Yesterday I took my bike out and it was lacking power bad. When I pulled in the clutch it died and would not restart. Until it cooled down then I had to jump it because I killed the battery trying to start it. Today it started fine and warmed up fine and power was good but when it reached about 170 degrees it started to run like shit and would die at idle unless I gave it the gas. As long as I have had it, it never liked starting when it was warmed up I would have to give it gas to get it to start. Dealer told me that could be because of a bad battery now they say it could be electrical. I have not had them look at the bike because I'm not rich lol. This sucks I have only put about 900 miles since i got it. I have only had it about 3 months. The last time I rode it I took it 160 miles and had no problems. Can someone give me advice please. (And no I did not mess with the exhaust)

I am slowly realizing most Suzuki dealers don't got a clue diagnoses wise and only a small handful k.ow what their doing. Just my 2 cents as to what your issue is.....I ain't got a clue good luck dude

Sounds like you need a compression test on each cylinder and a leak down test. A bike running like shit when it gets hot typically means loss of compression. You may want to shop around for another motor. Regardless, it's going to cost you for service to do the tests and find out the truth. Do some reading on what entails a compression test and leak down.

Anyone got the tools and know how to take a look without costing me a ton of money. I know I'm asking for a lot lol.

Also how do I find out what motor will fit in my bike? If I have to replace it I would like it to be with a fuel injected one maybe a 750.

Hot start issue - probably need a new stator and rectifier. Check this thread:

http://www.gixxer.com/forums/showthread.php?t=282130&highlight=hot+start


I own the same bike and out of experience, my next guess would be a nice carb clean. I highly doubt that you'll need a new engine. These old carb'd bikes can be pretty tempermental when the carbs aren't clean and set correctly (float height, air/fuel screw, jet size, carb sync

The hot start issue sounds exactly like it. Shit the dealer would have cost me hundreds I love this forum lol Now how do I go about finding this stator and replacing it? lol Sorry for my ignorance on the issue but I'm new to bikes and don't know anyone that rides or fixes bike other than those I met here.

The thing is with some research you'll find that the stator and regulator have no impact on running.
charge the battery really good and unplug the stator take the bike for a ride you'll see it's not ignition.

Without patting any one on the back the lack of clearance at the valves will cause a hard starting issue while hot because the bike is loosing compression.Love ya Nick.

Any sign of back firing or popping in the air box??Would confirm this idea.

a short in the electrics might cause some voltage power to the starter to falter but I'd bet resistance some where.

check compression while hot and cold just for shits and giggles.

the stator is on the left side of the bike toward the bottom and looks like an engine cover. You might need to drain the oil a little before taking it off. You'll need a new gasket along with the new stator.

It looks like these:

The rectifier is under the tail plastic so you'll have to take that off to find it. Do more research on the gixxer.com site, it's a very common problem.

It looks like these:

You're still going to have to spend a good amount of money just on parts. That's the problem with old bikes - they have old parts.

I read that post from the GSXR site and I wonder if it was a short from the heat in the windings that caused an ignition issue.
Try just running on the battery once its hot see if it straightens out??

Seems strange because I've run a dozen bikes with the stator unpluged for testing purposes.

To run just the battery do I just unplug the stator?

My 96 750 alway had a hot start difficulty. But then I put a K&N airfilter in and the thing would die all the time and almost never start hot. Check that there are no air leaks around the filter, or that the airbox hasn't come off the carbs. The center two boots sometimed dont get seated properly and will leak air. That will cause problems. To tighten the airbox boots to the carbs, use long phillips thru the holes in the frame.

NOTE!!! These checks will cost you a 4mm, 6mm allenwrenches and a long philips screwdriver. If by chance any of this works, you GF owes me a BJ.

Only way to learn is by doing. I have replaced intake manifolds, ball joints, starters, ac compressors, water pumps, breaks, calipers etc on cars. I know I can fix a bike I just need some direction and advice. I wish I could spend money to have it fixed but it isn't possible at the moment due to lack of work.

Thanks to everyone for your advice. Time to start messing with it and eliminating possibilities. Anyone want to buy a bike? lol

have you put a voltmeter on it yet? what 3 readings did you get for running voltage? resistance?
not yet.

I was hoping people on here could tell me how to test something then I would test it and know if that part is bad or not. I am doing what I can with what I got. As soon as I get it running half way decent I will sell it and get a newer one.
 
#23 ·
Don't get discouraged by the haters. You bought this bike cheap and intended to use it as a learning tool. It you've done mechanical work on a car and have the confidence to try it, jump in and try it. Theres plenty of routes to help you on internet forums if you get stuck. And these 600 gixxers are plenty fast for a newer to intermediate rider so enjoy it (when it runs right :lmao:)

Please look for the fuse panel and check all of those wires in and out.
 
#25 ·
Just to let you know, you have a full yosh system on that bike. re-jetting is pretty much mandatory. Maybe it was done and maybe it wasn't. Also pull you airfilter and if it has a red element, then you have a K&N. With that combo jetting has to be done.

Check you plug wires and make sure none of them are abraided. You have plug top coils, check them with a multi-meter. See what the sparkplugs look like, is there an oddball color on one?

Do, lots of reading before checking this next one, but I would also check the throttle position sensor on the right side of the carbs. I have seen a couple loose ones.

Before buying any parts, send me a PM. I have tons of srad stuff.

To test the stator you will need a volt meter. Switch it to AC, unplug the stator. Start the bike and test all three combos for about 50-70 volts AC while holding the RPMs at about 4 grand. If you have anything less on any of the 3 combos you have a bad stator.

Follow me?
 
#32 · (Edited)
What do you mean by test all three combos?

After I unplug the stator do I hook the voltmeter to the battery?

Do yourself a favor, and get a factory service manual. With some searching, you can download an electronic version, but it's too big of a file (~95MB) to e-mail or I'd send you one.

The manual has the procedures for testing the stator and the rectifier, and just about anything else you need to do.

I've got a '98 600, but I haven't had any hot start issues so far.

you can also test the stator for resistance , with the bike off, across the 3 leads like ghopper said,

everyone is giving you good advice here, but there is alot of unknown with your bike so we are just guessing, you need a voltmeter

first test would be the battery, test voltage with bike off, then start it and watch the voltage as you slowly rev it to 5-6 K, did the voltage go up? this is easy to do , check the leads to the battery, are they tight? you should do this before the stator

Thank you everyone! I am going to try everything you suggested starting with free and working my way through. I downloaded the manual that is going to be a lot of help. Sqrly if I need any parts I will come to you first.

Well I took the battery in and had it tested and it was fine. I also used the voltmeter and it came up 12.73 off, 14.something while running and 13.53 when I rev it to 5k.
