SBP freewheel problem? Look in here!!!

if that were true, then the sbp freewheel shouldnt say anything about the use of a slant head or 66cc or above motor, it should have weight restrictions as i was just pedaling when it happened.

Huh? There is no force on the pawls when you are running under engine power. Only when starting/riding.

Think of an engine with 5:1 compression ratio. Turns over super easy, not much force on pawls. Now think of a monster engine with 13:1 compression ratio. Mega force on pawls. No low cost FW can handle this and they snap. If you were just pedaling and not starting the engine, then use the warranty - typically our new standard FW can handle that.

Ohhhh.. I understand it now pablo, my mistake. I'm still fairly new to this whole shift kit thing, but im learning as I go along. So far with the 4 pawl mechanism it's been running fine. The only other problem i've had is the axle? Can't think of the correct term for it.. its the part that holds the crank arms, but I believe mine is bent. Anyone know where to get another higher quality one?
 
Yes a pull starter will eliminate the need to use the freewheel to pedal start the engine but by the time you buy it, install it, pray it actually works, then realize you need a wider bottom bracket so the cranks will clear you could have bought an HD freewheel and been done with it.

Oh and on the comment on the spindle, they usually aren't bent but possible. Most likely what your are seeing, if you are detecting a wobble, is the crank arm not mounting perfectly square to the shaft. This is very common with square taper crank assemblies and why they created the ISIS splined systems.

I agree.
 
If you are having problems like i've had with the pawls of the freewheel breaking on your shift kit, then I have a solution for you!!!

But the proper solution is a proper freewheel, as the standard lower specification freewheels are a complete waste of time, as they don't hold their mechanical tolerances very well, and that's from brand new - you get what you pay for - it's that simple.

I have advised everyone who is thinking of purchasing a Shift Kit to bit the bullet and order the Deluxe version because it comes with the White Industries Heavy Duty Freewheel system, not to mention all of the necessary tools to service the drive train.
My White Industries Freewheel body has survived over 50,000 kilometers (31,000 miles) of use; many of those kilometers under punishing conditions.

Please read the bottom post in this thread for an explanation of the the benefits and design of the White Industries freewheel, and why it is the "ONLY" freewheel to be considered for a motorized bicycle application.

I can typically get 6,000 kilometers (3,700 miles) out of a 67082RS bearing, but now change the bearing at around the 4,000 kilometer mark (2,500 miles) to guarantee a high level of bearing shell stability and 100% bearing reliability.
