Compensating for something
I just had to deal with a stuck bolt in the expanding end of the pin. Tap the pin out from the drive side gently, there's a good chance it will move with only light force. I had to clamp the pin in a vice and even with liberal application of kroil, loosening the seized bolt took some effort. There's zero chance I could have done that with the pin still in the frame.

Thanks [B]sundaydoug[/B]/Stihacka and everyone to confirming this, they really are amazing Westagil. I would think they would make it easier to do or have a fail save for it, if does get stuck or corroded with galvanized metals... like a wench point or something lol its totally covered in bushings, hahaha I cant get a grip unless I wanna destroy it...Ill probs get like a circle type of plier to add even pressure on one of the bushings to get out the lower bolt...ugh to much also seemed that the threw bolts for both wheels are stuck or striped...wooohoooo hahah

Cleaned it even more now looking awesome and more limber in tune/less mud dirt everywhere in the bearings and joints.I changed the bars to a way less wide boy and used my genius to duct taping the lose memory foam seat to look cleaner :P.
I might just ride this for now and hopefully not break it when i do do the wheels and suspension.... but Ill convert it to a Ebike on Friday but thanks for the info it really helped really is intimidating not knowing if you gonna break it :D

well thats just not a option for people that live in flat states or even have the time to travel to 8hour away trails....but you guys sure have a sour spot for ebikes not like im in a competition with one wth. You guys are like the gas car guys, get over it, electricity is fun.

I live in the second flattest country in Europe and still do not see the need to electrify a legendary DH bike. Buy something with less history or a new one.
I also think it is a shame that some owners think they need to convert their classic cars to EVs. These are pieces of history and should be preserved to showcase the engineering from that period. If you really want an EV looking like a classic car and have more money than sense, then have a replica build.

Lots of owners convert nice old cars to all sorts of crap. What passes today for a hot rod comes to mind... old 4x4s converted to inane brodozers... I saw a Shelby Cobra a couple of weeks ago that was so gussied up with badges, chrome accessories, and other crap that it looked like an older woman so covered an makeup, shitty clothing, and jewelry as to be unrecognizable as human.

I know, and it sucks!!! There should be a law protecting historic stuff, similar to what there is for buildings. At least for the not mass produced stuff.

Okay then have a good handful of the classics in a bike museum, I shouldn't have to pay like 3k to 7k for a full suspension ebike...with horrible range, when I can make it custom for 1-2k with goodish range and speed... like 20mph limited really...what is this a granny scooter show...

I get what you mean the Sundays were the pinnacle of DH bikes from 2006 but nowadays you gotta really look to find a good modern one, that doesnt take your bank account or even break in a couple years, as well. it doesn't cost that much to make they just over inflating them to make way more money then they should.....

This Sunday WC survived a beating since 2007 and now it looks kinda good now with tlc, they dont make it like that anymore. but idk if someone is willing to pay a good price for it, ill look elsewhere for a bike as this does speak to me to not be messed with. life is just to conflicting

I think it's a much better faith for a Sunday to be ridden as an e-monster than rotting in someone's shed - as long as it isn't abused as a singletrack intimidation machine.
Yeah this guy had it rotting in his garage for like 2 years with dirt and grime, even the previous owner didn't keep it in good condition, while not even cleaning it up...I think im the 4th owner, that even actually cared for it. really sucks how people don't tlc for there belongings. Just now I changed the shifter cable and tuning it up as we speak hahah.

We are adamant to much for keeping things stock but then you are stuck in the past, do your best to make the present better then the past. Ill keep the stock parts so when I want to get a new ebike, ill refresh it to new with paint and stickers.

but if any one knows where to buy a rebuild kit for the bearings and bolts that would be awesome.

Whoaaa!! I need moar details of this project, it sounds amazing!!!
Thanks boys,
Yeah like it is converted to 27.5 with a 460 CS, around 63 degree HA and 470 Reach. Wheelbase should be around 1300mm. Frame + shock + saddle is around 5.7kg.
The tubes i got are a bit different in size but i am happy to even get some made of the right alloy. I now need to wait some months because this needs to happen in order for the material to gain back its strength.
The design i am aiming for is Hills 2008 bike with a couple of my own touches.

7000 séries aluminum tubes? Did you build the frame? Tell me more please.

Exactly. Pretty difficult to get in Austria and right diameter. A friend of mine welded it (I can weld steel but aluminium is another story), I made the frame jig and organized everything from tubes to donor frame. Unfortunately I am not able (at least how it stands now) to CNC every part new, hence I needed a donor Sunday for Seattube, Gussets and other bits and pieces. From start to finish it took us around 3-4 weeks. Since the heat coming from welding was so much some parts warped a bit but nothing major. For example I had to ream the seat tube in order for the seat post to fit again, but those are just peanuts. The dude who welded it for me also makes honey and grows habanero haha.
We also made a special fork to accomodate for 29 inch wheel. I don't quite like the feel of the new Boxxer Debon Air and as we all know "air is for tires" I made it myself. Thats why I wanted an old Boxxer with Coil Spring setup. It is actually a Boxxer with the first Gen Charger and Coil Spring, lowered into Yari/Lyrik Lowers and homemade CNC machined Crowns. New crowns because the Stanchions of the Yari/Lyrik are a bit further appart than on the other forks. Resulting in 15mm thru axle, 180mm travel (Because the limitation of the travel is done by having the bottom out bumpers a couple of mm higher than the actual lower leg is deep) and around 48mm offset. It is similar to what SRAM athletes ran a couple of years ago when there was no Boxxer 29. Look for "Lyxxer" on various internet forums. Hence the "blackbox" sticker, also a little homage to Hills 2008 ironhorse.
I made a first prototype back in January, but there I only changed the front triangle to be a bit bigger. But as it was our first go at it the geometry was a bit messy. Therefor we redid everything again with the numbers I wanted.

What gen Boxxer stanchions are those? Are they the most recent version or previous? Would love to go coil on my Boxxer 29er. The Boxxer air spring just lacks stability
Its the boxxer stanchions from the first 35mm boxxer. I think its called Boxxer B1. You can run a coil setup in the new boxxer too but its messy and kinda sketchy. The old steel springs that came with boxxer team are too short to fit in there so you would need some kind of spacer to make up the extra space. The new boxxer has longer stanchions than the old one.
