Last post by Simoniz - February 16, 2026, 08:40:55 PMBelRay Gear Saver 80W has given me the best results out of all the various oils I have used over the years. Better shifts and smoother all round.

Last post by SoCal250 - February 16, 2026, 06:30:42 PMThe oil nozzles on the carb bodies are no longer available, however Economy Cycle sells reproductions.
The hose for pump to carbs is still available from Yamaha. In my previous reply I gave you the part number. One pack is enough to do both sides. Economy Cycle carries that as well.
The hose clips used at both ends of the distribution hoses from the pump are also available from Economy.
The supply hose from tank to pump (90445-09122-00) is also still available, and if I remember right it's about 700mm (27.5") long so depending where you mount your oil tank it may work.
EDIT: just measured a new one from my inventory to be certain on length and my earlier statement was about right, and it's closer to 27.7"

Last post by Tropic-al - February 16, 2026, 05:45:21 PMIn my cars I use Mobil1 Synthetic.
on the 2 Yamahas, a 1979 XS1100 F and a 2015 VStar 950 Tourer, I use Yamalube. If not for the only reason that if they warranty their new bikes for 3 years, their oil must be good enough.

Turning Wrenches / Re: All Balls Steering Needle ...
Last post by 2 Smoker - February 16, 2026, 05:03:22 PMQuote from: SoCal250 on February 13, 2026, 08:00:27 PMQuote from: 2 Smoker on February 13, 2026, 07:24:36 PMI am going with the sealed ball bearing setup from Economy Cycle instead of the all balls needle set up.Since you've already got the tapered bearing races installed, why not run the tapered on the bottom and the caged type on the top? The lower is the one that carries the load and that's where tapered bearings perform better.
Unfortunately while tapping them out the needle bearings were kinda not going to function as designed and they were tossed into the garbage can.

Last post by Tropic-al - February 16, 2026, 04:42:59 PMThank you SoCal for your concern and advise, it's well taken.
Like m says, since I mounted the RD400 motor on a FZ600 frame, I still have to find an oil reservoir and a mounting place for it. Have a few ideas. Before I spend $ on anything else I would like to see the motor start, run and shift as it should. Somebody else rebuilt it and has never been started. Hence the premix as a first step. Hopefully everything will go well and then I'll hook up the pump.
Another thing i noticed is the fittings where the oil feed hoses (circled in red in SoCals picture) attach to the carbs are crushed. Can I get those with the lines from pump to carbs from a vendor?
Hopefully I can get someone to help with posting some pictures. It would be a lot easier to explain my needs and work done. Thanks again to all for your input.
