X12 motor timing explained??

[c0sie]

My X12 6.5 comes with timing insert number '4', which is X-10'

Firstly, as a total timing n00b, is -10' a higher timing than the +10' that is given when using insert number '-' ??

Also, the printed instructions that came with the motor shows timing number '2' as the standard insert whereas the LRP online manual states that number '4' is standard. Any ideas which is correct?

Thanks

"-" = retarding the timing
"+" = advancing the timing.

You have a standard insert which is marked 0 (if i remember rightly). It's the one that isn't rotated either way when inserted.

The two other inserts, depending on how you put them in, will give you
-10
-5
+5
+10

Hi Chris,

The motor came out the box with insert 'oooo' which is -10'. This is, according to the LRP online X12 manual, the standard factory setting...
However, the printed X12 manual that came with the motor says that 'oo' is the factory standard setting, and that insert is 0' timing.

Im confused though. 'oooo' is equal to -10' timing, and is the same timing that Hupo used at the Euro's. What would minus timing do then compared to zero? Offer more bottom end grunt? Run cooler??

Any answers are greatly appreciated as im totally learning this all here

The main thing to remember here is that the timing it being described as either +/-10 from a known timing point. It isn't +/- from 0.

I think from memory Reto from LRP told me the X12 motors are timed to 40deg and you can adjust -/+10deg from this point.

Thanks Phil.

Do you run the same timing insert at all meetings or do you switch and change dependant on the venue?

Also, do you know what the difference in performance is between the minimum and maximum timing avaliable?

+40' timing is a lot, so to run the -10 insert would be about right.

or forget all the above and run it the way is was intended to be run from the factory!

[c0sie]

Which is what? 'oooo' as on the LRP website, or 'oo' as in the printed manual?

Older x12s came with the oo as standard, the newer ones with the oooo - i think everyone uses the oooo insert now - just stick with that one. The gearing advice has changed a bit as well.

Cheers bud

Do you know what the gearing advice states nowadays?

people tended to run the insert that retarded the timing, which will mean you're running cooler.

Cris buddy

0000 is the more economical and smooth setting were as the 00 gives you a bit more. That will explain why they get a bit hotter with the 00 in there.

All mine came with 00 as standard but have now changed to 0000

How you getting on with the SXX TC have you run it yet??

[c0sie]

Not yet fella, Ursh is still quite ill so I wont be at club for probably another week or two but once I am ill be thrashin that SXX

[TonyM]

I have a secondhand X12 with only the 00. I can't seem to find who sells them - any advice?

Cheers Tony
