I understand not having the extra money for this stuff, but not having the money to buy a leak tester or a good gasket set is a lot more desirable than not having the money to do a rebuild because you didn't take heed with this stuff.
I've been in a financial nightmare for the past several weeks. It started the day after I bought a set of shocks from a guy on here. After some very hard riding, I noticed that I'd broken my lower spring on the triples. I didn't notice it while riding because of the nature of the break, which meant that I could have continued to ride, but I chose not to so that I could avoid further damage. I'd rather stay off of it until I have the $450 to have the shocks redone than I had ride it once more and risk having to spend $900 on a set of new shocks.
You're in a similar situation, and I know first-hand that it sucks.
