More roar less power

My last few rides Ive noticed more chug type roar like when taking off and lugging the motor but now its doing it up to 3000 RPM.
Its a 94 with 33k kms.
Seems to be down on power too.
Its always had oil,I change every 1000-1500 kms. header bolts are tight too.
any ideas?

clutch?

thx

I was going to say check header bolts. Clutch is usually easy to feel. Get up to speed with ease and see if it feels and sounds normal. Then get it to speed by cracking the throttle. It should feel down on power and you should kind of hear it whine.

Seriously, do you have a mouse nest in your air filter box?
I've seen them completely full of dog food or grain!
Or worse yet, chewed thru and sucking dirt!
Take the air filter OUT and look at the back side.

I had the same problem with my 93' (2005 engine), I decided to crack open the case and inspect the balancer system. My bike developed this slight ticking, lost power, erratic idling and very viby. I found the stock doohickey was in tact but the spring had lost tension causing slack in balancer system. I ordered a Eagle Mike Doohickey with torsion spring and installed it last night.

Problem solved, bike feels brand new and is very buttery smooth.
have you inspected/adjusted your doohickey lately?

The stock muffler will rust out eventually and it also contains fiberglass packing that will break apart and fly away. The muffler is about half stainless, but the other half rusts.

Depending on which parts of a muffler rust or change position, the engine can run leaner or richer. Louder or more muffled. Blocked at some RPM and resonant (freer) at other RPM.
