Cheap CT forks!!!

One of the bummers about an old CT is that the forks are usually rusty as hell under the rubber boots and headlight ears. A vendor on eBay is selling internal spring replacements for $73.59 (plus $19.99 shipping) that are a direct bolt-on replacement for the worn-out forks that are likely on the CT in your garage. The nice thing about them is you have the choice of running the boots (or not) since the external springs are eliminated.

They're sold by "ophir4u" and the item number is 190781758091.

A set of replacement chrome tubes from Forking by Frank cost $250 so you can see what a tremendous buy these are. I bought a set and I'm very happy with 'em.

Not really. They're pretty much just a replacement but at least they're oil tight unlike trying to rebuild a set of forks with rusty, pitted tubes. I think the biggest advantage is that the springs are internal rather than external as on the stockers. You can still use the stock boots and headlight ears and unless somebody pulled up the boots and looked no one would know they're not stock. Another vendor on eBay sells CT-90 fork rebuild kits with the boots and such. Buying a rebuild kit and the replacement forks is still way cheaper than rebuilding the stockers if your time is worth anything.

Improving their action would be a matter of heavier fork oil, welding up and redrilling the dampener holes and trying to find stiffer springs. We're definitely not talking cartridge forks here...

Something off of an 80 moto-bike would be cool but the problem is you'd end up with a chopper looking thing with the front suspension way out of balance from the rear. You could have someone make some spacers to install under the damper rods to shorten the forks which would require either finding some shorter springs or wacking them to size.

I initially set up my my CT-200 based bike with an XR-100 front end and a Passport swingarm w/13+" shocks to balance out the bike. It sits a little high for my munchkin legs, though so I bought a set of XR-80 forks (2" shorter) and will try it with those fork legs and either replace the 13" shocks with stock Passport units or install a CT-90 swingarm and use the shocks I have on it now which will basically give it a stock ride height.

With the XR-100 forks, Passport swingarm and 13" shocks it puts some daylight between the rear tire and fender which looks pretty cool. Angling the swingarm like that does funny things to chain adjustment just like what happened back when dirt bikes first started moving the shocks forward in the early '70's for more travel. I put an XR-100 chain slider on the swingarm to keep the chain from sawing a hole in the crossmember and with the limited travel of the shocks I'm hoping keeping the proper tension on the chain with that setup won't be a problem. We'll see.

Side note--to use XR-80/100 forks on the CT/Passport chassis you have to lengthen the steering stem. I sawed mine in two, turned a plug on the lathe to match the I. D. of the steering stem and had it heliarc'ed in place.

plans change so fast, my 15 yo daughter saw the bike and lit up like a christmas tree! so its hers. and will remain slow and stock pretty much. it will be cool to have her in the garage instead of doing hair and nails in her room all day. im pretty excited about it as she hasnt really shown any interest in riding for years. since her z50 many moons ago.
all is right with the world.
