bontempi Posted February 12, 2020 Report Share Posted February 12, 2020 It´s been a while since i was here! I just finished my rebuild of my new Honda Aircooled Mono TLM 250R (1988). A quite rare Bike and it seems to be underrated in my opinion. I was looking for an air-cooled mono and wanted to have a disk brake at least on the front. And i was in the mood for a japanese bike again. A few days before christmas i bought this bike in really bad condition. Parts are not easy to find, but when you get a little creative a lot is possible. I managed to find a wössner piston of a 250 Rotax that was available in 74,50 and 75,00 sizes. The main difference was the 18mm Piston Pin and a different shape to the dome. Also there were no holes on the backside of the piston. So there was some work required. Now the bike is almost finished, and i am very happy with the result. The bike feels very light while riding and has good power and a good throttle response. I was thinking of taking off some flywheel weight when i first saw this heavy piece, but i think i will keep it that way. cheers Bernie So here´s the bike: 7 2 Quote Link to comment Share on other sites More sharing options...
mattylad Posted February 19, 2020 Report Share Posted February 19, 2020 Interesting information on the piston. It does however seem a lot of work. Does anyone else have suggestions to other pistons that may be fitted. Quote Link to comment Share on other sites More sharing options...
