JayR Glad you enjoyed the video. :-). Thanks For Watching. Please share and rate Thumbs Up

electronicsNmore are 6.5grams good for my taotao 50cc

what are you gay

I agree.

electronicsNmore this must not be a 50cc, that roller weight sounds real heavy for a 50

Hi Kevin. Most people, like you, are highly appreciative, but there will always be a small number of ungrateful lowlifes out there. Many are trolls, jealous because they cannot produce a good video, or just get off on being miserable. Every channel has them. :-)

Fairly inexpensive to do!

Thank you dude!

Weights are too light when that happens.

Thanks, you have really helped me understand, will be purchasing from you guys in the future!! 😊

Cajun Kevin my 2016 TaoTao Motors 150 came with 12g rollers which I have already changed 215s I seem to get a better overall performance out of the 15s

Check the valve clearances according to my other video, as well as inspect the intake manifold for cracks.

You're welcome!

Shure I will Mate!

3 little springs?

Similar, but not exact.

Never use grease!

@@electronicsNmore ok thanks

N.v

Thanks Mike. Be sure to share and rate Thumbs Up! I buy much of my parts off Ebay or directly from China,.

A torque wrench is only used to tighten bolts.

Worn belt or the variator roller weights are too light.

Enlightened News Be sure to check out my GY6 video playlist and share. Thanks!

Climbing hills requires using lighter rollers.

Glad you enjoyed it. I have many other excellent videos, be sure to check out my video playlists, rate thumbs up, and share my channel with others. Thanks!

I think it's around 35-40 Ft Lbs. I just made sure it was very tight, and applied some loctite. Never any issues. Thanks for watching!

George Roberts You need to buy an inexpensive digital scale.

I know how to install them lol, but this was a little scary.

Robert which grams did u go with I have a 50 cc toa toa

Sliders are good.

No, the oily residue ends up on the belt making it slip. I've used a thin film of powdered graphite for locks with no problems.

It will work, but how it accelerates and top end speed/engine RPM will change if the weight is different than what's installed.

No oil or grease

@@electronicsNmore why not? What issues will come?

@@Sidg2 Could get thrown all over the belt and make it slip.

@@electronicsNmore Is this theory also correct that after applying grease on round rollers they don't able to roll properly and tends to slide which cause irregular flat sides. And these irregular flat sides causes vibrations on certain speed? Is it right?

Just buy an upgrade kit from 150cc to 180cc. The 250cc might be too big to fit.

Hi Mike. Sounds like a lot of debris needs to be cleaned up. I suggest borrowing an impact wrench and removing the variator and clutch for easy cleaning. Thanks for watching!

@@electronicsNmore thank you

No idea, never saw one like that.

No, it will rattle too much. Use the same size it came with.

I used 15gm.....take out the old rollers, and weigh them.

electronicsNmore Thanks👍

The engine will rev like crazy before moving using weights that light.

Has the engine RPM increased at idle from the norm?

Place the oil filter strap wrench around the edge of the variator to hold it.

Scott Milnes just find someone who has a very powerful drill, preferably a corded one that plugs directly into a socket, they are always powerful enough and u don't even have to hold it from spinning, it'll spin a little but the nut will come off so fast it'll barely have time to spin, if u don't know anyone who has a high powered impact driver u can rent them cheap at places like home depot and free and some auto parts stores

You need to pinpoint the location.

+salisburyplain998 Maybe try 1 or 2 gram heavier rollers. The engine will rev less off the line. You may also need to inspect the clutch.

cheers thanks for the reply,Ill give it a go :)

+electronicsNmore Was this for a larger than 50cc GY6? The largest rollers I've seen for a 50 is 7 gms.

Don Diller The procedure is the same for 50, 125, 150 cc scooters. Many sizes available.

I just put 9 gram ones on my sunny 50cc when my belt went 8k. up hills its slow 15mph faster on flat ground 40MPH up

Lower weight rollers will cause the engine to rev a lot more before you start to move, and cause the rpm to be much higher at top speed. For best fuel economy, a heavier roller is best, but you lose speed on take off.

What about those people putting 18 g rollers in? I live in the mountains with lots of hills.. so would you put 4G rollers or 18g? I'm think of the 4G cause 0 to 35 is all that really matters as long as it can steady pull me up a hill doing at least 20 to 25..your thoughts on roller weights and driving up hills?

@@youngbuck22481 ,. The confusion here rests between 50cc and 150cc GY6 versions. 50cc scooters used weights around 5 grams and 150 around 15, that's just ballpark numbers I guess....

No, heavier rollers tend to give a higher top speed, and better fuel economy.

Sets when the clutch shoes push outward to engage the clutch to make the rear wheel rotate.

All depends on the terrain, or if you want good fuel economy. 14-15gm is ideal for hilly areas, and 18gm is good for flat areas where fuel economy and highest top end speed is desired.

What is a good roller weight for hilly roads?

All specs can be found online in GY6 manuals. Thanks for watching!

It's personal preference. First remove one that's installed and weigh it.

@@electronicsNmore thank you for answering.

Hi Brent. I personally would not touch the jet. If you switched to a larger bore on your engine, then yes, otherwise I would leave it alone.

So, do you think that with the Naraku vario and stock cdi will give me that little extra take off?? I dont know the weight of the stock rollers yet! And with the Naraku vario came 2 sets! 6 at 10.3g and 6 at 11.4g, i guess with normal cdi and new hightened ramp on vario its just a case of getting the roller weight combo right for mostly in city but also runs out country roads!! I dont expect a rocket or i would just sit my test and get a bigger scoot but having bad back problems a scooter was perfect for me, and i am actually surprised at how well my little Kymco being very basic but is still good for sitting at 60mph, but most as i said is downtown and just need that bit of pull to feel safe in traffic to get out the way!! Thanks for your reply!!

I know nothing about that particular scooter. You are going to have a lot of testing to do to get it the way you want. There is no simple answer.

Thought so, thanks for you help!!

You're welcome!

+Blaq IVen Those springs go in the clutch.

I don't understand why they would be in that kit do those go bad when variator does?

Heavier roller weights will give slower take off, but help on top end. Thanks for watching!

Bad idea. Use a very thin dusting of graphite powder for locks.

Why is that

Great video btw I'll thumbs it up as soon as I am done typing this. Very detailed.

+Gregory Megatron Hi there. Using lighter rollers will cause the engine to rev more before moving(higher RPM). The result is more torque up hills and off the line, but usually the top end speed will be a little lower, and you will not have as good gas mileage cruising down the highway as heavier rollers. Thanks For Watching!

Ok thanks for the quick reply! Honestly I don't quite need to take off quicker and would prefer any high end that I could get so maybe I should go heavier than stock.. Or here's a dumb question: changing the stock rollers with the exact same weight but higher quality do anything different or no? Also have you tried experimenting with removing every other roller?

Gregory Megatron Quality is irrelevant. 18 grams is 18 grams. :-)

That sure is a nightmare. I sold my scooter. :-(

No

Heavier rollers usually give you a higher top end speed, but you'll lose some speed off the line. How much? Every scooter is different. Thanks for watching!

@@electronicsNmore Thanks, its for yamasaki 150 they havent been changed in years so I want to put good variator and rollers. And will sport variator with rollers be good and speed it up a little bit, his top speed is 75 km/h and I feel it chould go faster.
