The best advice i can give you is "start buying cheep beer".

You will need the extra money.

Buy a clymer or haynes repair manual.

Get a Dennis Kirk catalog. WWW.denniskirk.com

Go out and buy a good Impact driver and a rubber coated dead blow hammer. 1 or 2 pounder

When you take out the phillips head bolts replace them with allen head bolts. The phillips head bolts strip out real easy, hence the impact driver.

Take good pictures of your bike before you take it apart. So you can have some type of idea how to reassemble it.

When you take the case covers off make a template of the case cover pattern in card board and poke holes where the bolts go. then one at a time take the bolts out and stick them in the proper hole in the cardboard. This is a good tip!!!

when you srtip screws or round bolts off  go to sears they sell good easy outs and bolt removers.

When evr you take out bolts (especially case cover bolts) put some anti-sieze on the threads.

Listen to the wise words of Charles Emerson Winchester III :

  " Do one thing at a time, do it very well and move on."

should i rip out the engine and do a full rebuild ?

If the engine turns over, I think I'd clean up the carbs., etc. and try to start it.  Who knows?  It might run fine.  If not, you haven't lost anything.


P.S.  Be sure to replace ATF first.      ;-)
