    Watch for this, I own a '73 Buffalo, and the center points have a different setting than the out board cylinders. Just something to keep in mind...

Just to get it started?? i would set the points at half the plug gap, about 14 to 17 thou, intake valves at 14 and exhaust at 17, these are rough figures, once the engine is hot if the valves are noisy, wait for engine to cool and reduce gap 1 or 2 thou and try again, these are just numbers i would use when in need, good luck

Go to this site and you can download a free PDF service manual.
www.carlsalter.com/motorcycle-manuals.asp They have a single manual for a GS750. It is for a 1976. That is close enough to your '78 to still be very useable.


Can I get a “very helpful” rating on this answer?

How do you set the points on a 1978 gs 750 suzuki


Two types of points were used on that bike. The ND system (condensers one on top of another) and the KOKUSAN system ( condensers left and right side by side). When ordering parts it will be important to know which system you have. All but one model use the ND system so I will assume you have the ND system.
Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site.

I could describe how to set the points and timing but it would be better if you had a factory service manual with photos and diagrams. Go to this site and you can download a free PDF service manual.
http://www.carlsalter.com/motorcycle-manuals.asp
It is a 86meg file. It took me about 8 minutes to download. The manual is actually for a 1976 bike but the timing and 95% of all else is the same for the 1998 bike. You now have more information on your bike than you will likely ever need. I suggest you take the file to Kinkos or a similar store and get a two sided printout of the file, 186 pages, 93 sheets. Have them 3 hole drill the sheets and then you can put the sheets in a 3 ring binder for easy reference.

Please consider a top rating on this solution. Thanks

How do I set timing on 1976 suzuki gt 380


Send me your e mail address to jonathangreen123@btinternet.com I wrote an essay on how to solve your problem and ran into trouble getting this site to accept it. I'll tell you all you need to know. For goodness sake don't give the engine the slightest bit of throttle abuse until you have set the timing correctly. If you do, you run the risk of holing a piston.
