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...

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.

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

It doesnt have to be badly engineered or dangerous! Honda and the other big manufacturers used to do it. Not sure if they still do.

Cheers
