Hi All,

My Scram 411 (high flow air filter, fuelex, tec camshaft) has a very irritating harsh noise under moderate to hard acceleration. It had this prior to the tec camshaft going in.  I believe this is combustion noise and may well not be harmful but it is horrible and I would like clean acceleration through to the rev limiter without this -  not that I would accelerate like that very often if ever!

Is there a cure?

Cheers
Frog

It would be a great help if you could somehow record it.

It would be hard to get a decent recording but I'll try. If anyone has had or still has the issue they'd know immediately what I'm on about I think.
