Gas in my oil, tap-tap-aroo

[nova]

Well, stored my 92 cb750 at my cousins place for almost a year while away at school with the stipulation that he could ride it as payment for storage. I guess to him that meant he didn't have to maintain it. About a month ago my car got totaled and i needed transpo quick fast and in a hurry so i convinced him to throw it in his truck and haul it up to me (bout a 5 hour drive). As soon as we got it unloaded i did a quick check over and started it up. Ran crappy, figured it was the carbs also, had what sounded like lifter tap, that's when he told me he didn't winterize per my instructions. No prob just pull of the carbs and clean em out, might as well put fresh oil in too since he happened to mention that it was the same oil it had when i left it there. Here's where i get pissed. when i pulled the drain plug a wave of gasoline vapor hit my nostrils with enough pungency to bring a horse to tears. s???. Oil was thinner than water and little pretty shiny flakes of metal, which look good in paint but not in oil, were  seen floating around. He put around 1400 miles on it but no telling how many  where with the gas-oil. Anyway i cleaned the carbs, changed the oil and crossed my fingers. No luck, its got a low end knock at about 3grand that doesn't go away when the clutch is pulled, and a lifter tick.

Looks like I'm pullling an engine, Here are my questions-

1. what else should i be looking at closely besides the bearings and cylinder walls, this is my first bike engine teardown. I have found some used ones on ebay but there is nothing like the satisfaction of doing it yourself(and it will be cheaper if its just bearings).

2.  are there any special tools-besides a torque wrench- i would need

3. who makes the best manual for these guys, i have the Honda common manual but would like one specific to this model

4. whats the best way to take it out on my cousin (he has no money)

Thanks for any advice or encouragement

Wow, thats awful -- car totaled and bike is not there when you need it.

1. what else should i be looking at closely besides the bearings and cylinder walls, this is my first bike engine teardown. I have found some used ones on ebay but there is nothing like the satisfaction of doing it yourself(and it will be cheaper if its just bearings).

In addition, probably some new rings. Gasoline in your oil suggests that it blew past the rings due to excessive clearance. Also try to see where the metal particles came from.

2.  are there any special tools-besides a torque wrench- i would need

You'll need two ring compressors. I use Lisle 19000 ring compressors. Some people use zip ties instead. A micrometer would be nice to have also.

3. who makes the best manual for these guys, i have the Honda common manual but would like one specific to this model

Honda makes a manual specific to your bike. Its available through Amazon http://www.amazon.com/Honda-Factory-Service-1991-93-Nighthawk/dp/B002DKVDKG

4. whats the best way to take it out on my cousin (he has no money)

Have him do all the work while you supervise!

Thanks for the tech tips, im gonna pull that puppy out in two weeks when i have enough time off. I bought a dodge pickup with the slant six, its an 84 and runs like a ethiopian at lunch time, so for the time being i have some trasnpo. As far as my cousin goes, i trust him to turn a wrench like i trust
Burger King to cook a steak.

Forgot to answer that: I use cheapcycleparts.com . I'm sure others here know of some good suppliers too.

A truck, well that's perfect for carrying something I'd recommend most: A low mileage CB750 engine from a salvage yard or wherever you can find one. It might actually be cheaper than buying individual engine parts, and could save you a lot of time and effort.

I recently put together an engine for my '84 CB700SC using parts from an '86 junkyard engine, the original engine, and a cylinder head and block off of eBay. That junkyard engine more than paid for itself, and I can more than recover the $100 cost by selling unneeded engine parts on eBay.
