A forum for owners of Yamaha TTR250 trail and enduro bikes!

I can't think of anywhere else that would leak acid so I think you have to accept the fact that the battery is leaking and will need replacing before any more acid damage is done Mike 

I know pre-Christmas is not a good time to be spending out.

Best source for new batteries I have found is just up the road from me so I don't have to pay p&p

Stick the voltmeter on it and press the starter, i'm betting the cranking voltage will be 4 - 5v .

 I am guessing that is bad?

Logi you were right cranking voltage as low as 5, no wonder it won't turn over. I have found that the battery was leaking from the press on top, which is meant to be a sealed unit. Thasnks for the help. Mick

Logi was right, the cranking voltage was as low as 5, no wonder it wouldn't start. I have managed to source a Numax YT7B-4 from a company off Ebay called 'Batterybayuk' and with delivery it stands  me at £26.94. It will be with me on Monday, as I rang them direct to make sure I caught todays post.

Now that is a bargain!!!!!

Firstly - get it to the top of a hill.

Secondly - face the bike downhill and put it in second gear.

Thirdly - heave the bike, in gear, backwards. This turns the engine backwards until the piston is at the top of the stroke.

Fourthly - Ignition on, if engine cold give it a bit of choke, petrol tap on then push or roll the bike downhill with clutch disengaged but still in second gear.

Fifthly - when you are free-wheeling at a decent lick ease the clutch out fully. Momentum will turn the engine over quickly enough to start it running.

If it doesn't work then push it back up the hill and try again.

Best bet is to get a new battery if yours is not holding its charge. 

TTR battery (Numax YT7B-4) from Positive Batteries do a quick turnaround at a competitive price.

A kickstart option was available on the metal-tanked TTRs and I have had quite a few go through TTR Towers with them fitted. All blue plastic-tanked TTRs have dual start.

I occasionally get a kickstart kit when I break a "blue" TTR engine for spares. Very easy to fit - see http://ttr250.com/TTR_retrofitting_kickstart.htm

The Polisport headlights are defintely road legal in the UK.

I hope your battery is OK. Sounds odd though.

ttr fan could you message me at (saharvey@hotmail.co.uk) when you get a kick start kit in, as i would be intrested in getting one asap,

dont like the head light i got on as not very secure and only got one bracket on each side and move arounds abit.

abit odd about battery, doesnt help that head light comes on straight away when you turn ignition on as that zaps abit of power.

might have to order one of those polisports units.

You are on the waiting list for a kickstart kit!

The easiest way to save the battery is to cut into the dip wire (yellow I think) when you fit your new headlight and put in a switch such as this one - http://www.ttr250.com/TTR_extras/#light_switch 

The headlight always on is a safety plus though...

Brian

I run a Numax on my 325 and it peforms well with the additional load - good deal on eBay here

Brian

I'm using a Motobatt battery now & it seems like it has heaps of go. Lasts ages cranking & plenty of power. We will see how long all those good things last

Buy a low ampere solar panel, Thats what trickle charges my triumph thunderbird over the winter,works a treat but make sure its low amp otherwise you might boil your battery.

Look for something 1-1.5 w,no higher if you can get one less than 1 w even better,somewhere on the web is a formula for working out the correct charge rate according to your battery amp hours.

Mines actually 1.5 w but it only kicks that out on really sunny days, the uk is not sunny most of the time and therefore I get away with it as the charger is usually putting out less than the max.

i have a fully charged 12 volt car battery removed from the vehical. If i were to remove the TTR battery and connect the  

postive to positive and negative to negative ( like a jump start ) but both batterys  out of the machines. would it work as a trickle charge over night  topping the TTR  battery and keeping it healthy.

I did A Level physics at school which included a lot of electrickery stuff but I have forgotten more than I ever learnt!

Thinking about your question, I don't think anything would happen as the TTR battery isn't going to draw current from the car battery - all will be at rest surely?

Brian 

hi can anyone help me i was stripping my bike down today and cleaning it. when i noticed the battery negitave was going to the red wire at the top and the positave was going to the bottom look at the pic attach is this the wrong battery, and if it is wrong will it of done any damage.         thanks paul 

The conventional way to mount a TTR battery is with the positive terminal at the top attached to the red wire.

whats the code for the right battery please

i only started it once when i bought it, it started ok and runs fine. what do you mean Could the polarity of the battery have been reversed in some way. wat does the red and black wire go to thanks paul

Hi Paul

The pic below shows where the battery leads go on the solenoid.

This looks to be a good deal on a battery. You can check the dimensions against your battery.

I hope that helps?

Brian

Hi could anyone recommend a decent battery at a decent price to fit my TTR250 ENDURO also would it be a good idea to fit a kick start to my bike.

If you want to go cheap, I'd recommend a Motobatt. I have had one for a year or more now and all is still A1. You can find these batteries on eBay for around $55.00- http://www.ebay.com.au/itm/DRY-CELL-DRZ400-SUZUKI-YAMAHA-TTR250-BATTERY-USA-AGM-12V-MOTORCYCLE-YT7BBS-/251372461131?pt=AU_Motorcycle_Parts_Accessories&hash=item3a86f75c4b

Fitting a kickstarter would be a great idea but realistically will probably never happen as they are not available from Yamaha anymore TTBOMK. There are a few kits online that I saw for around $450.00 AUD but at that price it is not worth it, although it seems to be the going price for them.

Hi there all, I would like some opinions to confirm what I think? 

So my lovely TTR starts first time every time on the kick, but trying the starter button just struggles to turn. So I did some checks this is what I found...

1. Bike running more than enough voltage and stable going to battery - 13 volts ish
2. Bike stopped ignition off - 12 volts ish on battery
3. Turn ignition on and voltage drops to 8.3 volts straight away before pressing anything
4. Press starter and voltage drops to 6 and then returns to 8
5. Ignition off only 9 volts left now

I would say that the battery is dead on this testing.. Why would a drop from over 12 to 8 happen straight after switch on??

Surely 8 volts is not enough to turn over the bike?

Any advise or ideas from you helpful people on here would be great..

Cheers

Danny  

PS Horn does not buzz at 9 volts LOL
