Things to learn...

After several days of having the new air filter on, I put on a new front sprocket. I took off the front snap ring and decided that it was garbage and that I'd have to buy a new one. Now you can go the easy way and buy one online, well I went the long but shorter route(if that makes sense) and drove to the hardware store. Somehow I never really thought how hard finding a 16mmx1 snap ring was going to be... I ended up going to 3 hardware stores, 2 box stores, and a partridge in a.... in the end just let your fingers do the walking and phone places.

So after the installation of the front sprocket, with the new snap ring, it seemed a little wiggly. After reading online that it was normal in 1 post, I was off! Moped Mondays at Founders, where everyone was running late so I decided to go for a ride. Well after probably riding 20 or so miles, the new sprocket decided it didn't want to be attached to my bike and kindly went and hid somewhere. So luckily I was 1/4 of the mile from the GRGR shop and rode my moped on the sidewalk like a bike. I soon asked on MA forums and the answer I received was a "snap rings have a rough and smooth side" take a look at one, like all sheet metal, its smooth on either side, if I go across that posting I'm going to call BS on it.

Anyway not a whole lot of riding, though the short time I did ride with the new 17t sprocket, it was noticeably faster! Going up hills was just a wee bit slower but who cares?

Right now I have a new rear sprocket and will keep my original 15t sprocket on. So it'll be gear at 15:42 instead of 15:45, only problem is the pedal chain is too short and will require some lengthening due to the fact that it limits the drive chains length as well due to the rear wheel is limiting the whole thing.

The Gooch will ride again!

Moped Problems Fixed

Found out why my moped was running on the slow side, it was due to air leaks in the carb. I was able to remedy this by putting new gaskets in the Bing carburetor and there was a noticeable difference in the performance. My guess is the leak started when I replaced the my jet for the second time after figuring out that I had jetted it to high. I also think my speedo is way off and just got worse so I really need another means of figuring out my speed and on top of that the engine doesn't like to run in hot and humid weather.

I did tho put on a new high flow air filter after I got the moped tuned and after the install it runs like a champ. One guy that rides every Monday, on a similar moped, with a better cylinder, a 28mm pipe that looks stock, and a 18t front sprocket was riding and I was able to out perform him where before he would usually out run me when he reached his moped's top end.

As it stands now, my moped has plenty of bottom end, I probably will do a sprocket install tonight and with a little luck I'll have a higher top end and will hopefully cruise a whole lot faster.
