had rollers changed in my bike dunno what was in it but it would get to 40 easily but i put 9.5g rollers in n now it struggles to get to 30 wtaf
Mines a 125cc and i've just replaced the rollers with 9 gram instead of 8.5. very easy to do 65mph without pushing it. Maybe you needed a lot lighter roller.
The rollers are probably too heavy, they're fully engaging the variator at too low in the rev range stopping the engine hitting the powerband.
It has 9.5g rollers in and carnt find any lighter for the bike i have might just put the fucked up ones back in
Why don't you just drill out the heavy rollers to the weight you need? Simple enough, just gently hold roller with mole grip's and drill (keep dipping in water to keep it cool) the centres out. A small set of digital scales sorted!
why not find out what weight it had beofre so we know if they are too heavy or somthing else is the issue?
you dont have to have the rollers for your scooter. you just need the size, width and weight. Measure and weigh your old rollers in mm and gram
the thing is thought the standard rollers i had got the bike upto 45 n the new 1's i got barely get it to 30 n ive got 9.5's in
The problem with rollers is too heavy and they open too soon and stop the engine reaching it's powerband, result sluggish performance. Too light and they dont fully open, result engine reving hard but getting nowhere.
