  • Returning Visitors

    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.

    Low Compression in 3 Cylinders 100 Miles After Rebuild

    Ditto on re-using the rings after a hone. The run-in is about the rings cutting off the peaks left on the liners left by the hone and the peaks cutting the rings to seal against any microscopic ovality, etc. The initial seating is quite aggressive and then it settles into a lapping process. The...

    81 GS1100 with 29 smoothbores.

    Pod filters and open bell mouths are notorious for this. I remember tuning my 83 GSX750E (16" front wheel) back in the day after fitting a nice set of chrome cap oval K&Ns and an air jet correction kit, and being amazed that I could effect the mixture at cruise by changing the position of my...

    1983 GS750e carb main jet and O-rings

    Hi there, can you give a little more detail on what throttle position/operation (constant, snapped open and held WFO, rolled-on?), the rev range and and under what load the bike was misbehaving? Different fuel circuits take charge at different loads and rpm and with the CV carbs fitted to an 83'...

    Did you replace the nitrile rubber plugs that sit over the pilot jets?

    GS850G Won't Start, Electrical Issue, No Spark

    Yes, the timing marks from the factory are good to go. Checking TDC by the screwdriver method or otherwise is only really something to look at if you've replaced or repaired something under the cover, or are unsure what a PO has done. Fix what's broken, not what's working.

    Yep, definitely works as a sanity check

    GS850G Won't Start, Electrical Issue, No Spark

    Hey Chuck, the problem with using a screw driver is that as the crank rotation passes over the TDC 'hump', piston travel per degree of rotation is exponentially smaller increments to the point the piston stops and reverses travel. And finding the point of travel reversal with any accuracy only...

    Add New Zealand to list. Here you can filter stationary or slow moving traffic. Slow moving can be a judgement call, your judgement against that of the police officer.

    GS850G Won't Start, Electrical Issue, No Spark

    There was a lot of parts sharing between models. The CMSNL website is great as it shows all the models that exact part was used on. Some parts do get superseded and are issued a new number. But they always follow the same part code format: With the ATU units, as far as I know, externally...

    GS850G Won't Start, Electrical Issue, No Spark

    The stock GS Suzuki electronic ignition is pretty basic. Its a pair of pick up coils that pass an alternating signal spike to the 'black box' Ignitor. Even the 'black box' isn't that complicated being really a pair of solid state relays alternately switched off in response to the polarity...

    1981 GS550 - Bogging at WOT and I'm stumped.

    Yeah, the mechanical advance and full advance timing was a light bulb moment for me. Bike was underwhelming when ignition was set to be 'correct' at idle. It is probably not the issue in this case, but you'd be surprised how much of difference it can make. A few degrees out is a lot when it...

    Yup, that the space where the plug goes.

    1981 GS550 - Bogging at WOT and I'm stumped.

    The rubber plugs over the pilot jets in the Mikuni BS are important. With the plugs in place the pilot draws fuel though the main jet (i.e all fuel entering the engine -apart from the choke circuit- passes through the main jet first). With out the plugs when the throttle is opened up fuel to the...

    GS850G won't go into gear from idle

    Gidday, it sounds like clutch drag. Which might be plates sticking due either oil sticking them together, or a physical impediment to operation (incorrect clutch pack assembly or damage/wear) or actuation problems (binding cable, incorrect positioning of release arm on the clutch cover). It may...
