I've been using the Rotella Syn for a couple years now and have no issues with it. My slippage started well before the introduction of the Rotella but the symptoms were the same as yours. You should be fine after the Barnett's springs.
Yeh but what oil were ya running before the rotella that may have also had not alway wet clutch freidnly fric mods or less zddp that not FT cam friendly either which is the more important of the 2 issues?
Anyway,if your running rotella T6 5-40 it still has just enough zddp/1200ppm whats considered minimum protection for a stock mild FT cam application vs for example rotella T 15-40 that has slightly less then 1200ppm zddp.
You seem to know bikes pretty well and wonder why for a few $$ more why you wont simply run oil that's specifically mfg'd with proper additive pkg designed for an old school air cooled FT cam'd motorcyle motor like the RS has.
I am sure some of the 6-7 or so FT cam/lifter failures we have seen here in RSC over the ast yr or were caused by running improper pass car or truck oil with too low zddp lvl.thats for sure.
That was a real issue with FT cam'd classic car motors untill people got on board with the changes in the oil industry and it can affect the Ft cam/lifters in the RS the same way too!
I just dont undertstand or see any sence when so many guys here in RSC that really like thier bikes caring well for them then on the other hand refusing to spend a measly $10-12 more to buy proper motorcycle oil ?
With motorcyle oils like Amsoil mcv or mobil-1 v-twin both full syn in 20-50 with a much better 1400-1700ppm zddp lvl for significantly better protection of the FT cam & lifters in the RS motor & better protection from the extreem heat generated by the lrg old school air cooled RS motor too along with no fric mod that arent always wet clutch friendly either?
Just makes no sence to me to forgo/give up all that additional protection the Asmoil or Mobil-1 bike oils provide for no reason other then to save $10-12 per oil change on 4qts of oil to purposely run pass car/truck oil that of course protects ok th at we know wont gernade the RS motor but it's defiantely not the best choice protection for the RS motor either.
I understand what you are saying, My last 3 changes have been MC oil after reading your comments over and over again, got me brainwashed. LOL Other than that, I used Mobil 1 syn for over 100k and nary a problem.
But lets look at the big picture, I gather that Yamaha makes approx 7500 roadies a yr. Reason I say this number is due to the number of bikes listed on the recall on gov't site which was 29,xxx bikes, so for 4yrs that approx 7500 a yr being made. So even if using that number and even if there were 10 failures due to oil, it is way less then even 1% failure. And this is the same reason why I say that there are no common problems with the Roadie. Just about any "common problem" is less than 1% when you look at the big picture. To me, a "common problem would have to be in at least 5% to 10%, and none of these issues have come even close to reaching such epidemic proportions. It's also one of the reasons a lot of dealers have not heard of some of these issues. we see a few hundred people on here daily, a dealer might only see a handful of bikes in the entire yr.
Well the M1 oil you were running is misleading because when i was chatting oil with you told me you used to mobil-1 15-50 race syn oil that i checked on and per mobil website which showed it has 1300ppm zddp which is not your std m-1 pass car oil with only 900pm zddp on avg with a couple grades in 1000-1100ppm range.
The m-1 15-50 race oil you told me you were running with that 1300ppm zddp protected the ft cam/lifters just fine while std pass car m-1 wouldnt do as well with ft cams.
M1 site even states thier 15-50 race syn oil is speficically designed for FT cam applications ,only issues these could be with fric mods the m1 tech told me that oil has in it and rec not to use it but i know it didnt cause any clutch issue for you.
OK,i see where your comming from but with all that said theres still no good reason to not run correct oil with roper additive pkg for any application its being used in weather it be a bike/car/diesel truck/mower etc because no matter how you look at it theres not a big diff in cost when you run right oil for application.
But if there was some way to tap into and or get reapir/srv'c data from yami
on the R* i bet there would be more FT failures then you would expect along with other issue that come up as common with the R* too.
We only have a small population to get data from here in rsc and there are a some common issues that come up in this samll comunity like loose pulley nut/i see plenty of starter relays going bad (my 06's went bad at 5k miles!)carb
puke,wack clutch spring,weak rear shock spring,weak front fork springs,undersized cables from battery to starter,intake leaks talking on stock untouched motors,elec f-pumps that take a dump at all diff mileages w-some lasting 35-40k miles and some die at 8-10k miles,fuel gauge sending unit (could be an ethenol issue reducing its srv'c but dont know for sure on that),etc.
I repsectfully disagree because we are seeing these things happening time after time here in rsc's small population vs the 1000,000K's R*'s sold accross the world we dont know the true reliability/srv'c issues that are documented at the dealer where i'd suspect we would see a lot more of the R*'s srv'c issues i listed here.
But as with something like we are talking about here we will never know if you or myself are even close to being on target or not with the R*'s srv'c issues as an overall group so its an educated guess at best on my part.
But it make for some good brainstorming at times not that i need to work this old brain any harder then i have to these days!!!/LOL!!!
Have a good one!
