Hello Ian thanks for the feedback bud, did use acf50 but only on the engine cases and rear shocks

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

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 !!!

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

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.

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.

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

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..

@@BigBoyzToyz1974 Oh brilliant ill check it out cheers for that.

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 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 😁

We wait you?!

Amazon about £20

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

@@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

Low stock everywhere ATM.

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

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

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.

@@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?

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...

On the video Jcosta seems significantly quiter compare to the OEM when runs without cover.

Does it...I didn't notice

I have got a tripod. Don't watch it if you don't like it nobody forced you 🙄
