This happened on my 441 one night when it was about10-15 out.
I moved the shutter to the winter position and it stopped the chain spinning at idle.
In the summer position in the summer I had no issues

Looking at buying one of these kits.. I am used to OEM and was just wondering if anyone has put an OEM top end in one and had it ported?
How do the cranks hold up?
Looking at a 440,660,or 365
