It all started around last fall, as though this was the start of some kind of crazy Stephen King novel, last fall. I had been looking all over craigslist and eBay for a project vehicle. After looking through countless older Z's, MrkIII Supras, S13s, Z32s, and bikes of all brands and years, I finally narrow my search down to a 1993 GSX-R750 that I've come across multiple times and have noticed has been dropping in price :grin2: So I go out and have a look at the bike and realize that of course its not in as good of shape as the pictures made it out to be...turns out the bike is at the guy's brother-in-law's house and the wife wants the bike gone...imagine that right?? After having another look over the bike (mind you I've worked on automobiles for about 8 years now but I've never worked on a motorcycle so the extent of this is really more like yeah...all of the major components seem to be on the bike) and having the guy get the bike to turn over for me, I offer him $650. Long and short of it, I end up buying the bike and after a long process which included buying a bitchin' set of carbs from BadT on this forum(thanks again man, I can't wait to see them in action) and having to track down a previous owner of the bike in order to get it in my name I then found out that it was known the whole time that cylinder #3 wasn't making compression :shifty
Moral of the story is that craigslist is usually a cesspool ohttp://www.gixxer.com/forums/attachment.php?attachmentid=440809f people who are just trying to get rid of shit that no one wants to deal with and if you are looking for your next big purchase on there you should really be leery of what you are doing...
That being said I was looking for a "project" in the first place which means that I just ended up with a LOT more than I bargained for :twitch
So I decided to do the JE piston big bore upgrade since I was already looking at replacing the piston rings and placed the order.
After of disassembling, I am now just waiting on the pistons to arrive so that I can have everything machined and put it all back together :cheers

Damn...now I want a Corona! Gotta have a moto mechanic with you for those Craigslist bikes. You won't do that again. Good luck getting the bike back together. There are plenty of guys here to help you out if you run into additional trouble, which with any rebuild you likely will. Again good luck...we all would love to see the end result.

Off topic my inner voice tells me that you need to drink two more beers or I will start burning things. Also good luck on that bike :punk

Damn, I wish I knew a thing about bike engines. I'd love to work on something like this. Unfortunately, no room, and more importantly, no money to do it.

Thanks for all of the positive support guys! Also, in response to ruenin I have never worked on a bike engine before, but it seems pretty much just like a small in-line four on a car. The Clymer manual that came with the bike has been a tremendous help and gives you just enough info to figure it out. That being said this bike is being built on a VERY tight budget and I'm building it under a house in an area about the size of your average bathroom haha! Anything is possible, you just have to be willing and able I suppose...

Also, Clymer doesn't seem to really have a listing for the '93 that shows how to take out the valves, is this what my head is supposed to look like?

So it's been a while. I've since gotten everything machined and put back on the bike all the way up to the cylinder head (check the pictures below if you're into that sort of thing). Since I'm now running 907cc of of volumetric goodness, I decided that it would probably be a little thirstier than the stock set up so I bought the Factory Pro Stage 3 needle jets (P/N: CRB-S57-3.0). It says on the package to use with the K&N pod filters (which they have in stock and I plan on buying) and an aftermarket exhaust system. I've been looking everywhere I can think of and the only one I've been able to find is this one on eBay that is some Kerker brand that I've never heard of and they want like $700:gaah! Anyone know were to find a decent aftermarket exhaust for one of these?? I would prefer Yoshimura but I don't even see a part number listed on their website.

Kerker has been around since the early 70's,their 4-1 pipes make power,and at one point Kawasaki was installing them on their Eddie Lawson Factory Replica sold on the dealer floors.

Thanks for the insight oldgixxer, I am still new to the motorcycle scene so I have not yet familiarized myself with all of the various aftermarket manufacturers. Are there any other options out there?

Very slim pickin's the last several years. It's come down to finding a used pipe in condition and pay top dollar for it(i've seen them come up every now&then in our Classified forum,but they don't last long at all,or luck out after much searching and find a new,unused pipe someone hoarded. But be prepared to pay a rdiculous price.

From what I recall,with some tweaking of the spigot centerlines,an oil-cooled 1100 pipe will fit with a bit of effort;but it's be over 20yrs since I was messing with oil cooled and WC 1100's so I could have easily forgotten.

You could ask in the oil-cooled forum,they won't bite your head off,too much :lol

I see stuff in the WC classified. Yes, I have stuff there, but there are some older threads where guys are getting out of these bikes and still haven't sold all there parts. eg Yosh pipes, Hindle, rear sets, the ultimate rare front fairing, etc.
Get your Red R and you can visit!

Thanks oldgixxer, I'll have to check into that. Also, TJS, what the hell is a "red R" (I'm guessing you're not referring to the one painted on my fairing haha)?

Red R under your Signature signifies a paid membership and access to the Classified sections. Watercooled Classified isn't even view able until the Red R is purchased. Old Gixxer or Anthony D should be able to help you more.

I may have to track down the previous owner on mine, The title was sold almost 10 years ago .. yay
Damn! That's a long time! Do you have the title?? If you don't you might just want to see what you can do about filing for a lost/stolen title depending on the bike, state, ect.



Also UPDATE! I finally got the bike back together and filled with fluids! Went to start it and it sounded like it wanted to start for a second and then just endlessly turned over :banghead

Soo, my first question is which spark plug wire on the rear coil goes to which spark plug? Currently I have the top wire going to cylinder #1 and the bottom one going to cylinder #4 simply because that is the only configuration that the wire lengths will allow for. If anyone could give me some guidance it would be much appreciated!
