Did you figure out how to remove the cover? I took out the three 8mm bolts and the allen key bolt at the rear and it won't budge at the rear (some wiggle at the front). Not sure if i'm missing something or whether to just pull more). Help appreciated.
So, as per your comments the cruise speed it's the same but 1.000 rpm higher. That's is the reason why you want to put the original back, right? Are you thinking in another variador like Malossi's?
Thanks for your answer. I'm not sure. Do you recommend J.Costa variator in order to improve the acceleration or it's just waste money? I'm looking for the new NC750X with DCT !!!
Yes but just slightly different J.Costa model number they do 2020/2022 version and a 2015/2019 version but basically the same..If your thinking of buying one get the 2019 version but use the same 11g weights
Acceleration is improved without sacrificing top speed or cruising speed only drawback is it sits higher in the rpm when variating so fuel economy suffers but still around 110mpg also much smoother operation
And how J. Costa improved acceleration? What roller do You install? Any differences in top Speed? My still waiting for package and personally top Speed right now is ok but acceleration.. I ride pretty all the time 2 persons, where I live is many uphills so You probably understand me…
@@BigBoyzToyz1974 yeees! I just can't wait for my package! What is Your total milage? Next week first oil change and in case of that mounting variator. I will give You sign how Yasuni fit and my experience so stay tune 😁
Hi mate I have a 2019 forza I changed the variator yesterday for a jcosta one. I noticed when I slow ride the bike feels quite jerky jittery do you know why this is
Nope sorry. But fault finding diagnostic did you put the 2 washers in so the belt drops lower also did you change the belt as if on original it can cause a few issues a v belt is best.. mine was fine so can't really say without riding yours
Hi first of all very informative video thanks again for sharing I made mine with your help, I have a question how much is the normal weight of the J costa rollers? I have the blue ones like yours
It's a strange one it does work and helps engine to pick up quicker.but using lighter weights in your original will do that. I kept it on for 400 miles then put original oem back on...so I recommend if your original has come to the end of its life and needs replacing then yes its good but to change for performance upgrade its miniscule returns..I do have videos with it in on my channel...good luck..
Do you understand the j costa varimstik what weight do you need for yamaha n max 125 ccm on the j costa it has 7g I think it is a bit heavy it should be 9.5 or 10g what do you think?
Don't really understand what your saying but if you think 7g is too light what are your symptoms is it reving too high you want the Variator to be at about 7500rpm as accelerating...my forza original weights are 13.5g but the j.costa were 10g
I’m actually selling this one on the video if took it off put original back on. Reason is I like the extra acceleration but don’t like the rpm being 1000rpm higher at cruising speed.
Exactly the same result as installing slighly lighter rollers on the stock variator = higher rpm. 5£ rollers vs 160£ vario - J.costa is a big waste of money.
I agree it is better materials and slightly smoother but unless your original has broken or worn out J Costa is a waste of money...like K&N air filters also aftermarket exhausts do nothing for performance but the company's still make a fortune selling them...
My engine side cover doesn't look like it only has 3 bolts and still wouldn't come off didn't want to force it it's a 2020 model any ideas ?

where to buy that E017 holder and how much is it???
Amazon about £20

No mate I'm satisfied with the stock setup if I want a faster bike I will buy a bigger bike im really thinking of getting a cb650r for weekend fun

J Costa definitely gives you much faster acceleration but mpg will go down my priority was economical transport 👌
@@BigBoyzToyz1974 understood. More acceleration more fuel ⛽️. Thanks mate
Great videos on the forza picking mine up hopefully tomorrow. Have you applied acf50 over the full bike by any chance. Keep the great videos coming
Hello Ian thanks for the feedback bud, did use acf50 but only on the engine cases and rear shocks
Is this the same for the 2019 forza
Yes but just slightly different J.Costa model number they do 2020/2022 version and a 2015/2019 version but basically the same..If your thinking of buying one get the 2019 version but use the same 11g weights
so how is performance after upgrade???

Washer is optional, drops your gearing slightly, thats why it was more revvier....run it without washer, you may like it better.
Did that not mess up your warranty grate playlist BTW
I suppose it would if they investigate but as long as you put the original back in for any warranty claims I can't see an issue.
I Say great 👍 .
Excellent, keep good work Up. 🎉 🎉 where can I obtain these Variator costa , so in brother 🙏
Low stock everywhere ATM.
And how J. Costa improved acceleration? What roller do You install? Any differences in top Speed? My still waiting for package and personally top Speed right now is ok but acceleration.. I ride pretty all the time 2 persons, where I live is many uphills so You probably understand me…
Acceleration is much faster I used 11g weights top speed is estimated 80mph it doesn’t seem to effect top speed but acceleration greatly improved 👍

@@BigBoyzToyz1974 I never received washers in my set also I’m using the original belt
@Josh9265 that will probably be it is picking up higher up the Variator so it's like it's starting off in a higher gear

Brilliant video.
It would be good to see a video of a ride after fitting.
Has it made much of a difference? I have a 300 forza 2018

@@BigBoyzToyz1974 you can just use slightly heavier rollers to bring the Rpm Down such as 12Gr :)
@@tylerraines3451 I did use 12g aswell performance was the same as stock Variator
@BigBoyzToyz: and which rollers did you use with the higher rpms?
Exactly the same result as installing slighly lighter rollers on the stock variator = higher rpm.
5£ rollers vs 160£ vario - J.costa is a big waste of money.

On the video Jcosta seems significantly quiter compare to the OEM when runs without cover.
Does it...I didn't notice
