So is trbig.

myself...

Yeah, LOL, If you try REALLY hard you can git-er-done. ask trbig

At 45mph the best I've gotten is an inch or 2 of air.

850 FD mod...



I am looking into this mod for Molly... mainly because I drive 120 miles round trip to work and any cut down on her rev's is a bonus at this point in her life... 28,500 miles on her and I hope she has many more yet to share with me... looks like I have a little leak going on... goodgreif...

The gas from the '70's and early 80's is MUCH DIFFERENT than today. I had serial number 254, so I DO know what these will do. The problem is the fuel now has a LOT less BTU's because of the ethanol they put in it to keep it "clean". I was able to bring the front end up in all 5 gears, but now it's three, and that's a fight. Bikes STILL pull like a freight train, though.
The 850 final is a good mod IF you do a lot of highway riding. You will find you shift just a bit more, but it's worth it to some of us. First gear is a little higher, but it's still lower than my stupid BMW.

[RichW1064]

yep...

lol... throw a 110lbs big mouth on the rear pad and simply tell her to be quiet... she is on the mile... lmao... if the light makes it's way then we (she is yet) are free.... (to my Brothers in (every lands)) Is she still holding on..?

pup needs water..!

1/4 mile friend...

his ole lady was so afraid she couldn't scare him down... best day of my life, she probably is yet a vocal professional... i do wonder if she has my number..? lol..? would love to talk to her again...

Hey again,

Another thing to consider is that the Special has a 1" shorter rear wheel, so you loose a few hundred rpms right there compared to the Standards 17" rear. SO...if you want to lower the rpms a little more, along with the 850 FD, you can also put on a Standard Rear wheel/tire. However, the Standard 17" has less variety of tire choices than the 16".

Now as to your friend, the Special running the 16" rear gave him better leverage to get the front end up, along with the extra passenger ballast in the rear at the rear tire provided additional leverage to bring the front end up.

Like Greg, I, too brought mine up to almost vertical during one of the 3 drag tune and time runs I did many years ago...had it revved to 5K and accidentally dumped the clutch too early, was able to hold on, but just barely, got it back down to earth safely. I'm running 4" extended forks on mine, and my rake/trail was reduced a couple of decades ago due to a front end collision that bent my frame/steering neck unbeknownst to me or the repair shop. SO the front end sits up a bit more to begin with, so it's easier for me to get it to wheelie than others. But that will changed once I complete my frame swap to an UNBENT frame.

BTW, here's an image of a skilled rider having some fun back in the 70's!

these things can and will surprise you... you do know this Greg... 1981 I watched my friend with a XS1100Special walk down the expess at 70mph on simply the rear tir for nearly a full mile, with his best sitting on the high seat, puzzled and amazed, happy to get off and find the girl's room... stock and all balls..!

Put a couple hundred lbs. of counter weight on the rear and that is a "condition". Feel sorry for his SO.

[RichW1064]

know when...

to lift it up... (rev on)

[RichW1064]

Brother...

If you can do that you aren't on an XS. These bikes weigh over 600lbs and the engine torques forward pushing the front wheel down. Not impossible to pull up the front because under the right conditions I've stood mine straight up, but pretty difficult to do in a normal situation.

here's where I am going...

Rich,

The 850's only have 5 gears also. The Final Drive ratio is taller on the 850s, so the driveshaft turns fewer rpms for the rear wheel to turn. The 1100's is slightly shorter, so it takes a little more rpms to make the rear wheel travel the same distance.

SO...putting the 850 Final Drive unit on the 1100 allows the crank to turn less rpms while still spinning the rear wheel fast enough to maintain the same road speed. The 850FDs are built better/stronger than the early 750s', and that's why they are preferred to perform the swap on our bikes.

People just say that putting the 850 FD on the 11 is LIKE getting a 6th gear because it lowers the rpms by ~4-500 at the same highway speed.

T.C.

love the bike... love the brothers.... throw out a hug for the sisters... time has come to re-design the XS/XJ finals from pony to ground... every bike has the ability for "your drive" needs... built into it..!

we need the engineer's to stand and be counted...

and besides... at 2k rolling 45/50mph, you can lift these giants off the ground... drivers beware if you are in control... lol... (be in control!)

these things are strong...

once a 5 speed...

always a 5 speed... so if I consider changing the ratio at the gear drive, then add a tooth to the final drive I could in the essence be rolling in 2nd/3rd gear at 50mph reading a tach message that reports 2000rpm... possible..?
