does anyone know what gram rollers come in a standard zip 50

how much do they weigh coz i cba to take off the variator just to check.
cheers

 

Standard rollers are pink coloured 19x15.5mm and weigh 7.2grams... when derestricted with the standard pipe they are recommended to be replaced with 6.4grams.

 

thanks, my zip is bog standard and i just put a leo vince tt exhaust on and the accelerations is shit....although im going to upjet how much ligher rollers do u think i should buy to get the best out of my exhaust....5 grams???

 

5.5 gram rollers i'd say. but have you de-rizzed the variator? also the exhaust may have the restrictor cone still in it

 

i put 5 gram rollers in and its alot better now and the variator is deristriced.
my leo vince tt exhaust is very loud ale: ....im not sure if its restricted or not, how would i find out?

also, is there any way of making the exhaust quieter?? its too loud but it might be blown
any help?

 

First thing to do is make sure its sealed properly.... if thats all fine, then i would assume the end can needs repacking. Buy some cheap baffle-pak from ebay or similar, normally only about £3 a bag and repack it.

 

ok ill give that a try, ive also noticed a dent on the pipe near the end where it connects onto the cylinder.....could this be a reason why its so loud?

 

start the bike and move ur hand around the hole of the exhaust and see if u can feel any air, then ull know if it has a hole, not tight at the cylinder or ur end cans leaking
