R1 oil level?
Hi firstly a big hello to the forum users, my name is Al and although i don't own a Locust BEC i do own a MAC#1 bec with the R1 engine. I
believe both bodies are very similar.
My question is: when the engine is cold, where should the engine oil level be in the sight glass?? I've been googling and have been finding
conflicting views.Mine at present is at the lower edge of the sight glass which i think is low, where should the oil level sit when cold, thanks in
advance. Al.

Hi and welcome to the forum!
Don't worry about not having a Locost - probably more people on here have Mac#1's, Indy's, Stuart Taylor, MNR's etc.
All essentially the same thing anyway, just put together a (slightly) different way.
R1 do tend to burn through a bit more oil than other bike engines. I've always gone with keeping the oil at the top of the sight glass with the
engine running. A little over filling will be OK as it'll burn through it soon enough anyway (just don't kick the arse out of it  )
Is your engine fitted with a sump baffle?

On my 5vy 06 engine it is above the sight glass when cold. When its warm and running it is just below the top mark

Welcome!
Yamaha official level is, checked hot, engine off and stood for a few min's the oil should be 1/2 up the glass.
In a BEC install you need an "overfill". General consensus is hot, idling oil at top of the glass.
Has your engine had the breather modification?

Hi thanks for the welcome. Mine does have a separate breather filter, is this the mod?

In addition to the standard breater on the top of the gearbox (and a sump baffle plate) a modification to the cam cover to add an additional breather
is recommended. This can be either a pipe fitting through the cover or using the AIS housings.
There's a description and pictures of the 'mod on page2
here
Gergely's failures are extreme though. Initialy with the standard breather into the airbox, I got blue smoke on hard left corners on track
days. Then with it into a catch tank, I got 1/2lt of oil in the catch tank per 1/2 day. I'm now running the breather mod with both breater piped
T'd together and into a catch tank and the catch tank vented back to the airbox and have no oil into the tank.

OP - you say the car is 2004 but what year is the engine?
You don't need to worry about the breather mods if its a 2003 or earlier engine, its only the 5VY 04-06 and later engines that have this
issue.
Also on the bike when the engine is running the sight glass pretty much empties (engine off oil is halfway up the glass?)
The recommended (Yamaha sidecar team) overfill of ~250ml puts this up to around halfway up the sight glass with the engine running (and just over the
top of the sightglass with the engine off).
Top of the sight glass with the engine running might be a bit too much (could lead to power loss or frothing if the bottom of the crank is running in
the oil?)

Hi thanks for the info very helpful. I believe the engine is still the same engine that was fitted by MAC in 2004, which i'm almost sure is a
pre 2003 carb'd engine. I have topped up the oil as you have said, been out and had no problems with oil being spat out etc so hopefully all is
well. I was looking at getting a catch tank but if i really don't need to then i won't, how can i 100% identify the different age R1
engines?

Mines says 5pw on the thermostat housing and on the side of the motor. Doesn't yours?

02-03 has water pipes out of the cam cover to the thermosat. 04-06 hasn't got those pipes and the stat is under the throttle bodies.

Mine has the water pipes out of the cam cover, so yes the earlier unit.

In that case you don't need to worry about the breather (good call hobbsy)
