Since planting the EA81 into tweety I've constantly tried to reduce the clutter around the engine. This has a few benefits, ease of maintenance/accessibility to components and attractiveness especially for an open engined trike.

The large and heavy iron alternator mount apart from its obvious drawbacks, also caused issues with reaching the screws to the throttle sensor, an item I have wanted to adjust a few times lately when trying to perfect the SPFI running.

So it was discarded. But not before one end of the mount was retained for the main alternator mount. The angle grinder got busy. I also purchased a alternator mount from a minisport retailer.

V-belts have a number system. 10A0770. 10 being the width at the outer side of the belt, 770 being the mm's in length. Ordered 2 from an online shop. They didtn come on time for the Euroa Show and Shine so purchased another one - 11A0775. it proved a good choice. fitted well.

The alternator is a 50 amp job. with no electric windows, air conditioning etc it should be enough. They are made for Toyota Fork lift trucks. Makes 14.2 volts. It was purchased on Ebay for $149 plus postage. However when I contacted the supplier and complained that the two connections (not the main one) were not marked he couldnt supply me with a wiring diagram to make it clear. He said that they are normally for Toyota Fork trucks. My view is that its highly unlikely an owner of a Toyota Fork lift truck would want to spruce his fork up with a chrome alternator. This is not good enough in my view. Turns out the top spade terminal in the T is the one to go to the ignition. The other one is for the dash light.

I'm sure you would agree it is attractive enough.

Bling aside - how's the performance of the spfi going ??

While you are in tutorial mode ...is the length of the v-belt OD or ID ?

mmm OD or ID. well its like this mate. I cut a crap V-belt then kept cutting till it fitted perfectly so its MD. mid diameter. lol

Now the SPFI is on hold for another 2 weeks or so. There seems a little more grunt since the new alternator went on.

But our friend Tambox (Greg) has been assisting me a lot. I now have two MAF's form the states to swap and play. And I have that home made up loom to connect our measuring devices to. So in 10 days or so (got a wheel bearing to fix first) I'll take it to Melbourne for some work and a dyno. Watch this space.
