Oh and by the way... If changing the cha? You do not need to remove the rear tire. If you buy the original 420 chain, remove the master link, take chain off, put new chain on... Done!!!!
Put an o ring 420 on my monkey when I got it. Plus 14 tooth countershaft sprocket, have 4500 miles on it with no stretch at all. No power loss that I can feel at all.
I thought about doing that I had even bought the 420 chain. I was at a big motorcycle event and somebody there was showing me what they had done to eliminate Chain stretch. I started looking around the Internet and it seem like the thing to do.
@@officialwaybackwhen I have had it up to 64 mph on a flat road for a long stretch. Wore the back tire out, I like the V rubber, front still good. The rear tire is backordered since July, hope it gets here soon.
it didn't stretch because of the size, it stretched because of the crap chain they use from the factory. I run 420 chain on 40+ hp v twins and never have any stretch problems, but I use good D.I.D chain. if the mod makes you feel better though, it was worth it.
I’m happy with the mod however I will be dropping two teeth on the rear sprocket. Going down one in the front was the right decision going up in back was not.
In the UK the 2019 Monkey came from factory with a DID 420D (solid bush, non o-ring) chain. I've done 50,000+ miles on mine and lost count of the number of chains I've been through. Tried different DID 420s (black, gold and black), JT 420s (regular, gold and black, silver and black), and different starting tensions. Zero difference. I figure it's mostly a combination of soft stock suspension and lack of chain sealing combined with the propensity for the chain to pick up a lot of crap on our damp UK roads given it's so low to the ground. I like the look of the stock springs with the little chrome top sleeve so am gonna jig them up with the Chimera Eng spacers, I think, and see how that affects chain wear before doing a 428 o-ring upgrade.
@@humblegrumble1615 The monkeys did NOT come with DID chain lol they use the cheapest whatever they can find china chain, it stretches badly. I switched mine to niche x ring chain and haven't had a problem. i live in rural se ky and I promise our roads are worse then anything in the UK. why on earth would you go to 428 chain? makes zero sense. smh
You SHOULD use a torque wrench. To say tighten something up as hard as you can is ridiculous. Everything has a stress or breaking point. If you over torque, you'll stretch and weaken the bolts and studs, or start to strip threads. Also, never ever rely on swingarm and chain adjuster markings as being accurate for chain tension, they very rarely are. Also, never use threadlock on self locking nuts, the two are incompatible.

Not if your changing sprockets
@@officialwaybackwhen yes sah.

I installed a DID420V oring about 4,500 miles ago. Only had to adjust it twice since. No notable chain drag either.
I found the sweet spot is a 14 front and 37 rear. Way more torque. Speedo will be off. Needs a healer.
my atv has a 420 and my buddy had a new 428 chain can i use it with out changing sprokets
No
Why would you put the bike on a milk crate and under the exhaust????
Not a milk crate that was an ammo can, Worked perfect.
How’s the chain holding up? I’ve ordered my new chain.
Perfect
Still tight??
Heads up your speedo is probably off a ways from the gear change

@@officialwaybackwhen yea gearin a bike is pretty much different for almost every person but when you find that sweet spot, it sure makes them nicer.

@@billwilliamson9842 Nope... the UK-spec Monkeys came with a DID 420D in 2019/20.
