1125 "Regular Maintenance"-Holy Crap!

[Rogue]

To change the spark plugs on the Helicon engine, you must drop the engine and rotate.

WTF?

Bring on the updated Firebolt and Lightning and KEEP the Thunderstorm V-twin.

That seems like a miss engineered bit to me.  I forget, what's the angle of the 1125's twin cylinders?  I believe it's a fairly narrow angle.  I wonder why one couldn't get access though a seat and airbox, if it is a narrow angle.  

Speaking of "Regular Maintenance" of the Helicon, does anyone know how frequently thevalve checks are required?  

[R Doug]

Thank you Google...

It's a narrow angle twin:

Valve check intervals are 12,500 miles (20,000 Km).

I'm very impressed with the power figures for the engine, but dropping the engine for regular maintenance does not sound plea$ant.

How often do you expect to change the spark plugs? honestly?

Good point.

Less than a year ago there was a love fest (clicky) about the simplicity of Buell design.

Obviously there would be some changes with the change to the new Rotax engine. Do you really have to drop the engine as in remove it from the frame? Or does one just unbolt some of the engine mounts and rotate it forward a few degrees?

I believe the plugs need to be changed at the valve inspection intervals.

I have worked on this particular 2008 1125R myself.

I can tell you that Buell did NOT do its homework on making the bike simple to work on.  As a matter of fact, they took two steps back as far as maintenance when compared to the XB models.  Buell rectified some of these little issues in the 2009 model but those with 2008's still have to deal with it.  Another reason not to buy first year models.  

If dropping the engine and "rotating it" is required, I'm thinking you will need at least an overhead hoist to hold the chassis in place while the engine is dropped and held by a scissor jack.  The only consolation is that the Helicon has finger follower valve operation.  No need to remove the camshaft to change shims.  

The XB models still wins out on low maintenance.  That is where the heaps of praise were meant for.

If? Do you have to drop the engine completely or rotate it in the frame? Anyone know for sure? Thats what I was asking.

I'm aware of the differences between the models.

good thing is there are finger followers so you can swap shims easily.

While I haven't worked on the 1125 it's a common practice to have to do that on the fuel-in-frame Buells.It's not as big a deal as it sounds like.Use a jack under the muffler(it's marked with a arrow that says "jack/lift point" usually located at the clamps) to hold the front of the engine.Undo the front engine mount so the engine can drop.use the jack to lower the engine until you have access.You may have to remove/loosen some bodywork to accomplish this.Takes about an hour start to finish.You oughta try a top end on a fuel-in-frame Buell.The rear cylinder will get a nun cussing.Hell getting a spark plug in the rear cylinder is a pain.

P.S. Buy a manual.Saves much time and headache with Buells.

[DogBoy]

Thanks for the explanation, thatguy.

[thatguy]

It's never as bad as it seems with the Buells.They aren't too bad to work on.The problem is packaging an engine not designed for a modern frame.Actually any perimeter frame bike is an involved process.Do a valve adjustment on an inline DOHC four in one.There are some fasteners that beg to be replaced with industrial velcro!Fortunately they don't need as much work as the older bikes.

[Bueller]

One owner told me that there are no jacking points on the 1125 muffler, so he's buying a headstem stand.  I'll have to look it up in the manual.

The Thunderstorm engine spoiled me.  Valve checks?  F-that! Also, the low end grunt wins every time in my book.  I took a demo ride on a Triumph ST and Tiger last week.  Like the engine but the whine was a little too much for me.  I'm staying with Buell...

Agree about the manual.  Let the factory guys figure it out before you screw something up or disconnect a bunch of stuff you don't have to.

The XB rear cylinder spark plug, I learned from the BWB boys.  I use needle-nose pliers with a 90 degree bend near the ends.  Works beautifully.  For the wrench, I use the plug socket with a U-Joint.

[thatguy]

I torque spark plugs.

[Rogue]

I can't see how you can do that with the front spark plug on the XB.

.... which are among the reasons I'm replacing my thrashed FZ with a Buell.

I love how the twins deliver power.
I love how low-maintenance Harley engines are.
I love the streetable power they offer. I don't need a 150+ MPH bike, but I do need one that gives me a flat torque curve in any gear at any RPM.

Believe it or not, I got really spoiled by my Harleys in favor of other, "better" bikes.
