Phase 3 of America..... Absolutely the best belt. Been running a 2 inch Phase 3 belt for 40 years now and it still hasn't broke.

I have 1988 softail with kicker and electric start I bought the primo dry belt clutch kit. Yes you do have to grind some material off the inner primary so the belt doesn't rub and I do not have the idler gear. I haven't needed the idler gear in 10 years works fine without it. Run a jockey shift on mine as well and love it been 15 years now.

15 years is a solid review, glad to hear it!

I agree with your points on the idler gear but, on the flipside, a idler gear would be easier to adjust than the transmission. Even with a adjustable trans plate. Just something worth mentioning.

@greasesgarage

7 ай бұрын

The thing about the idler gear is that you can only mount it if you have an inner primary. And if you’ve got an inner primary you can’t adjust the trans via the adjustable trans plate anyways. So it’s an option for closed primary riders only. That being said, idler gear is only available for 11MM belts so if you’re going with an 8MM it won’t be an option.

I don't remember where I bought the trans shaft support bracket(probably JP crap), but I had to shape fabricated spacers to align the clutch basket outward to the motor pulley. Being my first Harley, I spent a lot of frustrated time trying to figure out what could be wrong with my machine, the instructions didn't illustrate an open primary application similar to mine, but eventually I decided to fab the shims and go forward. There's possibly different trans shaft bracket dimensions?? But anyway, I still kick n ride that little bobber beast for fun.

Happy to hear that! As for your current setup, no weep holes to plug. Unlike the sportster, the big twin has 3 separate oils…engine, trans and primary. So when you remove the inner and outer primary it’s just one less thing you need to fill, it’s great. You’ll still have your engine oil and trans oil to change but 2 is better than 3. Especially on those old shovels which tended to have leaky primaries

@greasesgarage You already know the key to long belt life, I'm sure. Keep proper tension and keep it clean. It's amazing how long it will last. The same goes for the chain and sprockets, I always preferred a quality O-ring chain. My last one was a Drag Specialties, and it's held up well, only 1.5 years ago, and still appears to be fine as well as the sprockets, no uneven wear at all. I do have my crankcase vent hose routed over the chain, though, and the fine mist keeps everything from corroding. But it also does collect dust and road grime. A WD-40 wash takes care of that, though.

@@greasesgarage It got pretty hot. I didn't run it long enough as a closed primary to find out if it would be a problem though. However, I did see it as a potential problem for longevity. It's a known fact that the road life of a belt doesn't come close to the road life of a chain in an oil bath closed primary. And dry clutches don't get the same cooling as wet clutches. So I went with open belt for functional reasons, and by default went with footclutch, jockey shift, and kickstart.

Regardless, seems great minds think alike (or was it by pure dumb luck) I seemed to have gone through pretty much the same questing exercise that you offer in this video. Still need to do the install since I'm still sorting out the install instructions. I'm used to the shop manual approach and what came with the kit is a bit lacking imho. I do have a question if you (or anyone else) is inclined to answer: My 92 FLHTP is a police touring bike (similar to a 92 FLHTC) and as best as I can tell needs to have the inner primary installed as part of mounting the engine & tranny in the original swing arm frame. Is there a solution/work around for going full open belt primary? Cheers Sammy Getty ps. I'm not building a chopper (or a bobber) just trying to keep the ole scooter as my daily ride without drinking the Motor Company's cool-aid.

Thank you 🙏🏼 good to know

@greasesgarage Thanks for the video. I appreciate it. Im currently building a 47U with 80ci barrels, 4 speed late Panhead early Shovelhead transmission (case #34703-65) on a 1948 wishbone frame with lowered seat post and I have a set of Karata 1.5" - 13.8 mm open belt drive pulleys. I do need to get the belt. Do you know if 13.8 and 14 mm are interchangable? I also need the clutch package. Any recommendations? Thanks in advanced!

Hey brotha, so for the belt I’d go straight to karata if they’re still in business and ask them which model belt you should run. Im not familiar with them personally. As for the clutch I’m running a standard Shovelhead 5 finger clutch hub with drag specialties discs. The discs aren’t specific to dry clutch you just need new plates that haven’t seen any oil

@@greasesgarage Cheers. Will try to get ahold of Karata. I do have a set of new clutch discs in the shop and an old and tired clutch set up. Will see if everything fits togheter before ordering a new one.

Pretty much it would be easier to just go with an open primary instead of closed.

In my opinion yes. No question. Easier to adjust your clutch, less bolts, less parts, no gaskets, no oil, no service interval, stator change takes half the time…what’s not to love?

What about the sportster evo not just the big twin??

That will need its own video as those are a lot less common and the kits do not follow the rules laid out in this video. I’ll need to see if those kits are even available these days. Evolution industries was the only one I remember hearing about and they were 2,500-3000 bucks. It’s hard on a sportster because you need to seal the transmission, it’s not a separate engine and trans like it is on the big twin so going open is a lot more costly.

@@greasesgarage Honestly, I'd say it's almost worth waiting and saving up for a used Softail, rather than trying to convert a Sportster to open primary.

@Lochlann13 100% agree. This open primary difficulty is mentioned in my “best first bike for a chopper” video as a con of the sportster. Kickstart conversion is expensive and open primary is even more expensive. We all tend to love both so sometimes it’s worth waiting it out for a big twin for that flexibility down the road

8mm can't use a tensioner (idler)... There is not enough meat on the back of the belt. 11mm only.... That's straight from BDL. You won't see any 8mm kits with an idler anyway... They also said that 8mm belts are more reliable.

This is excellent info thank you! Read up people, great stuff in the comments

just divide 61 by 41 and you get 1.487 so the engine will turn 1.487 times to the clutch drums 1 time. The number of teeth on the belt dont matter
