Yes, my first ride on the XR will happen today, since I purchased it back in late March. I have a Dyno scheduled to repace the old FuelPak and tune it for "rideability" with the new Power Vision. RC Cycles in Hayward is the place.
Home RC Cycles Hayward, CA (510) 471-9755
Engine-related additions, are a drop-in K&N, new SE Plugs and Wires, and Bassani Roadrage 2-1 Exhaust. Everything else is stock. I'll report back with the print-out, and after ride report, once I stop smiling!!!

So, why have I waited so long to ride? Back when I saw my first pictures and racing of the AMA XR Series, I wanted one. I initially wanted a Buell XB12, but due to the parts issues, I swayed to the XR. Had been looking for an XR for a long time, and just missed out on buying a street-converted ex-race bike. Found another low-mileage 09 Vivid Black, and it already had a few mods on it. It was well within my price range, and talked to my wife about it. I have had an old truck that I've been talking about selling for years. I threw in the following, "If I buy this XR, I will not ride it till I sell the truck." This was my words, not hers telling me to sell the truck. I like my marriage, and want to keep it that way, so we agreed. So many calls, very few lookers.

But wait? You are thinking I sold the truck, and now I can ride the XR? Nope! I have a "Hall Pass" for this week to ride it before going to the Bagger Races at Sonoma Raceway (Sears Point) with @amarzano and @ranbush this coming Sunday, and I'm getting use to it before the 160 mile round trip. I have never ridden this until today. Not even sneeking a ride down the street. Started it many times, letting it warm up, made vroom-vroom sounds, changed quite a few things, have a few more to change later on, but kept my promise, and have not ridden it, nor have let anyone else ride it.

Full report with pictures, later today, and yes, I'll be careful!

Well the sound is not good, in fact it is a deep knock, not something like a tapping sound that was explained to me. I should have been told that with a sound like that, you should tow it out, not ride it home, at least then I could have been prepared. I'll be picking it up next Monday with a truck. No external leaks. I havent paid for anything yet, and they could not get me any print-outs of the sheets I asked for, because the 5 recorded runs they made can only be printed our on the owner's computer, and he is off this week. The dyno guy wasn't there either, so no one else could get them. I did get to see them, but using a Factory Pro Dyno there, the readings are not anything like the Dynojet Dyno where I had it tuned before. Looks like they started with a downloaded "canned" Dynojet Tune, then went from there in the tuning due to the fuel line was overly rich low RPMs. I know I signed the paperwork, and in it stated if something happens to the engine on the dyno, it is all on me. Almost 15,000 miles on this bike, and now I wait a week to get it, and overthink what it could be, and what direction I am going. I am not selling it, nor am I getting another bike.

So, BRG Racing first impression: No matter what their reputation is like, no matter how many pictures on their walls of other racers are hanging there, cummunication gets a less than zero from me. Even the guy that paid before I was waiting to be assisted, asked "Where is my discount for paying cash?" They said that is what you owe, unless you pay with a credit card, and that adds 4% to your total for the credit card fees. I won't know what lies inside the engine till I have it checked out a week from Tuesday. No intentions of taking it back at this point..

You all can fire away with the questions, as I have completed my sob story.

Sorry to hear this Cory. Sounds like a compleate clusterf--k.
I hope it is nothing serious.
If it is, you can always go the Hammer 1275 route.

Well I won’t know what it is till I get it inspected.
@raven you are not the first to recommend this, but it is not in the cards at this time. The forks were next, so those will go on the back-burner.

Bummer. I know you'll get it sorted out. Working at a dealership you have access to the keenest ears available. Hopefully one of the techs has heard this noise before and nothing is busted.

Very disappointing update. Keeping fingers crossed till you get the bike back and apart.

Agreed. Before I jump to conclusions, which is about all the exercise I get, I'll await the inspection results next week.

That sucks, although it's impossible to blame them, it's got to make you wonder !

At least it's only knocking and hasn't thrown a rod or such like and caused real damage.

Hopefully it won't be nothing too serious and you get it fixed at a reasonable cost, just be glad you're not over here where HD parts seem to cost an arm & leg.

