Nah, I really figured out it was mostly just the incredibly rich "wet" map.... Moreover, the 2019 maps use more fuel than the 2018 maps.

I also have a Montesa 300 RR and no problems with injection. I mostly use the Ossa and I bought the Montesa because Ossa is no more in production and I fear for when I will need unavailables parts. It is very sad that Ossa could not continue to improve this incredible motorcycle. Yes, a real shame. I also liked my 2014 Ossa.... Whenever I see a rare Ossa at the races, I can't help but stare and feel a little nostalgic. But I'm also happy with my Vertigo! Quote Link to comment Share on other sites More sharing options...
phildirt Posted January 7, 2022 Report Share Posted January 7, 2022 Got a 2012 Ossa 281i new in 2012 and ran it until 2020 when I couldn't get parts and picked up a used 2013 300 and am still riding to this past weekend. Have had various issues but none ever fuel injection related. Weekend warrior status fwiw. Quote Link to comment Share on other sites More sharing options...
