Hi RickyJ/all, my first input on this forum so be gentle with replies and retorts, abuse, etc
(I'm no expert!)
Before turning anything and before 'diving in' with belt change, inspect condition of all pulleys and teeth for corrosion etc and clean, dress as required
as the abrasive action of rust on a new belt will render it to a similar condition to the old one youve just taken off in a matter
of hours.
With the belt off, make up a suitable device with a 17mm socket in a drill and run the auxillary pulley/oil pump for a minute or two ( I dont have dissy assembly on my 2000ie so it spins quite easily)
this will also remove the need to take off cam covers as cams, buckets,bearings etc will all be bathed in oil as they would do while engine
running? then take out plugs and visually inspect to see if top off pistons can be seen without looking through 500cc of coolant?
?
.
If all is well? squirt some thin oil in each pot and as the Beta twinc is canted over at a jaunty angle (20 deg?) try to get it to the top of highest part of the cylinder so it will run down the bore and round the piston etc.
Im unsure about blower unit but I personally would remove carb and try to visually inspect rotors/screws again for surface corrosion?
theres not alot that can be done without a stripdown if there is evidence of owt nasty? but again before 'TURNING' anything I would lube with a suitable liquid,petrol,oil,carb cleaner,? (Iirc arnt the blower 'gears' lubed by an oiler atop the blower casing? can this not be 'primed' somehow too?)
With 'spotless' pulleys and new belt all timed up correctly, plugs out! and the twinc prelubed, it should turn over on the crankpulley nut/bolt quite easily with moderate hand applied torque??? after the recommended 2 full revs of the crank without incident maybe think about turning it over on starter with fuel/spark dissabled to build oil pressure, then and only then, 'pinkies' crossed, 'PLUGS IN'!!!!!! try a normal start?
?
If it does start, dont over rev untill temp gauge has got out of bed!!! then run untill fan cuts in then turn off and try a hot start immeadiatly, then if ok? turn off allow to cool, then before next start, remove a plug or all and check condition of mentioned and look into bores for traces of coolant
2 or 3 more 'warm up' 'cool down' cycles without incident should indicate the need for a road test!?
disc brake condition allowing obv?

If you get her running and then find you cant select any gears while engine running, give me a 'poke' and Ill tell you what I have to do every year when I lay 'Lolly' up and then prep her up for the year ahead.
Hope a small amount of above helps in the very least??? kev b.
