xb9Rr Flywheel compatible w/ xb9sx?

A piston broke in my 2007 xb9sx and one of the connecting rods is bent. I need to replace my flywheel and am wondering if I can use a 2003-2007 xb9r flywheel to replace the original.

This the flywheel I'm looking at purchasing:https://www.ebay.com/itm/Buell-XB9R-...608?nav=SEARCH

I'm also going to get the nrhs 1050 big bore kit to replace the cylinders as one of the cylinders was damaged. Is there anything else that I should replace so I can have piece of mind once it's all out back together. Sidenote: a shop is doing these repairs.

Thanks.

Ouch! What the hell happened? Well, it seems like you are working with the right person (Dan @ NRHS). Have you discussed this with him? He has been doing this a long time and will give great advice while not trying to sell you what you don't need. I will buy my next engine kit from him, no questions asked.

YES. but before you buy i'd suggest confirming with seller that in fact it is a 03-07 XB crank. have him measure the crank pin. should be 1.25 inches OD. an 08-10 crank will fit BUT the caveat is that you must swap to the later style complete alternator assembly and a few tidbits of hardware to make it work.

I'm in Mexico City right now, but I rode down from Seattle. My xb9 started to make a light rattle right around the same time that I painted the exhaust and put it back on the bike. I kind of thought it might have been the torca clamp on the exhaust because I reused it instead of replacing it. Then, 1000 miles later, the rattling suddenly got louder and the bike lost engine power on the highway.

I'm not exactly sure what caused the piston failure, but it seems like the 07s might be susceptible to crank/piston failure. http://www.badweatherbikers.com/buel...tml?1378945265
The piston was broken and the connecting rod was bent.

Thanks for recommending that I speak with Dan about the issue. I messaged him and he gave me some good feedback.

Hello Lunaticfringe. Long time listener, first time caller. :)

Thanks for the detailed info on the part. I really want to swap over to an 08-10 crank, because I've read that it's way better than the 03-07 crank, but I want to keep the work I'm having done in Mexico to the minimum. I asked the seller to confirm the details of the part and got no reply, so I went with an 03 crank that seemed like it was in good condition.

How far south are you heading? Are you from Europe?

You might be better off to sticking to stock. The last thing you probably wanted was to get into the middle of a Buell engine mod project at a shop instead of riding.

There is a fun video series on YouTube about some people who drive a VW Bus from tip to tip of America (Chile to Alaska). They roached a few engines along the way and some of the conditions makes Cooters infamous roadside repair look like a factory job. Good watch if you have time, and it may help morale watching what these guys did.

Seattle to Mexico city on an XB9? You Sir, get a tip of my cap:angel:

This is that video.

But just the tip....😁

I'm from the states. I was going to go to Guatamala at the very least, but they closed their border due to Coronavirus. It's been a great trip so far and I'd definitely recommend Mexico and\or Baja to anyone who's considering it.

Thanks for the link.

Well, pics or it didn’t happen! :)

Just some random pics of the trip so far. A lot of these pictures are from baja. https://www.buellxb.com/forum/album.php?albumid=258

It was the best of times, it was the worst of times.

How was it with all the cargo over the tank?

Cool, story bro..... and not in a sarcastic way... but I want to be your jimmy the cricket. Don’t fix the bike on the road.. boarders are closed right know, find a shipping company and ship your bike back to the states or sell it down there and buy another bike and continue you road quest.

I did look at your pictures and that rod rattled all around so more then likely your case is toast too. So not only do you need pistons/cylinder, crank, head you will need some case work... and unless your running the Baja and just want to slap it together and limp it it’s to much work to have done unless your in Mexico City then just find a replacement motor for real cheap.

A couple of years ago I was in a similar situation but was only about 1,700 miles from my house and still in the states.. I was going to just do a complete motor swap but the dealer was still 3weeks out and I was not going to stay in a hotel for three weeks with my thumb up my ass so I bought another bike finished out my ride then threw them both in a uhaul and drove back. But that added another $2700 plus the cost of another bike to my trip...

Squid has a good point. Finding a complete motor may be the easiest/cheapest route, but you do you man. Great pics:eagerness:

Awesome trip! Any ideas why the motor let go? Did the fan quit, or 1,000 miles of low octane detonation?

I’m kinda curious... what does the rear head look like?

The tank bag was fine, it only has clothing in it so not much weight at all. I had tools and rarely used items in the tailbag and important items and electronics in a small backpack. The backpack could rest on the tailbag most of the time, so it didn't really cause much fatigue. I packed as light as possible for this trip.

Damn, it really sucks to hear that there is probably more damage than just the flywheel, pistons, and cylinders. I might just have to sell it down here then, because it might not be worth the risk of ruining the new parts or having another mechanical failure. Foreigners can't legally buy or register vehicles in Mexico, so buying another bike here is out of the question. I guess if I want to continue on, I'd have to go back to the states, buy another (non-buell) motorcycle, and ride it back into Mexico. There's honestly no other bike that I'd rather be riding than a Buell, but any problem that requires a mechanic or parts down here means SIGNIFICANT down time.

I honestly didn't pay much attention to it. I was pretty focused on the shattered piston and cylinder when I was there.

Yeah, there's only one xb9 engine that I can find for sale in Mexio. It cost $1350 and is in questionable condition. I might have to take the L on this one.....

Jeez, I REALLY wish that I knew. The fan is working fine, but I did have to fill up with 87 a couple of times because it was all they had. I did ride with the rattle for over 1,000 miles though. :(
