Safe way to check for exhaust leaks
06/29/16 at 09:36:19

(neat idea I stole form this car guy)

1) MAKE SURE THE EXHAUST IS COLD
2) Set vacuum from "suck" to "blow"
3) Connect to muffler
4) Hold a candle or grill lighter around the connection points and look for flame getting blown around

Think there is any negative impact to the Savage, such as junk getting blown back into the cylinder?

Before you do this.....put the bike in gear and slowly push the bike forward until you feel the piston come to the compression stroke - then the valves will be closed and nothing will blow past the exhaust valve.

I remember reading a story about a fellow in the Corvair Club that wanted to siphon the fuel out of his car - but he didn't want to put his mouth on the siphon hose and get a mouth full of gasoline. So he got the bright idea of using his vacuum cleaner to get the siphon action started....then he could quickly shove the end of the siphon hose into his fuel can. The problem was that when the fuel came out the siphon hose and mixed with the air in the vacuum cleaner hose.....it became a fuel/air mix that traveled into the vacuum cleaner - and it found a spark or two in the electric motor...."BOOM"! The fellow wanted to warn his other club member about it so they wouldn't do the same thing - but the reverse actually happened. The member started blowing up vacuum cleaners on purpose.....and even had contests at their club gatherings.

Sorry to have distracted the thread with my Corvair Club anticst....I actually like the idea of using the vacuum. When you are running the engine to look for leaks.....things get noisy and hot and it is easy to get burned.

Trouble is I can see folks heading all kinds of directions with this. No telling where they may end up. Daves addition to the initial instruction is helpful too; in all seriousness.

Sorry Dave, I have to play Devil's Advocate. Anyone with half a brain knows to not touch a hot exhaust pipe.

Re: Safe way to check for exhaust leaks Reply #9 - 07/01/16 at 03:17:59 Yes, everyone Knows not to touch a hot exhaust. Checking for exhaust system Leaks means working close To the exhaust system, and the connections that need checked aren't exactly easy to get close to and maintain a safe distance From.. Everyone Knows the knife is sharp, too.. And they get cut anyway.

I don't like working around hot chrome pipes. I have had 3 pretty serious burns from chrome exhaust pipes....one of them took months to heal and left a scar on my calf for about 10 years. I still have a faint scar on my arm from a Suzuki GS550 when I worked at a dealer and was changing oil in a customers bike.....in 1976!
