Can anyone help me with a problem with my Triumph

Post by Scotty4545 »

Hello new here and was advised to try this section for some help. I have, What I think is an electrical problem with my Triumph Speed Triple 06.
The problem. When I try to start the engine the starter cranks the engine over very slowly a few revolutions until I release the start button. Like as if I had a flat battery.
Now a little history on the bike regarding this problem, please bear with as this may be a little long winded :D
Not long after purchasing the bike I had starting problem. When trying to start the engine the starter would crank and make horrible clanking noises every so often and then start. Bike being new to me and being a little careless I continued to use the bike. Until one day trying to start the engine after a few failed starts the starter motor would just spin not engaging the engine.
After researching and finding out I had buggered the starter, idler gear and sprag clutch I sourced parts I needed from used bikes and fitted them. Fully charged battery and the bike fired up perfect. Bike was starting great for a while. Then one morning the crank speed was slow so I aborted the start as to not bugger the new starter and sprag again. I bumped started the bike rode to work in hope it was a low battery and the trip would charge it. Crank speed was slow when leaving work but had a jump pack that ran off a dewalt battery and that started the bike fine.
As this bike is my daily ride I used the jump pack when there was no hills around to bump start it until the starter solenoid would just click. So replaced that! Along with a brand new battery I also upgraded the guage of the wires for the starting system and the bike still will only crank the engine very slow. Will only crank fast enough with assistance from a jump pack.
I have cleaned battery terminals, engine ground terminal, clutch and starter button switch swapped relays around and changed fuses to no avail. Anyone have any ideas??? PLEASE :((

Ok, just some initial questions as I'm not following.

Have you tried mains charging the current new battery when not in use (each night)?
Have you tested the voltage at the battery terminal with the engine running (so have you confirmed the bike is actually charging the battery)?

Hi jug, sorry if a little unclear.
I have actually bought 2 new batterys now the 2nd being a more expensive better brand as advised cheaper brand batterys can be hit nor miss anyway. Yeah I have fully charged them using a bike battery charger to it will not charge anymore multiple times while this has been happening.
They hold good charge around 12.9 volts on the multi after being unused for 24hrs
The bike seems to charge the battery 14v at idle and a slight drop when revved below 4000rpm also I don't need to charge the battery when using the bike daily all other electrical parts seem to run fine lights, fuel pump, indicators, and horn never show signs of low battery

So I guess the only thing you haven't done is opened up the starter motor (or replaced it)?

Starter motor is only a few months old so assumed it to be ok would not be worth pulling and stripping?
