If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

    Won’t rev past 7000 rpm

    KiwiAlfa156 Yeah it’s called GS400 in canada but it’s the same as GSX400 in the usa. I also just tested the spark plug caps detached from the coil wire and was getting 8.8k on the left cap and 9k on the right cap

    Won’t rev past 7000 rpm

    KiwiAlfa156 I can get it to 8500 Rpm in neutral on the centre stand but as soon as i’m in any gear it maxes at 7000 with WOT. The exhaust also sometimes Pops when giving throttle. Not quite a backfire. No leaks in exhaust and the pilot screws run best at 2.5-3 turns out

    Won’t rev past 7000 rpm

    KiwiAlfa156 The right lines up good with Fire and the left lines up too but will shake back and forth before the F and after the F. I have the points set at 0.014. Both have good static timing

    Won’t rev past 7000 rpm

    Hey everyone, After months of working on my 1980 Suzuki GSX400E, I finally got it running and idling steady, and it rides great. But there’s one issue I can’t figure out—it won’t rev past 7,000 RPM, whether it’s under load or just revving in neutral. Here’s what I’ve done: • Set the ignition...

    Clutch Engagement Point

    I’ve adjusted the clutch push rod screw, the bottom cable adjuster and the lever adjuster to 4mm like the manual says. The engagement point is still happening with the lever fully out. I’ve messed with different settings for the adjusters and it never changes the engagement point. Any ideas? Are...

    Loose Shift Lever

    1980 Suzuki GSX400E. Somethings up with the shift lever. If the bolt is fully tightened down the lever doesn’t move at all. If the bolt is just a little loose it’ll move but no matter if it’s a little loose or a lot loose it stills moves around like crazy. I’ve taken it off and compared what i...

    1980 Suzuki GSX400 Choke issues

    I’ve disassembled and cleaned the carb on my 1980 Suzuki GSX400 four times now. The bike runs and rides well, but I’m having some trouble with starting. If I have the choke even slightly on (1/4 on), it struggles to start and will stall unless I give it constant throttle. I can usually get it...

    1980 GSX400E Starting issues

    Yes, I cleaned the pilot jets and main jets and blew air through everything. I could see light through both. Put the carb back on. Still didn’t run good. Took the carb off and cleaned them again 2 more times. Same issue

    1980 GSX400E Starting issues

    Last year, my 1980 Suzuki GSX400E ran perfectly after being fixed up by my buddy. I started it once over winter and then it sat for six months over the winter, and of course now it will barely run. I've cleaned the carbs thoroughly multiple times and the diaphrams and everything are all good...
