Any tips on splitting the case? The factory phillip head bolts that hold the cases together seem like they will strip out easy and the case itself is pretty darn snug.
You need a hand held impact that you hit with a hammer to get those phillips screws out.
If you round out the phillips,you use a chisel to make a regular slot and try the impact again.
If that doesn't work, you carefully drill the center of the phillips recess with a drill the same size as the bolt diameter until the head pops off.Start with a smaller diameter drill and work up in size.
Then use vise grips to unscrew the rest of the bolt after the cases are split.
Then a brass or plastic hammer to tap on the ends of the shafts to split the cases.

I was a paid mechanic back when those screws were popular.

That bike looks great!

So my BW´s looked when I bought them:















Does someone have some pictures of the inside of a Fatcat engine?

WooHoo made some progress today! Engine out of the bike and working through some of the stubborn bolts I have the cylinder head off. The cylinder wall looks pretty clean to me but the piston top is caked with some carbon. Any simple stuff I can spray on it and the valves to clean them up?

Next I need to get to splitting the case.




Can I reuse this head gasket, It doesn't look torn at all.



I'm thankfully a bachelor for another 4 months.. so no more of the following going on in my dining room I suppose:

thanks guys. this bike is all kinds of awesome!!! i want to take it out to the dry lake bed outside of town this month and see what kind of trouble she will cause. it gets no respect though, was telling one of our new bosses i picked up a dirt bike and he got all ants in the pants and gave me some big story about how he used to race them. he asked what kind it was and it looked like someone kicked him in the pants when i told him it was a big wheel. no love.

vroom_vroom,

Awesome find. Get used to being snubbed. Family members, friends, strangers, former Yamaha engineers...the list of snubbers is long and deep.

Röhrich:

These are the promised photos of the under seat area on the 350:







This is with a Shorai battery installed, the main fuse replaced with a blade-type fuse and a healthy patina of mud and dirt. I should have taken a picture of Cliff's pristine machines.

I'll throw one in of Crusty Cliff drinking some iced tea out by the glacier:



Regards,

Mr. BigWheel

Good news!!!!! The Economy has finally recovered!

A new, old stock rear fender has just sold on eBay for $362 usd.

http://www.ebay.com/itm/281074952699...84.m1423.l2649

We'd better start buying those $900 carbs while they are still available.

As a tool and die maker I say this is possible by removing the brake disc from the hub,machining an aluminum adapter to mount a disc and machining a caliper mount that would replace the current drum brake backing plate assembly,act as a wheel spacer and use the lug on the fork for anti rotation.
Yes,it could be done with some custom parts.

If there is an interest in this I could work it out.

Choosing a common disc and caliper would be the first step.
I am converting my BW to disc but I am using a CR/XR disc and caliper on TriZ forks.
