Pampera 450 Misses at 3000-4500 rpm

[Gassy Grech]

Hi guys

I live in Australia and recently took owenership of a clean, low kms, Pampera 450. The bike is great condition apart from one major issue.

The bike runs chronically bad in the 3000-4500 rev range. It runs a Dellorto PHF36.

One repairer first claimed a dodgy ignition coil and then claimed to have cleaned out the carb, but when I got the bike back it ran worse.

Any ideas or advice would be GREATLY appreciated. I am reasonable on the tools and am contemplating taking the carb apart myself.

kind regards,

Tim Grech.
