Title: Kick start rubber
Post by: a101960 on 31.07. 2017 15:45
Has anyone found a way of preventing kick start rubbers from working their way off the pedal after 2 or 3 kicks?

I have an almost unconscious habit of kicking the end of the rubber with the side of my boot after the engine starts.

I use the rubbers that are open both ends, they seem to stay on better ( a bit better antway)

 I had same problem and after a few 'new' replacements that split in a short time decided to make my own using oil hose with a SS inner sleeve, and custom washer to hold it on

Kickstarter rubber from a Yamaha DT400 works well.

currently ados f2 is holding. previously some construction adhesive worked for a while.
make a nail hole in the end of the rubber to relieve the pressure when sliding it on, and maybe a lose clamp overnight to hold in place.
but its an average solution, not great

Modern replacements are crap! Sorry, but most are.  I have had rubber bits go to cracked and junk while the bike is on the bench for a rebuild (Okay, admittedly I sometimes take a long time) but it is disheartening to have fork boots, kick rubbers, shifter rubbers and footpeg prophylactics crack and fall apart in short order.

Never use silicone based materials (its bad news and gets near your paint makes it hell for anyone to ever repaint again) But there ARE a few products that will keep your rubber bits pliable and near new.  (Stay away from Armour All as well,,it makes it nice for a short while but accelerates wear and decay).

Glue or adhesive is generally not great for  a kicker as with the motion of the kick, the rubber piece should not stay fixed or stationary... Rolls a bit under the boot.  But I have seen and done it myself a few times is take some stainless acft safety wire (0.032 thou") and do 2 turns smartly around the end furthest away from the bike. Many kickers have a blob or knob on the end anyway so adjacent to that.  Do the pigtail short and tuck it back in so not to protrude and stays on the underside out of site.

Use care when cinching up the stainless wire tight. You want it very secure but not so much as to slice THRU the rubber or distort it too bad.  You just want to cinch things up near the proud end so it doesnt slip off.  Remember about that rotate while kicking bit as well. (So, goldilocks tight, not TOO tight and not too loose)

many people secure grips this way too, and hoses instead of clamps.  Done right it looks good, done wrong,, it looks bad.  I am sure there is some dandy safety wire classes on youtube these days.

Also very handy tool to have to secure bits known to fall off. (its equally useful for airplanes and old Iron bikes)

(Dont poke your eye out!)

I drill & tap a thread in the end of the kick start lever find a s/s washer about 25 mm in diameter & a screw to suit thread you have tapped out I have done this to my A10, B31 & B33 with complete sucess

I make sure all mine start 1st kick so its not a problem  *smile*

No seriously, I have the inbuilt habit that muskrat and greybeard have, I kick it over and automatically boot the rubber whether its coming off or not

sluggo, i would be very careful wirelocking on a original bsa if i was you. an unauthorised repair and dubious standard modification in my book. wirelocking the sump bolts is a sure fire way of telling that bikes been raced in the past and past its best. wirelock only on the 2 primary drive inner cover bolts or if riding in quest for the maudes trophy.

Bugga. Ed just gave me up. I'll have to delete the "just used on Sundays to go to church by a grandmother" in my for sale add.

Ish. Maybe she just tapped it on with her boot afterwards?
