The front (small) sprocket on my Challenger is worn with "shark fin" teeth. I can't seem to find any posts that detail a rebuild or fix for this. Anyone tackled this project who is willing to share their experience? Thanks in advance.
Can anyone tell me the dimensions of the two roller bearings that support the steering stem????? Mine are mangled beyond repair and I can't seem to come up with anything on Ebay that matches my measurements. Thanks.
I see Carlisle has a 2 and 4 ply tire that should fit this machine. Does anyone have experience with the 4 ply? Original worn out Generals seem to be a really stiff sidewall, and I was thinking the 4 ply would be a better choice for stability and flat prevention. What are your thoughts? Thanks.
