I've been noticing a mechanical rattle from the engine when I'm between 2-2.3k revs, It mostly occurs when I'm going up a slight hill. Does not occur on flat surfaces usually. Also doesn't matter what gear I'm in. It just has to be on a slight load up a hill and at 2-2.3k and makes a rattle from the engine.
It's not a consistent frequency rattle either
Didn't noticed this before upgrades and tune.
Upgrades:
Silicone inlet
Invidia Dump Pipe
MSR Tune
Mike from MSR suggested that it could just be the thinner dump pipe, so more sounds can be heard easily from the engine.
Anyone else have any similar occurrence. Or know what it might be.
