Thanks for the info, my friend! I'm going to do that mod as soon as I get home from my business trip. I've been getting false neutrals on my 23' 250X. I thought it was me the whole time.

[@UpAllNight91]

Right on! This mod will surely improve that

[@Evo836]

Great little mod dude! No Bevis today but hear him out back.

[@UpAllNight91]

Thanks. The shop door was shut and AC on but he surely lets you know hes there lol.

[@mearnsmedia2859]

started watching ur channel for the fork service but i saw this and ima have to give this a crack ive been getting heaps of falses recently

[@UpAllNight91]

Yes sir, for sure if you been getting false neutrals surely do this mod. It will save your transmission!

[@shadrackcoaltrain6681]

I just did this from watching your video. 🤘 Excited to ride in the morning! Helpful hint, you can do it by only pulling the rear brake lever, center clutch cover, and clutch assembly. It’s easy to get to the lever that way still, and you don’t have to drain 20$ worth of engine ice, unhook the PV, pull the pipe, or risk messing up that big inner gasket. Only have to drain the gear oil that way.

[@UpAllNight91]

Hello. How did the ride go?

[@shadrackcoaltrain6681]

@@UpAllNight91 awesome! I was about to order an extended shifter, but after this mod I don’t think I need it anymore. 100% would recommend! They should come like this. It’s WAY better, especially for such a small change

[@UpAllNight91]

@@shadrackcoaltrain6681 Ahh thats great news! Glad this mod worked well for you!

[@Realryancurry]

Can you please do a video on using lock-tight, and your opinion on where and when? Smokers, strokers , clutch and ignition covers, shifter, internal engine, and perhaps how often you check bolts . I’m a woods and enduro guy for the most part but like your opinion. You keep making ‘em, I’ll keep watching ‘em

There's another mod that involves a bit of grinding on the shift drum.

[@UpAllNight91]

What does this mod do?

[@rztrzt]

@@UpAllNight91 Helps alleviate the false neutral issue. Can't remember the details but saw pictures over on thumpertalk in the yamaha 2 stroke forum.

[@rztrzt]

@@UpAllNight91 Apologies, it's not the shift drum but the SEGMENT P/N: 4EW-18185-00-00 One of the lobes has a depression and people grind a bit off the peaks on either side of the depression.

[@UpAllNight91]

@@rztrzt Ahh ok. Thats to keep it from catching the actual neutral so easy. But that won't help the false neutrals that happen between 2nd-3rd, 3rd-4th and 4th-5th... thats where this mod to the spring works

[@mathewquera1605]

Awesome mod I think I’m gonna do this now. Question tho I have a problem with my 4th gear. It stays engaged and shifts in and out of gear fine it just slips inconsistently in 4th gear. Thinking maybe the dogs are rounded off 😢 just wandering would this mod put more pressure on the gears staying in place. I know I need to pull it apart and replace what’s busted but the bike has low hours and otherwise runs perfectly so I didn’t wanna rebuild it just yet. Any advice?

[@UpAllNight91]

Hello. Sounds like 4th gear is already worn. If its slipping in 4th it will need to be torn apart and repaired. I would also check the shift drum while in there. usually when they wear to the point not holding power, it will need the gears replaced as well as the first fork and drum. Bummer. The shift detent mod may not help it hold in at this point but the mod will surely help keep this wear from happening again once its all repaired.

[@davidwatson8315]

What els causes false neutral other then the detent? I am having problems when down shifting on my 2014 yz250. Thanks

[@UpAllNight91]

Hello. other than the detent... dirty oil, broken part of transmission getting lodged in the shift drum, or a shift detent levers roller coming apart. I will say I had a 2015 YZ450 and I had to do the shift detent mod on that bike because I was catching false neutrals going up and downshifting. It surely did the trick and that bike needed it. Its done a little differently on that bike since the spring is different. I bent the tab of the spring to cause it to apply more overall spring pressure.

[@michaelgarland579]

So I have yz125 2003 is mine any good cause I have old kind round ?? An I changed my piston yesterday an numura pistons are dam good at 25 hours it looked good this is 3 piston I changed on this new cylinder so it has 75 hours how long will this cylinder last ? Upallnight

[@UpAllNight91]

Yes your 125 has the round type and is actually ok. The cylinder can last for about 250 hours on a slow rider but maybe only 75 hours on a fast rider. Just depends on the rider really.

[@michaelgarland579]

Okay I noticed yesterday that I'm having alot of vibration on chain an bike I sent video to my mechanic guy he said something is wrong to bring bike to him let him hear it he said a gear broke or something isn't aligned on clutch side so an another thing is when I took motor out last time I didn't put engine rubber piece in now it has slop when I lift bike up so that's my fault last time I took engine out he did noticed that 2 days ago I always have trouble putting clutch cover on so I take it to him he helps me like my mom says I ride bike one day then work on bike next day lol

Ok thank you for your help! Great content.

Thanks!

[@scotwelch1105]

Does this mod apply to the 2022 yz 125 ?

[@UpAllNight91]

It can be done on any bike. The YZ125 has a round type spring, so you would have to bend the straight tab of the spring in the direction to apply more overall spring pressure. However I can tell you the YZ125 really doesnt need this mod. The spring they use in the YZ125 is actually sprung well enough in stock form.

[@joelatkinson2080]

More great information!!! Thanks for all that you do!!!

[@UpAllNight91]

Your welcome!

[@kellybrown6988]

29mm? I’m pretty sure it’s a 30mm, same as the steering head nut, right?

[@UpAllNight91]

I thought it was a 30 too, but the 30 felt too loose. So I stuck some calipers on it and it read 29. I then put a 29 socket on it and it fit like a glove. I dont remember them using a 29 before so maybe they change it?

[@1176hambone]

Wicked mod!

[@senergyheating]

Thank you, I’m tempted to do this. I run 75w oil in my transmission. I’ve heard other mention using 10-40 oil for smoother shifts, what do you recommend? Have you used any aftermarket clutches?

[@hiphopaDIZZL]

looks like atf which is my what I run as well. trans just feels so tight with it

[@UpAllNight91]

I use shell rotella 15-40. Almost anything will work though honestly. But rotella has a lot zinc in it which is good for metal to metal wear resistance. A set of clutches usually last me for ever so I dont have much experience with aftermarket clutches for myself but on customers bikes who burn through them we have a good success with the tusk brand clutch plates. They are priced well, fit good, and seem to work well.
