New to forum as i currently have a 180 runner but am looking to buy gts 250 ..have cash but still looking and researching !! I notice there is alot of talk about the limiter.. does the so called black box remove the limiter in any way and is there not a simple electronic solution to stop the limiter or could someone tell me how the limiter works ?. Also when i buy one i want to keep the standard exhaust but would like a bit more performance could someone advise what are my best options ?... Idea

On a standard engine why would you want to remove the limiter?? Its only job in the world is to stop the engine over-revving and putting its insides on the outside.

If you find your getting to the limiter a lot and wish to gain a couple of mph then like has been mentioned alter the drive system and effectively alter the gearing ratios.... Wink

Thanks for the advice i will hopefully fit a variator and belt .. I don't want to blow it up so i do understand the reason for the limiter but are there any other goods mods for say improving acceleration and midrange ie the 'black box 'any ideas would be apprieciated... Question

I think the J.Costa variator is the best option for improving acceleration. It certainly did the trick on my GT.

Yes, I have tried a Malossi variator, and I have tried it with Dr.Pulley sliders. The sliders gave very good results, but the Costa is better, it is very well made and I think it will outlast all the others.

Don't know anything about the Polini, except I have heard it is better than the Malossi.

ok guys, so if i should opt for the j.costa variator is is best to change the belt also and if so which belt is best ?.. I still would like to know is it worth me getting the pm black box and bearing in mind i want to keep the standard exhaust ???

std pipe

j costa variator

standard belt

no PM black box

short vespa flyscreen

big smile Cool

but to be honest if you'r buying a new GTs you might as well wear the standard belt and rollers out first and get some use out of the variator that comes with the bike before changing anything, when you need a new belt and rollers just fit a J costa and a new std belt, job done Cool
