I want to change my 350 std stock alternator.Which alternator are best for my bike SPARX High output 219 watt three phase alternator or wassell single phase 200 watt alternator.Please give some advice if anyone fitted high output alternator.

Not sure about output requirements but for ease of fitting the Sparx unit is the first one I have ever fitted that went on without a lot of messing about to get a decent air gap. I had to fit one last year just outside Dijon when my original one was fried when the oil in the primary chaincase decided to vapourise and explode. Here hopefully is a pick of the remains.

Has your old one packed a sad or are you after running some major lighting? Otherwise it's hard to see why you'd bother. The major issue I had with the old six volt set up on my Bullet was that the voltage regulation method was so primitive. A Pazon Reg/rec and everything works perfectly. With regard to setting up the air gap I found that setting the whole thing up with the stator retaining nuts just pinched up but not tight and then a gentle tap with a soft hammer got everything in the right place in a trice. I spun the engine over with spark plug removed in order to check that there was no interference at any point and then tightened the whole shebang up tight.
