I did it to move what I felt was a pretty big heat source away from the shock... And I have no idea if it made any difference... that shock failed shortly thereafter... :)

Enjoy your hockey season, man!
(I love snowtime... but here is too short)
Cheers!

Yeah, rub it in! Actually I took my kids to an outdoor rink tonight and they had a blast! I typically wish I lived in a climate with a longer riding season, but things like this right now mean more to me.

I guess if I was a weight weenie, I would quit drinking Crown Royal and beers and join Jenny Craig! WTF was I thinking? (Give my head a shake!).

But if I had a smaller battery, maybe I could fit my 'emergency flask' in there...?!

Thanks NSFW!

I am hoping to do a couple of long-weekend rides this year. My original intent in buying my 640 was to do parts of the Continental Divide and TAT; but with two young kids now, this might become a distant dream! But I want to minimize potential issues in advance, so your advice is appreciated!

Cheers,

Dean

I have just changed the batt of the 990, and I bought also the specified Yuasa, quite costly but high percentage of no-trouble in that department...

Any specific reason for a change?

I was due for a new battery for my 06 625 (converted into a full adventure bike) and wanted something light, powerful and robust for a across Australia trip, all unsupported and remote of course. I ended up getting a Earth X ETX18C (http://earthxmotorsports.com/) which is a very light Lithium battery. It survived the heavily congregated roads, hot desert days and freezing nights, electronic add ons and the bike being dropped every now and again for the 7500 km trip so I can highly recommended it. They do operate differently though so very important to understand this.for example, if the battery voltage drops, the battery will turn itself off via it's internal circuitry and not discharge any further. To protect against this happening, I will install a voltmeter on the dash which I will monitor. The other important thing is to make sure you load test the battery before a trip, regardless of the battery type - a volt reading is only half the story......

I have read very good comments about Shorai batts (and lower prices than Yuasa )

I'm there, mate, and (in my case) I can say that there is no better invested time...
And be sure it will pay back for a life time

Do I sense some hostility here?

Your looking in the LC 4 thread which mostly covers the 640s... These are the heaviest of the KTM thumpers and probably not what your looking for...
The RFS models are probably more to your liking and they came out with some street legal versions around 07...
If you read through this thread you should be able to find some info to help you in your quest...

Have a nice day!

Gunner thanks tremendously for actually responding to my post.....much appreciated. And thanks for the link, I subscribed to it. Thats the kind of info I was looking for...not sure why everybody else felt the need to ignore my question, first time I've ever been to a site where folks didn't want to talk about their bikes, or bikes in general

Oh well, maybe not everybody here is the "friendly" type.....

Anyway I had no clue where the 640 fit into the line-up...hence the questions. I have no real idea what KTM offers dual sport wise, and was hoping you guys could help me out a bit.........and YOU did Thanks again

sorry you felt ignored.

you're too impatient and demand quick response!

lc4 is not the bike for you, get a 525 exc.
