[quote=“jands”]Today was a Happy Day! I have found a mod shop in Kaohsiung (Chung wa 1st Road). The staff there were extremely friendly and helpful.
The first thing they told me is that I need to wait until I have done 3000km before performance will improve.
The second thing is that they taught me how to break the scooter in.
0-1000km = No faster than 100km/h and change the speed constantly (hit 100km/h then let it drop back to 80km/h)
At 1000km try to get it past 100km/h.
Then keep doing the 100km/h down to 80km/h for another 2000km.
They said that the unmodified Yamaha is well know for poor acceleration from 0. But I can make up for it in the mid-range.
The variator and exhaust mods are the best thing I have done. If I still want more power I need to get the bigger cylinders (150cc) and change the carburator/CDI box. When I change the carburator the TPS will also be removed (because it is attached to the stock carburator).
They Malossi cluth springs will give me a slight improved acceleration.
The Malossi clutch and torgue driver are for modified engines and they will only improve the mid to high range speed.
They advised me NOT to get a new cam as the performance gain is minor and it will only keep on buring out.
The only other thing I can do for acceleration from 0 is to get some GOOD tyres.
are all those 100-80 etc all really necesssary? I tho to break in a car you just take it easy on everything for the first 1k miles…but on a biike you gotta do all those? hmmmmm are those really necessary
