Hard to See Trees in Forest Sometimes

[grog]

When i first got 14, can had end baffle. Of course i drilled rivet out and removed it, i like a noisy bike. So, forever its sounded nice but always a bit of a whistle, rev, back off. Ive always wondered why the whistle, just thought thats how it is.PAIRS blocked, nice free flow exhaust. Just how it is. Today bike sitting, warming up, Mate said, has a bit of a whistle sometimes. Told him ive no idea, tried to fix it for a decade. He put his finger over hole where rivet came out. Such a different sounding bike, amazing. Im gob smacked i missed that. Fitted a rivet, rode home. Like a different bike. I really cant believe i didnt think of that, a bloody 1/4 inch hole. Sounds superb now.

Like a mini pan pipe @grog

Drill lots of different size holes then see what tunes you can play @ various rpm....

[Eric GSX1400K3]

What about covering the big hole and using the small hole as the exhaust?  Might make it sound even better...

Thanks for replies Gentlemen, very good stuff. Im just glad the whistle gone. Strangest part, fitting Tri Oval tomorrow.

That's piss funny

Even with the Tri Oval fitted if you remove the baffle and don't put a bolt or rivet back in the hole you will hear another noise just not a whistle

I gave the Yoshi a trial run today. Should post pic to make sure i had it right way on. 😂 I did build a motor once, forgot to fit oil pickup.

Easy mistake Grog

Is that why  you only did  it once?

[grog]

Hate to think how many others ive built Eric. That one and a V8 Holden are only stuff ups from memory. Holden i timed wrong, dots on chain on wrong side of sprockets. Not bad i reckon, 50 yrs next yr fixing bloody cars.
