Sounds like you have made some good progress.
Are you going to re-instate the orginal autolube? or build something better?

Yes, I am pretty happy with things.

When we made the current no lube motor all the unnecessary internals were discarded and the end of the jackshaft cut off. Bugger don't you just hate that.

We will have to start again and we plan on using a dual line pump from a GT125 and running the oil to the l/h main brg so it can be picked up and feed directly to the bigend like the old style RM125 did. The other line will go to the barrel and oil the piston directly under the exhaust port like on a RGV250.

Why does everybody rip the autolube of as a matter of course?

Downsides of autolube
1. extra weight
2. exra possible point of catastrophic failure is the pump lets go

Upsides

Running premix you have to run the mix for full load so if it needs 40:1 at max revs thats what you use, however at idle you might only need 100:1 (trials bike autolube systems idle at about this) and the extra oil at the lower volumes and velocities can fall out of suspension loading up the engine, hence the rev the crap out of it before tackling anything that requires immediate engine responce behaviour that you see in trials.

I would have thought that a well sorted autolube system was better.
Please correct me if I'm dead wrong on this.

I thought that was to get the flywheel spinning fast to get the inertia needed to flick the bike forward.

I am not sure either, must have been a good idea at sometime, maybe I was a fashion victim...........

BLING you can put a nice polished ally plate over the hole = 10 points in bling

also force of habit and who wants 3 premix bikes and 1 auto lube one

maths
3 premix + 1 auto lube = 2 tins of petrol (and a big mess if I use the rong tin)

**Henk** · 28th March 2010, 07:58

4 autolube bikes = one tin of petrol and you can chuck whats left in the van for the drive home.

Used to have 3 different blends here, 40:1 for KDX, 50:1 for TM and 4 stroke for EXC, yes it was a huge pain and now I have more petrol cans than you can shake a stick at.

the unfinished (and probably never to be completed) MB50 F5 project was going to run autolube for this very reason.

This little beauty uses Auto Lube....

Well isn't that a work of art..
Nice multiple point injection.
Got to love yamahas.

**Yow Ling** · 28th March 2010, 17:58

in the pics it called "little nipper" is that cos its always nipping up ?

**bucketracer** · 28th March 2010, 18:06

More Oil means more power according to this article by Gordon Gennings:- http://www.bridgestonemotorcycle.com...oilpremix6.pdf

oh ohh, I used to keep my old posts so I could cut & paste when I hung out in dirt forums with challenged am-ercans. Saved me extra typing. So from the Best of Dave part 3:

"Oil injection has the advantage that when you run out of gas in the middle of nowhere you can blag some straight petrol from the local farmer.

Many people slag off oil injection which works just fine in zillions of road bikes everywhere. These old world closed minded people cannot accept the risk that the oil pump mechanism will continue to meter oil reliably into your precious engine.

When I discovered (just in time) that my oil level of my old DT200 was not going down I became one of these people.

We meet on Tuesday nights."

So you give less oil to the Italian bike than the Japanese one?!??

Why not just jet them all for 40:1?

That said I run more oil in my 50 as it does a million revs & less on my Trials bike as it doesn't & spends a lot of time chugging.

**Henk** · 29th March 2010, 16:05

TM used to load up and then hit even more like a hammer running 40:1. Not that big a deal really since we were riding lots at that stage and the gas never got a chance to go off.
