How about changing the battery to cope with your usage? I have changed to an Odyssey battery on my 97 Thunderbird - brilliant. Have not had to worry about charging for the last few years with it. Got it from Carrot Cycles in Lincoln - they deal with classic brit bikes rather than modern Hinckley so should be able to advise better for you. They advertise in the TOMCC Nacelle magazine.

I wish my T140D had electric start ;-) Personally, I would not de-S a T140ES.

Good luck,

I'd have thought that a bigger battery and getting the timing spot on would help tame an ES. I wouldn't change it as it must be easier to just not use the starter if it offends you, but changing the bike (which is quite rare) seems a big step.

I assume that the ES bikes were EI - if not then maybe changing to EI is worth it for the lack of slippage timing wise. The spray clutch was notorious for failure and they were hard to find but I hear that reg Allen has a stock

I would think that the ES models are reasonably rare, so worth keeping intact.

i did away with the electric start on my t140es, you will need to change the timing gears as well as the casing. after stripping the timing gears 3 times i decided enough was enough with the electric foot.

If you are having a problem with your starter due to a weak battery I suggest you downshift and run your RPMs at a higher level in order to acomplish a proper battery charge. Next problem you gonna have is Ignition due to the low battery if you continue in your current manner. If I remember correctly the battery in an Estart was a Yuasa YB14AL2.
Now regarding your dislike of the looks of the Estart cover. It seems to me a silly thing to purchase a bike you dont like the looks of but what do I know? I would love to have a Estart in my collection. Fell in love with the Estart Executive model first time I saw its picture. Rest assured if you continue to use the factory Estart you will get to find out what it takes to change the cover. From what I have heard there was an Estart problem that caused interesting results. Maybe you should sell your bike and purchase a Pre Estart

I can vouch for the interesting starts or rather non-starts on my TSS. . . which is now a "KS" only.