I'm very sorry to read this Corey. But you will be able to get her fixed and finish the build

Ok here’s an update. The Dyno shop called me and asked if they could remove the primary cover and inspect that area. I told the they could because they are already charging me to do so. I get a call stating the front pulley bolt has backed out, and it was hitting the side cover. I know it was a new bolt and washer, and I torqued it correctly(apparently I did not). He sent me a video of the pulley back on the crankshaft with excess play. I will pick it up with a truck on Monday, and have one of the Techs at my work check it out. I have shown them the video, and they will inspect it for damage on Tuesday.

Here is the video they sent me so all can see. If if that bolt backed out, it is all on me.

If the crank splines are badly worn, then it will be repaired, but sent out for all the work first. Welding, balancing, and lightening. 1275 kit will be done, because I will be in there. If I don’t, then I will regret it, as I don't want to do a stock rebuild.

More info next week.

Picked up the XR today from the Dyno, and we worked it all out. Thanks to my Boss, I used the work truck with the hydraulic bike platform to get it and bring it back. It will be checked out in the next few days and it will go back for the finishing touches on the Dyno. This, only after I get the approval of the Techs after they look at the crank splines. The Dyno shop reinstalled the stator pulley, torqued the bolt, added fluid, and no noise once started. If all checks out, they will schedule me when I can ride it there and wait for them to finish the tune.

Don't know how much the pulley could/did move off the shaft shaft, but it could've damaged the splines on the end of the shaft and the back of the pulley, which when re-assembled will appear ok for a while, but will wear loose quickly.

A hydraulic bike platform? How convenient. Still doing it the old way around my neck of the woods, a ramp and full physical involvement!

Did the dyno shop say it would be ok or is it a ticking time bomb? I suppose no one would want to give any guarantees but it would be tempting to leave it and keep fingers crossed. It was caught early minimising the risk of damage and I can't imagine a reputable and knowledgeable shop putting it back together and running it if there was no hope.

Good luck with it

5:00 am in CA, so coffee hasn't kicked in just yet. I do appreciate the comments and suggestions.

They left that decision up to me, and I will get a professional opinion from my Techs when the inspect it today. Hoping for the best, but I have options if needed.

Convenient for it purpose as a work truck, but a lowered truck has always been easy for me to use with a ramp and tie-downs. Have yet to load the much heavier XR in my truck yet, as the engine is in the finishing stages of a rebuild.

I was told is it is up to me. The Dyno Shop does repairs on bikes, but they are not H-D Proficient, so this is why I picked it up, and having the H-D Tech look it over and will follow their suggestions.

Thank you, I am hoping for the lesser of two evils, but am preparred for the worst if needed.

Report later when I get more information.

Because some of you would want to know...

The first sheet is how it came to them in red, and the current non-completed final in yellow is where it is now. Remember, Factory Pro readings are different that Dynojet readings.

ADDED
This might read confusing, but here goes.

Added a picture of the overlay tunes from RC Cycles. The initial(red) and final (blue) in Dynojet.

From BRG's Factory Pro Dyno information below, their initial tune (in red) is that same final tune (blue) from Dynojet, translated to Factory Pro Dyno. That was what was explained to me, as BRG tuned from what I had in there when I dropped it off.

I still await the diagnosis from the shop on the crank/pulley.

Here you all go. Fire away with the roll-eyes.

No paint markings on the clutch spring plate indicated the plate has been on replaced. I installed the SE Clutch and Spring Plate while in there

H-D Tech recommended replacing this bolt that threads into the crank. Also recommended to be replaced when doing the Scotty Mod, as I did. Sadly this bolt is obsolete. Had to call a bunch of H-D Dealers and found one in stock at one in my area.

Inside of the Primary Cover shows slight damage from the bolt hitting it, but the cover will be OK.

Now for the bad part. The crank splines are damaged. The splines on the pulley are stronger and have very little damage. Because I did not clean the inner threads of the crank before adding red thread lock, the bolt didn’t get torqued correctly. Note to everyone that this can happen if you don’t.

Crank will need to be replaced or sent to Dark Horse in WI for repair, welding, balancing and lightening will be on the list even if it is replaced. The shop doesn’t want to deal with all the aftermarket 1275 Kit stuff so at minimal, I will think about doing the ported bigger valve heads, and a stock rebuild. Will need to have it tuned again after all is complete. I have other options, and the shop is going to work with me on it too.

Not giving up on this bike. It is too much fun. More later…

Cory, Buells have the same crankshaft.
Don't know if that is of any help?
