I think Hetrick racing would argue a lot of parts are indeed interchangeable.</end quote></div>
Well most of the stock engine/trans parts will interchange(as they will with most of this style CVT type atv's) but they are not the same..Like I said different bore size,different carb,different exhaust, roller wieghts electrical system,chain size, etc and the chassis is totally different.It would be very difficult to name many parts that are "identical"....As far as "aftermarket" bolt on parts for the engine yes they may well be the same regardless of what was original equipment on the atv...
For example the Eton has an 82cc engine with a smaller bore than most(50mm VS 52mm)..If your buying a rebuild kit from Hetricks they will likely just give you the more common 52mm top end kit which will take you out to 89ccs...It's not the original parts but it will give you a little more power which is what most people are after.
