    FYI - Minor clutch slippage on this full synthetic

    Just a FYI - I used this oil rather than my goto Shell Rotella to try out on the TW. It says designed for wet clutches. I had some slippage at higher rpm/speeds today on my ride. I will be draining and replacing, just FYI. I'll either go back to Shell Rotella or just drop in some OEM Yamalube. Keep in mind you results may vary. Just a heads up and something to keep in mind when shopping for oil. Disclosure: I have had good luck with this oil in the distant past and figured I would try it again. The TW specifically however doesn't seem to like it too much. My experience anyhow.

    Here, let me spend some of your money:
    78-17 Yamaha TW200 Barnett Friction Clutch Plate kit -5 Plates (Fits: Yamaha TW200)

    Vesrah Heavy Duty Clutch Spring Set SK-206


    Seriously, nice heads up r.e. the Lucas Motorcycle oil; I would have tried it if I saw it on the shelves.
    The clutch upgrades have gotten good reviews by members here. However you would have to scrape off the old clutch cover gasket, something I wouldn't wish on anyone. Just the stronger springs, or fifty cents for 4 washers under OEM springs might increase engagement forces enough to compensate for the slippery Lucas.

    I put in a new clutch with stiffer springs when I installed my kickstart. Great info and links though. Would have saved me some time when I was looking. Thanks. Also weird to me how watery the Lucas was. Very thin it seemed

    I've never had any slippage in either TW with Mobil 1 4T racing 10w40 after break-in. In total 16,000 miles.

    Make sure you have enough slack in the cable take-up. If it is too tight it can induce slippage.

    I have been running this very oil in my '14 TW since the initial oil change. After 2000+ km, no issues so far... knock on wood!

    I have always used a little Lucas Heavy Duty Oil Stabilizer for slipping clutches. I ran Valvoline 20/50 not for wet clutches oil and many months or years later it slipped so I added the oil stabilizer which made the clutches grab. No more than about 4 ounces and don't go over on the oil level. At 40,000 miles I did finally change the clutch plates out to Barnetts. The steel clutch plates were still in great shape.

    Also, if it grabs too good you may have loosen your clutch adjustment a tad.

    Why did you decide to try something other than the Rotella?
    I use Rotella and haven't noticed any problems at all. Good, solid shifting, engine temps, suspension of contaminants.

    I will be more interested in hearing if the change back or to some other oil corrects the issue. Seems to me once the discs take a glaze or begin slipping there is little you can do other than to replace the discs or sometimes you can deglaze them with fine sandpaper or soaking them in some chemical. I tend to doubt the issue is caused by the oil but rather the change made the already present issue more pronounced. Keep us posted on what you find.
