Thanks you very much Mr. Praino. Iam now in the middle of super international.. the first two race i use rocket car and it was was easy win.. the third rather difficult.. what car should i choose to make super international easy win.. and do you have tuning tips for gokart 125 shifter.. many thanks mr praiano.. sorry for my bad english..
For the gokart 125 shifter ,the only things you can tune are the gearbox, power limiter and ballast..
Taking out some power or adding some weight would be prejudicial for the performance.
The only situation where you could play with this would be a championship with some weight handicap in the way of power handicap. Less power is just slower, but more weight as ballast open a new setting possibility, moving this weight and trying to let the kart more balanced....... If you have to race with some KG anyway, you need to find the best place for it.
The gearbox of course offer the same tuning options as a car and looking at the peaky powerband of the small engine, sure a close ratio gearbox must offer some better performance. You have to adapt it to the track and also consider that the close ratio gearbox will prejudicate your standing start at a certain point.
You just need to test and find the best compromise for each track and race.
For a long race it´s better using a very close gear ratio gearbox because the start become less important.
For a short race, a good start is primordial.
