View attachment 100943 Replaced the 18T chain sprocket with a 32T and went for a spin between rain showers. First is so slow now that I have a hard time keeping it upright. Second isn’t much faster and third is slower than I’d like. Somewhere in between is golden I’m sure but for now it’s manageable for getting the engine running better. Still only have front brakes but at this speed that’s fine.
Harold I never thought wet would ever be a problem in my far western Indian Territory local, yet I confess this winter and spring has been record breaking, drenched, & violently stormy with another 4.5" of moisture predicted in the next 24 hrs. and continued threats of twisters/hail. Yesterday afternoon was however outstanding and I took a relaxed 12 mile cruise in the country before dusk, the legendary "calm before the storm", and I was truly refreshed by it.
Gearing old motors, correctly, typically involves a varied selection of sprockets to work with and time, unless you have the manufacturers data for both motor and transmission, or spend time sorting the ratios of transmission and also accurately determine the engine output shaft speed. I, however, just guess and change cogs till it works to suit. Both my Harley and Simplex have gone through several driveline, primary & final chain transformations and that's 4 sprockets (two for the intermediate reduction gear) to function through the 5 ratios of the transmission. I'm just kinda' happy with both for now...
My main take away: ride in the meantime and polish, or whatever, and people are going to love it and admire your skill. While you bask in the adoration of all! The fruit of your labor has and will continue to pay dividends Harold and none of those mentioned will know you're still tinkering with gearing to get her just right.
Old guys are patient, cunning and resourceful...copy that?
