Don't want to make a ROD for my own back, but all my long lasting cranks had non- slotted RODS, and rubber seals...... ROD!

Hmmm, no slotted rods, no aluminum seals. New rods, used rods?? What rod side clearance? Many questions. |

Aluminum seals don't have the problems rubber ones do, slotted rods and correct rod side clearances help keep the roller bearings cooler, better lubed, longer lived, from all my doings with these cranks over the last 4 + decades. YES, I missed the "New Rods", my bad. |

No worries Dave, I just don't think, (in general terms) we should dismiss rubber seals and solid rods, I mean they do work!

Yes, they do, however, if we can make the situation even better, and possibly avoid issues/problems form occurring sooner, than later with revised parts, I believe we should do that. Slotted rods just work and live better, same for same over unslotted rods, and aluminum seals vs those that can degrade, best to go for the better setups, my opinion. |

Yeah, I am a slotted rod fan, even tho I did a squillion miles on the early cranks! Dave, did the slotted rods come in the same time as the revised (line to float bowl) oiling system, or was that un-related..?? Aluminium seals are nice too, just not sure on the availability of them currently, maybe the crank guys have access..??

On the proddy bikes, yes, about the same time, because the later 4 outlet oil pumps literally made the oiling system a premix one, by dumping the oil into the fuel in the bowls. Yes, the left main/rod system was still there, but it never did contribute much to the oiling system. What some just don't see is that the bottom of the cylinder end banjo bolt has one restriction, for the main/rod, and the cylinder has the other restriction for the inlet port, on the 3 line systems. The 4 line systems had different metering into the float bowls for the premix addition to that system. Many have simply drilled and tapped a side boss that dumps the oil into the slide area of bigger carbs, but the correct way to have done it is to use the stand pipe and bowl boss, like the stocker carbs had. Sure, the argument can be made that the oil line into the idle screw boss works just fine, but, that does not make the system work as the correct premix system it was designed to be. Although I like the 3 line systems best, the 4 line premix systems do work better when the oil is added to the fuel in the bowl. The slotted rods helped get that premix into the big end bearings a lot better than the non-slotted ones did. If one has seen both H1R and H2R rods, they are slotted, always were, even when the proddy rods weren't, because they worked a lot better with the simple 3 lines to the lower end, premix in the bowls oiling systems used on the race engines. Every H2R crank we ever used, had the oil receivers in place from the factory, and we never saw any reason to leave them off, especially the myth that they added significant drag to the cranks, they just plain never did. Me, if it is a two stroke, or even a centrifugal spin lower end 4 steroke like the Z1 and KZ900/1000/1100 engines, slotted rods are just the way to go. |
