The next thing to fix is getting the frame rails under the engine level with the floor while you are sitting on the bike. This is the end result from the front and rear spring rates, rider sag, and the position of the upper fork tubes in the triple clamps. If the rear of the frame rail is +/- 1/4 ", you may get into stability problems. You may be on to something here. HD designs the front axle higher than the rear. 16" rear w 19 or 21" front (a 3" - 5"/2 difference). My tires are 19". I replaced the OEM shock with a 1" longer shock to clear the rear fender. The bottom line is I reduced the rake/trail. With a reduced trail the steering damper should be effective (but not the final solution)

I suggest start levelthat I have to check, and as you get everything else worked out, you can move from there if needed. One of the problems with the aftermarket suspension companies is that they do not take this into account when making their spring and rider sag recommendations. I have verified this with Roadsters, XL 50, Nightsters, but not with Customs with the 21" front wheel.

Then get a fork brace , Metzlers Got 'em, and the appropriate springs and other suspension related settings. Then add the steering damper.

How about a quick ride report before and after adding the 19" tires?

Would you believe that I never rode a Sportster. I'm in Norcal, bought the bike from Ventura HD, had it delivered to Storz, when finished I drove 350 miles to SF. I did rent a Vrod in Daytona for a couple of days.

Truth be told, I wouldn't have bought the bike if I rode it first. I'm a Beemer LD rider since 1972 and I never had handling problems like this before, even with my Brit bikes before that. But I'll do the best I can to get it right.

So how much of the Stortz stuff did you have them put on it? No, it will never be a BMW, but with the proper set up it can still be a very honest bike, for a middle weight cruiser.

A middleweight tourer is exactly what I wanted. I didn't get the Storz Forks. They weren't adjustable & the triple trees maintained the OEM rake/trail (but larger diameter). The Buell front fender treatment they use looks great, but the fender is tupperware and gives no structural support. I didn't care for their shocks, they weren't gas and didn't have adj damping (as I recall).

I got the tank, seat and rims wired, chain, exhaust. They really don't do mechanical work, just some bolt on - and they are neat and nice people to work with.

Lightbulb Ya know...

You really should have RODE your STOCK '07 883R before having it modded, it's nothing to brag about, but mine doesn't ever get any headshake problems, and I have it upto 110mph quite often
FYI- I have 10,000mi on my '07 883R now, and I've only had it 13 months. It's no Beemer, but it ain't that bad in stock form.

Thanks for the comment. Yup, Ralph is right. I just assumed that a manufacturer that's been in biz so long and the model being mature wouldn't have those problems.

Rags - Very nice. That was the direction I was thinking of going in originally. How about more details, how much do you weigh, what spring rates and length on the shocks, how does it ride now?

Here are my recommendations for set up:

1. Take the shocks off and make sure the chain tension does not bind up the rear suspension as the rear axle moves through a line formed by the swingarm pivot bolts and the center of the stock pulley. On a stock bike, 1/2 turn on the adjusters can make the difference between binding and not binding. Make sure you also get a good alignment.

2. Get a Superbrace fork brace.

3. Experiment with different tire pressures. Too high can reduce the contact patch and make it unstable, and loose braking traction, too low and the rim can bottom out against square edge bumps. I like pressures on the low side so I get maximum braking traction.

4. Measure the distance the frame rails are off the floor when you are sitting on the bike. Did you gain clearance? You can adjust the shock and fork preload, and adjust the height of the forks in the triple clamps to get the frame rails as close to level as possible.

5. Work on the forks. Put a plastic tie on them to see how much travel you use. If they are still stock, they are probably too soft. You can add up to 2 oz of fork oil to reduce bottoming, or add air valves. The Works Dual Rate fork springs are far better because you can adjust the crossover point between the initial low and final high rates. See my signature for details. DO NOT simply change to stiffer fork oil. That is the wrong direction because it slows movement of the forks too much.

6. Assuming the shock set up is correct, which basically means a smooth ride without bottoming out and not over damped, go back to the number 4 and set the chassis pitch to whatever position you want to give it the feel you want.

Get all this right, and then move onto the 1250 conversion. Contact Whittlebeast about his single disc brake upgrade. He changed the caliper and master cylinder.

On a stock bike, 1/2 turn on the adjusters can make the difference between binding and not binding. Make sure you also get a good alignment.The dealer tech adjusted the chain, but that's good advice to check it

2. Get a Superbrace fork brace.Got it. Pic taken before install

3. Experiment with different tire pressures. Too high can reduce the contact patch and make it unstable, and loose braking traction, too low and the rim can bottom out against square edge bumps. I like pressures on the low side so I get maximum braking traction.I have & 38/40 seems OK.

4. Measure the distance the frame rails are off the floor when you are sitting on the bike. Did you gain clearance? You can adjust the shock and fork preload, and adjust the height of the forks in the triple clamps to get the frame rails as close to level as possible.I did gain clearance, I got about 5-51/2". I adjusted my preload according to shock manufacturer rate, then softened them to take some twist off swing arm. But I'm going back to that setting, cause now I get frame unstability from gusty cross winds

5. Work on the forks. Put a plastic tie on them to see how much travel you use. If they are still stock, they are probably too soft. You can add up to 2 oz of fork oil to reduce bottoming, or add air valves. The Works Dual Rate fork springs are far better because you can adjust the crossover point between the initial low and final high rates. I received progressive forks and the tech dissuaded me from putting them on so I sent them backSee my signature for details. DO NOT simply change to stiffer fork oil. That is the wrong direction because it slows movement of the forks too much. So far the set has tightened everything up. I figure the OEM front forks are OK now since its a one up road bike.

6. Assuming the shock set up is correct, which basically means a smooth ride without bottoming out and not over damped, go back to the number 4 that I gotta doand set the chassis pitch to whatever position you want to give it the feel you want.

Get all this right, and then move onto the 1250 conversion.Nah. I'm an old dog. I bought this bike to slo down for safety reasons. My current touring bike is a 95HP BMW R1150RS. I go for hours north & south of a buck and I just have to stop it. I wanted the HD to go 80-90 safely and it's not there yet. Contact Whittlebeast about his single disc brake upgrade. He changed the caliper and master cylinder.
Oh BTW, I'm an unrepentant squid.
