Hi , what are my 4 stroke options for a Kitfox II 950 gross weight? Currently with a KFM 112 and needs to be replaced. Thanks for your input.

Check out the HKS its a great engine I have 490 hrs on mine in a Model III 1050.

Flying a HKS Kitfox III and a Champ
I second the HKS 700E!
hks is very good engine but just the part is
not easy to have ....japon is not rapidly
but with a good engine, you don't need a part

Some have used the GEO conversions with a raven redrive
Im waiting to see if someone is going to use the new ecoboost fiesta motor, 3cylinder 100 hp plus motor that will fit in a suitcase
Ive only seen one, but it was a smaller harley motor mounted on the nose of a plane (ultra light)
Maybe we can get him to do all the research for us... But seriously, it depends on whether you want to spend a lot of time doing a retrofit or get back in the air quickly. The HKS has a lot more support than any of the other 4 stroke options except the 912 and will get you back in the air quicker. Engine mounts and cowling issues aren't as big a deal.
Possibly George he wanted options, just throwing some out there, the bigger the " box" of options, the better chance one has to meet their needs, financially, time, ability, as for research boeing uses inline 4 cyl. auto 2 liter motors on one of their hydro planes, experimental yes and of course Boeing has allot more in their " experimental fund" then we do, it's no different then the geo conversion with exception to injection is more common now then when the geo's where first used
There is another option i just remembered, Larry Smith uses an industrial motor with his own redrive and his own prop ( culver) on his " backyard flyer" i havent followed what he has done as for engine options on heavier then ultralight planes, but he can retro fit a redrive system on just about any option you choose
Larry Smith 'Valley Engineering" 1 (573) 364-3611
Or do a search for " backyard flyer"
