Well, Rocket went home today....sniff......
It was inevitable, but still, B-62 is now a bit bummed.
We had another day of jetting today. Crazy what runs the best. I've got two pages of one line notes of the changes we've made.
I was trying to emulate some of you guys here that take astoundingly clear and concise notes - you know who you are. But even my chicken scratch and half-ass attempt came in handy in this jetting scene.
Turns out with the work we did on the engines (Slight opening of the rotary on both ends, and flow the inlet with the carb and box), the 20/20 carb, timing at 18~19 degrees, Pinasco 2-port 177 kit, and the sexy flowed Pinasco crank, the jetting turned out the smoothest at: 160/BE3/116 with 45/140 idle
I tried the 140/BE4/116 (122 bogged slightly at WOT) but couldn't clean up the mid range. I tried a 120AC, 160AC, with the BE4, the BE5, and the 120 & 140 AC, then put in the BE3 and wow, better. Then the 160AC and even better.
And this is all with messing with AF screw between 1 1/2 to 3 1/2 turns out for a variety of pilot jets. I've been dinking with this for weeks, on and off.
The 45/140 works best 2 1/2 turns out but still isn't perfect. I wanna try the 50/160 but don't have one (yet).
I don't understand why the 160/BE3 works better than the 140/BE4, except that it feels more responsive and just "better". I'll put a CHT gauge on next to ensure I don't blow it up, and keep a close eye on the plug, which looks nice so far.
Chris is going to take it easy on Rocket for the next several hundred miles (which should be ridden in the next couple weeks, knowing him), and also install a CHT gauge. He bought me one too, so thanks man!
Oh, and Rocket has a 118 main jet just cause. Oh and both have B7HS plugs.
So it was a momentous day. A momentous day indeed. Both engines rebuilt. Both scooters back on the road. The culmination of many good days, good rides, good stories, good coffee, good friends. And I've got to thank all of you - for all the encouragement, advice, knowledge, skill, and help. It was valuable to us and to these wonderful little machines. Without all of you, this all would probably have turned out very differently (think piles of parts!). Thanks again!
Life is good
Getting ready to ride - cowls off for quick jetting changes
One of the many stops on out of the way places to make changes
Back at the house, eating burritos and BSing on what we've learned. Thanks for getting my thinking straight Mattgyver!
