I've always run regular in mine. Manual states 91 ROZ which I believe translates to 87 ROM. Cannot get real gas easily around here but have not had any problems with the corny stuff.

Thanks Chaos. I pumped 2 gal of 87 in just to get me by til cold weather hits. Simply doing shorter test rides for now. But I will run 90 pure gas after that. As I always keep a small/fresh supply on hand for the other bikes.

I see your in SW Ohio. I got a buddy/acquaintance from Cinci. He own Piston Society motorcycle rental. http://pistonsociety.com Keeps a couple BMWs for rental. He a BIG fan of BMWs old and new.

Every spring we meet up w a group in Kentucky for a long weekend of riding. This spring, on our way home. I am planning to stop in and see his new store along w a Zero bike hes going to have.

Digging all the sand and crap out packed around water pump has been a chore.

On a lighter note...

Got the "new/old" solo seat installed and adjusted. I dont think the dude on ebay was lying. He said it came on his 88 when he bought it new. Replaced it w a 2 up seat after only having it 3 days and its been packed and stored ever since.

Nice profile/shop shot there. The 87s do have a certain raw quality to them, the solo seat looks good!
I have the "rumbleseat" Corbin on mine but I haven't flipped to the rear position except for once or twice with the wife.

What's the build date on your bike? I'll check mine...

Fingers crossed this leak is simply the engine cover gasket and not the mating surface twixed the cases.

Most likely it is the cover gasket, bud. Re-torque the screws or replace the gasket and screw bushings. One of the causes of a leak from the crankcase cover can be the bike's falling over onto it.

thanks, I will give it a try. And yes, it has fallen over at some point.
I went forward and ordered the gasket along w enough bushings to do both covers. They are all showing age cracks.
and I already have the two valve cover gasket's that came in the tune up kit.

trek97 · « **Reply #85 on:** October 22, 2016, 02:40:47 PM »

Snugged it up maybe just 2 lbs. Its looking like the leak has moved. I also checked the valve cover bolts...one bolt was finger tight. Ha.
I also just ordered a new 1/4" drive inch/lb torque wrench. Ive always gotten by w my cheapy 3/8"...but shits gettin serious now.

trek97 · « **Reply #86 on:** October 23, 2016, 06:24:40 PM »

While looking at installing the tragkorb brackets. Discovered my right peg plate is bent pretty badly. About an inch.
Also discovered Right plates are non-exsistant on ebay. Hooray. They got like 10 left plates. Found the ONLY available, mis-match Right k100 plate I believe will work w a bit of hole drilling. So I will have a spare of sorts until I can find the correct part.

The tragkorb bracket should be mounted behind the plate. Ugh.

One option...With a bit of grinding on the tragkorb bracket I could make it work bolting it to the front side of the plate. However I would have to completely delete the rear foot peg. AND I do have the solo seat on it.

Moving forward w option 2... I bolted a make-shift pry bar to the rear foot peg hole. And began gently pulling it.

I think we all know where this is headed.

Yep, cracked it. But now its straight and as luck has it. I am buddies w the worlds greatest aluminum welder, just down the hallway at work.

So, It fits really nice now. Will drop it off w Gary tomorrow.

Also found what was making that occasional pesky little squeak in the rear end. The spring was just kissing the rim.
So got that taken care of.

Over all a pretty productive weekend.

Wait until next week, or did all of the Ks crash and fall over to the right?
Unistrut jigging is a good thing. Bike is looking oh so clean!

It is becoming even clearer that we crash on the right side maybe even 10/ 11
Would not want to crunch the cam sprockets on the left.

The Mighty Gryphon · « **Reply #90 on:** October 23, 2016, 10:03:29 PM »

Yes, these bikes have a strong tendency to fall to the right, probably because the sidestand is on the left. It is not just footpeg plates. Just search eBay for mirrors, fairing lower panels, and side cases. Left side components outnumber right by at least 5 to 1.

Martin · « **Reply #91 on:** October 23, 2016, 10:05:51 PM »

It doesn't seem to matter whether you drive on the left or the right, they always see to go down on the right hand side. I've had 4 drops in 19 years all on the right hand side, mates had 2 drops in 4 years both right hand. Every time the side stand did not enter in to it :dunno I would love to know why, I have pondered on it and I still can't come up with a logical reason.

He just wants to be different, he won't conform to set Brick standards for falling off.

Unless your looking for right peg plates, then its 10 to none.

trek97 · « **Reply #97 on:** October 24, 2016, 06:44:51 AM »

This machine in particular has been down on both sides. :musicboohoo:

trek97 · « **Reply #98 on:** October 27, 2016, 06:34:35 PM »

Got the plate welded up. And I may have to fix a water pump leak.
So far I have 2 drops hit the floor since I pressure washed the front and oil pan last Saturday.
I suppose it could be left over engine degreaser and muck, that didnt get fully rinsed out.
It has no oil or antifreeze odor at all. Time will tell.

trek97 · « **Reply #99 on:** October 29, 2016, 08:25:17 AM »

Replaced the leaky crank cover gasket and bolt grommets.

Found the issue. The cover has been tweaked when PO dropped it. If this dont seal I will have to work to straighten or re-face it.

I now see, there is plenty of room (engineered into design) for over torquing the bolts to warp a damaged cover. So, that is a possibly plan A.

BMW MUST have seen this coming to allow concession for that. I am surprised they didnt, also, employ a finer thread bolt for this.
