Hi sad Punk,
I am interested in the header, but will it fit the older 41 DRs made in 1990?
Mine is a SL model that has the Big750 body but the 800cc engine.
What's your bike's make?

Now on to the lithium battery part.

I got a Shorai Lithium ion battery (the biggest model- LFX18A1-BS12) and it won't fit into the battery compartment if I were to put it in the right side up.

But there was plenty of room if I slot it in side ways, with the -ve end at the bottom of the battery compartment and the +ve end at the top.

Cranking power is significantly better when compared to the lead batteries. I got at least 12 good cranks out of it before I noticed a drop in power. But after that the battery got weaker fast. Got another 6 or 7 cranks before the battery was too weak to do a proper crank.

The standard lead battery can only give 6-7 good cranks before it runs out of juice.
Bad news when the bike won't start and I was troubleshooting the carb.

I ended up push starting for every turn of the screw.

PM sent Silent Hunter.
The shorai battery is something im considering buying for one of the bikes. Let us know how you get on with it. Did you buy thier charger for it too? I believe you cannot use a standard trickle charger on it?

I got mine from the local dealer.
I goggle the local dealer address and number from the Shorai main website.

The guy just started business in Singapore and I was his first customer!
The dealer Kelvin wasn't ready for business until April. But I ordered mine from him anyway, so he did an early bird order for me and a few other people who called in and gave us a 5% discount.

If you are getting a Shorai battery, it is best to find a local distributor. That way you get the 1 year warranty after the purchase.

As for the charger, I just bought a generic one from this guy from eBay.

http://www.ebay.com/itm/320715017864...84.m1438.l2649

Used it once to recharge the Battery after the battery went flat from my experiment on how many times the battery can crank.
And once again after I tuned the carb. Works ok so far. Charging time is a bit long. Roughly 5-6 hours for a flat battery. 3 hours for a partially discharged battery.

If you are getting a non-Shorai charger make sure the charger DOES NOT have the de- sulphurication mode.
That mode will charge the battery above the safety voltage.

Anti Gravity, is the lithium battery I use, its about at least 50 percent smaller than the stock one and about a third the weight, it has about 130 cranking amps from memory.
The instructions say that the battery operates best if the bike don,t start to leave it a few minutes before cranking again as the battery will heat itself and give out more charge the warmer it gets the better cranking .
Silent Hunter if your battery and the size of it rather large too, and starting to die after 7 cranks maybe you got some troubles with starter motor brushes in the very near future . some thing don,t sound good to me .

Not a chance Robmoto.
I replaced the entire starter motor in 2010.

The lead battery is the problem. From what my mechanic told me, the Yuasa batteries were no longer made in Japan. Thus, the low quality. Farther more, the batteries were old stock and probably had corroded lead plates when it left the warehouse.

By the way, the Shorai LFX18A1-BS12 is the biggest one they got. It has a whooping 270 CCA (Cold Cranking Amp)
Width is 2mm broader than the lead battery, but length and height are much much shorter, so it can still fit into the battery compartment by rotating it sideways.

The Antigravity lithium 8 cell 240 CCA is what I use in my 800 yellow bike and found it to be very good so far my mistake I did say 130 CCA my mistake.
I was using the Oydesy PC 310 which is 100 CCA a bit gutless really.
I bought a motobatt MBTX14AU and found these are good for cranking, bought one locally they wanted 150 bucks got it for 130 thought this was good it has now shit itself after 15 months maybe old stock or something .
I now have found a place called http://www.batteriesdirect.com.au/
and they sell them 70 bucks 12 postage so I thought I will try this brand again as it did crank the big over quite good , for any one else they sell or the different brands and the prices is right.

Antigravity

Rob, have you already had a chance to try out Antigravity 8-cell battery in cold weather morning conditions? I mean temperatures around 0 degrees Celsius or 32F and the bike been standing outside whole night.

Yep have tried it in cold weather -5 C mind you my 800 has pumper carbs, just full choke 2 hits on the throttle , it only turns over twice and bingo she,s a goer, I have been using this battery for at least a year now, seems just fine to me.
I have a delvic battery in the motard, It was in it when I bought it, I have had that bike for about 4.5 years so it could be maybe 6 years old and it cranks real good but it is a full size one and heavy, when it shits itself a Antigravity will take its place even though I have a spare PC 10 sitting on the shelf.
What ever you do DON,T by a roadstar normal old lead acid battery there CRAP.

Lucky you have a HUGE body . I bought one and put it on a standard shock and found that there was too much rebound for in the bush.
But I do run one on my orange 750 that I go away on riding on tar only with all the camping gear grog etc, and found it good.
trying to put a pic up for you don,t know if this will work

Nice.....

Great looking bike you have Rob. I'm 6'6" tall so the bigger the BIG the better

My rebuild is on here :

http://www.drbig.info/forum/viewtopic.php?f=7&t=1239

It runs to seventeen pages so far, and that's just taking the rear wheel out
