BPA Racing Chain Slack Adjustment Tool | A Must Have Motorcycle Tool

[@gerrycout7845]

A chain develops tight spots as it wears. You would have to put this tool at many different location around the full length of the chain to find the tightest spot and then adjust from there. Faster to check by hand.

[@k31chris]

Can you show how to calibrate it with out a allready perfectly adjusted chain. It takes me 30 seconds to check chain with a tape measure and that includes the 25 seconds to find the tape measure. Does BPA stand for Bloody Pointless Apparatus

[@k31chris]

On an allready ok chain though. If your chain is too slack or tight to start with how do you set the tool.?

[@mikeinnh9179]

@@k31chris You have to adjust your chain the old fashioned way, then calibrate the BPA tool.

hey Cali Moto, just wanted to thank you for the videos. I recently got a 2021 V2, and let me tell you, no one has videos on how to work on them, and very little info on specs, such as chain slack, and how to measure it. So a big shout out from the V2 community, as I'm sure they have watched some of your videos, Thank you very much!

[@CaliMotoTV]

Glad to hear you found this helpful. More V2 videos coming soon!

[@davidstatham7760]

What a brilliant tool. Thanks for the demonstration 👍. I need one for sure 👌👍.

Any experienced motorcyclist or racer should easily be able to feel for proper chain slack juat by spinning the wheel by hand and moving the chain in various places. It's pretty easy to spot a lose chain vs one that is good, and it's not an exact science. I can't imagine a rider ir even racer needing to have a chain that precisely adjusted. Even the service manuals give a good amount of variation like .5 to 1" of freeplay. Also, the slack should be checked at several places because chains don't wear evenly, so you'd have to move this tool around the chain to make sure you have checked everywhere, whereas simply spinning the wheel and feeling for the correct slack is so much easier.

[@Mark-Dibble]

Maybe you could mark the chain slack with a sharpie for other bikes and make the line marks permanent with a hack saw on the outer nut. I hope that made sense lol. Great tool, I’ll probably end up with one.

[@stephendavis474]

Conveniently forgets to mention if you have more than one bike It would be useless as it can only retain one adjustment at a time meaning you have to adjust the chain on each bike first to the correct specs before you can calibrate the tool to THAT ONE bike which means if it's calibrated for bike #1 it needs to be recalibrated again for bike #2 unless there's a way to accurately mark the tool for a second bike

[@sergionuno]

Thanks for the info, that's what i wanted to know, because i also have several bikes.

[@cranfktubner7677]

Pretty cool. I saw this tool and wondered how it worked 🤔now i know ! thx you 👍

[@sergionuno]

My doubt here is, What if you have more than one bike? Does that fit all other diferent bikes i have? Or eatch bike has a different calibration?

[@infinityphotorob]

I need this for my 1190. Will this thing work good for bikes with a lot of slack?

[@javierr1blue]

I watched your video went to Amazon and bought one thanks !! lol

[@jbawden]

My $3 analog metric ruler works fine...this is a tool searching for a problem to solve.

[@merakrut]

When the Counter shaft, Swingarm bolt and Rear axel are aligned that is the chain's tightest point. Adjust the chain to be tight at that point, then make a piece of wood that fits between the chain and swingarm when the motorcycle has the suspension fully extended. I place the wood piece at the mid distance on the chain. On my dirtbike I have two different sizes on the wood pieces, one 5mm taller for when I'm riding in sand to make room for sand on the sprockets.

[@justinwyatt4324]

This seems like a tool that most people in my group would ask why, If you don't know how to adjust a chain for proper tension after 44 years of riding then one of two things you've got really good friends or to much money to pay your local shop to do the work! I am a tool junkie but I think I will wait on this one. great video thou!! keep putting in the work!!!

[@CaliMotoTV]

It's really meant for someone who's gotta adjust their chain frequently and quickly, iE a racer.

Guess you don’t like evolution in technology lol, better ride your carbureted, drum brakes front and rear then lol

[@stang1970]

@@sicks6six lol, good springs hold up well over the years. I have several guns that are over 50 yrs old that the springs are still fine in. And how hard would it be to double check it every few months anyway??

[@xkidROBOTx]

Unpopular opinion: anyone who say this tool isn’t faster after the initial calibration have been doing their chain adjustments wrong for years. This tool is aimed at the riders who ride fast, hard, and frequently need to check and adjust their chain.

[@Wabbit1961]

Chain slack does not change whether the wheel is up or on the ground. Single-sided swingarm bikes are all easy to adjust. Honda Interceptor has the same ratchet style gear, or at least my 2006 did.

