I need to ride my bike about 15 minutes down the street, but it doesn't have a front exhaust pipe at the moment. I'm riding it to the place to get it fixed.

Is it going to hurt it if I do this?

 

[andyauger]

No. It should be fine, but don't make a habit of it. It will be super loud and annoying.

i couldn't imagine it being much different than no exhaust on a car.

my car's exhaust is only hanging on by a metal coat hanger - in other words, no exhaust from the cat back. i get worse mpg and some fumes.

one day it will get fixed

Do you mean the front header isn't on the bike?

 

[dan46n2]

no header?
I personally wouldnt do it.

 

[superwormy]

I mean the short piece of pipe that connects to the front cylinder is *on*, but *loose* because the f'ing bolts that hold it against the engine broke off. And now I get to bring it to the shop to have the bolts extracted.

 

[superwormy]

Sooo... can I get a verdict on this? It's a 15 minute ride...

Fork over the money and have it towed.

15 minutes is a LONG phucking time for fresh O2 to be pulled in through the gap between the header and the head to the exhaust valves.

You just might burn them up, then spend hundreds more to replace them when $50 would tow your bike.

+1 on what Brad said.

Running anything without an exhaust manifold or header will cause you to float a valve.

[davis]

yea.. no header isn't good. i didn't realize that's what you meant

 

[Trambo]

Surely you have a friend, neighbor, co-worker or family member that owns a truck or trailer?? You can even rent a pickup from U-Haul for like $20 bucks for the day.

LOL, did you just make this up? Let me guess he is going to bend a valve because of the cold fresh air hitting his hot valve!!!!

O.P.

No, its not good for you motor, in fact its relativly bad, but dont listen to the guys telling you its going to bend a valve or "float" a valve. In all reality the chances of real damage occuring if you are very careful (low rpm, low idle, low load) are pretty minimal, however as others have stated if your asking the question than you are worried, and a buddy and a pick up truck are cheap insurance for your bike and your piece of mind.

 

[zaneykiller]

i dont know if this helps you or not but i have a 3 wheeler that hasnt had exhaust since the late 80s still runs fine

Buy a screw extractor and you wont have to move your bike.

2 stroke?

 

[zaneykiller]

nope its a four stroke.

 

[benprobst]

nope its a four stroke.

yeah ive seen similar, though they normally have pretty bad valve burn by that point. but hell its a three wooler, just ride it and try not to kill yourself!!!

 

[stinky_finger]

It probably won't hurt your engine for a few blocks , but it is going to hurt your ears and your wallet if you get pulled over!

 

[dunelly]

try extracting the screw yourself? most kits can do it for $5
