Some good advice here on transfer port matching to the sleeve. I think for now I will tread carefully by doing nothing except putting it back together now that I've repaired the broken head bolt. Never had this '94 61X running or in the water so itching to see what it's like compared to my '14...
yeah Bar jumper those look about as nasty as my "6 6" (or "9 9") 61X cylinders. Maybe the rumour that the "0 0" stamp is the best sleeve-cylinder port match is a myth. Or maybe the quality control guy with the stamp was dozing on the job. Anybody else got numbers/pics? I think TheBuzzard is...
barjumper you may be onto something... these numbers are "stamped" rather than "cast" into the cylinder alloy so are likely applied during assembly. Maybe they are an indicator of which sleeve went into the casting while the cast-in numbers indicate which alloy cylinder cast was used. This...
eastcoastjumper what numbers do you have above your exhaust ports and elsewhere? I have similar sleeve-to-cylinder misalignment on the intake transfer ports and my numbers are 6 6 or 9 9. Here's a pic of the three middle intake ports on mine, and the most drastically misaligned. The 2 intake...
Yes interesting... mine has a 6 6 or 9 9 on the top of one exhaust port (depends which way you read it) and no numbers on the other. I also have "Y-1" stamped on the unit below the exhaust ports. The other side has "61X" and "3 X 1" or "3 1 X" on it as shown.
Anyone have some different...
I think so eastcoastjumper; looks just like mine. kevbo may have gotten it right too when saying that the cylinder casting port timing/locations are different than the sleeves on some of these units, perhaps only on the intake transfers as the exhaust is aligned very well on my '94 61X and on...
I've opened up a '94 701 to find similar misalignment of sleeve ports to cylinder casting. Freakrider you said the cylinder casting determines port timing but that doesn't make sense to me as the port is opened/closed as the rings/pistons pass the edge of the sleeve port, not the cylinder...
Matty you were interested in a Blaster... I'm in Mission BC and have a red '95 Blaster 1 with Factory B pipe, Thunder Cats high compression girdled head (180psi per jug), aftermarket flame arrester, Jet Dynamics scoop grate, Ocean Pro ride plate and stainless impeller. Awesome thrust. 61x 701cc...
