TMAX 500 Slider Weight Comparison (15-17g + 19g Roller Weights)

[@bluntp.n.i.c7701]

I'm jealous of your scooter man

[@alanturner5688]

I really like your videos and appreciate your tech knowledge …I have had all three Tmax models the latest being the 560 . I’m also preparing the the 560 for dr pulley sliders soon….I have the 17 gram dr Pulley sliders in the 530 and they sure make a substantial difference . Hopefully the Dr Pulley sliders in the 560 will be a success . Regards from South Africa

[@49ccscoot]

Good luck with it. I've heard that newer TMAX models have a better performing variator or CVT to keep the revs up more. Not sure if that means different weights for best results, but it sounds like you can get much better results with tuning than the older TMAX like mine.

[@akybosule]

Tmax 500,2008,16g sliders with Malossi variator,top speed stops at 160km/h.

[@49ccscoot]

Pretty much the same speed I get with the stock variator. 100MPH/161KPH GPS (~105-110MPH on the speedometer) is the fastest for me. I'd hope that RPM stays closer to peak when accelerating with the Malossi variator though.

[@JoeKickass324]

Yo, man I was wondering if you can make a video how to repack a silencer on a pipe. Thanks!

[@spriggan1990]

built-in variator does not spoil the motor and all that?

[@49ccscoot]

The original variator works pretty well, but aftermarket options are much better for performance. I have new videos showing the difference that a Malossi variator makes.

My Zuma 02 mods so far are - 70cc sports chinese kit - Leo vince tt exhaust - Polini Variator at 6 grams sliders - 90 main jet - one penny sized hole in airbox This setup top speed around 80-84km/hr (no problems so far but going fast enough to break variator guide slides) When I tested the main jet at 95 and two air holes, The ride was the faster, but easily revving above 10,000rpm which is the upper limit of recommended rpms before cranks breaks, so I covered one hole and changed jet to 90 I believe it's time to upgrade Primary gearing so I can go faster at lower rpms. Got some questions tho - Do i need a performance crankshaft? - Is it easy? or do I need specialized tools - Gearing Ratio appropriate for my setup and model - Helical or Straight gearing and what brand recommended? - Got Tutorial? - What top speed to expect from setup

[@49ccscoot]

Gears or heavier rollers/sliders may keep it from revving so much, but if you get the best performance at 10,000RPM I'd suggest getting a better crank. I'd think you'd do better just a bit lower. The ZX typically peaks at 9,000-9,500RPM and the TT is supposed to be a little lower than that. I have a couple of crank install vids . You may want to get a case splitting tool for disassembly. Many do it without it. There's also a crank puller tool that can install a crank, or I use it to adjust crank position side to side if needed. Many use a tap with a hammer if the crank is not centered. I prefer not to hit anything (especially cranks) with a hammer though. 49ccscoot.proboards.com/thread/1225/installing-bearings-crankshaft-videos 49ccscoot.proboards.com/thread/351/engine-transmission-disassembly 10:1 to 11:1 final drive ratio works pretty well for most with Minarelli engines. Helical, straight... whatever you can find to get to the ratio you want. Malossi, Stage6, Polini... just stick with the good brands and you should be alright. I don't have a gear swap tutorial. I have bearing swap vids from a different scoot, but it shows a lot of the same process that you'd need to do. kzbin.info/www/bejne/g6msiGqGn8SBe6s Top speed in the 50MPH range somewhere. Maybe 60 pushing it full tucked.

[@JoeKickass324]

Cool thanks, You answer my question perfectly XD. Imma get a stage 6 gear and remember to put gear oil in XD thanks to your video warning people to.

[@raymondbetancourt6498]

Have u tryed mixing sliders or what would you recommend. What’s a good size to mix them at?

[@thedaydreamer7972]

Hi, I am upgrading my scooter, should I just replace the rollers and springs in my pre-existing variator and clutch if they are in good shape, or does it make a big difference to buy the "performance" assemblies from amazon? Also, what do you find to be the best preforming setup, if you have lighter rollers in your variator should you have tighter clutch spring, or do you need heavier rollers with tighter clutch springs? TY for all your help

[@49ccscoot]

I prefer to either just tune the stock CVT or buy quality stuff like Malossi. Rollers and clutch springs don't necessarily relate. You don't have to have light rollers to use stiff clutch springs for example. Tune each to work the best. If you are working with the contra spring and rollers, then you do need to remember that changing the contra spring will change how the rollers work.

[@metalcidar]

I am curious about the top speed. Which slider has the top speed? 19g or 17g or 15g? Thanks

[@49ccscoot]

I would expect 19g. Haven't thoroughly tested, but the lighter sliders got RPM up too much for me and it didn't do as well at the very top of the range.

[@techcarp]

The heavy ones have big top speed low rpm, the light ones best acceleration from 0 and same top speed like original rolers

[@thelowlightsmusic]

I have an 09 Tmax and since I'm replacing the VBelt, I delved into replacing the sliders. So I would guess from your tests that 16g weighs would be ideal to maintain performance and acceleration. I like how my oem pulleys feel, what do you think would be the most noticeable changes going from 19 to 16g weights?

