If you blocked it, you'd get the same quiet sound. Hot exhaust was escaping through the small tube, where oxygen is supposed to be introduced, hence the noise.

I think I will leave it as is for now--sounding quiet AND saving the environment

Been busy lately but I did get several things done that I need to post about. Have some good pictures to show the valve adjustments, some sprocket tests, chain link removals, hand guards, and speedo indicator failure repair. Anyway just checking in and hope to get it posted soon.

Thinking about the Trail Tech Vapor to replace the crap instruments that are stock.

Just picked one up today. Has a few things that need sorting but I am happy overall. Did 70 miles today about 10 of those off road.

Good for you; you got the bike dirty on the first day.

Thanks for the pic, iTrack. I like those bikes; they look to be well-built.

Thanks for the comments. I need to get back on here, I have been side tracked by a CX500 café racer build. I lost the pictures for some of the mods but can post what I still have. The speedo dial just fell off one day while I was riding so I had to tear the thing apart to super glue it back on.

Here is what it looks like to do a valve adjustment, you need to pull the tank, seat, valve cover, and timming inspection cap/cover. The feeler gauge tool shown is the type that I like to use. It is a Motion Pro Tappet Feeler Gauge. Ebay has them for ~$4.

Valve adjustment is done at TDC. Rotate the engine until the T mark is aligned in the inspection hole. The head of a deck screw that needs the square bit works well to adjust the tappet with precision.

Carb reference photos. After the removal of the EPA smog crap and catalytic converter I needed to rejet my carb. Here is a breakout of the carb in pictures. I have a numbered drill set to #60 and a micro numbered drill set to #80. Like these:

You can use a drill to jet chart like this to get your tuning adjusted.

Please start a thread on that! Plenty of CX fans around here, and also several café nuts.

Nice TMEC! I got to check-out my first TMEC the other day... a Denali xt version... for sale locally.

I was impressed with the bike overall. It was a 2013 model... with only 780 miles. The huge Denali 200XT decals aren't just stickers though. They seem like there bonded or clear-coated over on the plastics. I love the rear rack. The seat seemed to squish me into the tank. If this had the larger 230cc engine... I'd be in my garage. Seller's price was too high. Gonna wait for a Hawk 250.

Cheers!

Great pictorials!

What drill bit sizes did you end up with using on your carb?

Is that mixture screw assessable only by removing the carb bowl?

Nice handguards. Where did you get them?
