I will soon need to replace my sprockets and chain, I’m thinking over the life of a drive belt, would it be more effective to go to belt drive for long-term cost and maintenance time? How many miles has your belt drive lasted? What if any drawbacks have you experienced? Between adjusting, lubing the chain every 350 miles. It maybe more practical to go with the belt drive, even though the initial cost is quite high. What are your thoughts?

we only have one option, i want one bad but chose against it for a few reasons. one being the guy is virtually impossible to get a hold of, 2 he is not the most personable of people, and 3 when he is gone to get replacement parts means having a shop make the parts if they even can or will. i have been trying to get scootworks to do it, they were willing to a few months back but seems they have now changed there mind. i say we keep sending them a bunch of emials and see if we can get a 2nd cheaper option. so basically go for it if you have the money, many people love it, have not heard anyone complain who owns one.

Either that or you can snag a set of Sportster belt-drive pulleys off of EBay and have a reputable machine shop drill the rear to match your bikes rear sprocket mounting hole pattern. The front might be a tad dicey, but if you took both in to the machine shop, I'll betcha they would be able to make it work. Then all ytou'd have to do is order the right length belt. Well, that and making sure you have the side clearance....

Hey DWIGHT!? Where are you? This company is in Paramount, CA, just off the 105. You're retired, stop by with your bike and get them to measure up what they need to get a setup made up for the rest of us!

What do you guys mean, "make yourself useful...for once"???  Why I'll have you guys know that without my sardonic and witty repartee 'round here, this place would be but a shell of what it has become!!!  Now, besides all that, I might just be able to take a ride to that garden spot, also known as Paramount CA, within a couple of days and work somethin' out for all you gentlemen. (MAN!!! I'm tellin' ya...these people 'round here just aren't satisfied unless you give 'em some of your blood, sweat and/or tears!)

TooCool,
That is Too Cool! Thanks for that link. Exactly what I've been looking for. I've got a front pulley heading my way at this time. Gonna see what it'll take to match it up with My Speedy's front sprocket mounting point.

Oh, come on, it's not like its close to COMPTON or anyplace like that! Oh wait, it is. Well, then you should refer to the post about concealed carrying on your bike. You should go early, the crackheads sleep til noon. Just ride very fast, chances are they will not see you.

So, can one of you beltdrive owners let us know, how many teeth your pully's have and the thicknesses. Maybe we can figure something out.

The rear pulley on the QPD kit has 59 teeth. The front has 24. The pulley itself is 1.4375" wide.

I don't really have a problem going to Paramount(I was just kiddin' 'bout the "garden spot" thing), but I'll draw the line at goin' to Alhambra for any of youse guys, cuz ya know, that's where a certain record producer/murderer, who threw enough money at the court system to drag his trial on for 5 months and subsequently confuse two yo-yos out of 12 and have them believe he was innocent, presently resides, ya know!!! But I digress. Well ANYWAY...Maybe I've missed something here, but my question is, folks: What's wrong with purchasing the above gentleman's(Brent) fine belt-system here. Is it that his supplier is not making the pullies(or is this pullys???) for our machines anymore? I'll be happy to do the legwork here gentlemen, but I'm not sure why this is needed???!!!

Dwight,
Maybe you should talk to Brent in a PM and work something out here. The QPD source may be an issue for Brent as well as folks that try and buy direct.

Personally, I'll always try and make whatever I'm looking for first. If I fail, then I'll buy the item retail. There is a huge amount of satisfaction that I receive by fabricating something up from scratch (or as scratch as I can get). Huge sense of accomplishment there.

I have a 32 tooth front heading my way. Guess I'll need to get a 72 tooth rear to have any chance of keeping low end capability. Should increase my top end though.
I sent All American a message to see what they charge on their 72 tooth pulley blank. I'll post when they reply.

I'll be very interested to see if a 32 tooth pulley works up front. I think you'll find that there isn't near enough room to support a pulley that big. But I ain't never tried it...

If the diameter of the 32 tooth is too large I can always find a smaller one. I'm only in the 32 for $23.00. It's a take off from a Revtech Tranny I found on E-Bay. If it's 'close' I might be able to work with it. You have the diameter of the QPD front?

Sorry guys. I just called their shop and the only pullies they have come in 65 and 70 tooth, and are 1 1/2" in width, or a 72 tooth in 1 3/8" in width.

1 3/8" might just be the ticket. Not as wide as the 1.5, and the front sprocket on the way can be cut down on width. Nothing a well-utilized band saw can't handle.
Dwight, don't be such a negative Nancy :-)

Hey Mike! Whaddaya mean "Negative Nancy". I'll bet cha even Walker, Texas Ranger couldn't turn a 72 tooth pully into a 59, Dude!!! How are you gonna do it???

Brent,
Does that 7/100 of an inch in width really make that much of a difference in anything. In other words...Was there a reason you gave such an exact dimension of 1.4375"?

59? Where does 59 come into play?
I'm just saying that the 72 tooth, 1 3/8" pulley could be the ticket here. The front sprocket I bought is wider than 1 3/8" and can be cut down. Thinkin outside the box over here.

Right here, Mike.... Quote:
The rear pulley on the QPD kit has 59 teeth. The front has 24. The pulley itself is 1.4375" wide.
-brent
I'm thinkin' that if you'd go larger on the rear pully, in order to keep a ratio close to the 16/17/18 teeth countershaft chain spocket setup, you'd have to go a lot larger on the front pully also, and thus it could be too large to fit inside the sprocket cover without rubbing on it.
Am I wrong?

Gotcha on the 59! Thanks for the refresher.
The QPD 59 Rear/24 front setup has a 2.46:1 ratio.
My anticipated 72 rear/32 front ratio is 2.25:1. So, unless I'm wrong (highly possible), on the QPD set up, the front sprocket will rotate 2.46 times for every rotation of the back wheel. With the 72/32 setup, the front sprocket will rotate 2.25 times for every one rotation of the back wheel. This will take more torque to turn the wheel, but not by much, over the QPD. Should also increase my top end/cruising capability.
Make sense???? Really, I need someone to check my logic.

Oh, and I'll wait to see what the diameter/width of the 32 tooth front sprocket is before I try to wrap my grey-matter around that one. I looked at the cover today at lunch and there seems to be a good amount of clearance there. If it will be enough remains to be seen. A Sprocket cover spacer might be needed....

Okay. I received the front pulley today (32 tooth) and MAN that thing is huge. It's 2 inches wide by 5.5 inches across. Weighs 6.5 pounds. Haven't had the opportunity to take it to the Speedy, but I'm thinking -
1. Too Large. Probably need to find a 24 tooth or there-abouts.
2. Too Heavy. Need an aluminum piece. Even if I could modify the piece or sprocket cover to fit, the weight of the thing would be a HUGE detractor.
Luckily I'm only in it for approx. $25 US. Probably put it back on E-Bay.
Now looking for a lighter aluminum unit. Wish me luck.

Okay, I'm thinking that the real problem with converting our bikes to belt-drive is finding a suitable front pulley. Oh, and of course, making sure it matches our shaft configuration. I think a 24 - 26 tooth count pulley will be the one to work, as long as it's 1.25 inches in width. Now I'm just spitballing here, so please any of you more knowledgeable folks feel very free to chime in.

Mike,
Yep! At 6.5lbs I'd say the steel piece would be quite a bit of weight to start spinning around and you'd be wise to find an aluminum piece that's no larger than that 24 tooth size which you mentioned instead.
It too bad Brent's source seems to have dried up here, because most of those who bought that setup(like Friar John for instance) seem to like it a whole lot.
