on a dna 50the clutch springs have been changed,engine revs have to be at 7000rpm before pulling away.do you need to change the clutch springs back to standard,to get better performance after changing to a sports exhaust

you might just need a new belt or lighter rowles go on the internet and find out the weight of your standard rowlers and then go a couple of weights below

the stronger the springs are the higher the engine has to rev for the clutch to actually grab hold of the clutch bell. stronger springs will limit ur performance because instead of u pullin away at 2000 revs which will then speed up to top revs it is already at a high amount of revs so u dont have much money engine time. so basically put slighty weaker springs on and u will notice alot of difference
