Does anybody know Napa part number for the jackshaft bearing near the speedometers sensor. I'm hearing some bearing noise coming from there and I'm miles from home but there's a Napa down the road from my motel road. It hasn't blown apart yet can I change this in the parking lot with out pulling it all apart. This rx1 is new to me and I love the power.

Also what size Allen key do I need for the bearing lock collar.

i dont think napa has that bearing. its a 6206k if memory is correct. the "k" is for tapered bore. used to only be able to get them from yamaha for over a hundred bucks, but now royal distributing sells a kit with all the jackshaft bearings and seals for about fourty bucks. grab your secondary and try to move it up/down to check the bearing. if its tight then pop the seal and fill with grease. its not really a parking lot job, better to drag it into the room.

I use the NTN ASS205N Bearing. See if they carry that one or can cross reference that part number.
I think the allen is a 2.5mm
Good luck.

the 205 bearing is for the driveshaft, not the jackshaft.

It ended up being the bearing behind the secondary clutch. 150 yards to home and it blew apart. Limp it home will take bearing apart tomorrow. What's the number for this bearing sand can I change it with out taking chain case apart?

Yamaha#93306-20650-00 I would buy oem if it was me,the oem bearing will last a long time,about $35 also they had an upgraded collar to hold the bearing in but if your original collar is in good shape it could be reused ,have heard of people removing that bearing without pulling the chaincase apart but depending on your mechanical skills&tools it would be much easier to to take the case apart&pull &remove shaft assy,there is a write up in the faq section on how to replace

Yup chances are if your bearing blew apart your stuck trying to get outer race out of the frame, I did this with a dremel but be very careful, or somekind of slide hammer would work too

I used a slide hammer on mine. I am just doing this now, came across this thread looking for info. I am putting in a Apex skid and pre studded track.
