yo havent been on in a while due to still sorting out the vivacity lol near on running correctly, hooked up the koso af meter and was running rich so have gone down in jet went to check and broke the kickstart so fitting new one 2moz woop lol but thought i would check clutch and roller set up as it didnt kick in straight away when i test rode it i have fitted green motoforce clutch springs (iirc are softer ones out of the 3) and 7.5g rollers, does that sound right?
I had 7.5 in my speedfight and was spot on but all 50/70 ped are all different trial and error is the best bet