[@49ccscoot]

16g is what I stuck with. You could go a little heavier and keep RPM down more for cruising if that is more of a priority. The biggest thing you'll notice is acceleration from 30MPH up. Below 30MPH, I think the clutch is not aggressive enough. They do make clutch kits for them, but I think if it were aggressive enough to make it launch much harder, then it may be less than ideal for day to day riding.

[@thelowlightsmusic]

@@49ccscoot Thank you! As well, one other thing about this roller weight replacement, there are also these clips or inserts that are sold separately. Are these necessary to replace when doing the roller weights? It adds a layer of confusion to the confusing search for the appropriate weights for the bike. I found through conflicting posts, that 25×15 was the dimensions for the TMax, but do these "clips" also have weights to be considered?

[@49ccscoot]

@@thelowlightsmusic I think you must mean the guide bushing thingies. You don't have to get them unless the stockers are worn out, and they don't have weight specs to worry about.

[@begara6451]

Which slider weight is optimal for a 50 cc minarelli? I am using BGM Supertune variator which is you could say a copy of malossi multivar.

[@49ccscoot]

I'm not sure if you'll find optimal without some tuning. I'm more confident with a recommendation on the TMAX because I think the quality control and tolerances will be tighter across the board. I'm used to Chinese Minarellis and the contra springs will vary and that alone will throw off any recommendation. In general, I have done well with 4g rollers in a stock variator. I believe 5g sliders in a Multivar clone, but with a 1,000RPM contra... but then not every 1k contra spring is alike and the clone variators may be a little different and any changes to the engine will affect it.

[@johnoleary9317]

Thank you for video . Have a 2003 MK1 tmax. I am fighting against previous ownership faults. Flattened 19g rollers with 3g inserts. Since watching your video. I have bought a set of 15g & 18g Dr Pulley sliders. New belt fitted Blue contra spring. All assembly cleaned and greased. Your opinion for smooth acceleration (not concerned about top speed) PS. I have kept the 8 x 3g roller inserts and they fit in the Dr P 's. John.

[@49ccscoot]

16g with everything else stock works great for me. Mix the 15 and 18 to get 16.5g equivalent would be my guess.

[@johnoleary9317]

I will try 4x15 4x18 Thank you For ALL your video 's.

[@ssoffshore5111]

What's involved with making this change, what has to be done to take it apart?

[@ssoffshore5111]

BTW, good informative video, thanks!

[@49ccscoot]

Thanks. You have to take off a bunch of plastics to get to the CVT cover and remove it. You'll need to make or buy a tool to hold the pulleys too. bigwheelsturning has info on that and vids. I would suggest getting a copy of the service manual. If not for all of the body parts, it's not really a big job, but having to remove and install them adds a lot of time.

Hi, I want to put dr pulley on 1st generation. On sale there are 16 and 18 gr. What should be the best fuel economy and dynamics in the city? and maybe you know, whether it is necessary to lubricate the rollers, according to the manual for 1 generation, lubrication is necessary, but as I understood only for the first type of rollers. Тнanks!

If 1st gen is the same, I'd say 16g. I don't lube the sliders, but I lube everything else as the manual says.

It can vary by variator design, but I'd guess try similar sliders first.

@@49ccscoot Thank you very much.

[@zul5679]

👍👍👍

i don't want a fast scooter. i just want a high accelerated scooter. and of course without compromising my fuel. what grams should i use ? - any suggestion ?

[@49ccscoot]

16g would be my choice based on my experience with the TMAX 500. Going lighter didn't improve acceleration beyond what the 16g sliders did for me. If you still want more, you may want to look into aftermarket variators.

@@49ccscoot meaning - the heavier the weights the more power it accelerates ?

[@49ccscoot]

@ Heavier = lower RPM, lighter = higher RPM

[@JedTaneo]

@@49ccscoot i thought heavier weights means high rpm since it stays longer on low gear before pulley opens to shift high gear.

[@49ccscoot]

@@JedTaneo Heavier weights make it shift more quickly and maintain lower RPM. Heavy weights overcome the force of the contra spring to shift the CVT at lower RPM.

[@kindajal]

can anyone tell me how tmax transmission works? i mean there are clutch friction plates and rollers? so from engine to which then to belt drive?

[@49ccscoot]

The TMAX has a wet clutch so the clutch should operate and then the CVT and then to the drive belt or gearbox (depending on the year of the TMAX).

How is it breaking?

[@peregilhagen922]

Light rollers get less speed and stronger. Heavy rollers, higher speed on the road.

[@49ccscoot]

Simply speaking, yes. But not totally. This is how most people think about rollers/sliders, but there's more to it. It's about keeping in the power band and keeping enough weight to counteract the contra spring so you can't just keep going up in weight to go faster or keep reducing weight to accelerate more quickly. Gotta find the sweet spot.

me again i put 18 gram in my 150 it sucks its like a car with a 3 speed tranny it needs another gear follow me?

[@49ccscoot]

I get it. If belt length is good, you've been through roller tuning, variator is in good shape, and the torque driver is clean and moves freely without any spring bind, then it should be working as well as it's going to.

no i put 18 gram rollers and they suck.
