I need some help

[Bmwgr650gt]

I would like someone who knows to help me, please. i own a c650gt 2013 model ,I installed a Malossi variatore with 22gram rollers, I change the white spring in the clutch and harder springs (the red ones),full Arrow exhaust system and air filter. I installed a switch to disable the TCS, but still couldn't improve the power from 0 kilometers up to 40 kilometers. I want to improve this delay it has. Can it be corrected by ECU remapping ? Thanks in advance

I've been following this forum for as long as I've owned my C650 Sport, which is more than 5 years. In all that time I have not heard of ECU re-mapping on these bikes. I have heard positive stories about owners installing Dr Pulley rollers and that making a big difference in acceleration. I recommend you do a search on the forum looking for key words such as Dr Pulley, acceleration, and Malossi, I think you will find a lot of good info.
Lastly, I think these bikes are plenty fast off the line without any modifications, but that's just me.

The harder clutch springs make clutch engage later, at higher revs. I would suggest softer ones, and a J.costa variator instead.

Do you beleave with softer clutch springs will be faster from 0-40khm ?

The delay you feel is likely caused by revving up from idle to clutch engagement, plus the variator flyout time.
Do you race, our just commute in the city? My advice applies to the latter case, because in races the initial startup delay does not matter so much as the power at all cost, e.g. crazily stupid revs and comsumption.

Then my advice fully stands.
If outlay for J.costa is unacceptable, you may try playing with roller weight in malossi, or use another spring that is ”easier”

I am be waiting 20gr rollers to check it. You mean easier for the 3 springs in the clutch or the one white Malossi where I have now ?

 

[Bmwgr650gt]

I use the 20 rollers but nothing happens the same acceleration from 0-50 and the variatore make noise . I will install the 22 rollers again.

 

[RollaCosta]

20g was stock roller weight, wasn’t it?

No Malossi kit including 22gr and 24gr rollers

 

[RollaCosta]

What’s the stock roller weight?

 

[Bmwgr650gt]

What’s the stock roller weight?

I think 33gr

 

[Bmwgr650gt]

But I feel something goes wrong because I replace the stock belt with Mitsuboshi . Is there any chance for this not to have good acceleration?

 

[RollaCosta]

Is it longer or shorter than stock belt? Shorter belts, like Bando, tend to accelerate faster but have less top speed.

 

[RollaCosta]

When you are changing everything, it is not a good idea because all these items are related to each other.
Unless you know exactly what are you doing, of course.
For the life of me, I still do not know why would anyone want “racing clutch springs”, because they engage later at higher rpms, and you basically have neutral for longer time, off the start.
The one use case comes to mind is roaring your exhaust at stops. Hmm…no thanks

 

[RollaCosta]

By the way, as a full disclosure, i have stock transmission.
I have gotten faster by getting lighter and better exhaust with GPR Furore Evo4. Shall I call him “Fuhrer”, it’s all black and German
I have the J.costa sitting in the garage waiting for stock rollers / belt to wear out. I shall need another set of costa rollers, heavier to be more like the original ones as by default my PRO version will roll at 7krpm on starts, which is too much for me, need heavier set 23 or 25g not sure yet.

 

[Bmwgr650gt]

All good guys I find the way the scooter flying, dragy 4,2 sec 0-100khm top speed 203 gps it is amazing know thanks all

 

[RollaCosta]

Great. Care to share how exactly?

I bet he changed the CVT belt. Mitsuboshi belt is for stock variator, but he had changed to Molossi variator. Probably needed Molossi belt to go with it.
