My Bike Is Broken

[atomichurley]

I was riding my bike today it has a Zbox 2 stroke 66cc engine i came up to a large hill so i pulled my clutch in and rolled down the hill when i got the the bottom of the hill i let the clutch back out i obviously was going to fast my clutch cable snapped and the bike while skidding 20m the rear tire popped.
I will be replacing the rear tire and the clutch cable. Does anyone have any advice when coming down hills regarding the clutch?

best advice is to not let it freewheel and overspeed. Leave the clutch out and let it reach max engine speed and hold there. My good friend was killed on a motorcycle just like that. Pulled the clutch, freewheeled down a hill, popped it out in too low of a gear at the bottom It slid over, throwing him into oncoming taffiic.

Although I don't know if it is good for the engine or not, while applying brakes, clutch engaged I hold the kill switch in while coming down a hill. I use the engine as a secondary brake.

I pull my clutch in for down hills too, but you need to wait until you're back down to a pretty slow pace before letting the clutch back out. A speedo helps, otherwise it's hard to judge sometimes. It pays to give the throttle a blip at the same time, to bring the revs up to match your speed. Like when changing down a gear on a motorcycle.

(Mine's also a ZBox 66cc.)

What are you looking for in a ride? Rigid? Suspension(Prob)? Schwinn 88 Rocket? I think?

With the ignition off, and clutch still engaged - the engine will still be drawing fuel but not burning it. The raw fuel/oil mix has about the same lubricity as raw gas, and will wash the lube off of the cylinder walls, bearings, etc.

When I go down a long hill, I pull the clutch in and let it idle and use the brakes to keep the speed within reason. I know I could just let it coast and hit amazing speeds, but I would hate to have a tire blowout (or a clutch cable snap) going so fast. When I hit the bottom of the hill, I hit the throttle and engage the clutch - matching the RPM's as described above.

Dont forget the possibility of shock cooling the engine. If it is a steep hill and you get going real fast, and the engine is at idle, or has the kill switch engaged, you just might crack a cylinder.

Whe coasting down a hill, pull in the clutch and let it idle, when you reach the bottom wait til you are doing around 10mph or so and slowy release the clutch while giving it a little throttle to pick up some speed.

Wasn't that hard just to give the correct answer, i dont know where the other crazy ideas come from.
