But can I use their gear oil in the primary. Is the gear oil for auto applications different than motorcycle applications? I want to do what is best for my bike, without having to drive 100 miles to get a product.
So here:
Engine oil ???
Primary ???
Tranny ???

Thanks,
Gary

1st --- watch the grammer here. 2nd -- can't you have Spectro shipped to you?

Hello all - figure I would use my first post on something important because, well to be honest, when in doubt ask.

I have a 2009 Nightster - no mods. I have read thru the posts and can not find a straight answer. With the Primary and the Trans using same oil - can I use Redline V-Twin Trans oil w shock proof? I drove all over town looking for spectro hd primary as suggested for sportsters but no one around carries. The local Cycle shop sold me a qt of this stating that it is a solid substitue. Issue is that the posts I have found here do not state that clearly

.

So can I use this without issue?

Thank you all for a great site - hope to be adding value soon.

The redline shockproof is a very good oil but I think I would hesitate to use it in the sporty with the shared oil cavities. The viscosity index of the redline could cause a dragging in the clutch plates and it is known for it's outstanding clinging ability so I would find another oil to use myself.
The chain case oil from spectro as posted in the first post is ideal for the sporty chaincase/trans if you can find it. I believe someone stated you can order it direct from them and there are other links as well to order it from, It may be worth the wait rather than cause a dragging problem in the clutch plates with the thicker oil which would cause a problem shifting and finding neutral.

Glider, I followed this whole discussion and found the local Spectro dealers, problem is they did not carry the 75/140 I did find Spectro 80-90 hyphoid motorcycle gear oil that is GL-5 I know it wont have the viscosity for start up but will it work for my wifes 07 streetglide tranny?

By the way been reading you guys here for a year and decieded to join, very good info and thanks for taking the time to answer questions like this!!

It;s better than engine oil in any case. I would prefer the 75/140 thou.

If they are a Spectro dealer they can order it in and have it in 1-2 bus. days.
When I first started buying from North End Cycle they didn't carry it either.

I've talked to them and all say they would have to order a min of a case and they don't want too because I'm the only one so far asking for it.

I can order it off the internet but thought I would try supporting the local establishments first.

Thanks for the info!

i see about the spectro 6 speed oil superior. but what about the oil and primary?? is it better than mobil 1?
i dont want to track down diffrent products

Formula+ is good in the primary. No energy conserving oils in there and preferrably not synthetics either unless it specifies for use in the primary.

so it sounds like the best thing for my sportster is heavy duty spectro primary in the trans and then the mobile 1 v-t 20-50 in the engine?
