fuel is about 6ltrs. bearings are standard. i'm 99% sure the rear bearing is fine as there isnt a leak from the backplate at all, which iassume would happen once the bearing stops sealing.
i used a heat cycle method at the default needle settings. gentle running on bitumen for about 3 mins at 200ish degrees farenheit(sp) then stop, put piston at bottom of stroke, let cool to about 85 was 65 ambient at the time. did this 5 times. then did 3x 5mins at same needl settings same cool down, but with a bit more throttle, temps got to about 220. then i started going fairly hard, but still with the stock needle settings for a few more tanks of fuel. finally i went as hard as those rich settings would allow for another few tanks, and then i started leanin the HSN in 1hour increments till i got to about 2.5turns i left the LSN as it was (flush) as the engin still seemed lean down low, in fact i even tried making it richer, but this just caused it to not idle.
i changed the glowplug after break-in but not since the last few tanks where its been playing up.i figured that becauseits idling fine and when it runs well, it is running really well, that wouldnt be the problem.
i think i'll just go ahead and change the bearings over, hopefully they're the problem, im in australia, so will any engine bearings be ok. on these forums there are about 5 brands that people are saying are the best, i'm thinking its just personal preference. and availability. what sorta price can i expect for both bearings?
i use the P3 plug.
