I installed a Super Trapp muffler on my M2 the other day,I got off e-bay. It came with 15 disk, the end cap has about a 3/8 hole in the center of it. I am wondering if the guy I got it from drilled that hole there himself of does anyone know if that end cap is totally closed? I plugged the hole with a bolt and a couple washers. It seems like it runs better with the hole plugged. Since my carb is not jetted . Thanks... | ||

Stjac; IIrc there is a "factory" holed cap I think that the hole is larger, the hole defeats the purpose of the rings, unless your building a race bike, My 0.02$ ping AL monday get a replacement "solid cap" adjust by adding rings. | ||

The small hole is too small to worry about. I would leave it there. I put one in my solid cap on my White Bros 2-1 on the Sporty too. It is there so that an AFR meter can be properly placed in the pipe on a Dyno. Without the hole, the AFR meter cannot be placed inside the pipe like it's supposed to and makes it difficult, if not impossible to properly use the dyno with that pipe. As a matter of fact, I know of at least one bike shop that keeps a spare supertrapp endcap at the shop with the hole in it so they can use it to tune people's bikes without drilling the customer's cap. That particular shop didn't have an endcap for a White Bros pipe though, so I was obliged to let them drill mine so the XL could be dyno tuned. | ||

If nothing else, it adds to the performance fluff factor. Leave it there for people to ask about it, then tell them it's there so that the bike can be dynoed properly, and leave them with the assumption that the bike has been heavily moddified and tuned  . | ||

Cool... Thanks for the info... I noticed since I plugged the hole its not as loud and doesn't pop as much when I left off the throttle. But it still runs and sounds better then it did with the stock muffler... Looks better too... |
