First off let me give an introduction...
As the title says, im new both to the bike and the forum.
I have an 05 Suzuki C50 boulevard cruiser that is my primary scoot. I wanted to get another bike as a project bike, one that i could use to hone my mechanical skills. I wound up coming across a 98 R6 on the cheap. According to the previous owner it needs to have the carbs rebuilt and new tires. But other than that its in good shape. (although he admits its been sitting for about 2 years)


Other than the obvious stuff, oil change, tune up, chain maint... etc, what should i look out for on a bike that's been sitting this long? Does the 98 have have any quirks or issues that should be noted, etc. are there any good reference sites for tear down and rebuild of this bike? any other useful info?. (ive seen a few good walkthroughs on projects that people have done on this site, so Kudos to them for that)

And lastly i will say that i have some mental issues with getting this bike up and running. This new bike, blows my c50 away in all respects. Lighter, more hp, faster. 47hp VS 108. top speed 90mph vs 164mph, etc. Im hard on the throttle on my cruiser, and im afraid, that will get me into trouble on this bike.

Anyway that's my intro,
Hello to all, and thanks for any information you can provide.

Well you can't argue the sportbike compared to your cruiser. However, since you are not a noob when it comes to bikes I don't believe the difference will get you into trouble. Though the horsepower is a lot higher, it takes a lot more revs to get there. It's not instantaneous.

Oh, and welcome!

you sure it's an R6 and not a ZX6R? just checking...this is a zx forum.
You are correct Kahearn. It is indeed a zx6r. Sorry, Ill try not to let that happen again. :) I don't have the bike yet, it should be delivered next weekend. I'll take pics as soon as i have it in my garage. But for now, ill post a link to a pic that is closest to what i can recall.

I guess the one thing that stood out was the single headlight and the dual ram air under it. And if i read the model overview correctly that would make it fall in the first revision or two of the ninja's.

And thanks all for the warm welcome. Much appreciated.

Ok gents (and ladies)
I picked up my 98 on thursday and have been slowly ripping it down over the last few days.
(ill get pics up if you want them)

Anyway, im finally at the carbs which is where the previous owner says there are problems. (but as im ripping it down, there are MANY MANY other issues. Destroyed wiring harnesses, brakes, chain, air filter, and now rotting carb sleeves)
One of the things i want to do is rebuild them or at the very least give them a good cleaning. Here's where the catch 22 comes in. Ive never rebuilt a carb before.
I have an ultrasonic cleaner, but its only big enough for one carb at a time.
It appears there are 3 long bolts holding the 4 carbs together plus misc interjoined tubes.
The item that worries me the most are the spring loaded throttle assemblies on each carb. Im afraid that if i separate the carbs, ill never get them back together.
(btw, kawa service manual on the way, but not sure thats gonna help with tearing down the carbs)

You guys have any advice?

I was going to edit the previous post and add pics, while moving the carb questions to another topic. So dis-regard the question above. :)

So here are some pics of my $100.00 basket case.
Ive already started stripping it down. I suppose i should have taken a couple of pics with it semi-assembled. But alot of stuff was already off of it. The PO had alot of stuff in a box. (hence basket case)

tank and carbs off.

and lastly the left side.


I think i have my work cut out for me on this one. I was told that it only needed carb work and 2 new tires, doesnt seem to be the case though.
Oh well its all good. It was meant to be a project bike anyway.

Welcome out - you are going to love the bike when you get it back together!


... However, since you are not a noob when it comes to bikes I don't believe the difference will get you into trouble. Though the horsepower is a lot higher, it takes a lot more revs to get there. It's not instantaneous...
Drunkula is right - I ride to work every day - my 00 is happy to stomp around in the 60-70km/h streets - occasionally get a inch or two air under the front wheel at the lights, but it does not happen by accident. But if you take her up over the 8k rpm, you had better have some clear road ahead.

And the hits just keep coming....
While cleaning/rebuilding the carbs, i found that carb 3 (going from left to right) had alot of grit in it. The vacuum slide would move, but wasnt smooth. As im taking it apart, I find that the tiny o-ring that is under the black plastic cover is missing. Im thinking this may be the cause of the grit, but im not sure. So i could use your opinions on it.

Anyway, i got it cleaned out (love my ultrasonic cleaner) and then it occured to me that if its making its way into the carb, more than likely, its making its way into the intake / valves/ upper cylinder. So i take a peeky see inside the intake. Sure enough there is about 1/8 - 1/4" of crud on the top of the left valve only. The right valve looks dried out and has nothing on it. no crud, no fluid, nothing. But it looks baked. (maybe its not seating completely and the combustion is heading up the intake????) I take a screw driver and grab a sample from the left side. The best way i can describe it would be flakes and beads about twice the size of a normal grain of sand sand.

at this point, i know i have to do something. Either a rebuild of the cylinders, maybe pistons, and possibly valves/seats or buy another engine.
The only issue i have with buying another engine is the fact that i cant come up with a large sum of cash so easily. the ones ive seen on ebay are anywhere from 500-800 + 200+ shipping.

Thoughts?

Do a compression test and a leak down test on all four cylinders and compare the results between them and see if #3 really is worse then the others.

What do the other lnlet ports look like? Got a pic of the crud?

It'll be a while before i can do a compression test. Some of the wiring harnesses have been chewed through. Im afraid to hook up a battery until i get them replaced.
The other ports seem ok to my UNTRAINED eye. what appears to be some carbon build up, along with fluid.

As far as the pics, Ill try and get some snapped up tomorrow night.

Ohh and what's a leak down test? (nvm, looked it up. One more specialized tool i dont have :) )
