crashed my bike - pretty bad

The forks are pointing straight forward...

Hmmm...



Golly!



Let's see, those are cylinder studs, right?

Uuups, that must have been some fall. Glad that you came throught relatively unharmed and are getting better. Hope you will get on that bike again and soon.

greetings from a wet, windy and dark north. No weather out for man nor bike to paraphrase W.C. Fields

Ouchie Rob !!

I think that you did fare better than the bike - hopefully those cylinder studs didn't pull through the case when they were folded over.
I think that you can count on new jugs and heads - hopefully just on that left side though if the engine ran for a while in that state
there could be more problems with the parts of the engine that don't look so "dramatic".

When you had mentioned that your left cylinder broke the other guys final drive open I figured that it must have been a pretty forceful impact.  Yowzers !   Even though the newer oilheads I don't think are made as tough as our airheads are, that was a pretty rough collision and you do have to count your lucky stars that you're not so bad off.

How is the other rider doing ?   Has he replaced the final drive on his bike yet ?    It looks like the leg shield on that left side took a good hit too - probably saved you even more damage to your leg in the process.

It's gonna be interesting removing that head.

I sure hope that Rich's Ebay find will help a lot if that is the way Rob wants to go. What a great gesture to find all that stuff and alert Rob! What is left over may be of interest to any one of us too! Good on ya Rich!!

I am so pleased that you have your bike under your care again, Rob. I know what it feels like as I went and trailered LRB home from the mechanics last Thursday. Even though it was a 3.5 hour drive one way, it is so worth it to know LRB now has a new rear main seal and oil pump O-ring, new neutral switch, spline lube on both ends!, new gas line, a snappy throttle movement, sync'ed carbs, new floats in the carbs, new timing chain, new input shaft seal ? no idea what this is, new crankcase vent hose, new transmission boot and throwout bearing service. Now I have him all winterized but the best part is being able to go out to the Brrrm Closet and see him there and maybe shine him up a bit.! Very settling to know the bike is safe and close by.

Keep up the exercises Rob. It will pay off. That sure was a thwack!! Well, Rob, at least when we do something we do it up well...right!!!?

   Yee Ouch!!

Thanks for the links, Rich!

The head is useless, as it has larger valves than the right-side that is on the bike.

The engine, OTOH...

[MrRiden]

Sorry I didn't know 'bout the differing valve sizes. Just thinkin' that engine might  partially pay for itself by the time you built one and pieced out what was left.

I bought the engine.

I had the money to cover it, but I don't get paid again until the 20th...


The seller must have a dark side -

the engine was $500 BIN, and the shipping was $166.23....

for a total of $666.23

Thank God for pennies.

Last night I went out and examined the frame gussets at the steering head.  There were no visual stress marks.

Umm, not meaning to rain on your parade, Rob, but isn't your bike a 79 ?  You probably  know better than I about this, but I'm not sure  if just changing over the clutch carrier assembly/flywheel from your 79 will enable you to bolt on your 79's transmission to that 1982 era engine ?  Do the flywheel bolt patterns match/line up, or is some extra machining/part swapping required ?  

For the price, it seems like the engine purchase it was a pretty good deal, and  less costly than replacing all the individual pieces, if you can make the transmission/clutch graft work - I've just never personally tried to put a post 81 light flywheel power plant on a pre-81 heavy flywheel transmission before.   I am sure that if it can be done, you're the guy to do it, and the BMW is the bike to do it with !   Be sure to photograph things so  the rest of us can learn !

Yeah, I know about the difference, but I am pretty sure the conversion has been done before.  Unclear on the details at this point, though.

The Nikasil and big valves will more than make up for it, not to mention going backward over 50,000 miles!

Hi Rob

If you need a beancan, voltage regulator, ignition coil, ignition module and/or a rectifier for your new engine, feel free to ask. Apart from the beancan, you can have the items for the transportation costs.

[Rob Valdez 79 R65]

Thanks, trolle, but I think I am set for electrics.  

This is the 2nd transplant for this frame, and the 2nd engine came with all electrics!  So I have had spares for a while, as well as there was probably no damage to those components.  Even though this is a '82 engine, I will probably run points on it.  Especially if they stripped the ignition from it.

But I will keep your generous offer in mind if it turns out I need/want to go electronic!  Thank you!

Rob,

Options:

1.  You will have to change the input shaft on your present gearbox to use the post 81 lighter clutch assembly - if it comes with the engine.

2.  However, you should be able to use your existing clutch assembly and forget about the lighter one as your old flywheel will bolt up to the crank - which I believe it should - as I do know that fitting a lighter flywheel to an old heavy flywheel motor is possible.  You could even get someone to shave a few pounds off your existing flywheel if you wanted.

3.  Flog your current gearbox on ebay as a serviceable spare and buy a post 81 gearbox - without losing money if possible - to acquire the input shaft.

At least you will have acquired an extra 5 horses and a lighter motor........nikasil bores, lighter starter motor (i.e. not the Bosch?) etc.

And you could flog the good side (head, barrel, piston and any other ancilleries that you will not need) of your motor to recoup some cash, as they will not be interchangeable with your current motor.

There is always a silver lining to every cloud..
