Koso 28 setup with machined Polini 130

[keuk]

I ride a smallframe with machined polini (+5mm..), Malossi Gravediggerised cylinder head, pm40, Koso 28, polini manifold with tassinari reed, spark W4AC, HP4, 4th DRT, Cranck Mazzu anticipated, Ratio 2,86.

I tried this setup

Mainjet: 132

Slowjet: 38

Neddle: JJJ 2nd clip position from the top

Air screw: 1,5

It works nice but the spark looks a bit white....

I tried 138 for main jet but i have to put the first position for the clip ans the sparks remain white.....

Do you thing it could come from the slowjet, or i maybe should try the JJH needle ...

Yes it seams to be a good idea... i will test that. W4AC is more for a plug and play polini. Thanx
