I am looking for some ideas on a 89 CR 500. I am going to completely go through the bike and redo everything. Maybe an aluminum frame? Or keep it all original. Give me some feed back. Pictures would be nice to. Thanks all

I'd try and make the bike like Eric Geboers 1989 RC500!

Keep the steel frame.
Try and get newer generation Showa forks off Ebay. (Or KYB CR forks)
The 89/90 CR forks were terrible!

Depends on what direction you want to go.
Are you wanting a modern age novelty bike or a restored classic?
I personally like em traditional.

Also depends on what kind of base you have to start with.
If its haggard its going to be much cheaper and way less hassle to freshen up the motor and thrown it in a new four stroke corpse.

Salvaging a 15-20 year old hilljack hand me down is a nightmare.
Trust me, I'm about 1.5 years and a small fortune into a 93 500.

You will like looking at the Service Honda website, lots of nice CR500s for sale and some used ones to.

I put a fatty on mine and carbon fiber reeds. Honda mellowed them out by putting eyebrow reliefs above the exhaust port (compression reliefs).
To make them hit harder, either fill in these reliefs or bore the cylinder out .080. (Make sure wiseco still has pistons available).

I bought mine back after it sat outside under a semi trailer a few years ago but have since sold it to huge kid. Thing still ran great after getting the mouse nest outa the pipe.

The forks were horrendous but, I just slapped some stiffer springs in them (rear also) and hung on for dear life.

Holeshots were not a the problem.

A friend of mine let me ride his CR 500 in the sand dunes. It's the funnest bike I've ever rode. Rocket ship fast.

I have the right to remain awesome.

I had one that looked exactly like this. Only difference was the number 9 and a red and white Renthal pad. Like everyone else said, convert the forks and have the shock setup for your weight. Send the cylinder to Eric Gorr and bore the carb if you really want it to be rocketship fast.

Just remember "buyer beware" If the owner won't let you loosen critical fasteners to insure that they are free take your money elsewhere. Best money spent was on a Rekluse. Here is my 94 after restomod.

Get a set of CRF450/CR250R 47mm Showa forks, have the shock revalved/sprung and ride it. Here is my '92 with '96-up KYB clamps and 47mm Showa forks. You have to shjm the lower clamp with a Coke/Monster can but other than that they slide right in.

Since this picture I have trimmed the can shim so you cant see it. The Showa forks made a HUGE difference.

I hope you rerouted the front brake line when you had the forks off to trim the shim.

Yes, this was just a test fit, the caliper bolts are finger tight. I replaced the line with a new one and routed it correctly once I got done.

If you're gonna keep it in the steel frame, and I would, I'd swap those God awful forks for a set of 43mm conventionals or do a twin chamber swap. Either way is a big improvement.

Yep, either the '95-up 43mm KYBs or the 47mm Showa's are a massive step up from the stock '89 forks. Even going back to the 43mm conventional cartridge fork from '85-'88 are an improvement.

Stuff that sucker's motor into a 450 frame. Give it a modern update and make it look badass with new plastics.

If you're not mixing gas, you're not haulin ass.

If you are going to do an aluminum frame conversion, the '02-'07 CR250R is way easier and the end result works better than a 4T conversion, IMO. If you do it right, the only modification you have to do to the CR250R frame is the front motor mount tabs need to be relocated and you have to bend the right side engine cradle to clear the 500 water pump housing. No chopping of the Y or cradle needed.

95' up were 46mm USD KYB and they sucked slightly less than the 43mm USD KYB which wasn't even close to the 43mm conventional cartridge fork. I currently own all 3 and would choose the conventional over the other 2.

Correct, I got the sizes wrong. If i had an '89, I would go conventional 43mm or 47mm Showa. Pretty much everything in between is a step down.

that one's gonna stay the way Honda intended in 1989, I have a couple of others that I will modernize a little but I will never remove the heart of a CR500 and put it in another frame. Now building one from NOS motor parts is an entirely different matter haha

You need a .010" thick shim to maintain fork alignment. The typical thickness of a beverage can is .005" so you may want to check that. I use two layers of DP can.

10/31/2012 6:33 PM

Correct, I had forgotten that I used two layers, thanks for reminding me. You cant see it in that picture because I realized I needed two layers and cut the second one to the size of the clamp, but its there.

I don't care what anyone says, I would not ride a bike that had shim stock in the triple clamps.

Bad juju all around.
