cheers dude! will do

[ninjaman1138]

it did for a while, i havent really got it sorted out yet.

i have to get the idle mixture right on my bike. when i had my pro cdi on, the bike kept cutting out when i stopped, i had a hard time keeping the bike going. so i removed the cdi for the old one and the problem was solved. i think the cdi does help, just make sure your bike is up and running properly first.

did the cdi work?

[dannystar01]

hiya mine wont go faster than 45(mph) is that unusualy slow??

[ninjaman1138]

@dannystar01 i try 17 front 36 back with ratio of 2.1, that gave alot of speed in the first three gears but lost in forth and completely dropped in fifth. originally i had a 17 front and 49 rear (i think) ive only ever been able to reach 50. i think there may be some device that limits its speed.

does the engine sound like it has more to go before top, mine does.

[ninjaman1138]

@dannystar01 @dannystar01 im having the same problem at the moment, mine wont go past 50mph

i will try my performance cdi at the weekend. hopefully that may help

what sprockets do you have on your bike, front and back

i have a 12 front and 36 back giving a final transmission ratio of 3, which is supposed to be ideal.

Try calling ooracing for advice on tuning these types of engines.

They helped me out alot with my Monkey bike!

did you get a new spark plug? if so what one and from where? thanks :)

[AndyBradley]

i did get one, i think its a dte8 or somthing. ill check it and get back to you. xian racing have gone bust so you cant get any of their bits any more. good thing really, i havent noticed that much change in the performance of the bike. keep an eye on rust on the bike. kill it as soon as possible. if you put a performance coil onthe bike remember to widen the gap in the spark plug, a larger spark requires a larger gap. i havent done this yet as im lazy!

[ninjaman1138]

i think that changing the front sprocket to somthing lower will maybe give a little more top end. i am going to get either an 11 or 12. their only £4 on ebay. wait till i sort these things out, at least that way you can benefit from my spending £70 and not really improving anything. though, if you want a quick fix, then changing the front sprocket may help.

[ninjaman1138]

to be honest, i wouldnt recommend any of the mods. i cant notice a damn thing with them. jetting to 100 from 94.5 has only caused hassle. i dont think that just bolting it all on is the way to go. i dont recommend the filter unless you know how to set them up. i thought it was a case of put it on and thats it. when you get the bike check the sprockets, mine came with a 17 front and 50 rear.

@ninjaman1138 if you take the plate of the end of the silencer and cut off about a inch of pipe you can get 3hp more and use 46 teeth on the rear and 12 front im geting a top end of about 65mph and set the valve clearance to 0.8mm for a further 4 hp mine has got around 19hp from the standard 11hp

[bruestore]
