turn the front wheel side to side while holding the damper and rear bracket next to the frame to determine the best spot to weld it.

I welded it in that spot...bolted it down and the first time I rode the bike with the damper it made a huge difference in the front end stability. It was even more drastic than the fork brace...especially for this big heavy full dresser. The $25 Gixxer damper was absolutely one of the best mods I have done to Zilla's chasis.

partial results

The Sansei of Dojo Eleven left my place this morning. Dan Hodges is truly a jewel of a guy and a real asset to this community. I can only hope he hangs around here a little more often and helps other less experienced types to solve their problems Eleven.

We pulled the plugs on the XJ1200 ( ) and all looked good except #3. It was gas fouled and we could not really see why upon disection of the 36mm Mikunis. It may have had a little trash in the float valve. We did find one different jet. All mains were inscribed as 112. All looked the same except #3...(go figure). It was scored 112 also but looked different from the others. #3 has a ring around the head of the jet. Some one told us that was a dynojet. If so that may well be why #3 was running foul.

In any case I found it interesting that we didn't have to go down any jet sizes or make any adjustments to the carbs after installing the Supertrick exhaust. What is so surprising is this; the Supertrick setup appears to be flowing about as well as my 4-1 header with the gutted R1 can.

Sansei rode Zilla and commented on the bottom to mid range torque saying it was one of the "torquey-est" Elevens he'd ever thrown a leg over.

If you recall the 4-1/R1 combo spun up 94 HP and 69 ft-lbs on the dyno. Tomorrow I will try to get a dyno run with this new exhaust and see how much power I lost...if any. But I know this...the bike has taken a HUGE gain in the bottom after installing this trick exhaust.

Stay tuned...same bat channel....same bat time...

im happy its going well lol its 2 am and thats all i had to say.

Dyno results

WOW was I pleasantly surprised with these results.

I finally got the bike tuned to nuts. Took it to the dyno this morning expecting a nice gain in the mid range grunt and a little loss on top.

What I got was a whopping gain in the mid range and a GAIN on top to boot!

My peak torque fell by one half ft-lb. That could be statistically insignificant...it is certainly practically insignificant.

What so impressive is the 12 ft-lb torque gain I realized at 5200 rpm! You can readily see the boost in the torque from about 4K all the way out to 6200. And I gained about 5-6 hp in the same RPM range.

The icing on the cake was the apparent 1.1 hp gain. In any case my fear of losing a little on top was unfounded. I lost nothing.

Kudos to Sansei Dan for the idea of coupling a SuperTrapp core with this Jardine Spaghetti pipe. I'm sure Dojo Eleven will be ripe with conversation this morning. Who would've ever dreamed this thing would have actually gained top end power with tha much kick in the mid range. But then to be honest Dan predicted this might happen. He is a big believer in the SuperTrapp core and now I know why.

Here's the graph comparing my Aug 06 run with the 4-1/R1 versus my Aug 07 run (today) with the Dan Hodges SUPERTRICKK idea.



Here's the interesting thing. For grins I pulled the air filter to see what would happen on one of the runs. The bike went SOOOOO lean it cut out really bad and only made 75 hp!

Guess what's next XSives? That's a right...I've got to figure out some Supertrickk intake and get rid of this stock air box so I can jet up and get the extra ponies. We are already formulating a way to do it and still be able to ride 1000 miles in the rain.

Stay tuned...this may get real interesting...

I thought torque curves crossed hp curves at 5250 revs, and that big hole between 3000 and 4000 is unacceptable on a road bike, open the throttle at 3500 revs and no power? No thanks. As for the glaring carburation issues, well I ain't even gonna go there...

I've always wondered if the "pre-filters" used to cover the flame arrestors, aka pod filters, in modified jet skis could not be applied successfully?

[HobbyMan]

WOW,
Awesome mod. Once again you have proven to the rest of the group what technology is out there and waiting to be adapted to our bikes. I wish I had the ability to do things like this. Keep up the good work.

I drove 1,000 miles round trip this past week to check out Cody's bike and it's every bit as slick & trick as the pictures suggest.I also rode it around the neighborhood (Cody's Estate) and it pulls like a John Deere tractor from 1500 rpm up in high gear and he has that 750-850 FD with a monster fairing,hard bags and so forth.I looked at the posted dyno chart and I believe I saw something like 55 ft. pounds of torque at 3,000 rpm,not to shabby.It took a slight dip at about 3500-3800 but it still showed 55 ft pounds.I suspect that a set of K&N filters like those used on the FJ1200 powered Legend cars would with a couple more tweaks put Cody's bike in the 100 hp range and if that is not impressive I don't know what is. I have the trickest Eleven I have ever seen and Zilla is as trick as mine less some exhaust cam and a hundred pounds more weight and that 850 FD. An engine is the sum total of it's part's, how those parts are machined and assembled. It takes more than a big bore kit and some one off carburetors to make a 100 hp in an XS Eleven. I always give positive credit when it is due and in this case I believe Maximan has created a winner. The term road bike is a misnomer as all roads are not created equal and cruising at 85-90 mph on the inter-state across the vastness that is the western United States is a unique experience and begs for a tall gear,lots of horsepower and a couple of gas tanks.

Patrick..to put it bluntly...

YOU'RE AN IDIOT! Do me a favor and just stay away from my threads. I'll do same for you.

Didn't your mother ever teach you the golden rule:

"If you can't say something nice don't say anything at all."???

SO.......Don't go away mad................just go away........

Dan

We're already on the same page regarding the FJ1200 filters. As you know the ones they use on those Legends machines are oval K&N. Pugh uses some sort of all weather sock over the filter. They race in the rain frequently and he claims the filters never get wet enough to effect performance.

Considering the the bike went totally lean when I pulled the filter...and only spun up 75 ponies...it appears there maybe still more room for improvement. And like you said I think with the prescribed filters and a re-jet...Zilla might...just might...break into the triple digit domain.

Thanks again Dan for wonderful and creative suggestion.

[MAXIMAN]

For the rest of you XSives that may be actually thinking the torque HP curves don't cross in the 5200 range...look close again people.

The torque scale is on the right from 25 to 70

The HP scale on the left is 20 to 100.

Due to the different scale it appears to the common idiot that the curves do not cross at 5250. But since you all are XSives you are not common idiots and have been taught to read a simple graph.

At 5250 the HP of the Supertrickk is 66 hp. The torque curve is the same...66 ft-lbs.

Ahhh...the wonders of a government education in NZ.

Wow, good job Cody!

[petejw]

hey max nice work,
so the only difference between the 2 dynos
was the exhaust change?
if so thats a big difference.
did u muck around with the super trapp plates as well
removing/adding them?

if u do use the pod filters, i wouldnt
worry about water saturation/weather proofing,
ive had mine saturated after washing and it never seems
2 b a problem, at worst the bike mite suck in a little water
but that wouldnt b a problem.

[pggg]

Truth is they're pretty mediocre numbers for an allegedly souped up motor, big bore kits, skimmed heads, hot cams, port jobs, hell I've seen dynocharts of basically stock standard XS11's kicking out 90 horses, no sorry, even an idiot can see theres not much bang for buck there..
