Hello,

i was think about make some modification on my carb,

Please read page 10:
http://sarahturnerphotography.com/do...40%20Bible.pdf

this will do a fast response for the ATV ?

I have also Magnum 1995 425cc, the response of the carb in low RPM is very low.



my jet needle set now on 2. (if 1 is Leaner and 5 is Richer).


for exampe i have Sportsman 500 4X4 98 and Magnum 425 2X4 95.
after replace the primery spring for both of them from 20-90 to 70-200.


if i push on the Gas grip on the end. the sportsman make litte wheelie,
and the Magnum not, because it dont have good start.

thanks.
