Should I have an engine sprocket guard?

In my on going rebuild I'm replacing my clutch cable and much to my dismay I find I'm missing this sprocket guard. At least my clymer manual says I should have one. There are unused holes to bolt it on, but guard per se. I dug around on Kawi's website but can't locate it to get a part number.

This guard is a flat metal plate that covers the front engine sprocket and is nestled under the front sprocket cover.

Any ideas?

IMHO, it don't weigh much, don't usually get in the way of anything (unless you need the room for an oversized sprocket) and it may help limit the damage if you break a chain, so why not put one on.
If you list the year/model in question, maybe someone has an extra they would be willing to get rid of.

Sorry, I should have listed the model. I think I've updated my sig file to include it.

Anyway, it for a '78 KZ1000A2. I'm all for having one, its just I don't know where to find one, and I can't seem to locate it on Kawi's website to find a part number for it.

thanks for your help...Sam

Good question !
Im wondering if anyone knows if them chain guards are all exactly the same, or is some are different. My 750 - 4 has a 13 tooth front sprocket, and if I get a 14 tooth for the front, it would be extremely close to the front chain guard. I see the specs of some different models of KZ's that use a 15 or even 16 tooth front sproket on the same 750 engine. Is there a different front chain guard that allows the extra room ?

It's not just you Samwell...I just checked the fiche on www.partsfish.com and sure enough I cannot locate that cover you are talking about. Maybe they did not use it on your year bike even though the bolt holes are still there?

I don't think you absolutely have to have it anyhow. It might sling a little more grunge around in there and if the chain did break that would suck. I wouldn't worry about it.

i dont remember ever seeing a sprocket gaurd,the on thing i can think of is the perforated piece that mounts inside the cover,is this what youre talking about?

Is part # 21 not a sprocket cover? The discription is not but it sure looks like one: Part # 21 14025-1106 COVER,TRANSMISSION

13-14 are the pieces i was thinking about,is it one of these?

13 and 14 are covers, 21 is the trans cover while 22 is the gasket. The chain/sprocket guard bolts to #21 and is a flat piece of metal perpendicular to it. It forms a curve in front of the chain to prevent the chain from eating the crankcase when it breaks.

I am pretty sure if you were missing #21 you would aslo be missing lots of oil. It has a shaft seal that slides over the sprocket shaft. Without this seal lots of oil would be pouring out.

Yea, #21 mounts to the engine to seal the trans and is INSIDE the sprocket. The only "cover" I have seen is #13 and #14 which is insulation to deaden sound and maybe add a little strength. Generally the entire large cover is considered the sprocket cover. You have to have some kind of sprocker cover to mount the clutch cable to the clutch actuator/pushrod. Another cool option is this cover: www.pmfronline.com/clutch_release_kits.htm

I just realized that you are using a Clymer...they are for many different models/years. The early 900's had a cover like you are talking about. This diagram is from a '73 Z1. See part number 15. I don't think the later years had them.
