First, the holy water discussion: my Wombat 94 came with a partial tank of pre-mix fuel, and I've decided to eliminate one variable and mix up fresh fuel since I'm getting ready to finish my tinkering with it and ride. Stock Type 94 engine, freshly rebuilt with new piston and honed cylinder. The engine has 50-100 miles on it, just a few heating-cooling cycles. Break-in will be my task. The PO recommended (and supplied) Blendzall Green (Racing Castor) and both he and Blendzall say to mix 4 oz/gallon, which is 5% or 1:32. I think.
This is puzzling-- Hodaka recommends a mix of 1:16 (6.25%) for "break-in" and 1:20 (5.0%) thereafter, using "2-cycle oil". I imagine that I should follow Blendzall's mix recommendation. But should I "fatten" the oil mix for breakin, as Hodaka suggests?
Hmmm, I see an oddity in the % up there. Ignore that, I'll refigure it later-- mix ratios are easier. And here is where we get to the Holy Water part: is there an oil that is preferable to the Blendzall? I liker castor, from my RC airplane days.
And mufflers: The bike came with a Hodaka spark arrestor insert (#949161) in the box. On the bike (rather in the stock Wombat muffler) was a cut-off end cap to an old spark arrestor (no "guts" of the arrestor), along with an Inner Pipe (#929191A). Yep, the exhaust note was a bit throaty. It's been decades since I've "pulled the baffles" from my motorbikes and my inclination, at least during break-in, is to go stock and quiet on the muffler. Hmmm, this might 'splain why the needle was raised all the way UP to the 5th notch ( I reset the needle to #3, per specs). And it might might be a good idea run that main jet to the shop and see if the jet size is as-marked.
Per usual. comments are appreciated.
