"Hard starting" (Reason: Cams)

By MF battery is still working (8mos old) but cannot do the job to start my bike.

Thanks

ice tried looking for a bigger battery back then, checking its dimensions..
then i realized the battery compartment area is too small for the bigger
amperage batteries.

if you guys know a smaller dimension battery with bigger amperage
let us know...

hi,,,my friend in banga using 2 batt, one is 4 amp and our stock 5amp, make it parallel connection.(all in all 9amp) wondering where did i put the other one ? inside his airbox. the other batt is quite smaller..it can fit inside the stock airbox.

@ traxx

What cams are you using? do you also experience hard starting on your sniper?

@g-tomahawk

this a nice idea bro! thanks for the info.
so far im ok with my 5amps battery.

moving the stock battery from top to aircleaner box will lower the central mass of the bike.
that will improve handling.
plus the old battery box will now become your UBOX!!!! :D

will try that bro :)
lets see if it will fit.

This is a nice idea. I will also try to put the battery in the airbox. :)

with out airbox is easier fit , with airbox u can fit 3 amp batt without hassle inside it
i rem from this tread also one forumer said best stabilizer for our bike is higher amp .:D

its d product of following all your tips here in t135. so far all set up with our bike all 3 of us (rowan , NOI.357 and frankie)were same and proud to say all came from t 135 forum tanx esp to traxx and other forumers. all we do is try and test what had been suggested here and see d best result.actually watever we got from here we suggest to our mechanic and he'll jst follow it and good thing it all works.

@traxx one of my friend use rextor by adding batt he said he got better performance

tips from traxx is tried and tested but beware once you got it you will be addicted to it:D

sorry for the OT:)

what is the recommended resistor value if you go for a 7 amp battery?

One of my considerations is the koso digital guage.. too much amp might short it..since the power is direct from the battery.

sometimes I go beyond 13 volts is this ok? would that change once i change from a 5 amp battery to a 7amp battery?

thanks

I think the issue here is the starter motor and not the Battery
To explain this further
1- Stock Starter motor is designed to start an engine with 135cc displacement, stock cams or in short (No kalikot)
* To Start our bike with Modified engine with a high lift cams, the starter need to kick much harder because of the high compression.
Resolution: - Have your bike check, ipa LOCOMP mo
- Have your stock starter rewind to make it work with your high comp Cams
Advantages/Disadvantages of Rewind Starter( Logical thinking )
Advantages - Will start your bike easily if the only issue is high comp(other issue that will now start bike, not properly tuned....etc)
Disadvantages - If we are using stock or 5amp battery, pretty bump or almost near the end of its service....If you cant make it start from 3 to 4 times, 80% your battery is drained and you have to kick it to start

=====================================
Anyways, Ampere is the Constant Current the flows through electricity while Voltage is the current/power needed to make something work.

Heard a lot of question regarding batteries...Why does my battery doesnt work? I already tested it with a Volt meter and it gives me a reading of 12.5volts...The answer is, the designed ampere for the said battery is weak already that's why anything that you will attach to the battery wont last or wont even work if it has a higher wattage....

HTH

Thanks pre for explaining.

So regardless if you have a higher ampere of battery this would not make any changes on how your bike will start right?

My bike can start "sometimes" using the electric starter, but most of the time not. like 1/10 chances. I guess my battery became weak so fast. It's only been only 7 mos. Before it used to start smoothly without any hassle despite that it's block and cams were modified.
I already found someone who can rewind the starter motor. Info came from Gerry. 850 bucks. near his place.

OT: most of the people who loves you are asking why you not reply on sms. Ü

very well said....anyway mings what brand of cams are you using? lift?
Like what paul said CMS cams. Performs really good. Bike starts really hard.

his using cms cams like mine.. the battery idea came from yoko hehehe.... so he try to get other opinion
Yes, I would like to get other opinions from folks who have the same problem. Good thing I did not buy anything yet because I would like to get a lot of inputs before making a move.
