Looking at installing oil pressure and oil temp gauges on my R1 what range do I need on the gauges? most importantly whats the max psi and deg C I should need.
I'm led to believe there is a bolt on each end of the motor you can take out (according to the manual this is where yamaha would test pressure) what thread / adaptor will I need to install my gauges here, I'm looking at a mechanical racetech dual gauge if it makes any difference.

TIA

Andy

here ya go - this will help

The Thread should be an M10x1.0 for the oil temp to check measure the od should be near to 10mm and hold it up to the light to see if the threads are parallel (this needs to be in the oil stream eg the sump or oil cooler) Racetech electronic senders are M10x1.0 as it happens so thats good. The oil pressure is usually 1/8npt so you may need to buy a tap, but this is not a problem because M10x1.0 and 1/8npt are very close so there is no drilling required just run a tap into it. As for pressures I have no idea but Racetech do one to 100psi and Revotec do two one to 100 and one to 150psi so all bases are covered. Revotec are doing a deal on black faced gauges at the moment so it may be worth a ring to them. Hope this helps you out a little

I've got a racetech mechanical presure gauge. 0-100psi and it runs up to 80+ at revs when the engine isn't fully hot. Mines plumbed into the oil gallery. the thread is either M14 or M16 I think and you can get adapters to fit (I got a set that Durite do. Part No 0-523-98. Its a set of 3. 1/8th NPTF to M14, M16, M18.)

Cheers for the reply chaps I'm happy with the 100psi then but what about temp? Is it likely to get over 120 deg C?

Sorry, can't help with that one as I've not got an oil temp guage.

On track with an air/oil cooler ours sit at around 100C, but you really need one to show up to 130/140C for oil though.

Adi do you have any pics of it plumbed in before I remove the wrong bolt I'm assuming you have a 5VY, '05 engine fitted?

I have bought a dual mechanical gauge, I am hoping to attach the pressure to one of the holes and the temperature to the hole at the other end?
All subject to adaptors and room.
The temp has a sealed capillary with quite a large bulb on the end which would need to go into the gallery, do you know if there is plenty of room in there? if not I suppose i'll be making something up from a series of adaptors?
Do you know which of the adaptors you used / can you confirm what the thread is?

The temp has a 3/8 BSP thread ,
I haven't bought the capillary for the pressure yet but would assume they are all standard at 1/8 npt?

I had a look for pictures but it turns out that I don't have any and without stripping off the under-trays its near imposible to take one. If you look at the engine you'll find 2 identical plugs, one on each end with an allen key fitting. I've had a look through my box of odds and ends and can't find either the old plug or the remaining adapters (I bought a set of 3) to find the thread size. The pressure capillarys are normally 1/8th NPT (mine is).
I've no idea whether there's room in the gallery to fit the temp sensor but I'd not want to put it in there. I wouldn't want to risk restricting the oil flow. I'd be looking for some way to fit it into the sump but that would take some modification.

Sorry not to be more help.

I've found the leftover plugs.

The gallery is M16x1.5 thread and the plugs (on my '06 5VY) are sivver, slightly domed with an 8mm allen key hole.

The set I got for the adapter was Durite number 0-523-98

thanks adrian thats great
