    Just picked up a 1987 ninja zx600r

    Hey everyone, just picked up a very clean 1987 ninja zx600r today. 17k miles and very clean. Just needs some carb cleaning to smooth out rough ride under throttle. I wont be looking to go crazy with it, thinking maybe k&n drop in filter, remove baffles in stock mufflers or wait for a deal for a 4-1 system and stage 1 jet kit? Need an indertail kit of some sort and flush mount blinkers to clean up the body a bit. Want to keep it mostly oem due to its condition. Doing oil and filter change, new spark plugs and the carb work in the next few days.

    Any suggestions on parts to get or ways to make the bike better? Or things to look out for?

    Wow. That's a clean bike. Someone kept that is great condition. My first bike was a 92 600r, so your pics really take me back. Nice find!

    Thanks! I wasnt looking for one specifically but a deals a deal, scored it for $500. Already cleaned the carbs, it still ran poorly then all of a sudden cleared up and runs smooth now. Did spark plugs and oil/filter change. Need to order an air filter and some brake pads otherwise shouldnt need anything.

    Im a sucker for fast toys so naturally id like to make it quicker but dont want to sacrifice reliablility or condition as its so clean. May just leave it stock as it is and care for it until I get another faster bike. Cant eait to get it on the road this week.

    So I think I need a little help, bike was running well after I cleaned the carbs but now after riding for a very short time the will bog and stall out at a stop randomly after riding so well. Bike is fully stock so I assume jets are stock and looked very clean when i put it all back together. New plugs show what looks to be a lean condition as well. Any ideas why it would run well and then randomly die from fuel starvation?

    Im going to pull the carbs and clean them again and double check the air/fuel screw or idle mixture screws whichever its called lol. Any idea what the stock amount of turns out the screws are suppost to be set at? Cant seem to find exact info in the clymer manual I have. Will end up syncing them of it comes to it as well. Otherwise bike felt great while ot goes until it decides to not go anymore lol.

    Another update, pulled the carbs again and cleaned them as best I could. Bike now runs well, at least I think it does. I have no clue how they run when in perfect working order so i dont have anything to base it on. But it starts easy with choke and once warmed up has no issue idling and revving pretty freely. Bike seems to be lacking low end power although with a zx12 being my last bike it may be normal for the zx600 as it has quite a bit less power. Still need to sync the carbs but ive ridden it 50 miles so far and all is well.

    Definetly need to do something about the exhaust, its much too quiet. Wasnt able to hear my bike when riding next to my buddies 2003 honda vtx1300 with vance and hines pipes. May remove baffles in stock mufflers until i can find a decent priced 4-1 setup. Would i be able to get away without having to rejet if i just remove the baffles? Or maybe just turn out the mixture screw to richin it up a bit? Really dont want to pull the carbs a 3rd time lol.

    I would definitely sync the carbs. That may resolve any lingering issues you have. I can't speak for running on stock jets with a modified exhaust. On all of the carb bikes I have had, I always rejetted once the mufflers were modded.

    If it's still running rough on you after you sync the carbs, you may want to start looking at some of the old rubber throughout the intake. At that age, it is probably more hard than soft so I would suspect you could have a vacuum leak. Of course, if it's running well then enjoy it and ride it.

    Carb sync is on the to do list for today, I dont suspect it to be very far off if at all. I think its just the low power output ill have to get used too. 165-170ish hp in my zx12 compared to 70ish hp in the zx600 is a hell of a difference. But it rides well, decent power and smooth. Heavy old girl but not the worst. Few things id like to adjust like the clutch grab which is almost all the way off the bar, i prefer it around half way engagement point. Also has some rolling resistance in the front end, did the brake pads and bo change. Going to double check air in the tires. Maybe bearings are on the way out. Either way im very happy with the bike and couldnt ask for more considering its condition and for $500.

    That bike is too clean to gut the mufflers. Pull them, store them, and put something else on their if you need to sound like an angry mosquito.
    Skill is what keeps you on two wheels.

    Situational awareness combined with skill is what keeps you out of harm's way.

    ATGATT combined with Situational Awareness and Skill means you might live to ride another day when that deer runs into your bike or that drunk blows through that stop sign.

    It could be the bike needs a valve adjustment. Those bikes needed them adjusted about every 6-8000 miles. It can and will lose power if the valves are tight...plus it will break one if it gets tight enough!

    Thats probably what im going to do, cant bring myself to cut into the mufflers with them being in such good shape. Ill hold off until i find a 4-1 setup and get the jetkit and filter at the same time.

    I do plan on doing the valves soon as im not sure when the last time they were adjusted. You can hear the valves a bit but ive always been told its better to hear them than not hear them as that could be a sign they are too tight. In any case doesnt appear to be difficult so ill tackle the job soon. Want to ride a few more nice days before pulling all the bodywork off again lol

    Keep the stock pipes in reserve... you can find pipes for that bike pretty easy.

    That thing is super clean! You really scored a great bike for almost nothing.

    Yeah thats the plan, keep the stock pipes and hopefully find a decently priced 4-1 setup. Ive actually had a hard time tracking anything down for it. Ebay showed a few results for exhausts but Ive been striking out. Its much too quiet though so hope to get something soon.

    I gave it a light buff with a da polisher and it brought even more life to the bodywork, still cant believe the shape its in. Maybe someone on here could answer this for me, the emmissions related items that sit on the top of the motor, can they be deleted? I remember doing similar on my old zx12r with block off plates and some caps. Would be very simple but i cant find info to confirm if it is okay for the bike or not. Its running great otherwise, should be a fun summer.

    I did some poking around and could not find any headers... but there are slip ons out there.

    You might have to stick with the 4 into 2 configuration.

    I found a decent 4-1 muzzy setup on ebay for $200 free shipping which isnt bad. But I figure for a pipe, jetkit and filter it should run about $350-$375ish. Ill do them all at the same time so it can be tuned properly. And then I can store the stock pipes and not have to modify them at all.
