Degreeing Camshafts -- Information Required

[Suzuki_Don]

The starter jet is the choke plunger. The Japanese call the choke circuit the starter circuit.

So are these numbered and are they different sizes. I would have thought that the BS32SS carbs would have all had the same size choke plunger on all versions of that size (32mm) carb.

For instance the 650E has a #47.5 starter jet and the 650G has a #45 starter jet going by the specs. With the same size carb, although I think the carb throttle plate has a different number on it, as does the carb body number stamped on it. Maybe it's a drilling within the carb and cannot be changed.

Don,
This doesnt have much to do with your BS32SS carbs but it does shows how much variation there can be in a single carb setup as it is adapted to different bikes. The carbs in the link are BST36SS which have been adapted to various GS1000/1100's and came stock on GSXR 750/1100's. You will notice changes in even the starter jet.

hmmm did this get sidetracked? Here's a picture of a great tool of mine that get's a lot of use just need a little plate bolted on somewhere for it to latch onto I've never cut camshafts to do this....

Yes, ROAD RACER, it did get a bit side tracked, but I started the thread and it's all to do with the my project (although I guess part of it should have been in the CARB section) so I guess that makes it OK.

That is a very interesting tool, would be interested to see it in action. The problem with degreeing the 8V camshafts is that the buckets/shims are completely obscurred by the camshat lobes. You can get a probe in there when the lobe is pointing up, but as it progesses around it moves the probe and upsets any readings. I found to remove the end of the camshaft as suggested was the best option for me.

The only drawback as I see it is you cannot use the Suzuki tool to do future shim adjustments. You must use the Zip Tie method, which is just as effective. That's only on #1 though. The tool can be used on the other cyls.

I'm going to be degreeing my cams as soon as I get the valves fixed. I can't do the cutoff method b/c my cam support is at the end, unlike the 8 valve GS. We've done a trial fit (bwringer and I) and we think the Summit tool I purchased may do the trick. I'll post some pics after all is said and done. I may start another thread, since this has evolved from a degreeing the camshaft thread into a general project build thread.

Kid here's the picture of that tool yes it's tight to get in there and I had an attachment for this indicator but couldn't find it. The snake is very useful for many things.More pictures in my albums..
