Triple Starter Clutch Series 2 Donks (180 & 120).......You know you need one!

O, is it like a one-way bearing used in Automatic transmissions in cars? Any similarity to the Howdi, sadly, not the answer back then. Ian is one clever bloke. Big fan of his Engineering. It looks similar to the kickstarter bearing used in my Husky Automatic, only much much meatier.

We had a tech night recently, which Ian explained the workings. I must of been scoffing a pie or drinking beer 🤣🤣 so I missed the drum. 😳
 
We had a similar talk with that ill-fated gadget, god, it must be 20 years ago, maybe. Really nice bloke, but fundamentally wrong. Ian is so cluey, so this will be a great thing in the long term.
 
Not mine Marty……. Probably too many stabs on the button whilst battery v low and it also had a poxy homemade brass cap instead of steel. Allowed the rollers to jump around to much!
 
The editor of Two Wheels parked his picked-up from the factory SFC triple for years with a destroyed starter clutch, from kickbacks from a poor battery. I heard it told, having your EI set so no spark to start for a couple of engine rotations, and then spark and start allows for less slippage and damage. Apparently, that's for 120s
 
Just put new guts in my ‘79 starter clutch, last looked at it in about 1995, it just started slipping first start from cold. I remember my Ducati had a sprag clutch. The insert liked turning itself back to front, no doubt due to a combination of issues.
 
The death of most Laverda starter clutches is from a weak battery. If the clutch does not get up to speed fast enough it will slip. If not strong enough to turn the motor fast enough it will kick back and ruin the rollers.

This will happen even if you are one of the very few that actually cleans and lubes the clutch periodically on a 750. On a triple there is no maintenance.

Both my 750's have had the rollers and springs replaced 25 years ago and no issues since. The rest of the clutch is still the three roller they left the factory with. They are cleaned and greased every few thousand miles.

My four triples have never had starter clutch problems since they were new.

If the battery seems weak, STOP and don't try starting the bike again until it has been fixed unless you like rebuilding the starter clutch!

I would add that a badly set ignition can lead to the same kick back problems.

All new bits Marty……..

Any other interest from round the Globe…??
Will need at least 10 orders to kick it off.


Series 1 starter clutch on the drawing board. Not as much room in their, so be touch and go!
Stay tuned. 😎
