Hydraulic Lifter Problem
At 48K, it's time to spend some $ and go through the cam chest; oil pump, bearings, adjusters, lifters and anything else you see in there that looks even worn. Do it now while it will be apart and save the $ later on.

Pull your exhaust, drop your front floorboard and remove the cam cone cover. remove the cam gears and spacer keeping everything oriented so it goes back together the same way it came off, especially the chain.
Remove the cam support plate and watch for oil pump gearotor and washer to stick from oil on back side of plate. Again keep everything in order and clean is critical. Look at the back side of the cam support palt where the gearotor runs. it is normal to have some marks however galds will allow oil pressure to drop.
Look at the cam the bad lifter was riding on, that lobe should be worn.
Purchase adjustable pushrods, a new lifter, new cams and a cam cover gasket and put it back together. Some would suggest changing all the lifters. Your call.
If it was mine, I would replace all lifters, install a new .555 lift cam and if you dont have it alreadyinstall a tuner.

Regarding replacing the bike instead of repairing what you have...there was a time where we riders were as loyal to what we rode as we were to our friends and family...because your scooter is really a little bit of both. If you like your bike, if it does what you need it to do, why throw it away when it gets a little sick? If you fix it correctly, it will be as good as, if not better, than new! If you are overwhelmed with the task, either soldier thru and learn some new tricks, or just hand the project over to a trusted mechanic. In my opinion, the major portion of the cost of such a project is parts...if you locate an independent mechanic that you trust, and has a reasonable shop rate, when you add in the cost of special tools that you may never use again, you'll probably find that you're better off having the work done by a mechanic.
I've done a lot of engine work in my time, mostly automotive but some motorcycles, and when it's time for me to do what you're doing, I'm taking it to my guy...I'm figgering about four hours at $65.00 per hour...comes with a warranty. No brainer.

If you don't have a manual, now is the time to get one.
I pulled the stock cams, lifters, and the oil pump (I cut the pushrods) back when the bike had 9000K miles. I installed a HP/HV pump, Andrews 57H cam, inner bearings, new lifters, and adj. pushrods. I'm not sure if the stock parts (103ci)would fit, I'd sell them to ya cheap.
Man you re so lucky the wheels didn't totally lock up and the tiny needle bearings get into the motor. Had an EVO do that and within 2K miles the rear cylinder developed a noise. The bits and pieces got between the piston and cylinder, needless to say it required a rebuild.
As for a new scoot; If you are not happy with the old one, fix it cheap and get the new one.
Good luck Bro,

The lifter in our modern twin cams are moving in precision bores in the cases, not like the older twins where we had lifter stools bolted to the case.
Take a good lifter and see if it will slide into the suspect bore(s) and move up and down freely. be sure it is an oiled bore. If it does then move on to replacing the trashed components. If it binds, reply back for ideas....
So you must have the top of the rockers off since you plan to reuse the perfect fit pushrods. Thats ok, you just need a top end gasket set. The complete set for a twin cam is $100 plus or minus and adjustable pushrods the same which is why i cut them out and go adjustable.
If you want to go back stock, check ebay and your local H-D shop, there are plenty of stock cams out there that were removed at the dealership before new delivery.
Maybe $100 for the replacement new/used stock cams, another $150 for the lifters, and $100 for the gasket kit so $350 and you are back in business
