Mmm, yeah I don't have much to say on the technical side of grade and ° on those hills, other than if those hold the records they clearly haven't been to my side of the world.
These are all roads, even cars struggle to keep 2nd gear and are luck to make it half way up in 3rd if they got enough speed before hitting these hills.
The point I'm trying to make is, she ran ok up most of them with the bigger 52 tooth sprocket and I only needed to pedal assist up some of them to keep her at or above 25km/h. Now not so much, I'm peddling up smaller hills to keep the speed up, and on the larger hills she looses to much speed and stall out while I'm trying to keep going at like 3km/h
Frogslayer mentioned the jetting. That sounds like it could have caused it and a easy fix, the problem is that she will still be clogged up, so guess I need to replace rings and exhaust as well.
Any one know of anything I can use to try clean out the exhaust?
And what else could affect compression? The cylinder housing and and piston seem fine, I see no scuffing or scratching on either. I did have alot of issues with the clutch slipping but have managed to sort that out by adjusting the spring on the clutch shaft, after replacing the bucking bar, ball etc.
I'm not sure where your side of the world is? I live in Tennessee and around the steepest paved hills I know of here is some driveways that reach a 40% grade which is 18°. Here in the mountains we do have some paved streets that reach a 30% grade which is 13.5°. A 45° hill is a 100% grade. Degrees to gradient is: D° x 20/9; gradient to degrees is G% × 9/20.
Here's a video on some of the steepest streets in the world.
It isn't my intention to be insulting but rather teach you how to accurately describe slopes. There are several inexpensive inclinometers one could put on their bikes. You can also get bicycle computers with them on it and there's apps you can down load onto your cellphone.
