Performance question

It has been said that you can go from dino oil to synthetic oil and back. But don't make a habit of changin too many times or you can gum up yer clutchs and have a mess on yer hands. It can effect yer seals too from what I understand.
Synthetic oil should cut down on some heat, lubricate better and cut down on engine wear.

Good shot cardboard. I'm planning on switching to synthetics and hopefully never going back. Redline's not easily found in a store here. I may have to order on line, ugh.

I'm thinking of doing just that this Friday. I called at least 6 or 7 stores listed on Redline's website and only one carried their products, and that dealer didn't have the Schockproof gear oil. I may go there for the motor oil anyway, even though it's an hour both ways, considerring traffic and a bridge crossing. I'll check on New Jersey locations, that might be a nicer ride than ffrom Manhatten to Queens.

have any of you heard of amsoil synthetic, good or bad? harley-performance.com sure talks highly of it.

NASCAR fan yes. Know where you live, yes. My house is approximately 3 miles south of the N. Caroliina border and approx. 15 miles east of Tennessee. Come to the mountains. There's no riding like it anywhere else. hills, valleys, very little traffic and lots of curves. It's a blast. Good luck with your new ride. I use to own a Harley Electra Glide and sold it. Bought:roflmao: a rice burner and tried it on for size. What you hear is true! Once you've has a Harley nothing else will do.

I've been a Amsoil dealer for about 6-7 yrs. Don't push it much.
I use it in my bike when I order it. Use MCV 20w50w in the engine and primary. Use the SVO 75w-140w in the transmission. Amsoil is very, good oil. I like the K&N short Chrome Spin on Oil Filter. Its a high micron oil filter. Uses a 11/16 socket to take on and off and has a pressure releaf valve. No fighting to put it on or off.

K&N Long Chrome Oil Filter, for 1999-2009 Twin Cam® J&P Cycles®

If you don't have time to git AMSoil go to Walley World and git some Mobile 1 20w50w V-Twin Oil . I do not like their cheap oil filters. They git in the way of the crankshaft sensor and correct me if'n i'm wrong they don't have a check valve and have paper in them.

Thanks again guys. I've heard nothing but good things about Amsoil, and the indy shop where I'm going to do my dino to syn change uses it as their go to synthetic. If it turns out to be too much hassle, I'll just use Amsoil, but I'm curious about the Redline products and will probably try them first. HRK, thanks for the links bro, I'll check it out.

Yeah, the tolls are ridiculous here. To see my friend in Staten Island (5 miles away and part of NYC),
it costs $20 in tolls.

Just to be sure, these Redline numbers are the best weights for my 07 Street Bob?
20w. 50 motor oil
Shockproof Gear oil (V Twin)
V-Twin primary case oil 75 w 140 NS

Various websites seem to point to a different weight for the primary case oil.

Thanks for the feedback guys. I think I'm giong to order the amsoil and do a complete fluid change. Looking at the weather forecast for love country, it doesn't look like i will be doing much riding for the next week or so anyway. Just heard a bike go by on the interstate (64), im jealous.

let us know how it turns out Possum

Cardboard; Dont know about going back & forth over and over again. Wouldn't think that would be good.
ON my 07 I broke in on dino, then switched to syn3 in all 3 from 1-10 k then my dealership said MOCO is recommending staying with syn3 in motor and using forumal+ in tranny and primary. So for the last 7k I have used that combo and I am pleased with the results

I'm om my 3rd motorcycle in 3 yrs. Got 23,000 on the 08 FLHT. I've used 20-50 in the motor on all of them in the motor and primary. I got a buddy that we tried the SVO 75-90 heavy duty gear oil in his transmission that was making some noise. Most dealers carry this. When he seen me changing my transmission oil to the Amsoil SVO 75-140 which is more expensive he wanted to try it.
We stuck it in his bike and he said the noise nearly disappeared.
I know the 75-140 is heavier than the shockproof oil.
Transmission shifts good with it. These new bikes run good but make more noise than some of the older bikes. They don't vibrate as much oh.

I just changed my oil again and used Mobile 1 20w50 in the motor and primary and the K&N oil filter.

It doesn't matter that you have to git the very, very, very best oil that you think is made.

Its that you find where you can git a good synthetic motorcycle oil and a good oil filter and change yer oil like every 3000 miles. I like the K&N cause of its ease to put on and take off and the high micron filter. Amsoil and a lot of other filters do not have the nut on the end. And the CPS gits in the way so does the oxygen sensor. Replace one of these by gittin a filter wrench hung on it and you will see what I'm talking about.:gah:
I change my primary about every other oil change and the transmission a little longer than that.
The transmission oil comes out cleaner and don't have any clutchs or pad material in it either.:rant:

I've heard about the formula plus be used in the primary.
But if'n I'm using synthetic oil, why do I want to mix it with formula plus that ain't the same kind of oil and break down the systhetic oil
If yer using dino oil and you want to use it than use it.

Amsoil was used in some race bikes and they claimed they got as much as 10 hp just by puttin it in.

Got buddy's riding 99 model Ultra Classics and they don't even put formula plus in the primary. Non or us has had a problem.

Sorry to be asking the same thing once again. Art NJr, one of the more experienced bike talk members had recommended Redline's 75/90NS primary oil and here the consensus has been 75W/140NS. I live in NYC. Gets hot in summer and cold in winter, but not Alaskan cold, if you know what I mean. Some stores carry the 75W/90NS but not the 140NS, that's why I'm double checking here.

oops, I wrote to Art Njr and he recommended the Plain 75W90 for the primary, with the "friction modifiers" ( quoting Redline's site) NOT the one with the "NS". I'm good with the gear oil and motor oil, just trying to get down to the last thing.. the primary, and I'm still a little confused. Forgive me, when it comes to this type of thing, perhaps I'm like the 140, a little "thick",

I'd appreciate help in clarifying, anyone?
