Overhauling '84 CR500 engine...

[mightyhammer]

Okay, who can tell me what I need to do for my crank? I got tons of up and down and side play, basically rod bearing is shot... Now for the issue of finding a rebuild kit for the crank/rod. I think '85 and '86 are same as '84, but where can I get the parts for the rebuild, or a new/good replacment crank/rod? Please help!!!

If you have to pay someone to press the rod on it is not that much more to purchase a complete crank ass. from hot rod. I figured it saved me about $50 buying the complete package.

OEM rod parts only

[mightyhammer]

Hey roostie, glad you chimed in. What are your thoughts? Does Hot Rods make kits for the '84s? Or is that what you meant by OEM, I need to try to find an original?

[jr475]

Sorry about the HOT Rod suggestion I checked their page and they do not sell it for the 84, only 87 and up is offered.

[mightyhammer]

Thats okay, I don't think I will be able to find a new one or kit. Just have to find a good used one from what I'm seein'

[mightyhammer]

I see now grasshopper..... OEM whod'a thunk!

Get a (brand new) longer rod, and the deck spacer.

[mightyhammer]

Geeze Leweeze Bob, Stroke it huh? I have a hard nuff time keepin my fat ass on the damn thing stock! NO MO POWER!

[mightyhammer]

Believe this or not, you can actually get a rod kit from Honda...... I never would have believed it, still not sure. I placed my order and they said A-OK! $125 shipped!

[AlisoBob]

Geeze Leweeze Bob, Stroke it huh? I have a hard nuff time keepin my fat ass on the damn thing stock! NO MO POWER!

No, your changing the rod length, not the crank throw.

[AlisoBob]

...they said A-OK! $125 shipped!

I would buy every single one they had.... EVERY ONE.

[Roostius_Maximus]

big end pin and washers come seperate, dont miss those!

[mightyhammer]

You are right Bob, not adding to crank throw.
I am a little strapped for cash at the moment, got 5 bills goin out for a couple of parts bikes I found over in Oregon.
Trust me, when I catch back up I will surely be orderin' several mo'!

[mightyhammer]

Yessiree... got the little washers as well.

[mightyhammer]

Gotta love craigslist! Found a bike over in Oregon with a bad piston complete, another full bike minus seat and plastic with a yamaha 300 engine, a husky front rim with caliper and forks, a brand spankin new paddle tire all for 300 bux, well that plus the two bills for fuel and about a buk fitty for jerky pop tarts and energy drinks for the twelve hour roundy. Not a bad haul overall.....

I was trying to do a little research on these rods and found a few part numbers but what rods /years are actually the "short" rod engines?

With the info I found it would seem the 82-83 CR480's and the 84-86 CR500's have a different rod because they show a different part number. Now I'm wondering just how many length rods there actually were.

If the CR480 has a short rod and the 84-86 also has a short rod but different part number is the 82 - 83 CR480 shorter yet than the 84-86 CR500's?

The 1987 - 2001 CR500's would then be the long rod engines.
