365 to 372xp??

[Mozza]

Afternoon all, I've got an old 365 that has seen better days and hasnt been running great for abit. I was going to eBay it for spares BUT I've just remembered someone on here saying that the 365 can be re built (quite easily) as a 372xp, performance/power wise.

 

So I'm going to have a tinker with it on day's I'm quiet and see what happens.

 

Just need to know what parts I'll need??

 

Cheers

Apart from the barrell and piston :-)

There is 365 closed port best, 365 open port.

 

372 will bolt right on. 372 comes in 50mm 51.4mm stock oem and 372 52mm aftermarket.

 

Over here they come with 2 different carbs and either will work. Walbro and Zama. Walbros has a little bigger venturi. I ran both on stock and woods ported and I didnt see any difference though.

So if I buy a 372 barrel and piston, it will just fit straight on and work?

 

As long as I buy a 372 carb aswell?

No need to modify the carb etc??

 

365 Max rpm 12500

 

372 Max rpm 13500

 

So even if it was the same carb and basic setting the H jet could be leaned.

 

My 365 Special was so rich when it came it would only reach 11800:thumbdown:

Carb dont matter. Run which ever one you have. Dont just go leaning that H side like posted above, big no no.

 

Tune to 4 stroke a tad WOT and clean up in the cut.

 

The coils if blue are rev limited and have the rpm stamped right on them. Black coil NOT rev-limited.
