if your dep rusts, gutt your standard exhaust, its better than a dep and dont rust anywhere near as fast :)

Yeah so ive read.can any one tell me why after warming the bike up for say 10/15 mins ,i take it out up through the gears in to top and it will do 70mph @ about 9 grand and pulling strong,then for some reason will cut to 65mph after a short time .

yes when you tick bike over it takes charge from the battery, when the alternator kicks in it returns voltage back to the battery

if you are warming up the bike it will deposit more voltage to your battery

when driving your alternator will get used, when you hit powerband any voltage not coming from engine to make up for the powervalve will be drawn from your battery

this will be why it is dropping power after a while of riding

if it was compression it would be like that all the time as you have expanded the barrel size by the heat of warming it up smile.gif

check battery voltage and check that it is holding charge

when charging check the mili amps reading(if you got a decent enough charger) smile.gif
