You can relax about the junk in the oil filter. It is normal to find metal shavings, sealant particles, rodents and reptiles in your oil filter on the initial oil change or two. If you want to really freak out, take a look at what gets collected at the oil screen some day.

The "pop-pop" on decel is from a too lean of a factory carburetor setting from the factory. It is simple to adjust, and you tackle it yourself. It is simple to do, can be done without removing the carburetor. It involves removing an aluminum plug and backing a setting screw out two revolutions from the "all the way in" position.

I can post up a how-to if you are interested. This process is one step of a popular modification nicknamed "The 22 cent mod". Other steps include shimming a needle and enlarging a slide hole with a drill bit. These efforts will give you a tremendous increase in throttle response. Like unleashing another ten horse power on that mean machine.

You can poll the members here and not find three that agree on exhaust modifications. Personally, I do not find enough gain for cash outlay with after market exhaust. There are some dyno tests out there that indicate one or two exhausts will chart higher horsepower readings. My own personal bike does not see RPM's that exceed the 52 to 5500 RPM range, and I think some of these dyno tests are showing most gains from after market exhaust in the higher RPM ranges. If slipping on an exhaust would gain all KLR's a four horse increase from an idle to top operating RPM's, there would be an immediate stampede of KLR riders to the parts distributor houses.

These are only my personal opinions. While up on this soapbox, I'll throw in that with current regulations regarding motorcycle exhaust, and the tunnel vision focus of activist groups on us, I would resist laying out any money for after market exhaust at the present. Unless you have enough additional cash to cover federal violations charges that may include impoundments, depending on where you get hooked. I would suggest tinkering with what you have and seeing if you don't find some suitable settings that keep you out of trouble with the law.

Hopefully Tom will pipe in on this one, as he has more experience with the GEN II exhaust systems than I do. He is a self proclaimed non-conformist when it comes to regulations and exhaust.

Do a search for the 22 cent Mod. It will feel like a different bike.

Decel popping could come from an air leak on the exhaust side. Check the cylinder to head pipe bolts and the muffler to head pipe bolt.

I'm the forum's loud bike crank (disclaimer!) - making the bike louder doesn't do very much for it's performance but does antagonize the non-riding public. Any aftermarket muffler will be louder than stock and will get louder unless it's repacked reguarlly.

As everyone above has pointed out, there are no real performance gains to be had with an after market exhaust. The only really legitimate reason for dumping the stock exhaust would be to reduce weight. As Spec points out, that's going to come with noise. As vatrader points out, it going to cost money. Unless you get your money for nothing and you're chicks for free, spend your money elsewhere or you'll find yourself in dire straits...

The 22 cent mod will take care of the decel lean pop. If you want to drag 90% of the avaialable performance out of the KLR, consider a KLX needle. That and a jet will run you $30.
