Hi Guys, I'm looking for some input, BUELL XB9s. Either the "Bolt on Kit" or the "Big Bore Kit" 1050 vs 1170. Both have advantages and varied co$t$. http://www.nrhsperformance.com/ekitbuellxb9r.shtml http://www.revperf.com/XB9-XB12/xbPerformKits.html QUESTION: NRHSperformance, say's that both don't need machine boring the casing, where on Revolution Perf. it say's the 1170 does need boring. Which is true ?? I live in australia, to get the kit here is about $1k, then approx up to $1.8k to do all the work with dyno tune etc. If I need to have the case boring, then the cost can be very expensive. So, what's everyones views on this? How many of you have added a big bore kit? Which kit set is the preferred. (not prepared to go cheap, want quality) Any input is greatly appreciated. Cheers. | ||

I would ask the guys at jt and s perfomance. I know they intall them there. You can find them on the sponsor page. | ||

Ya can't go 1170cc (3-13/16" bore) on an XB9 without boring the cases. I'd go with Revolution Performance, no question. I've known the manager there for years and he's top notch. Tell them that Blake/BadWeatherBikers.com sent you. These are the same folks who provided the cylinders for the Buell Racing XBRR machines. (Message edited by blake on February 08, 2011) | ||

Cheers Blake, Much appreciated. Will gladly mention your name when I contact them. | ||

On the 9 the bolt on is the 1050,on the 12 it is a 1250, the others need complete engine dis-assembly and case boring,ups the cost considerably. We use Rev-Perf exclusively and like that their combos are well thought out and matched. What pipe? K&N,open airbox,re-route the breathers. | ||

And installing a bolt on kit is simple,hand tools and a torque wrench.Manual,and you are good to go. | ||

I've yet to see before/after comparisons of these bolt-on kits. What performance increases are realized? | ||

It's according to if that's all you do. If all you do is up the displacement, you may only see a step up in torque, and since horsepower is a product of torque, you'd probably see a bit of a step up there as well. But not as much as you might think. When you combine the bigger displacement with some light head work, you could see a real difference, like over a hundred horsepower with a little tuning. Your best be is to give Revolution a call, they're very friendly and more than happy to help out. | ||

That is the kind of answer I was expecting. I've wondered what those 47cc would really do for a while now. I have the engine on my floor right now to fix some leaky valve seals, so I figured...hey, while I'm in there. However, for the investment required to do all of this, I'll just leave it as-is. Not enough bang for the buck for me right now. I'm sorting out my new suspension in the spring, so maybe down the road I'll look into this... | ||

I'm sorting out my new suspension in the spring, so maybe down the road I'll look into this... Your suspension will do more to help you go faster/smoother than motor work, price wise. Plus you're not worried about longevity of the engine  I asked this a lot back when I first got my bike, and I pretty much got the same answer. Take a sport bike riding class, upgrade your suspension, keep up with your tires, and track days when you can. It's the best answer yet. I do plan on the big bore kit, and stage two heads, and balance the flywheel assembly. Maybe some other stuff too, but I'm not real sure. I'm waiting though, I'm going to wear this one out first, then when it needs some engine work done, I'll try and do it all. Over 70,000 miles and still running strong as ever, and still makes me grin every time I ride. Honestly though, take the class, like Total Control, where they're teaching proper sporting technique. Or a race school like Ed Bargy out on a track. That's how you're going to get the most out of your bike. Then you can come down here and I'll show you round the Southern Appalachian Mountains for some twistie tire shredding  | ||

I've heard the same advice many times, so I'm finally doing it. I picked up a set of forks sprung to my weight with Traxxion AK-20's. Also found a modified rear shock from Traxxion with another matching spring. I'm very much looking forward to the results! I might take you up on that. We're planning a trip down to Fontana in June. This will be my first pilgrimage to 'Mecca'. | ||

To the OP, sorry for derailing...carry on! Haha... | ||

You can't beat the AKs! Good choice, Traxxion are good people.  Blood Mountain US129 (100 miles south of Fontana) | ||

Love that road... Hell, I love all the roads there | ||

1169cc is pricey but (in my humble opinion) - makes this the sweetest motor you could hope for in an XB. HIGHER revving with lighter pistons and flywheels and that is a QUICKER throttle response. My racebike is an honest 103HP, 78 ft pounds on pump gas. I keep compression at 10.5 but in Summer, I run 112 octane to avoid detonation. PROBLEM is that this mod is almost a couple $thou$ more than the 1050 bolt-on. You're also committed to dyno time or learning a data system to tune. | ||

Hey Slaughter, with adding a bolt-on 1050cc kit, and upgrading the cam's, pushrods.. what sort of improvement will this make?.. I'd get the 1170cc kit, however to get case boring in Australia, they're going to charge a fortune to do so.. I don't mind spending a couple of $thou$, if it's going to make a sweet ride... Cheers.. | ||

Has anyone seriously looked at the mods needed to put an 1125 motor in the frame? Yes final drive would need to be dealt with and new motor mounts, etc. but is it possible? Might make a cheaper high power option for those guys that want to go all out. | ||
| Jbolt |
That's a hell of an idea.! Would using the 1125 swingarm make it easier? | ||
| 1324 |
I don't see the point. Aside from the cool DIY factor, you're better off buying an 1125. By the time you factor the value of your XB, the cost of the 1125 engine, harness, exhaust, radiators, and drive, you're looking at the same if not more (probably more) $$ than buying an 1125. Not to mention the frame is different and will require modifications to get the swing arm and rear shock to work. 1125's really aren't that expensive. You'd have a better put together bike with the beefier forks, and very importantly, a larger fuel tank. The XB tank would only deliver a ~100 mile range at best with the 1125 engine. | ||

Top it off, the way the 1125R bolts to the frame VS the XBs motor mounts you would need to so some serious retro fitting to get the 1125 engine to bolt in. By the time you would be done, you might as well have bought and 1125 bike. | ||
| Greg_e |
That's true. But it would be cool to fit one of the water cooled Rotax in there, maybe the smaller displacement Aprilia version. |
