Hi new here, speedfight 2 a/c 08, need help tuning??:)

.,.

 

Ok thanks

 

Welcome fellow Speedfighter.
How fast can you go on yours?

 

Hello well it's got 50 mph on clock and it goes a little further then bounces so just over 50 you??

 

Got mine to 55 (on the speedo) on the flat and almost up to 60 on a slight downhill slope.
Still experimenting with different setups at the moment.
Currently got a 76 jet, Leo Vincent exhaust, 7.5 gram rollers and a motoforce variator.
No idea what I'm doing but it goes twice as fast from when I bought it.
Seems to run loads better without an air filter although that's not a good idea.

 

I've taken my performance pipe off and replaced With the one I had with bike, it runs a lot better slower from 0-10 but much much faster from 20-45 but it does about 48 flat out which is fine by me, any tips to get it faster from 0-10

 

& I'm not sure if its the standard pipe it's ginda the same but with a carbon fibre piece on the end

 

Lighter rollers?
Mine does a similar thing. Was. Slightly better with lighter rollers.
I'm gonna go even lighter and see what happens.

 

Ok thanks I think I have 6 in now, also when I pull off there is a rattling under seat and footboard any idea?

 

Dunno about the rattling. Check for missing bolts and loose trim.
My bike came with a box full of 'spare' bolts that the youth had left over when he'd been working on the bike.
I seem to spend a lot of my time finding homes for these bolts and the rattles are slowly disappearing!

 

Yeah, I need one of those too.

 

Lol.

 

Hi all. I went out on bike yesterday and the rattle has gone! I don't know what it was but its gone

 

Check round your bike.
Whatever is missing will be the cause of the rattle!

 

Ok thanks

 

Very true Mark. What I thought was a carb issue turned out to be worn rollers!
