Re: B25 - what to do while the primary cover is off?

Make sure the rotor is still in one piece and the crank nut is tight, the mainshaft on the B25 is soft, not hardened like on the built up cranks and the shaft splines can be eaten if the nut loosens.

Re: b50 bottom end

Welcome Richie <135

Minety +1 on PES.

There is a RAL match to Dove grey, should be googleable, it is somewhere on this site I think. If you go that route make sure the finish is durable as it will show up dirt a lot more and the extra cleaning required will dull the finish eventually.

Re: Crank Big End Nut tightening to 200 ft lbs

Its a very thin nut so I removed all the lead in chamfer on the socket and had to reduce the OD as well to ensure the socket fully engaged the nut.

Re: Crank Big End Nut tightening to 200 ft lbs

Alpha is shut due to death of owner, the 200lbs is correct for B44 and B50, I stick the crank in the lathe with the flywheel in the chuck. I tried the work bench once but it lifted off the floor before I got to 200lbs.

The Premier comes with an anodised slide, this is to cure the galling issue, plus the aluminium premier is cast aluminum alloy, not zinc based monkey metal. Lighter and less wear.

Re: B44 MX Motor

The B50 pump does not provide increased flow over a good B44 pump, the gears are exactly the same as the B44 but the body is cast iron not zinc so the body will not distort and the pump seize or leak profusely as the zinc one can over time. The B25 has the wider feed gears which does increase the fl...

The chain line did change but later when the circlip appeared, on my B44 with the 428 chain I used a C15/B40 19 T gearbox sprocket and it all lines up. The C15 B40 rear wheel sprockets are different, you need to fit a B40 one or the chain line will be out by some way.

About 5 psi or less in the feedside, if the pump is worn badly the filter will stop the return flow but that's well past when the pump should be refreshed.

Re: B44 MX Motor

Wrong way round MM, feedside gear is narrower on B50 compared to B25 as with no back pressure with roller big end if the wider B25 gears were used the scavenge side can be overcome and the sump overfills. Maybe a B25 pump would work with the OPRV blocked, may try that on the next engine.

Re: No Ball in oil sump pickup? B50

It does not stop wet dumping as the pipe exits into fresh air above the oil in the frame, what it does do is keep the oil in the pipe so the return pump starts with an oil supply and does not run dry or lose prime and the feed to the rockers starts immediately.

The backwards curve on the digital is for idle stabilisation, as the revs drop the timing advances and brings the revs back up. You have to remember when tuning the idle mixture that it's there or just use a colourtune.
