Title: Tachometer ?
Post by triumphleroy on 01/05/13 at 21:29:52

Pretty sure I saw an Electric Tachometer mentioned on here but can not find reference to such an thing now? Course I am old and slow! Any help on where to obtain and how to hook up appreciated! Did read right on bike that idle speed was 1100 rpm (to keep cam area lubed). Have manuals ordered should be here early next week...

Go to page 8 of the tech section and scroll to tachometers known to work on the LS 650 S40. I'm in New Zealand, but got a fair deal off EBAY from Catalyst Cycles in Tenessee?

Thanks for the reply from New Zealand. Looks as though Tach use is discussed like oil preference? I just want to check idle speed in order to keep cam oiled.

Ive never tried hooking it up to the bike, but I have a dwell tach Ive had since the 70's I can try to hook up & see. I just go be ear,

tri,

Are you lookin' for a tach that you can have on the bike while riding it, or are you merely lookin' for a "diagnostic" tach?

Probably just for diagnostic use! I noticed some where that you used one and put it back in your Drawer. At my age I would forget what drawer I put it in! Just want to know that I have enough RPM to keep the cam oiled, etc. We used to keep the idle up on our old 216 Chevrolets to keep the lower ends oiled. I am just trying to keep riding and having hard time kick starting my old bikes so trying this little beast out. Do not like the controls way out front so far. Course my old 51 Triumph has controls reversed from all these late model rides. I have been riding a rigid pre-unit Triumph since 1957...Probably been riding longer than most folks on this forum been born? Darn I am getting old...

If you are getting old, go to www.avvcc.org click on photo gallery and scroll around, should bring back memories.

You can get one of these cheap, and they work just fine. I have bought several and put them on my trials motorcycle and on my mowers to track the oil changes.

You would not have to mount it permanently - just wrap the wire temporarily around the spark plug lead and take the reading. Since this one says it is for 2 cycle engines - it should show the correct rmp for the Savage which also sparks each time the piston reaches top dead center. If you get one for a 4 cycle engine - it will read twice the actual rmp on the Savage. You can find better tachs that will allow you to set the spark number to correct for the for 2 or 4 stroke spark frequency - but not at this cheap price.

I imagine all youll need is to get it set once & after that youll know it.
I hope Ill be done with constant fiddling with idle speed once I get the Raptor on it, but, Ive been raising the idle speed when its cold & adjusting it down as it warms up over the next 20 minutes or so for years,,
