Kansas City Hoon- new to green bikes

[Chainsmoker]

Hi all, I went and picked up a 93 in pieces yesterday for 500 bucks! I have been racing a cr500 for the better part of two years now and just finished up an afc build using an 08 crf250 frame and I love it. My love for big bore smokers is color blind and with no project going on I figured what do I have to lose and there is nothing better than massaging an abused old smoker into a thumper eater. Anyways I was going over the pictures the guy sent me when I inquired about the bike and "holy 2-piece clutch cover" what did I get my hands on here?

The bike is complete with a freshly painted frame and a new top end kit included. I think the cylinder is goning to need re-plated and the bottom end is getting new seals, bearings, and rod. Any advice on what brand to use for this stuff would be appriciated, for example, you couldn't pay me to use weisco or hotrods cranks in my cr, similar scenario for the KX im assuming, OEM is best  but wouldn't mind saving a buck.  Thanks in advance for all the knowledge I will be mooching.

A Clymer was included but im still going to find the original, anyone got a manual for a 93 in PDF they would be willing to email me? I looked over the top end rebuild procedure posted and cleaning up the transfers and bridges doesn't look to be to hard with a steady hand. I have never had a crank balanced before due to the steel liner on the cr's, won't going from A-B-C-D pistons mess up the balance? lastly the clutch cover isn't stock correct? any ideas what it is off of or where it is from?

you'd be sending the piston along with the crank to be balanced...
no the clutch cover didn't come stock that way....it's not unusual to come across one that someone did...here's a good thread on 2 piece covers...

I guess I need to do more research on the topic, I assumed if you balanced the crank with one piston and replaced it with another on the next top end it would out of balance again. I've got a lot to learn

I can tell, 20 min on the forum and im already smarter...ish

1st lesson...
just remember, that "Go Big", does not necessarily mean....

[Chainsmoker]

HAHAHA, Thanks for the clarification.

While you have it apart, be sure to replace all the snap rings on the trans shafts.
remember.... you'll be pushing a lot more hp then the Hun.
Hp is hard on those thin little rings.

Don't know how you got that 2 piece clutch cover but there are a few guys here that would gladly take it off your hands.... Including me 
Nice find... It will be interesting to see what work has been done to your cylinder...
Post lots of pics..

Good call on the trans snap rings. I was pretty pumped about the clutch cover, I was hoping it was on of the sr mag covers but probably a good thing it not because judging from a quick once over it would be worthless due to corosion, had a little look at it last night, cylinder actually looks bone stock, plating wore smooth through around intake and exhaust port, play in the main bearings and big end rod bearing, but the crank still turns smooth. Gonna be interesting to see what I find when I get into the bottom end, hopefully Its not full of carnage. If its to bad that cover may be for sale.
