I know this has been discussed many times and I have poured over discussions, but I am coming up on my 1000 mile service for my 06' XB9SX soon and am trying to decide what type of lubes to use. Should I wait longer before I change to Synthetic? And should I stay away from Synthetic lube with the new 06' tranny? If this question annoys people, let me apologize in advance, but I can't seem to find much 06' XB specific info regarding this issue in the Knowledge Vault. If anyone can refer me to a previous discussion on this matter, that would be great as well. Thanks! | ||

Make the switch... | ||

i did it. i say switch to the better stuff | ||

I just had my 1000 mile service on 06 xb12ss, and I had them switch to synthetic. I personally feel a difference, and it shifts even smoother! Too bad I only got to ride the bike home, because they tightened my primary chain too tight. They picked my bike up today with a trailer to look into it. Hard Corps | ||

Don't let them tell you SYN3 makes more engine noise either.  | ||

Do you all think that using Synthetic in the 06' tranny will be OK? I had read that it may cause some slippage. | ||

Yes, I use AMS oil (MCV) in both holes and I have not had any clutch slippage. The issue of synthetic or not and when is a very personal issue. My opinion is at least 3K of moderate use with conventional and then go synthetic in both holes. I changed my oil (HD-360) at 500, 1000, 2000 and then went to synthetic (AMS oil MCV 20w-50)at 3000. Why did I do this?.....On my ULy the fan comes on most of the time and it is programmed to turn on at 428 F!!!!! That is too hot to cook donuts!!! Also do not over torque the oil plug. The Uly (xb12x) manual suggest 29-34 ft./lbs. It is my opinion that is way too tight. I wouldn't go tighter than 14 ft./lbs.!

Okay, I will laugh. I went into Zooks, here in Des Moines, IA They said we have one guy who can do the TPS reset for you. So I bring it in. I wait an hour. Tech comes out and says, your fan doesn't work, it doesn't come on. I was like what? Are you sure.. I was like t only comes on when it's hot. He said, you must have clipped a wire or disconnected one, I was like I only put in the race ECM. He looks at me funny walks ....away! the service guy then totals it up.. 38 bucks or so.. better than the 75 they quoted me. I get home.. Fan kicks on... Nuff Said.. HAHAHHA.. Harley Dealers vs Buell Owners.. Jerry W Des Moines, IA | ||

I only deal with factory trained guys... With Syn I can hear the valves more now than before but its so small of a sound most people wouldn't hear it.. In the Tranny.... I really didn't notice a difference.. | ||

"On my ULy the fan comes on most of the time and it is programmed to turn on at 428 F!!!!!" I am virtually certain that your information is horribly inaccurate. If I recall correctly, the temp sensor kicks the fan on nearer to the low to mid 300o range. | ||

I only really got to ride it a little bit too after switching to SYN3 for my 1,000 mile service. Well I got the service done at 700 miles since everyone's booked til' June around here but anyways. The fan doesn't turn on much anymore unless I'm out for more then 20 miles. Seems to stay a little cooler since obviously the fan only comes on at a certain temperature so thats proof right there. I had em' switch all the fluids to the SYN3. They're really good with the Buell's out in Utica and he said that you can switch all the fluids out on the first service. And since synthetic is better for an engine anyways and I believe is better if you put it in as early as possible (such as the 1st service) and stick with the same brand so your bike is used to everything on the same level and doesn't void the warranty whatsoever. I'm not sure if it's louder or not, I think since it runs a little smoother I can hear the valves a little more, but not too sure. I still worry about the noise but every single person I talked to said that it's a very noisy engine and when it gets quiet is when you have to worry. Driving wise it's perfect so I doubt anything is wrong, it's just that it's my first Buell so I am still getting used to the fast "tickkkkkk" sound of the primary chain. But it's not like the "shaking a huge can of pennies as hard as you can". And the way to fix it is to get a pipe, heh. That's next on my list! | ||

2000 miles on my xb12s switched to mobil-1 v-twin in both holes and the bike is quiter and shifts alot nicer and fan comes on way less. | ||

Blake, According to the Official 2006 xb12x Ulysses Manual(99494-06Y): Table 4-29 Page 4-80 Key On 220 C (428 F)fan on Key On 180 C (356 F) fan off Key Off 170 C (338 F) fan on Key Off 150 C (302 F) fan off I watched it cycle with the VDSTS hooked up and checked Key off settings and it was right on the money. Then I watched engine temperature approach 400 F Key on and running. The fan did not come on until I turned the key off. My numbers are right. If they were wrong then my dynamic test would not have verified results. Do you have additional data or manual updates? What is your opinion on the key on, fan on temp? | ||

I have decided that for my first service I am going to switch the Tranny oil to Synthetic (probably Amsoil) and go with regular HD oil in the engine. I'm going to wait till about 2000 or so and go all Synthetic. Thanks to everyone for their advice. | ||

The high temperatures got my attention as well but I think there are some circumstances that explain the "warm" settings. The ET is very close to the exhaust valve and the base of the spark plug. I believe this is an intentional move to achieve a much wider engine temperature spectrum. For example the ET sensor on the Delphi FI system for HD has a range of 14 F to 230 F and the VDSTS reads temperatures to 284 F. The Buell-VDO-EFI ET sensor ranges from 14 F to 572 F!!! The VDSTS reads temperatures to 500 F. During fan on / key on situations were the fan kicked on at 428 F the cylinder temperatures were very similar to the HD temperatures of less than 300 F. The "high" temperatures were found only in the high heat areas in the heart of the combustion chamber. I is my opinion that the Buell people felt they could better tune the engine for power and emissions by monitoring and manipulating the EFI by making the ET spectrum much wider and thus higher. Though I admit this is only conjecture and I could be horribly wrong as has been suggested. | ||

Verified tonight that the fan does turn on at 428 F !! When the fan runs the temperature does not fall very quickly even with the help of an external fan. |
