Nuthin' wrong with the Cyclops.....a hard tire too beat in every way (price, performance and looks). I like them as much as the hookworms now and you can't get the hookies in 24" anymore...

I got bored last night and decided to take some measurements of my bike as it is:
wheelbase measurement 42"
front height at handlebars 38"
rear height at seat 33"
total length of bike front edge of front to edge of rear wheel 64"

put on a new fred engine sunday with the enlarged phbg plenum for the 21 mm carb and snake pipe 6cc chamber head
running a little on the hotter side at higher rpms 292 F higher than its been getting ,
i have a 76 main jet and a 45 idle jet clip in bottom position and mixture screw pretty well out.
running 87 octane and maxima 927 32 to 1
seeing what this new balanced engine does after break in

today on a long flat i was winding out 8700 rpms and~ 39.0 mph after the engine got hot. it 4 strokes hard until it gets up to about 200 degrees then it really pulls hard. I still am not sure how my performance is stacking up to other higher modified engines.
I need to take some links out of my pedal chain. Right now I have to pedal up to about 15 to really shoot off into the powerband. i cant apply full force without skipping or jumping teeth, a product of running a derailer on a single speed freewheel 20. it runs good if i put on the 7 speed but cant get the hammer down on this single speed freewheel. If i were more dedicated id probably space out and just put bmx 25x9 gearing on. Not much luck getting straight chainlines for me. Don't know what my problem is

messing with my case saver today. measured the aluminium, it is .25 thick.
I had tried with lesser skills to drill holes to mount it about 2 years ago and i ended up drilling 3 holes (one extra) to get it to mount, then i always had slight pedal clearance issues with the case where the nuts stuck out on the outside of the clutch arm cover. well i filled those holes with a weld and i am going to try to drill and tap the hole so i don't have a nut or bolt sticking out where my pedals can hit.
Noticed when welding the cast case that all kinds of lovely stuff came up to the surface.

With a regular sized rim on the back 8700 rpm should get you alot faster than 39 mph, I just did 46.9 with my new 26" build with a fred head, fred jug, and fred piston on a gt5 bottom end.
Ok but you still need to gear accordingly, and 39mph at 8700 rpm is probably not going to work, maybe you would need a 32 tooth sprocket- or just put on a 26" rim
also that article is talking about normal pedal bikes and we are ultimately talking about gear ratio's and engine rpm's so in that aspect smaller would be slower.
ive got a 28 t sprocket. i havent put it on yet. I'm not worried about putting 26" rims on, i like having a short wheelbase and low CoG.
broke another mounting stud in the front of the motor flush with the case. going ot get a left hand drill bit and or a ex-3 extractor hansen will take pictures later, replacing everything with socket head caps screws, tired of dealing with this stuff. Loctite blue too.

fork mounted bars. thinking that and a lower seat will get me in a more comfortable lower riding position
also should look pretty cool

had ordered bikebobbers mounts for my engine after having trouble breaking engine mounts on 4 different occasions ready to see if those make a difference in smoothness
i would not rubber mount bars, for after sometime the rubber will give then who knows what or how the front end will bite.
