Even through this 120R went into my FXDX, I thought I would post the results here since the installs on this forum cost me the $8K to do this - so in a way you are to blame. Also, so you can compare this data point with the results already posted on this forum.

This install is a bit different from the others posted here. First, the bike is a 2000 FXDX Super Glide Sport. The Harley specifications state they only fit down to 2002 touring & dyna's (this model 120R is for years 2002-2005). The timing position sensor electronics were replaced in the bike to accept the newer post 2001 type engine. This was the biggest worry by the head mechanic. However, on the first try the 120R fired right up. No electrical issues. Also the bike is a 5-speed.

Second, the bike is not EFI. The carb was upgraded to the SE 51MM Super Bore CV and intake. An earlier thread someone asked if you can carburant the 120R - yes you can Course someone asked why would you... Well cause the bike isn't EFI and they don't want to pay the $$$ for an EFI upgrade. It wouldn't cheap so I figured I would keep the carburetor.

The 120R replaced a SE 95 CI built back in 2001. The same shop also built it and the mechanic that did it just retired Saturday, the day we fired the 120R up Also it is the first 120R the shop has done.

The 120R is stock - well as shipped. I didn't have the motor broke into to upgrade anything. I wanted the higher range cam because it’s a lighter bike with (cough, cough) the word "sport" in its name. The 95CI has S&S 585 cams, which is similar in range as the stock 120R cams.

I upgraded the clutch to the SE plates and an AIM variable pressure plate. The clutch pull is lighter than it was with the 95.

The exhaust is LSR-II's from RB Racing and yes its a bit loud!

Also I had it broken in on the dyno so its good to go. Now if it would only quit raining for a few days!

I attached the dyno’s for the 95 and the 120R.

 

nice...I bet that's going to be fun.

 

I think you'll need to start saving for a good supply of back tiresl

 

Should be a touch quicker than original, I suspect you will be upgrading the brakes shortly.

 

Funny you say that - yes thinking about it seriously. Maybe a dual 6 piston up front. Now sure about the back yet..

Wish I could go to a 180 in the rear, but maybe a 160 will fit.

 

I'd be curious if they could give you a sheet with SAE correction factor instead of STD correction factor, that would be the better comparison with your 95.

 

Very impressive torque curve and well done for showing that such a mod can be done. Should stir thoughts in a few bagger owners' minds!

On the 160 tyre front a Deuce and some later Dynas have a 4.5" x 17" wheel that takes a 160/70x17 tyre, worth considering. They can be had cheap secondhand on Ebay with a little patience. Any wider needs fender surgery!

 

Photo rider, sweet ride, I've benn getting together a 103" kit for my 2001 FXDXT and people think I'm crazy wow 120" must be a wild ride. I put a 160 on the back of mine and it fit fine, tight but no issues! check my album there is a pic from the rear it really fills the fender out

 

On your 2000 fxdx a 4.25 rim with a 140 is all you can stuff in there.

 

It has a 150 now. I thought that was stock size per the specs?
