1800 rpm ??!! In 6th gear??!!
How do I post the little smiley face guy banging his head against the brick wall?[sm=headbang.gif]

Never mind . . . I found it !!!!

 

You left out the KEY element in quoting me....."Sarcasm not pointed toward you, alexcue. " Key word there being....and I quote myself again....."SARCASM."

Not that anyone gives a rats tutu, but at this point in what has become a senseless forum discussion I'm calling it a day with this one. [sm=smarty.gif][sm=smarty.gif][sm=smarty.gif][sm=smarty.gif][sm=smarty.gif]

 

I may have accidentally stumbled on a solution to the gear chatter the new six speeds have a say speeds less than 65 mph in sixth. Let's me explain, everything came together like a perfect storm.

My new 07 FLHR is my second Road King and both of them had the high speed wobble that you have probably seen discussed on numerous Touring posts. Well on my new bike I decided to purchase and install a True Track.As one can see from the attached picture the True-Track attached to the bottom of the transmission pan. Well when I torqued the transmission bolts up, when I installed the True-Track, I did not quite torque them enough. After the True-Track installation I could smell a small amount of oil burning every time I rode the bike. After a couple of weeks I got back under the bike and torqued the transmission bolts again. At this point I thought it would be a good idea to check the transmission fluid too. I was not surprised to find the transmission fluid down about a quarter quart. The problem was that I ended up adding about half a quart, putting me about a quarter quart over full.

Well I know Harley always warns not to overfill the fluids, and typically I follow their directions. However, in this case I decided that I was not going to drain a quarter quart of transmission oil with the 1,000 miles service coming up in a week or two. Well, I took the bike for about 150 mile ride today and guess what, sixth gear didn't chatter any more. It pulled no problem (nice and quiet) from 55 mph, in fact it pulled no problem from 50 mph. Fifth still chattered a little at low rpm's but it was significantly improved too.

I am pretty in tune with my cars and motorcycle and I know sixth is much quieter now at low rpms. I am wondering if Harley made some tradeoffs and went with a little less trans fluid, or perhaps they made the dip sticks wrong. I am not saying everyone should go out and overfill their transmission fluid, but perhaps other 07 Touring riders with mechanical savvy could verify this result. If in fact the result is repeatable then perhaps were on to something. If I am wrong one could always drain out the excess.

This is accurate in my experience, although I think I'd limit the last example to 1800 while maintaining speed. Coasting (decelerating) down to idle won't hurt anything. The problem with the TC96 was the clattering drivetrain that made it sound like the engine was lugging. My old Evo RK could run all day in 5th at 1800, although I would not accelerate or try to climb a hill in that state. Now that I've installed IDS my '07 miraculously feels like the Evo, which is a big plus. My 4-cyl. car with square engine can run effortlessly down to 1800 RPM, so I know an under-square twin with a 4.38" stroke can do it without stress or damage.

 

Did you install the same type and viscosity of oil when you added? I can't explain this, but there may be unfavorable side-effects to overfilling the tranny. First, it may barf through the overflow tube, and if it does you'll get sick of the gear-oil smell all day while riding. This would occur on my old Evos, but I don't know if the 6-speeds would react in the same way. Second, it may cause the oil to aerate since it'll probably make contact with more moving parts if the level is higher. I'm speculating here, as I haven't done it on this bike. My old Evos didn't like more than 22 oz. installed, even though the spec was 20-24 oz.

 

With the quarter quart overfill I am currently running in the trans, pulling from 1,800 rpm's is no problemat all.

 

Since I changedthe AF mixture... I can lug sixth down below 40 mph. If I ease on the throttle I can pick up speed without down shifting. That's riding two-up. When I first got my '07 .. at 62 mph in 6thit would ping, clatter and knock. I still have my lowers on and am very pleased with the overall performance of my bike. If needed I can get my son to video my speed and rpm, then post it.

 

Bingo

 

I put on the IDS and my EGC is like a new bike. It's smooth and quiet. I get no more driveline whiplash. I'm happy with the mod.

What is puzzling to me is the fact that it only will fit back to the 07.
Why did Harley hollow out the rear hub on the 07? Could it be they were meant to have the IDS but it was not ready in time?

 

I did notice the rear wheel is differnt from my '06.
