The 545 is in too. I wonder if the difference in the detuned 545 to the 550 is just the transfer covers like 555 to 562.

Maybe rev boost difference too.

545 is replacing 353.  I like the looks of the all orange on the 545 and 555 best. JMO.

550 bore and stroke  per husky website

43 mm / 1.69 inch    
34.5 mm / 1.36 inch


346 NE per husky website

44 mm / 1.73 inch   
32.5 mm / 1.28 inch

The 346 NE has a 44.3 mm bore, to get right over 50cc (EPA related).

We know  .

Thats why I said per huskys website.  We wont know the true bore of the 550 till someone is inside one and measures it.

got my new 550 today, I like how it feels but will run her stock for abit before taking her apart , I want her fully broken in to get a true time  before porting it , I want at least 20 tanks threw it first

I have already seen the inside of a 550 , Once I get some more time on this 550 I can make a better carb statement but so far I wished the 562 came with a walboro instead of a zama
