94-97 zx9r motor question
Im new to the site but not new to bikes. But heres a question, what is the deal with the 94-97 zx9r motors that make them so prone to having problems, like blowing up for instance. What was done in 98 to make the engines so much better? Ive just acquired a 92zx7 with a zx9r motor. I believe its a 94-97 model so now i dont even know if i wanna keep it. I kinda like the bike but if i did keep it id wait till the motor in it crapped out,whats the newest zx7r motor that i can put in it that would be a direct bolt in? Its fast as can be. I actually traded my 97 zx6r for it. Ive had it for a month and have put 20 miles on it. When i went to look at it, it was supposed to need a front tire and turn signals. It actually needed turn signals and 2 new tires, but i drove a long way so i traded anyway. But it was running alittle rough on the low end but progressively got worse through the whole range so i took it to my local shop to find out it needed new jets, a vacuum diaphram, new float gaskets. Basically the last person in the carbs had no business being in the carbs. Hopefully i get it back sat cause i wanna ride. Is there anything i can do to ensure some longivity from this zx9 motor? The stamp on the motor is a zx900be008869. I was originally told it had a 2000 motor. But after looking at it in the shop today, and doing some homework, i found out that the 96-01 zx7 motors are very similiar to the 94-97 motor. And after i just tried to squeeze a 02 motor into my buddys 97 zx9 with no luck whatsoever, im thinking my motor is a 94-97. Can anyone help me out here? Thanks for any help and any opinions would be appreciated.
