Benjidt-x Posted February 2, 2010 Share Posted February 2, 2010 Hi there mate there's a black and green stripped wire that goes into the back of your speedo cut that wire and make it a little bit longer so that you can earth it out to the frame i.e bolt it to the frame that way it cuts the ypvs restiction out which will make your bike pull harder and give you twice as much revs also on the back of the inlet where the reed vavles are there is a big black bit of rubber that you need to cut off that means your bike will get more fuel and more speed also a 17 teeth front sprocket and a 57 back sproket will increase top end and acceleration at the same time and there is also the obvi of gettin a full dep exhaust system or arrow either of them would work Link to comment Share on other sites More sharing options...
Ryan09 Posted February 4, 2010 Share Posted February 4, 2010 If you adjust your gearing then your not going to improve top end and acceleration, its only one or the other im afraid. Id personally leave the sprockets alone. Link to comment Share on other sites More sharing options...
