Is it a speedo like this one on my bike?

I love the thing, very easy to read and looks cool, but accuracy is not it's strong point.

They have a little bounce and accuracy depends on your tire size.
I have a couple of digital speedos you program the exact circumference in centimeters of your tire at the time I should hook up too to see how accurate it is just for giggles and grins.

Regardless, they are a cool cheap way to gauge speed, nice purchase Kat.
My usual riding speed is 35 on bigger roads but I can take her to the red zone if I bend down and tuck in ;-}

[B][Idle cold... I wish . Mine wont idle at all , my top speed is 27 mph and I get as lot of sputtering and herkey jerkey getting up to speed when she is cold or even close to warm as she heats up it doesn't ride as rough but I can tell something just isnt right after all the video's Ive seen I know what a good motor is supposed to sound like & I'm not quite there yet.I'm open for advise I have a 66 CC motor NGK BP7HS plug gaped at .029 "seems rather close if you ask me" an NTTN carb and a boat load of patience /B]

If you remove the head gasket and try to use the red stuff only it will increase the compression ratio, but good luck with the red stuff working in the long run.

Read Al.Fisherman's post #4 for the best thing one can do for head gasket issues.

I just read that thread, lots of good info thanks! I think I might just leave the metal gasket as is, it's running strong with good compression now and I don't want to mess it up!

once warm...but still sputtering...does it even out for a short run if you turn the gas petcock off and pin the throttle open?

If your engine won't idle it sounds like you need a carb clean or you have an air leak somewhere. My engine had a hard time idling and turns out I had an air leak on the base head gasket which I replace with red gasket making. My engine idles good now.

Today I did nothing with the Atlas as yesterday when I removed the front forks I found out that a PO had abused the fork stem nuts and stripped the fork stem threads. The nuts are fine though. It really sucked as I all ready made up a jig roughly copied from Sheldon Brown's (RIP) help site to have some linear caliper lugs braised onto said forks. Salvaged the lugs from a garage sale mountain bike carcass and filed them to fit perfectly too.

Toady I got lucky though and picked up a brand new Point Beach for a song.
Now I am saving up for a EZM kit to stuff into it.

I think your right I took the carb and offset off last night & found a blown gasket so I hammered out a new one with my trusty ball peen I ended up forming it to the head after I used the offset first then found it "the gasket" to be restricting the tapered part on the head I will be test running it in a few minutes & will report bACK

WELL just took a quick 4 mile run 2 out & 2 back & acceleration has increased i'd guess at least 25% top end isn't much better 30.4 mph top speed ever. I get that perfect purr where it all seems to be perfect but then .. in less than a minute it goes through this rattling / vibration stage and I can feel it slowing down almost as if it is the spark. It's not cutting out completely but decreasing in voltage or perhaps it is a fuel issue but I don't have any bubbles in my fuel line what so ever and the over sized fuel filter is always full.......Scratching my head...... I keep getting a taste of how it should be running all the time , do these have a governor because that's what it feels like?

I did this, and it pretty much runs the same just cuts out as the fuel gets used up are you thinking I'm flooding out? I use to have a dark black wet spark plug when i pulled it out however I raised the clip up one notch which tech. would be lowering the needle itself into the carb correct? and now my plug is dry and minimal carbon build up on plug . Still no idle. Thank you Wm Holden
