Time for an update. I put on the long bolt logs, jetted the 850 at 78 primary 80 secondary.
The rpm's top out at 5100 to 5250 depending on load and wind.
What total advance are you guys running?
That damm chrome balancer makes it so hard to see the timing marks I'm guessing it's pretty close
28 degrees total now.
I was going to play with that but I've just been taking it easy on the engine for the most part to break it in nice and easy. The GPS showed a best of 61.5 the only day I took it out. I borrowed it from my brother....
I'm happy with the jetting, I do need a slightly heavier secondary spring it has a bit of a flat spot before it takes off.
I'll just finialize the timing advance and be happy with that. I'll be putting on a place diverter this winter and maybe a new impeller. That remains to be seen.
What top end are you guys seeing from something similar to a 23 footer with an A impeller, Berkeley 12JE?
I don't mean with a speedometer,,, I mean with a GPS. My speedo says 64 to 65 MPH when the GPS said 61.5. I'd probably be satisfied if I didn't have use of the GPS
