The YDS-3 would be a fun bike, just a little difficult to keep the cast iron cylinders from seizing at racing speeds.
I've also heard of the crankshaft-mounted clutch giving problems at high rpm's (TD1's had a similar problem) but the fixes must be known as there are a number of them still being raced.
I don't know if it's "legal", but the 1967 YDS-5 cylinders are aluminum with cast-in sleeves and use the same base gasket, so...?
Probably the YDS-5 is the better choice for P1-250 anyway as it has a more modern engine, with the clutch on the tranny mainshaft, not the crank, plus the aforementioned alloy barrels. You could drive Stan nuts with one LOL.
So far, my saga for a P1 200 bike:
the first BSA 250 I looked at is all rebuilt, pretty nice shape, out of my price range even if the owner was in the mood to sell (he isn't right now),
the '71 BSA is too nice to convert to racing and would make a nice little street bike with a bit of work (has an ownership),
one of the '69 Triumph T25's is way overpriced and needs a rebuild, but has an ownership,
another T25 I found on ebay seems about the right price and condition to convert to a race bike, but is a 1000 miles away LOL,
Aaaaaannnnd... yesterday afternoon I was on the phone with a retired gentleman farmer who has a 175 Kawasaki in his barn. He thinks it's an F7 but is going to check the year of manufacture and get back to me. I rode the bike about 15 years ago but forgot about it 'til recently. He had an ownership for it at one time but "can't find it"... but if he does, the bike will probably go to a friend instead of being modified for road racing. My buddy had one as a kid, bought a KE100 awhile ago to rekindle those old memories but finds that he needs the bigger motor for more oomph (40 years and 50 pounds will do it to you).
Anyway, the search continues...
