Final Drive Lube?

[Stu64]

I wonder what ratio's some of the cruisers have? The microfisch shows what looks to be the same style rear ends. They have a V-Star venture 1600.

Hum :mellow: .... rear end swap, just what I need.... er, my bike needs. I seldom use first gear anyway (no PTO here), so a lower ratio won't hurt the take off, and will help on gas consumption. I assume it will also take down the GVWR.

Now, what gear oil shoud I use after the pumpkin swap? :wacko:

Windjammer, hate to burst your bubble but the Venture is still around. Now called the Royal Star Venture, still uses the same V4 motor and drivetrain. The look is slightly different than the 1st Gens of 1983-1993. Has been in production again since 1999.

The difference in the differentials is 11 teeth on the pinion in the FJR/VMax and 10 in Venture. Both has 33 tooth ring gears.

After my first comment last night, I went back and checked the book. If I'm looking at the right numbers, FJR is 33 tooth ring and 9 tooth pinion or 33/9= 3.66:1. With a 11 tooth pinion....33/11= 3.00:1 :wacko:

Without counting teeth....I would bet the Venture is the 33/10 combo as MNFJR05 says, but FJR has a 9 tooth pinion....Forgive me, I'm and engineer and h34r: numbers all day long. Still $600 isn't bad for a pumpkin, find a wrecked one for $300 and I'm in....

A "little" more than a chain and sprockets. I think it cost me about $150 bucks or less for two new Afam sprockets and a DID EV series chain for my Ducati. Oh...and I bought a nice $80 chain tool, but I don't have to buy that again.

 

[PapaUtah]

Escape, you are correct. Brain spasm on my part. Venture is 10 tooth, FJR/VMax 9.

Who knows whether you should useMobile 1 Synthetic 75W-90 or 75w-140? Both of those meet the GL-5 spec. I can't find anything in the Yamaha docs that says anything other than GL-5. Even the bottle of the Yamaha magic juice doesn't say. How can I be sure? Oh, Valvoline also has a synthetic 75w-90 gear oil. Maybe I'll use that so the brakes and the pumpkin will have the same brand in them.

CHeers,

Jim

For what it's worth, I use Mobil 1 75-90 and have had no problems in "only" 1300 miles of driving.

But.......there are others out there with thousand of miles on their bikes using 75-90 mobil 1, not to mention a bunch of V-MAX owners too.

sorry to continue the hi-jack, but the Venture rear intriques me. I feel like the FJR needs a 6th, and I'd be willing to give up a little grunt for lower revs. How can I find what years are swappable, and do I also need to change anything on the FJR wheel, or is this really as simple as swapping pumpkins?

I had a great experience with one of my old Hondas where I swapped a 3.18 rear in my V65 Sabre for a 3.40 rear out of a Nighthawk S. This would be the opposite, and serve a new need. I always find it nead to modify a bike with the same parts-bin approach that the company used to bring it to market

Thanks in advance for some help/info!

Don't say sorry, just don't do it. Start a new topic. It serves the forum better because people will know what the topic is about and go to it when they want. :huh:

I don't agree that the Royal Star Venture is a continuation of the Venture. Pre-93 was a touring bike like a Goldwing, & the RSV is more of a cruiser style bike. The Venture was a primary model name, but Venture is only a sub-name of the Royal Star model. Same motor and drivetrain? OK, but I'd call that "parts-bin engineering", not a model re-introduction.

I'm with you bro, I was bein' sarcastic about the "little more" part, guess I didn't really make that clear. You wouldn't catch me payin' 600 clams for a pumpkin either! Not unless mine broke, that is, but that'll never happen after all the wonderful advice I read here about synthetic gear lube!
