Pwk 28mm vs pwk 33mm performance on 421 assassin LP


Recommended Posts

I have a 4 mil,421 driveline assassin low port setup with stock carbs. Thinking if it makes sense to port them for a little more power, which ever route I go, I absolutely need to keep my bottom end power, love it when the bike is really snappy. I really appreciate the input, which one will keep it snappy? Especially if ported or left as is?

My 421 was an Assassin LP with 33mm.

Ask for a nice "clean port", match you cases, good reed valves and go with slp pipes and 28mm.

That will be a good "trail friendly" engine.

Dunno if 33mm would be a big difference for trail, but it will drink more fuel for sure.
