Big Bore Electric Start Problem

Johnny Tran

New Member
Hello guys, I'm new here and I only speak english so please help me if you can. My engine mods are:

UMA 62mm Block
30mm Carb with bigger jettings (not sure what size)
BRT CDI
Vixion Stage 2 Cams
AHM Pipe (newest model)

The problem now is that my bore is so big that it's hard to fire up using the electric starter so I have to frequently kick start but even that's a pain... My mechanics say that it's b/c I'm in high compression but I don't know what this means. Someone please explain to me what I can do so that I may use the electric starter again since I will be getting a full body fairing kit that will cover the kick starter (ie: Will a Racing Ignition Coil help??) Thanks!

you can't do anything but kick start your sniper to life. the stock electric starter is too small to crank over your present setup. its not like with the big displacement mio wherein you can replace the starter with a greater cranking power electric starter. the recess of the center case of the sniper where the starter lies in is even too small to accept a bigger starter unless you are willing to make some modifications to the center case. i have been looking for a electric starter that can crank a big displacment sniper for 3 years now but to no avail (at the moment). maybe electric starters from sportsbike may fit (some forumers out there might have experimented??), but for now enjoy kick starting...

7amps as well bro
just like with mio, if the stock starter with a bigger amperage battery would be enough for a bigger displacement engine then there would be no reason to place a higher cranking starter once the displacement goes up. its not just the battery but a greater cranking e-starter.

i already did, but it didnt work well with my 200plus cc daily driver. the starter gave way. need bigger starter.

i installed a larger radiator and fan. its a three year old engine with about almost 7k kms on it. the longest distance it travelled is when i went to manila from legaspi about 600 plus kms. and back. i weigh 205lbs so i enjoy more of the torque than the full throttle speed. torque for overtaking and mountain passes. my old daily driver. still reliable after all these years of riding. actually the engine kit was sold to me by hispeed three years ago. its a setup they used at the malaysia sepang circuit. so they said it can be used for daily use. the block was built up in the sides to create a bigger area for coolant to circulate around the bore. the sleeve which is steel was built sturdy so no worry of sleeve rocking from side to side. a longer conrod was used for greater conrod to stroke ratio which improves reliability due to less cylinder wall rub as compared with s shorter conrod. 22in 19ex head, 6.2 hispeed cams, hispeed valve springs and retainers, wide ratio transmission, 28mm oval keihin carb. so everything was set up on the mild side and not on the wild side. 02182011198.jpg02182011199.jpg02182011200.jpg

Doc,
Sry, forget to mentioned, its tailored fr LC/Spark wz big bore...

vanjo,
There's no effect to the engine block,may be the starter moto gear,it got worned after frequent force kicking...
it is advisable to silmulteanously usingng the elect strtr n the kick strtr,just to release the burden on the strtr moto.

Vanjoo,

Fr the time being, like what doc mentioned,you hv to use yr kick starter,changing batry is just a short term solution cos when the batry is weak you still need to kick start, just wait till the hi pwered starter moto, at the momnt dont change anything...thats the price you got to pay when you used big bore.all you need is a strong leg...kih...kih...kih

right you are...if kick starting becomes second nature you wont be looking for a e-starter...hehehe. have you ever tried kick starting a 4 stroke motocross bike? its like dat. just keep on kick starting until the engine runs.
