90226 20W50 Powersport Motor Oil V-Twin - 1 Powerpack Kit

Great product

This is by far the best line of oil products for big touring bikes. I have a Harley-Davidson 2008 Road King FLHRSE4 and the transmission quieted down noticeably and the shifting became smooth as glass. No more clunking and hard shifts. The primary case got quieter as well. The engine runs much smoother and about 10 degrees cooler. I also noticed a performance enhancement at the throttle after using the fuel additive as this cleans up the injectors. This is a great kit for doing seasonal service, and I am sold on these products. Much better than Amsoil and well worth the price. The funnel is handy, the hat a cool give away for a door prize at biker events, and my grandkids are into the stickers. I will continue to use RED LINE PRODUCTS as they are DA BOMB!

I only use Red Line Oils for my 2025 road glide. Buttery smooth, and I’ve noticed the motor run a few degrees cooler compared to SYN3.

This is just a great kit for doing a 2500 mile fluids change on a Harley V-Twin. Everything you need except the wrenches and a receptacle for the used oil. Took about an hour, I had fun and saved a load of money vs. having it done at the dealership and I know it's done right. I am also impressed with the quality of the oils provided. The transmission shifts more smoothly... just snicks into gear now. The little extras like the funnel are really handy too, even though I already had funnels. All in all, this is a great way to get on the road to doing your own periodic maintenance on your Harley. Next time, I will just buy the fluids but will definitely get them from Redline.

Love this oil. The big thing I really like on an older bike is that each of the 3 oils looks different so you know what is leaking. For example, if you've had a shift shaft seal leak (and who hasn't on an older harley) you know the transmission fluid leak drips down the hidden back side of the inner primary. This makes it look like your outer primary gasket is leaking primary oil. The red line tranny oil is thick and bright pink so you can immediately tell that it is not the primary that is leaking. Have fun getting to and replacing that $5 shift shaft seal though! The red line tranny oil also makes the transmission significantly quieter than just using Harley SYN3 in it. No huge clunks and you can monitor your tranny oil level (if you happen to have a leak) by how easy it is to find neutral. If it starts to get real finicky, you are low on tranny oil. I don't put a lot of miles on my 2004 Harley-Davidson FLHTCUI Ultra Classic, but have been riding occasionally to work when it doesn't rain. Probably shouldn't do this, but I run this oil for two years straight between changes. Motor is an 88 bored to 95 with a bunch of screaming eagle high output parts and cam that the first owner did 15 years ago. Runs well in stop and go traffic in the southern heat, as well as, the moderate winters. No metal shavings and oil flowed smooth during the recent oil change of the 2 year old oil.

Premium oil for Harley products, need to buy an additional quart of primary oil for m8 powered stuff however. Harley spec for the m8 bikes is standing upright (on a frame stand or someone holding the bike), the level should meet the bottom of the clutch spring retainer plate when filled to the correct level. See pictures for spec diagram and how far one quart gets you.

Red Line trans fluid is the best there is. Makes getting into neutral so much easier, I won't use anything else.

Perfect kit for a 3 hole oil change for my twin cam Harley Freewheeler.

Speedy service and great product

Very good kit for Harley oil change. You need to buy an extra quart of primary case oil if you are doing the big touring bikes since they take more than a quart in the primary. The funnel is an added bonus and works great!

Delivered before the approximate time of arrival...thank you!

Really like this oil and best price and shipped to my door thanks again.
