Kickstart for the Hima

Looks like it is Meant to be there, well actually I would prefer Black with a slight bend to fit with the aesthetics of the frame.
That's definately on the to-do listLooks like it is Meant to be there, well actually I would prefer Black with a slight bend to fit with the aesthetics of the frame.
Mine is a 2019 BS4 and this is how it looks at that area. The hole is missing that sleeve.

Yes, this is an unmachined hole. I found the youtube video of Sam's 500 conversion of his BS3 and that one is machined like mine. Best guess right now is that only BS3 has machined holes. Could be running into issues when kickstarting a fuel injeced himalayan, maybe thats why RE skipped this.
It's already there..
Good news and bad news... I managed to put it all together and fi the kickstarter kit onto my bike. First let the bike run on electric start to see if my engine didnt explode.. It didn't and ran without additional noise! Finally tried kicking it and managed to start it at least once!
The biggest issue right now is the force required to move the pedal. I destroyed already one of these high quality chinese pedals... The 500cc with increased compression and the HT-B cam without decompressor makes it a b.tch to start. Which is quite logical actually, since most modern single cylinder engines above lets say 250-350cc run decompressors.
Now planning to switch back to original cam with decompressor to see how that goes.

Changed the cam to OEM but didn't seem to make much of a difference. Was quite bummed for a while, because that meant back to the drawing board or maybe ending op as a decoration piece only. Went searching through some parts and found the kickstarters Sam send to me. There was one that was even longer (and much sturdier/heavier). Gave it a shot and welded the arm to the lower part from the chinese kickstarter that was already gone. Definately improved the experience! It still separates the boys from the men but it's doable. So without further ado, here is a clip of the first kickstarted Himalayan!
This is so awesome @barima, it needed more leverage, good call. Great job!
Thanks guys! This project pushed me to the limit of homemade engineering. Only have to work out a decent kickstarter and then it's good to go i guess. I forgot to weigh the parts when i put them in my bike, but i would say around 2-3 kilos depending on the weight of the kickstarter. If we switch to titanium for all parts then it will be much less
Production expectations... Well this is a homemade prototype and even if i would replicate a kit , i wouldn't consider it "sellable" . It has still many design flaws. Also, essentially all parts of the kit are modified in one way or another. That's why it took so long.... ahum ;-) So for production all parts (around 10) need to be refabricated. This would require some serious (financial and engineering) investment.

Can you guess the amount needed for a say 100 pieces production run? Also: there are changes to be made to the side panel, how difficult are those to make with "garage tools"?
Thats a tough one. Since i already spent 100 Euro on chinese parts where quality is (too) low, i certainly think that it cant be produced cheaper.
So thats already 10k and no engineering done. Ideally you want the shaft to be chrome plated to reduce friction but it will all add to the cost. And thats only one of many considerations.
Modifying the clutch cover with garage tools is hardly an option. I can think of a scenarion where a mould is needed and a special tool but this has all to be developed. Better to supply the kit with a machined cover or leave it to the DYI guys (who probably have access to a machinist as well). You dont want a leaking cover because the customer overestimated his garage tool skills.
As this is not an option for one of us to stem individually (I guess - or do we have any hidden millionaires here?) it seems the only way to go is a go-fund-me campaign which might generate enough interest and cash. But to start such a thing there needs to be a comprehensive list of the items needed.
After an afternoon of fabricating i came up to this frankenstein result (i btutchered two chinese kickstarters together) which should come close to what RE had intended. It has about the same length as the Bullet kickstarter in the video. It clears the footpeg when foldeed up.
Its quite long but doesnt hinder my leg when sitting in riding position. The quality is questionable but i hope it will last for some time so i can test it out. I have already ridden a few 100 kms and the gears inside didnt expolde yet so thats a good thing....
