What do you think about my homemade push-rod protection mod?

I made it from rubber cylinder. Measured the distance from slave cylinder outer wall to rod seal and gave 5mm extra length so that it will be squeezed abit to seal both cylinder and push rod seal from dust and dirt.
Thanks for any good/bad comment. I haven't gone any test ride yet.
By the way ,i inspired from Clutch pushrod oil seal & breaking open the engine | All Motor, thanks @Berlin Germany.

hi turk-man :D

looks - hmmm - not nice ´n pretty but definitely useful :thumbsup:

if you now give the measurement results, you took/got, here to public it would be very helpful to imitators to build a copy of your´s. ;)

i guess the 5 mm more in length will be not helpfull to mount the sprocket cover again.
i personallly would shorten it to a plus length of around 1-1.5 mm at max - that would be i guess completely sufficiant for keeping the push rod and all stuff around clean.

I guess it's a damn fiddly job to determine the measurements, which is why I've never measured anything there.
so try and give us your results. :thumbsup:

How about an aluminum pushrod to go with that? Seems as though that would be as easy as buying an aluminum rod of he exact diameter as the OEM rod. It would take about 4.5 oz off the bike and cost very little. Would aluminum last or would it get soft from the heat and bend?
 
The Gen2 sprocket cover has a thin steel plate over the slave bore. The pushrod passes through a hole at the center of the plate. Yes, the plate is covered with grease and dirt but I don't think any got past the plate. If you use longer clutch slave screws, you could put such a plate over your slave bore and fasten it with nuts on the ends of the slave bolts. You would have to remove the sprocket cover if you ever wanted to take the slave off. What you have should work as long as it doesn't touch the chain or get stuck in the bore.

The thing about this mod I would question is:
It's rare,but Busa chains do break. Thankfully more often than not,the broken chain just falls to the ground. I wonder if having a big piece of material inside the sprocket cover would help or hurt in the event of a chain break.

Does it tangle up? Or fall to the ground easier

Meh...

Well i think stainless steel has much more tensile strength than most of aluminum alloys. Pure aluminum or plain aluminum would already bend at first press, would not stand that force.
Steel alloys are more strong than aluminum alloys generally. So i don't think whether it dares or not.
Also as i know , stainless steel is more chemical resistant than Aluminum alloys, correct me if i am wrong please.

I think if sprocket cover was stronger or if there was not enough space, the broken chain would stuck inside , squish and force sprocket and would crack motor block. So there are advantages and also disadvantages about it.

Hi. My clutch push rod is made of Titanium Robinsons transmission made it. I also have there out put shaft support kit with custom made light weight nuts and there billet transmission
 
I see titanium rod for about $20-30 for 36 inches. If the exact diameter could be found, it might be completely suitable if cut to the exact length and the ends were beveled down a bit with some sandpaper. I haven't removed my busa's pushrod yet but that's all the ZX-14's pushrod is plus it has a little detent at the center of each end. I think that was just to hold it in a lathe.
