If you click HERE you'll see that all of the Z50 softtail models used the same fork spring. You should be able to use the Fast 50's HD springs (if not the complete kit) with no issues at all
I would like to see someone like "Torque Test Channel" on Youtube see if there's really any difference in strength between the Chinese inverted forks and the OEM forks.Also look at this discussion.
Z50r aftermarket forks - USD forks or conventional style...Working on my second Z50r ... firstly, updating the forks (and the rear of course to match) but will be using the aftermarket Chinese forks that appear everywhere on Ebay with the disk brake setups. There are the usual 2 options - extended conventional forks & extended USD forks: Wondering...www.planetminis.com
Dan, the guy working on the bike, did buy a rebuild kit for the carb, but chose to stick an aftermarket carb on it to get it running. I think he said he had more money in the rebuild kit than he did for the "substitute" carb.You should be SURE to keep the original carb.
Thanks! I'm sure that there are some who think I am nuts for not just doing a "restoration" of the little bike. I think the plans that I have won't take away the character. If I were swapping the forks, putting an aluminum 10cm swing arm, and swapping a 140cc pit bike motor, a custom paint job, and a drag pipe on it, then I would also think I am nuts, too.Digging what your'e doing. Looks like a great bike to start w/. Keep posting up what you are doing. We all like pictures. Like the cars too.
LOL! That's why I put the NERD ALERT notice at the top of that post.NERD ALERT --- uhhh lost me with all the math. I too wasn't numbers oriented either. Post pics up when "shock extensions" arrive - curious as to what you're doing.
