Hi Guys,

 

Im Kyle, live in Newcastle and bought my first bike last year a 2007 yamaha YBR 125. I love this bike and its been really reliable so far. the bike had been neglected after a friend had a accident ( not bike related ) and was unable to ride it for sometime so it had just been sitting outside. we live by the coast and i guess the salt air had been eating away at it. i pretty much stripped the bike down and sanded all the rust off, primed and sprayed the frame, wheels and forks and it looks great. Problem i had was with the exhaust. i did sand this back as much as possible filled a small hole and then sprayed with exhaust paint. All was fine but the repair as expected didn't last long. 

 

Now for the problem, i bought an after market exhaust however it does not have the pipe coming from it that attached to the air box like the original did. i have been told that you dont need it and you can blank this off at the air box? how would you do this? any help would be great.

 

Thanks

Kyle

Hi

Glad you are enjoying your bike,

I don’t know the diameter of the pipe you are talking about or what material it’s made from,

But a good method for blanking off smaller diameter rubber type hoses is to slide a bolt with a shaft the same size as the inner diameter of the pipe into the end so that the head of the bolt will stop it from sliding all the way in and secure it with a small jubilee type clip or a zip tie,

I don’t know what this pipe is or what it is for, I can only assume it’s a pipe used to convey warm air to the air box to try to offset possible carb icing problems.

its just for hydrocarbon emissions, so that any unburned fuel is offered air from the airbox which helps to consume it (I think)

 

there must be very many ways you could find to blank off that hose spigot
