px budget mild tune

[ducksta]

hi guys,my m8s on a budget and he has scraped a few bits together, so just by bolting on a malossi 166kit and a sito plus exhaust and drilling the air filter will this give a decent up grade for a px125 engine?

[acko]

The Sito isn't really a match for the Malossi kit.
A Polini kit would work better.
Failing that i'd switch exhausts to a Simmonini or Sterling if on a budget.

Have to disagree a little there Acko. Sito+ aren't actually that bad. I understand where your coming from but if he already has the kit it will work pretty well.
Upgearing with the clutch cog is a good idea.
If he's just had a std barrel before just bolting on the malossi will make a huge difference. Be careful drilling the filter regards jetting. Suggest 112 but may need smaller. Back the timing off as well.

cheers, what size cog on the clutch m8, air filter already been drilled just a cock hair on the timing needed?

[Diablo]

Whilst its all new I'd retard it a fair bit untill you know the jetting is safe. It will definitely pull 21 but may pull a 22 with a sito+
