Adly bullseye engine?

[coachhejl]

Is it a 1e40qmb?

Or something specific to it's adly brand?

I just bought a 2016 bullseye. The only marking on my case says jt-50. I can tell you that I put a cvt cover off a 90cc Adly on it and it bolted right up.
From what I seen, it looks identical to other 1pe40qmb engines.
I'm looking forward to splitting the case so I can see if it will need work to accept a 45mm Airsal stroker crank.

Adlys are weird. They are a 50cc 40qmb but they use a stretched short case style block. As long as you buy for jog or zuma, the parts line up on cylinders.

The reason that the 90 cove fits is because the 50 and 90 use the same block. Opening for the cylinder is just bigger on 90 version everything else is same.


I can tell you from experience be careful with the 45. I'm not sure about airsol itself but I've put a 45 mm crank into one of those cases and I had to Mill the case out a little bit. Rod was hitting the back end of the well. AJ Parts/Adly parts sells Adly 45 crank and bbk thats made for the engine. I have dropped that 45 from Adly in there and haven't had any trouble at all.

Bear in mind that I did this with a jt90 case which is the 90cc version. With a 50cc version you'll most likely have to do some Milling.
