Anyone know of any problems puting a R26 motor into a R25 fram with R25 transmission? R25 motors are virtually impossible to find in Canada/US , but R26 motors are available.

Thanks

No problems,except the exhaust tube.
The 26 exhausthole in the head was slanting
The 25/2 was straight.
you have to bench a new exhaust tube or try if the 26 tube fits(I do not know this) with the 25 silencer.
