Hi Rene,
I could write a long speel about what I did to my HEQ5 to make it work as well as it does but I won’t fill the post suffice to say they are mass made and with a bit of work can be refined. The quick one referring to your alt bolts being stiff. I use engine assembly lube on the thread and on the top of the bolts and they are a dream to use now. Better than I expected to be honest. Give that a go
Cheers
Ryan
