does anyone use some sort of high heat silicon to the area where the muffler connects to the header(torca clamp)? im thinking about doing this to maybe help with some air leaks and popping on decel!! | ||

I do. | ||

I think it's called RTV. It's what I used, and it worked great. Make sure your header pipe and inside of the muffler where they mate are as clean as you can get them. | ||

i use some header goop on mine. | ||

Hi-temp permatex copper rtv sealant....yup | ||
| Ragnagwar |
Permatex "Ultra Copper" comes in a you guessed it, copper colored tube. Good stuff. | ||

Make sure you get "Sensor Safe" | ||

+1 for the copper RTV. | ||

Hey, Spidey, does it really matter since it's going way after the O2 sensor? Better safe than sorry I'm sure, but I'm curious. | ||
| Spiderman |
well i would love to tell you no it doesn't, but the fumes get trapped in that header and rise and collect. Sometimes it will burn out sensors, other times it won't. I am not sure the particulars. But on a XB I sure wouldn't take that chance, a O2 sensor isn't a 10 min job like it is on a tuber  | ||

Point well taken. No it ain't a ten minute job. Even if engine rotation at the Barn is getting faster and faster. Like I said, better safe than sorry. | ||

Do they make the "sensor safe" ULtra Copper? or is Sensor safe a different brand? Its been 10 yrs since ive have to work on anything that needed this stuff so im kinda behind again! NEVERMIND, I JUST LOOKED IT UP!! THEY DO MAKE THE ULTRA COPPER THAT IS SENSOR SAFE!!!! (Message edited by americanmadexb on April 09, 2007) | ||

Read the label and just look for "safe for oxygen sensors" most anyone selling RTV will list weather or not it'll be safe or not. | ||

Hey will an occasional deacceleration pop or two hurt anything? I had a rash of this issue when I first put on my race can. Revisiting the torque on the clamp bolt solved 90% of it, but I do still get an occasional pop or two. | ||

I don't use sealer on that joint anymore with my tube framed bikes as there really isn't much exhaust gas that escapes out between these two pipes...neglible. I don't believe it would prevent popping on decel either...that sounds more like a lean condition, or that the spark plugs are fouling. Everytime I need to pull the plug on my primary to drain the oil, I have to take the muffler loose some so that it will pivot downward at that joint, so it really doesn't make much sense for me to seal it. Sealer also make it a real bitch to get the muffler off of the header. jimidan | ||

I'm with jimidan, no sealer needed or wanted on my S3.... | ||
| Mrs_glitch |
If the popping is caused by a small leak at the muffler joint (mine was) it will cause no harm. If it's caused by a lean condition that is a problem. | ||

When did you get your own bike Ann? I need to get back down there for some torture loaf!! | ||

best material i've found for the job is furnace cement, comes in caulk-gun tubes. you can also simply purchase qualco exhaust cement at your favourite auto parts retailer. I'm with jimi, though, in that my frequent oil changes neccesitate frequent muffler R&R. I know of many buellers, however, who simply 'dent' the top of their muffler so as to make oil changes possible w/muffler intact. ...for the record,though, exhaust leaks will and do cause popping on decel...(this from my BMW service training) ...and that popping sound means some degree of power loss. | ||

Thanks for the deacceleration pop tips. I am running the full race kit, recent TPS reset, timing is spot on, NGK Iridium plugs, 8mm race wires, open airbox conversion, breather re-route. It pulls like a freight train and does not foul plugs. I simply get a pop or two every once in a while when engine braking from high RPMs. I assumed this was normal. I also did notice a major improvement when I tightened the muffler clamp up where it meets the headers. What do you guys think? I like your tattoo by the way Ann. Thanks for your thoughts. | ||

Back in the day of the tubers, Buell used this on all the production bikes. I've used the same thing on my S2 everytime. 1313  (Message edited by 1313 on April 15, 2007) | ||

Is there a recommended mileage to replace the O2 sensor? What's the approximate cost of an O2 sensor? | ||
| Kowpow225 |
20 bucks at auto zone. Bosch part no. 12014 1 hr job at a relaxed pace. You'll also need a crows foot. 21(?) mm I believe. | ||
