Default Logged my first ride on the CR500 on Independence Day

     

Since I finally got my 98 500 into riding shape this week, I decided that the 4th of July would be the perfect day to take it out for it's inaugural run. I was really pleased with how the bike ran, other than not wanting to idle very bad and being a bear to start. Hopefully some jetting tweaks can resolve the starting issue and if not, I guess I'll throw my PWK on it. We rode a fairly easy 30 mile loop but did hit some technical and low speed stuff that gave me a chance to see how the bike handled being lugged. I was SUPER impressed with how much I could lug the engine and it just kept going. There were several spots where I know my old YZ450 would have flamed out but the big CR just kept plugging along.
My only complaint was the vibration, holy good lord. Those of you that say the 500's don't vibrate must just be used to it. It wasn't bad all the time but there was a definite spot on the RPM that made it shake like a mother, I mostly felt it at the pegs. I'll re-torque all the engine mounting bolts before the next ride to see if that helps any. All in all it was a great first ride, some minor suspension and jetting tweaks and she will be dialed in!

Glad you're on the big CR.
Btw-My '82 and '92 were smooth as silk, the '85 did vibrate.
I would say get your crank balanced, or you may be experiencing a crank going bad.

Regardless of crank condition and even balancing, when you get a single cylinder with a piston that big, it's gonna shake. Just the way it goes. The 4 stroke 450's are smoother because they run a counter balancer that reduces vibes. The 2 stroke bikes don't have them. Funny though because the 250R quad has one. Not sure if they were trying to save weight and space or reduce reciprocating mass by not installing them on the bikes.

Big bore 2 strokes rattle.Comes with the territory.If they are clapped out or hodge podged together its worse.Their is some remedy but its minimal.

CR 500 in its day was not known as a torquer.
20-30 years later prolly feels that way to the newer generation

Hey Cowboy... good to hear you got the ole 500 going. As for the vibration... like has been said the 500's will vibrate. I've ridden several different brands from different years and if you hop off anything but another 500 you're gonna notice vibration. When I did my 500 I had the crank balanced by Crankworks... it still vibrates although I don't think it's bad and probably the smoothest 500 I've ridden. It starts pretty decent usually 2 kicks... after three slow kicks with the choke on. I installed the PWK 39.5 and it works great. Good luck with it... long live the 500's!

I know these bikes can and will vibrate, no issues there. This old girl at the right RPM really shakes though, felt like a dang paint shaker between my feet!

For anyone interested, here are some videos of the old girl at work.

There's been a lot of talk about pistons on the banned site.
Discussions about weight and vibration etc...
You may have read them since you are a member too.
I don't know, I had a preconceived notion about vibration and clutch pull from an '85 back in '85.
However, my '92 was smooth and the clutch pull was like a 125.
Same thing on the '82.
The '85 did vibrate though, same as the one I had in '85.
Motor mounts tight? Frame cracked maybe?

One other thing.
None of my business I know but, please reconsider riding those type of places alone.
One wrong move and down the side of a steep mountain.
Think about your kids.
Sorry to butt in but I couldn't help it. Hope you understand.

I've read the discussions at banned for sure. I have not opened this motor up but I do know the PO rebuilt it and used a Hot Rods crank. My intention is to pull it all back down and put the OEM crank back in, when I get around to that I can also see what he used for a piston. I wanted to get at least one ride on it before I pulled the motor down.

The concerns are appreciated but not warranted; I had another guy with me I don't much care for riding alone if I can help it for the reasons you stated; the risk of something happening and nobody finding you for who knows how long isn't really worth it.

Wow those are some awesome trails! Riding that 500 through all that slow tight stuff looks exhausting! Lots of clutch work and that hit every time you start to roll it on. Can't beat the sound and smell though!

In all honesty the clutch work was minimal. Having never really ridden the 'ol half liter before I wasn't sure what to expect but I was pretty happy with how it did. Right now it's geared at 14/51 and it seemed to work very well with that setup. It's kind of hard to hear but in the short video clip there were a few spots where I had it lugging pretty hard hopping over the roots and rocks and it just kept on eating. I was impressed with how well the bike does when ridden a gear high and kept off the pipe. I'm used to riding 450's in this stuff so the 500 wasn't all that exhausting, even being out of shape and practice.

A Gnarley pipe and flywheel weight are great for the 500 if you ride in the woods.

Cool. Have fun with it! Get the 500 finished so you can start posting more stuff about that 95 CR250. That thing looks clean. In the market for one myself...

Not much planned for the 250 other than get the pipe and silencer straightened out to as new condition. It's so clean and original I don't really want to mess with it at all. I've toted my son around on it a little bit and that's it. He shared the first ride on the 95 with me on father's day:

Yeah, I saw that post before. So the plan is to keep it as a show piece?

You need to shrink wrap that 250 for your son.
That's the cleanest one I've seen in a long time.

Not necessarily a show piece but I want to keep it original. I do want to ride it on occasion but I want to preserve the condition as best I can. In all honesty some reproduction graphics and a little paint on the frame and it would be about 98% of showroom condition. I think it's pretty cool to have one of this vintage in this great of original condition so I don't really want to doll it up for the sake of dolling it up. It's a killer bike and looks amazing for its age!

Yeah, it looks awesome! Although they are hideous, there's something about those mid 90's CR's that I love.

Hideous? How dare you insult my girl like that... them are fightin' words!

The colors on the 95 are definitely loud and obnoxious. My wife says she can see it coming from a half mile away because it's so bright... it's definitely not subtle!
