His comment did not indicate whether it it had anything to do with EBR, and could have just as easily been about Cleveland, which was to have a new distribution network up by now and nothing but crickets there too...

Does LAP own Cleveland?
Cause he posted that he was under NDA with LAP nd posted it when things first went down this time.

>Does LAP own Cleveland?

Nope.

I took his comment there as just generally cryptic and tried not to read anything much into after the previous fiasco. This was around the time that very few knew that he'd hooked up with Cleveland and I figured he could just as well been reveling in that. Also figured he had his hands full financially in that and would not be able to make a swing for EBR this time, but maybe he got it for a song and is sitting on it.

Might be a boon to EBR in that Cleveland already has experience in the dealer-less sales approach that some have pitched.

The general consensus of this thread appears to be that parts availability for both the 1125 and the 1190 are waning and soon will be either non-existent or very expensive if found. We can witness this by observing escalating prices on eBay as well as other auction sites. This leaves us, the preservers of the Buell legacy, with the responsibility to either design and manufacture replacements or modify existing parts from other brands. I think we will all have to do our part.

In that light, I would like to point out that piston availability for these motors is also in the same category. When Erik introduced the RS, he used the aftermarket for many of his components and he chose CP pistons in the 106mm size. There are several companies that could make spare pistons, but most require large volumes. CP, sme other American companies, are willing to make pistons in low volumes, but there are all made from solid billet. There are NO forgings available in the double bridge style available in the US. Billet pistons are inferior to correctly sized forgings because they have less strength at the same weight and they must also use more piston to wall clearance as their thermal coefficient of expansion (COE)is greater. Ideally, AL4032 is the preferred alloy for street pistons because this eutectic alloy has a lower COE and can be run tighter in the engine. However, when piston temperature approaches or exceeds 300 degrees C, the strength of 4032 starts to rapidly fall off. Well 4032 pistons for these engines are simply not available anywhere. For racing and heavy duty pistons, 2618 is the preferred alloy because of superior strength at temperature. This is the alloy CP uses, but they are billet. I have spent the money to have pistons designed to my specs by Pistal in Italy. Fortunately Pistal did have forging blanks in the correct double bridge style in the correct bore size to be compatible to the Buell 1125 and 1190 bore sizes. Because the design now exists, these excellent pistons and pins are now available from Pistal at reasonable costs and they will deliver them in oversize diameters to facilitate reboring. These pistons are significantly lighter than OEM and the crank should be rebalanced when using them. Marine Crankshaft in California will do this at reasonable cost and they are the ONLY company that I found that will. My specs included a more efficient deck design to enhance flame propagation, flared and radiused valve pockets, hard anodized ring lands to prevent micro welding, as well as friction coated skirts. This double bridge forging also offers less mass at the pin boss, they can be run tighter in the bore than most 2618 pistons. These run very happily at .08mm clearance.

Marine Crankshaft has sufficient experience with crankshaft modifications for these engines. Their work is OEM quality, you could say.

We have another problem in the crank area that I have been unable to resolve. That issue is that of replacement bearing shells. First neither HD nor EBR has ever offered oversize bearings to facilitate regrinding the crank journals undersize. Replacement shells are only offered in standard size. I have been in conversation with many bearing manufacturers and none offer bearings in the 1125/1190 sizes. I have been unable to determine the OEM bearing shell source. So, if anyone knows the answer, please post it here.