[@CaliMotoTV]

👍

[@JimV90]

Only problem with this is you still don't know if the original slack that you are calibrating the tool to is correct. All the tool does is keep the original calibration in spec. Still pretty nice to have to deal with chain stretch over time.

[@CaliMotoTV]

It's not really a problem since that's not the tools purpose. The tool is designed to help you adjust the slack back to what you want it at and is really intended for someone who frequently changes tires / gearing etc that require chain adjustment, primarily racers / track day enthusiasts.

[@JimV90]

@@CaliMotoTV I agree. My comment was based on your introductory remarks about not knowing how much slack a chain should have, and that this somehow solves that problem. Which it doesn't.

[@Mirrikat]

Don’t waste your money - it’s pure snake oil. I bought one a couple of years ago. Just got a new motorcycle and I thought this would be the bike I would use it for. I attempted to calibrate it following the BPA video tutorial and it doesn’t tighten. The aluminum bar that is threaded onto the “calibration” bolt just spins when you tighten the calibration bolt. Even if you could actually tighten it, then the unit wouldn’t pivot. If it is tight and can’t pivot how would it adjust to show you whether your chain is loose or tight? I feel like a fool for purchasing this thing.

[@MOTOUK1]

I use a chain monkey tool similar easier and cheaper. Both great tools thanks for sharing

[@stevied6286]

Or U could just use a ruler from the floor and make sure the up and down movement falls within a pre-determined range that you would need to know anyway in order to calibrate your chain tool?? Ruler = approx 30 pence/cents and a Sharpie mark on the swingarm to show the centre point between the sprockets where you need to measure ( with the chain at its tightest point! ) I'm not convinced this makes that 30 second check any simpler, but it does look nice 😂😂

[@japfourme381]

Great vid mate! I do have the chain monkey but I’m going to get one of these!!

[@Wabbit1961]

Motion Pro chain slack adjustment tool is what you need. Works on any motorcycle. You use it to check current slack and then to check after adjustment. This tool is only good once you set proper chain slack, and then only good on that motorcycle. So I have to buy one for each motorcycle I own? This is not a cheap tool! You may have paid for it with your own money but you push it like an info-mercial.

[@supresto8214]

Cool tool. Great videos as always Question: is there a rear stand that works on both the V2 and Streetfighter?

[@supresto8214]

@@CaliMotoTV thanks so much for getting back to me. Keep up the great videos.

[@TheLostGhostrider]

very interesting product, too bad that to have it in Italy, the shipping costs and customs taxes are too high

[@riggers7480]

The design appears flawed: the spring is quite strong, so requires force to extend it to engage the aft lug over the chain. That force can easily shift the big nut, screwing the calibration, unless the Torx screw is done up tight.. However, tightening the Torx screw sufficiently to retain the setting also locks up the device so that doesn't articulate, but locks solid. Unfortunately, I've bought two Slack Adjuster Tools to cover my two quite different bikes, but from my experience, I can't rely on the tool keeping an accurate setting, so I'll have to find another way. It's particularly disappointing, because the tool has the look and feel of a quality product.

Thank You...

[@flybyguy1450]

So in order to calibrate the tool you need to set the slack perfectly in advance? Seems pretty useless to anyone who isn't sure how much slack they should have in the first place...

[@kingtee94]

I had the same thought.

[@ethanmax3168]

Exactly what I thought. So you will mirror a wrong slack if you had it wrong to start with.

[@AndrewMccravy]

just take it with you to your local shop next time you need to adjust your chain. its get set to spec and at least my shop, will let me be back with them. perfect time to calibrate the tool so next time you're good to go on your own.

[@harry101fly2]

If someone doesn’t know how to look in their owners manual and read instructions how to set their chain slack, or even have an idea how to do it, they probably shouldn’t even have a bike

[@nooneshero9819]

I’d rather a motion pro slack it’s 1/4 of the price and can be used on many bikes. Plus it only takes a few seconds longer then this would.

Aren't you supposed to check for chain slack at the tightest part of the chain? That should be done first then adjusted using this tool.

@@CaliMotoTV thanks for the reply. I guess having been adjusting chains for nearly 40 years, I can do it very quickly due to experience. It's the wheel alignment that takes longer but perhaps that's not an issue on more modern bikes? My newest bike is 19 years old.

That's me too, on the gimmick product. It is not possible to correctly set the slack with the bike up on the stand, unless the rider is on the bike wearing full race gear. Then it would be accurate, until chain and sprocket wear takes place, then what?

A step in the right direction, only if it came pre-calibrated it would be perfect

It would be good for you to understand the difference between an "allen" (which this fastener is NOT) and a Torx, which this IS. Credibility at stake here, sir.
