124" build...I'll let the cat out of the bag

[No Cents]

still running a belt for final drive...with a 30 tooth Andrews tranny gear and a 70 tooth rear pulley.
I've kicked the idea around for a chain drive for some time...but the belt has held up to my abuse so far.  knock on wood
I went as far as to buy an extra belt for back up...it's still in the box.

chain here, Ray

[No Cents]

the belt is for spanking

Sounds to me, you need to put it on the track. We don't race dynos and talk is cheap.

Chains can be too... 

[No Cents]

I do know a lot of people are set on chains being the best option. I had bought the extra belt back 3-4 years ago when I did a 103 Stage 4 build to have a back up if this one went south. I have always been a little leary about the belt...and do check it quit often. It's still hanging in there and shows no sign of giving up so far.
Now next week, with the way my luck has been running...I'll probably have it shread on me.

I don't think the belt is going to give you any signs, just leave you stranded. If it ever hooks up that is. All it takes is one wrong move. Front end comes up in first, you grab second as the front end is dropping so it can't pull the front end back up and the tire hooks up, something's gotta give. It's hard to avoid certain situations on a fast bike when the gears come quick. This one happens to me once in a while and I cringe every time waiting to lose the mainshaft. Seeing as you have a spare, you could hope the belt acts as a fuse. That's why we used to run stock head gaskets when tuning boosted mustangs. I was leary about going chain but couldn't be happier. I'm using a sidewinder chain and I've only adjusted it once in 3k miles and it gets abused. The only thing I'm sure you'll hate is it's DIRTY. Lube is all over my rear wheel, fender and kickstand. But you could probably find a chain wax or something that clings better. I'll never go back though. Not sure how your 6 speed shifts but a lot of people complain about them. After the baker door, manual primary adjuster and chain drive this thing is smooooth.

The belt has been proven to be stronger in lab testing than a chain but it cant with stand side shear most HD frames promote under aggressive load and the chain option does.

someday...I'll convert to a chain final drive. I might have to put that at the top of the list for my winter project. I have 3 Guyz and Drago's in my favorites saved on the computer for a couple of years now as possible vendors that sell the conversion. They are the only 2 I have found so far that offer a kit for a 2008 FLHX.
Are there any other companies selling them?

[Deye76]

  You never know, George Bryce ran a 145" 200hp RoadKing at the track, stock belt, wheelied 1st and 2nd, did fine. 

[2006FXDCI]

Zippers has kits made up for chain drive Ray

[No Cents]

 
thanks for the heads up...I just checked it out on Zipper's web site. They are priced cheaper than Drago's and 3 Guyz Inc. I do like that Zipper's offered more gear ratio options. I'll be calling them 1st thing Monday and see what they have to say. They offered a sealed O ring chain and the heavy duty drag racing chain...that apparently isn't an O ring chain. How strong is the O ring chain...I like not having the oily mess all over everything that a chain that you have to lube creates?
I'm currently running a 3.15 with the belt. If I go with the 24 tranny and a 55 pulley option that they offer...it will put me @ 3.10.

Got over 80,000 on my original belt. It has seen a few wheelies .
I need new clutch plates real bad though .

[strokerjlk]

Sounds to me, you need to put it on the track. We don't race dynos and talk is cheap.

We who ?
Put up or shut up

[hrdtail78]

We is anybody.  He is saying 13's, you are saying high 10's.  Going to the track is fun and a learning curve.  No Cents has put a lot of effort into this bike and would enjoy a track day with it.  Several.  He will hit the 13 mark and start to better that time and getting into the 10 second club is something he will enjoy and remember.

Nice build and good luck.

Wasn't posting to you and I don't.  The stuff between me and you is in your head and I don't worry about it.  Tapatalk doesn't have the ignore function.  So, regrettably.  I see your post.  let it go, and have a nice day.

[2006FXDCI]

Ray, I would think the O ring chain would be plenty strong enough for your build and no mess with oiling it. Should be able to use chain wax on it. I believe both chains are a 530 series chain from Zippers

[Jaycee1964]

Stick with your belt and save your $$$.  More than strong enough, less noise and less maint.  If it ain't broke don't look for a break.

the 13.0 was me joking around...I'd launch her and let 'er chew...without a doubt. I wouldn't be scared to twist on it for everything it's got. My problem would be getting the back tire to hook up fast enough. It just wants to spin the tire thru the first 3 gears now...and not even be on the rev limiter doing it. I would have to practice, practice, practice launching it to find out where it wants to be, to be able to keep it hooked up.
Jim say's high 10's-11.5...it might do it...it has that cocked and loaded feeling everywhere...but   
I was bored yesterday after I got home from a couple hour ride...so I played with the 5" Trapp can a little so I could get it out of my system and finally lay it to rest.
I tried it first with 15 disc's and an open end cap. The bike didn't like that at all...it idled terrible and didn't have near the throttle response at all like with the Zilla muffler. I then tried 8 disc's...same results. I decided to take the baffle out and removed the packing off it and installed it back in with the open end cap with no disc's. The bike seemed to idle way better, and with it just sitting in the barn...the throttle response was much better than the first two attempts. It was late so I decided to wait until this morning to take it for a ride and she if she stumbled any. The no packing and the open end cap was at least 30% quieter at idle vs the Zilla can and didn't sound too bad.
I rode it today and it didn't stumble anywhere..."BUT"...the bike does not pull anywhere near as hard in the 2-3K range like it does with the Zilla can. End of experiment. The Zilla's can is back on and I rode it again...no comparison between the two...throttle response is back and it pulls like a Catepillar motor again.
  End results...the Zilla muffler stays on!

I love the belt and wish it had held on the fatboy.  Two things that save them on the street is lack of traction and clutch slip. Once the bandit went in the bike and the clutch was rock solid the old stock belt broke. After trying a new HD belt and having it brake on the first launch on traction compound with 15 lbs of air in the back tire and then breaking the "better" aftermarket belt at track day, the Softail got a nice big o-ring chain, it also lets you mess with the rear gearing easier.  I have seen more than a couple 5 speed bikes at Vic's shop that when the belt breaks it lashes the gears and takes out the transmission. I have not seen it with a six speed so maybe they can take the abuse. All that said you will have the time of your life running that monster down the track and the only drawback is you can become addicted with one use of the drug.

No truer words spoken .
I am at the point of needing new clutch disks . Losing mph now .
If I get it hooking real good it's probably gonna take a belt out . Everyone that keeps at it on the track eventually goes chain .
It's a disease . And I ain't ready to submit to a chain . She is # 4 in points so I get sucked in .
When honestly I just need to leave it home .
Anyone got a slightly used set of pro clutch disks ? 
Ray
Your bike
It will run a 11:50 no problem .
How well it pulls 5th gear through the traps ,is what we need to see.
It will run an 11 against the limiter in 4th ...

  Although my S&S 124 doesn't put out like yours, its still 126.2hp/134torque. I converted to a 530 EK Chain when I installed the engine upon reco from some outstanding engine builders, kendall Johnson being one.
I have never regretted this conversion, with 46000klms on it now, and untold, 1st,2nd and 3rd launches, it has barely stretched. I use Maxima chain wax, it stays on if sone properly, and once every 4-5000klms is enough! I have bent the 3/4" rear axle tho! fwiw   Buffalo.

My race bike takes a new axle everytime the wheel comes off .

Jim, I have a complete Pro Clutch, with a gold and a silver spring.
Came out of my 07'. Low mileage, never beaten on.
I stepped up to a Bandit, when I went with the 124 build.
I could use a few bucks, to help pay for the new Corbin I ordered.
