I wouldn't waste time or money  for a 120RPM drop  at 80 and less at 60.   That not going to even be noticeable.     
With my 240 tire  actually at 60 mph its dropping me 267 rpm and at 80 its dropping me 356 rpm.   I cant say weather ill notice it yet because their just sittin on my work bench.
Where are you getting 120 rpm at 80 at ?? :shrug:


You posted  this   So I was using your numbers.   

Normal Rpm with stock tire according to the chart is 65mph -2632 rpm and 80 mph is  3240 rpm
If you are running the 240 tire the you will shave  97 rpm off 65mph to 2535 and at 80mph shave off 120 rpm will be 3120 rpm

Sorry about that . Ive been kinda busy lately . My post count has went down some. On the front sprocket . I really wouldnt know i didnt do that mod on the front just the rear . I kept the stock front pullye. The rear. Most of your Harley sprockets are bolted right . Just dont get the one with recessed holes.
A recessed hole is like a hole . And a hole a bit wider around that hole tht only goes about half way.    http://www.sharpteksupply.com/servlet/the-432/Foot-1-fdsh-2H-Recessed-Hole/Detail       their is a picture. Pictures are lot better than me talkiin ;D .     
Aight . On the center hole . My sprocket needed the hole bored . Thats no problem for a machine shop.
On the pulley you looked at  http://www.ebay.com/itm/BIG-DOG-POLISHED-PULLEY-TEFLON-COATED-61-TOOTH-1-1-8-BELT-2008-UP-RIDGEBACK-/140898209489?_trksid=p2047675.m1850&_trkparms=aid%3D222001%26algo%3DSIC.CURRENT%26ao%3D1%26asc%3D11%26meid%3D4263218471882380456%26pid%3D100011%26prg%3D1005%26rk%3D1%26sd%3D121023801226%26#ht_196wt_1399 Dont get it . It wont work. At least it wouldnt for me . The machine shop said they couldnt do it. The recessed holes arent wide enough for the self lockin nut to go on. It needed to be wider . Way they told me it Their machine couldnt do it.
The spacer. You shouldnt need one . But dont quote me on it . You never know you may. The belt is the easy part.  Wichever one you choose.  Paladin and me think that the gates is the better belt.

Thank you very much Sweet Tooth,

I realy appreciate your help. As I'm not an english native speaker, sometimes I do not understand terms.

Understood what recessed holes means.

The belt I can order directly from ebay, no problem.

If your pulley is OK, how can I get the same pulley  :) ? did you bought it from ebay ? if so, can you please send to me the link ?

Or this one : http://www.ebay.com/itm/Sportster-Rear-Pulley-HD-Black-1-1-8-x-61-Tooth-Polished-Outer-Ring-40246-91-/230899061726?pt=Motorcycles_Parts_Accessories&hash=item35c2a813de&vxp=mtr#ht_674wt_1399

A Big Thank you
Marcel

Just receiced my 61T, 1 1/8 pulley, bought it from ebay for 50$ + 50$ transport = 100$ total.
It's coming from a 2003 Harley Sportster.

But I'm not very happy about it's condition, few teeth has some damages. Looks that bike had over 100.000 miles on it.  Thinking to use it or not ..... :(
The new belt (130T, 1 1/8) will arrive in few days and I'm thinking that the worn pulley will damage also the belt ...

I would not use that pulley. From the pictures you posted, the damage looks cosmetic (flaking chrome), but judging from the overall condition of the pulley, I'd guess the pulley's teeth are pretty well worn. If you were to use this pulley, I think your belt life will be greatly reduced.

Yes,

Thanks for advice, I was thinking the same, but now I'm convinced. I will look for another one here, in Europe, less costs for transport. There is a saying : you meet everybody two times ...(hope will be valid only for the pulley :))

PS. just as info : Sportster pulley fits well to Raider stock hub. Just need 5 spacers, little bit to enlarge the fixing holes and use the stock fixing screws.
