Pulse Adrenaline Front Sprocket???

[xltomm]

I currently have a 13 tooth front sprocket and I am getting hardly anything out of my gears by this i mean i am in 4th gear doing just over 30 and i have to change because the revs are high. So i have bought a 16 tooth front sprocket and i was wondering has anyone else got one of these and if you could tell me if it has made a good improvement

Thanks

a 13 tooth must be terrible on your bike! plus you have small wheels which makes it worse. My bike has the same engine as yours and it has larger wheels and a 15 tooth as stock and I think thats it's almost perfectly geared. A 16 tooth should make it much better. I might be wrong but a 17 tooth might be best for pulse adrenalines if top speed is what your after but you have to order them from china.

Very nice mate you should take a pic in the dark with all the LEDs on that would be nice and have you done the bore kit yet

Nope it's still in the post, I've just ordered it so it should take about 2 - 3 weeks :(

I've been meaning to take some pics of it in the dark but I keep forgetting. I did go out once it was dark and I drove about a mile to find this good place with no street lights and a good packdrop, I got there and set up my tripod and camera, switched all the lights on and the bloody battery ran out on my camera >:(

you said you have changed your main jet what does it do??

[spencer2004]

Basically a bigger main jet adjusts the air to fuel mixture and affects the performance of the engine. In a lost of cases these bikes run too lean (too little fuel in the mixture) to meet emmisions standards or something. I went from a jet size of 97.5 to a 105 after I fitted my performance air filter and then to a 110 after I fitted my new exhaust, I could probably push it to a 115. You can test your air fuel mixture by doing a plug chop test (google it).
