New Moto Guzzi Door Mats Available Now
I think Tecumseh has been gone for a few years now. I seem to remember they went broke trying to compete on price with the Chinese small engine manufacturers (which Honda, B&S, and Kohler really don't try to do). IIRC Ridley motorcycles did use an adapted B&S Vanguard V-twin.
Don't think anyone mentioned GPX yet, https://gpxmoto.com/index.php?route=product/category&path=5 They have a good selection of 4 stroke or 2 stroke, air cooled or water cooled, smaller wheels vs. normal sized wheels, etc. Each time I've looked into bikes like this I end up with the best idea is a nice used Japanese bike. I start off looking at ~$1200 Amazon bikes. Mostly a bunch of crap parts, poorly designed, poorly assembled, so would require a lot of work to sort out and keep running well. Then look at the Hawk at around $1500, which is a wee bit better than the $1000-$1200 bikes, but again, lots of low quality/design parts thrown together.Then next thoughts go to the CSC TT250 at around $2300. US importer, stands behind their products, a bit more picky about all the parts and how they work together, very responsive with parts and upgrades. So with this one it is more likely to work OK from the start, and just some cheap stuff to deal with as you go (like pathetic quality chain). So a bike you can buy ride and it will need work/attention at about the level as a ~20 year old Japanese bike. But as for fun riding, hum, not that great.So then up to GPX, the XTR T4 250 LC 21x18 is $3100, US importer with parts/support, finally a bike that actually works and is fun to ride. But wait a minute, now you are at $3100 and really you are still getting a not so great quality Chinese bike.Then over to craigslist, find a Yamaha XT225 with 900 miles on it and asking $2500. Or wow a DRZ-400 for $1800. If you really want to get dirt serious, several 250cc 2 stroke dirt bikes for under $2500.A friend of a friend got their kid one of the $1100 ish Amazon bikes ... dad not so mechanically inclined, neither is his kid ... they had a good time uncrating it and sorting out how to get it together ... watching youtube videos ... I think it took them 2 weekends to get it all together (vs. the 2 hr times on youtube, but they weren't in a rush, didn't spend all day on it, etc). It worked for ~4-6 weeks, then had problems, has now sat for 3 months as they don't really know how to sort out the problem(s) and don't want to spend money paying someone to fix it. Maybe one day they will spend a few more weekends together and get it sorted out. Any maybe that dad/son bonding time is pretty cool and worth $1100. Maybe this will inspire the kid to gain some mechanical skills/knowledge. Who knows. But certainly not the best plan for a cheap fun bike to ride around on for years and years.
Could not be more impressed with my G/F Kymco Spade 150 CC FI motorcycle. Reminds me of old standard MC of the 80's. Actually made in Taiwan but has corporate office in South Carolina. New $2700 with 2 year warranty. Runs Great for grocery getter.
