not to hijack a thread, but........... Mobil invented synthetic motor oils? Possibly,but for sure they didn't invent it forinternal combustion engines. that distinction would seemto go to Amsoil in 1972, Mobil 1 came out in 1974. In 1969, I remember a guy coming into my dad's garage in northwestPA trying to talk us into test running a synthetic in our customer's vehicles. I don't recall what company that was, but it definitely wasn't Mobil.

not that it matters, who was first. just becauseXX companyinvented it firstdoesn't mean I stayed with or aheadof the competition. who was first is just for advertising hype. discount the hype and always go with real life experience from truly knowledgeablemechanics and technicians.

foxRM250, had the same problem finding the Mobil1 V, found it in the MC section of Advanced Auto, asked the kid at the counter in the store, he did not know they had a MC section so you might have to look for it, I sumbled on it a few weeks later gettingoil for the cage. Try the Mobil 1 V, they invented synthetic motor oil and it is the ony true triple synthetic oil with the right MC specific additive package from aMAJOR oil company, the rest are just blends of one type or another (except smallerMC spefic oil blending companies, cant speak for their quality one way or the other).

Calm down oley55, I did say MAJOR,read a lot of great things about Amsoil, and will probablytry their products in the future, just being safe for now. As far as inventing or not,really have to check the patents and look into the location of their refineries(where lube oil base stockis made, for all lube oils, from specific crudes for syn). Either way, any syn is better than no syn IMHO (which is just that, an opinion).Just relating my experience trying to help foxrm250 with the noise.

I have the 5th gear whine and a small amount of clatter in 6th. Doesn't seem to bad right now, but it hasn't gotten hot here yet. Only have 275 miles on the bike. The noises change with rpms and lower (2000 or less) is worse.

Mobil I Syn Gear oil 75-90W in the tranny is worth doing. I like the idea of a Gear oil in my transmission and finding Neutral is a breeze now.

I took the suggestions from the guys here and I reap the benefit, try it.

If this doesn't work for you, get open mufflers and a radio, that'll fix all the unwanted noise you can come up with.

I talked to a friend who is the service manager at one of the top rated HD service departments in the country. He told me Harley is aware of the problem, and he is hoping they have a fix for the08's. Meaning they might have a fix for our 07's. He also offered the Baker 5th gear fix down the road if HD, doesn't take care of it.
I hope HD gets it fixed. The cost for the baker kit is $1,200 installed. $800.00 if you want to wrench it yourself.

After the Allies bombed the hell out of Germany in WW2 and cut off their oil supply the German's made syntehtic oil and fuel for their vehicles. They produced millions of tons of synthetic oil by 1944 already...I believe in a process using coal. Patton out ran his army and resorted to using German synthetic oil so as not to quit the push to Berlin. Just wanted to clear those 2 things up......

yall need to try REDLINE SHOCKPROOF Heavy(red) or Light(blue) in your tranny...it clings to the gears to cushion the mesh and will quiet it down...IMO, better than the Mobil 1...been a drag racers secret for years...sometimes when ya need to gain acoupla hundreths, we'd drain the diff for the next run(yep, NO fluid in the rearend to cause any drag)...never a prob

no doubt a good quality lube will help quite down a noise issue.
But I still feel the base issue lies with the basic design of the tranny.
Either the angle of cut on the gears is off or the tolerances are too loose.
whine is normally caused by wrong angle of attack of the gears and too close
of tolerance and or preload on case bearings.
But CLUNKING ,CLANGING etc, it something that is too loose.
And no matter how good the oil is, it is NOT going to correct those types
of tolerances and issues
Can't find my machinists book right now it has a lot of this stuff in it.
But here is an online source.
http://www.gearsolutionsonline.com/a...whine0204.html

From a theoretical aspect at the factory everything may seem fine until the
gears get a real world work out and finish lapping in after time, then the problem
starts. It's a cut-throat world out there and everybody is in a hurry to bring something
new and better first to the market. But invariably quality suffers in the end.

I went the other day to look and they had 15/50W but I didn't see 20/50. I know the place where I'll go to get the redline will have the 20/50 there. They are an oil distributor. I have to admit that I have never really tried or been a synthetic oil fan, but as hot as these new ones run, I will have to switch over.
Fox, the 15w50 is fine for your HD. I've seen several tests on oil, by American Iron and Motorcycle Consumer News, that concluded that it is just as good as the 20w50 variant and is about half the price. I've known a number of HD owners who use the 15w50, including a renowned local engine builder.
