This is probably a stupid question, but I didn't see anything when I searched. Is there a procedure to maintain the bearings on a viper? I don't see a grease fitting or a hole.. I must be missing something obvious.
thanks for any help. Starting to look forward to snow again.

Bearings are sealed at the factory, ...the only way to grease a bearing is to replace it. Should get a few years out of a bearing depending on your riding style.

There are two ways to grease each of those bearings; grease needle or repack.
Purchase a grease injection needle from an Auto Parts store. Remove the speedo drive cover, insert the needle by feel through the very outer edge of the rubber seal on the bearing and as you're gently inserting it, feel it go inbetween the ball bearings. Grease very easily as the end of the needle and the fitting of the gun will seperate if you squeeze to hard. Repeat this in four different spots around the bearing.
Another way to grease it is to remove the rubber seal on the bearing. It's fairly easy to pry it off. Once it's off, inject grease into the bearing and push/work it into the ball bearing with your finger. Replace the seal when your done. Be careful not to bend the seal as it is a thin metal ring sandwiched under the rubber.
Using the needle, you'll be suprised at the amount of water drips that flow out of the bearing after each trip (500 miles or so). Both methods will suffice at keeping your bearings corrosion free.
There's no need to remove the secondary while greasing either bearing, although the airbox must be removed when greasing the jackshaft bearing.
Because I did a track change this year and the bearing was removed, I replaced it at 4400 miles. It still looked new and rotated as new. I've greased these religiously after each trip and always displace moisture when doing so.

I am with ecopter on this. I have regreased (repacked) them many times.

I see bearing as consumables, much like replacing the cartridge in your inkjet printer instead of refilling it. A jackshaft bearing is around $15.00cdn. most other bearings are around $5.00 or less if bought in quantity. I have a 98' SRX with 4,500 klms. on it never had the bearings replaced, ...this summer I'm replacing all the bearings including idlers and I'm noticing all the original bearings seem like new.
I understand your point srx_eh but if the bearing is low mileage and feels and rolls smooth, it will be fine to repack them.
wanna try my buddies venture? 1991 and had origonal brgs till last season with 16000km on sled. im goin after jack shaft brg this year. spedo brg went at 12000km. and i know fror a fact that these where origonal. i still have the scars from pullin the slider set last season and i gotta pull it again this year too. 
and they where never greased.

jack shaft bearing
I replaced mine at 10000 km and it was about time i might of had another year of life left but wasn't taking the chance replaced with bearings from yamaha @ $40.00 each and i'm not going to worry about them for another 10000km

Thanks for the info. I was thinking it would be better to try and maintain the bearings rather than just replace. replacement seems like an involved job. I have a grease needle. So I should be able to do it.
I'm still not clear how to pull seals without disassembly. any pictures on the angle of approach to do this? Or do you have to disassemble everything to grease it. (I hope not)
Thanks

With a greese needle you wouldnt have to pull the bearings but you wouldnt be able to inspect them either. The dust seals are easier to explain when the bearing is out and in hand.
