What's the best battery for the hard to start klx250..... The one that's in it now is from battery source made in china...it barely starts it before it kills it...once it's warmed up all it takes is a bump from the starter...but cold cranking I need all the battery I can get...thx

 

Shorai Lithium batteries are very poplular. I have the smaller of the two recommended, but the bike is just a hard starter sometimes. Mine is anyway, and others post similar problems. My DRZ SM, in contrast, also has a shorai and starts first time, every time. It also sits outside, under a deck with a cover. Year round. I mention ALL this, because the battery may not be the issue with the starting problem.

 

replacing the battery did nothing for my hard start (have a shorai lithium iron battery...it is the more expensive one too)....but, valve adjustment cured it all....before you start replacing the battery, do a valve check...

 

Sharai battery helped me with cold starts. Holds a higher charge than lead acid batterys.

The bikes a 2006 but only had 900 miles on it....still like new...it was hard to start when I bought it and figured I'd have to rebuild the carb....until I looked on this forum and saw we're its plagued by hard starts....I've read of drilling out the starting jet...pulling the factory cap of the low speed jet and setting it at 2.5 turns...all of which I may end up doing. But first I'd like to see if a good strong battery will help...the ones that's in it ain't much....the bike runs like a top after it warms up....I put some sea foam in the gas and using non ethanol gas....I have an idea the reason for the low miles was the hard starts...where's the best place buy batteries...thx

 

I dont want to steer you wrong, Iwould recomend drilling the starter jet first.

The shorai helped me turn the motor over when it was cold out. With the big bore, the lead acid only lasted a few tries before running low, if it was cold out.

Which one are you using the small or larger one ?
My bike starts a little better since the valve check but still takes half a minute or so cold (not constant cranking). Don't know if I need the bigger one.

I think it's the 'big" one. ?? $143 last April at RMATV

 

+1 on the Shorai Battery...I installed one last year"I didn't need one"But glad I put one in...Lots of power n Amps..Plus small .Light..win win

 

My bike is an 09 the stock battery was failing when I bought the bike as the dealer must have let it go flat. With a tender I got 3 yrs out of it but it was always weak. I just replaced it with the cheapest battery I could get on ebay as I figured I'd get a fresh one that way. So $24.99 delivered to my door without exchange I got a battery that is much better than my old one ever was.
