@Precious, here ya go.

Measure the banjo bolt diameter, then measure the OD of the boss the washer sits on and you will have your size. I did look up the part and sizes are not given because Yamaha wants you to buy their stuff rather then provide useful information. You could always buy the assorted sizes for $10.00 versus the $5.37 Yamaha wants for each washer and have a lifetime supply. https://www.amazon.com/LordHardware-200pcs-Sealing-Washers-Assortment/dp/B08SHYWDFK/ref=asc_df_B08SHYWDFK/?tag=hyprod-20&linkCode=df0&hvadid=693270340278&hvpos=&hvnetw=g&hvrand=9307670490974978852&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1026758&hvtargid=pla-1416628693137&psc=1&mcid=dbba1e24d90e305aa71412027c632def

Still waiting to hear from @etcswjoe, but @N3FOL, FWIW the 6607 is a better filter than the 6017A and costs $2.00 less.

Same size and qualities of OEM filter. https://www.fram.com/fram-ultra-synthetic-oil-filter-spin-on-xg6607

Fram XG6607 car filter from Walmart $8.97. Can pick up oil/filter, Cheetos and new underwear all in same location.

@VentureFar, I have enjoyed using these. Click Here for Wadsworth Tools. 20240912_205324.mp4

Yamaha is lying to you. Shinko has all sizes. click the links below to see all sizes. Shinko 777 and Shinko 999 be sure to scroll down to see all sizes.

@Doublehorse Rider, I'm still liking the Shinko's. I have not worn out my 777HD's yet to try the 999. But when I do that is what I will get.

Well... your choices are fit OE or aftermarket wheels/tires or just put some 17's on it (which are very easy to find )

An '01 Yamaha Royal Star Boulevard with 17" wheels? I can't find such an animal. Don't say it doesn't exist, I just cant find it.

Is this your bike? https://www.autoevolution.com/moto/yamaha-royal-star-boulevard-1999.html#aeng_yamaha-royal-star-tour-deluxe-3000-1294

Sometimes it happens but not by choice. You can run a rear on the front, just remount the tire on the rim so that the direction arrow is backwards to the direction the tire is actually turning. Or, since you have to remount the tire anyway, get a new Front tire, mount it correctly, and save the old one for use on the rear.

Out bikes will never have a contact patch problem at maximum sidewall pressure as they mash the pavement down so hard. 🤣

This sticker should be on your bike. Also, this info is in your owners manual. If you dont have an owners manual, you can get a PDF for free from Yamaha website, or right here on this site. For me, I run a 130 size front tire and keep both tires to maximum sidewall pressure at all times.

Shadetree Surgeon bemoans the loss of The Royal Star Venture V-4 at 13:22 in this video. He is not real happy with the V2 version of the "New" Venture.

Your dealer can get them direct from K & L Supply, or you can get them from Amazon. The K & L Supply points are quality Japanese made points. https://www.amazon.com/Supply-Universal-Point-Switch-18-4615/dp/B0034ZMVKU

Get ahold of your factory fuel pump and replace the points in it. Check vent line from top of tank all the way down to the check valve all the way down to the bottom of the bike for blockage.

@BratmanXj try https://dealer.klsupply.com/carb-fuel/carb-fuel-products.asp

A good sense of humor tho.

Does it die because it has no electrical power? Check all wiring and grounds by wiggling them to see i connections are loose. Possibly an add-on ignition relay problem like mine was. Click Here To See Ignition Relay Problem & Repair Does it die because it runs out of fuel? Fuel Pump after your 10 minute time period, should be clicking upon restart. If not, check fuel pump points.

Check the fuel pump points.

If you are sure that you really have put in 5.6 qts total in (count your empty bottles etc), run the engine for 5 minutes and recheck level. The hard way is to drain oil, measure what came out an start over.

I would contact the seller on Ebay.
