my wre is not the same as yours for instance u have a power valve controlled by a electric motor mine is centrifugal no motor yours is cagiva mine is bmw very similar but different you should read the list of faults ive had listed in this post all true and very well looked after
when you say centrifugal, all Husky's except the 1987 CR250, yes only one model and one year, very short production run
all others are centrifugal unless you have some info i don't
when Cagiva bought them they used their engines in the 2 strokes
when BMW bought them they left the factory intact and essentially they remained unchanged
save for a few updates and some different plastic the line stayed almost the same
the 250 was updated in 1992 for the purpose of creating a 360 out of the same base
the 250 saw MINOR revisions through it's life (till 2014) with many or most parts being the same or interchangeable
they stopped making the 360 and a few years later added the 300, that was an industry move as most went the same way
the 125 story is quite similar with a very few less parts interchange through it's life
so it's possible you got a dud, i won't say you did not, but most don't, 10 years on my 93 360, oil, tires and plastic parts (due to drops), nothing broke NOTHING
a 99 360, replaced the ignition, replaced the carb for performance, hear the 125's have rod issues sometimes, SOMETIMES
pick any brand and this happens, i have owned more Yammies than anything besides Husky, they break too, but the most reliable Jap ride
if you go to a site where people discuss upgrades and their fun times to bag on a BRAND you are going to get push back
