Howdy all,

Just thought I would share my joy at seeing/hearing my motor up an running for the first time in 10 weeks. Its just about finished (little bits to go on) and should have it back this weekend - YAY!

1000kms of running in and then another 3000 of gentle driving and we'll see how it copes with 18-19psi. Will keep you updated and hopefully have a dyno sheet in a few weeks.

Cheers,

ken

Pretty sure thats it.

Its going to be really frustrating running the thing in. Might have to set the pfc for low rpm and "lose" the hand controller for a while, aarrgghhh.

hahahhaa 4sure!

there are so many variables with running in engines - maybe talk to Cruisliner or Sydneykid about it?

thats a fair sized list there.......... well done and best of luck.

have a read: http://www.mototuneusa.com/break_in_secrets.htm (warning: for bike engines!)

Advice lads on running in? Much appreciated. This is the first motor I have had to rebuild, I'm pretty surprised it didnt happen sooner. Hopefully never have to do it again either! Bloddy expensive.

Well done on getting it finished, it's such a great felling to hear it burst into life the first time. :P

I have used the same basic running in process for lots of years and on many engines;

Castrol GTX (the basic no frills mineral oil) with new filter.

Run engine for about 1/2 hr or until well warm.

Change oil filter. Engines can have particles in them that acccumulate during the build/maching proces and they need to be removed from the engine ASAP, these are caught in the oil filter. If you leave them in, the oil filter can get blocked and so it will be bypassed ie; no filtering.

Check the basic tune on the dyno or on the road with portable lambda sensor.

Drive to Bathurst and back, around 500k's, lots of varying conditions, up and down hills, freeway, long climbs etc. Don't rev the beegeesus out of it, gentle but firm, change throttle openings often, no slogging it in high gears with lots of throttle. Much better to load it up with partial throttle openings going up hills.

Drain the GTX and remove the oil filter.

Refill with Castrol Edge 10W60 and fit a new oil filter.

Do leak down test, if OK then final tune on the dyno.

Go racing

:D Cheers :(

for your info - 5 parts to the running-in of an engine, plus his advice makes sense.

Im not liable for blame if she blows! - but my bike engine loved me for it :P

Honda motorcycle engines rev to double the rpm of a Nissan RB

The tolerances that a motorcycle engine is built to are not the same as an RB

Honda motorcycle engines are not usually turbocharged

Don’t pussy the thing, lots of varying load is good, but not lots of rpm or boost.

:P cheers :D

I agree - not that that means much.

Lots of varying the RPM, ie the load on the engine, is the way to go. Never let it 'idle' drive, ie sit at 60kmph for 5mins at 2500rpm; vary the load.

    • This one?? In other news: I cannot tell the difference between my red MX5 with the silver grey hard top......... and the Ferrari 599XX EVO, they might as well be twins, well.......apart from the big wang hanging off the back of the Ferrari...🤔🤣, without the wing they are identical   
    • Turn it into the pride flag 
    • I think you'll find we're confused about what you were trying to do and how you were doing it. I would have thought that block rigidity was something you measured while loading the block in beam or in torsion, and that you would do so before and after grout filling, to see if putting material in there created a "composite" construction with the expected rigidity increase. Notwithstanding that the true function of grout is less about gross rigidity than local (ie preventing bore deflection/splitting and tying the bores to the main bearing locations a little better, etc etc). It is nearly impossible to follow your description of what you've done without closing ones eyes and making "aliens" hand shapes in front of oneself to try to follow the manipulations you've made. It's still unclear to me what you were trying to prove.
    • Not a fan of "racing stripes" really, I've seen a few done, with different styles of stripes, but no, not for me Although younger Mark probably would have thought differently about them
    • The correct answer is body colour. Admittedly it does look pretty handsome as-is in grey.
