stroking a 77 sportster

I bought a 77 xlh this spring; got it for 1400 bucks. The owner parked 3 years ago in his shed. The bike is bone stock with turn signals still on it. The perfect bike for me to stroke. I have a 76 shovelhead stroker 84ins.; but have always wanted to stroke a sporty. From what I;ve read and talked to a few engine builders going with a 4 5/8 stroke is great but hard on parts. 4 7/16 or 4 1/2 stroke are alittle easier on parts and reliable. Anyone out there have any experience with stroking a older sportster..

it would last forever no matter what you build if your wrist could not rotate, lol. More torque= breaks parts faster, good luck

I owned a sporty that was max out to 114ci lots of fun but spent a ton of money on Trany parts and sprockets including beefing up the frame at mounting points . The largest I would go if I was to do it again . 100 ci s&s kit is very nice I would use nallin valve train set up . His spotter cylinders are very good . Not his twin cam stuff . Sportster stuff is top notch . Call and speak with Brian or Andrew very smart when it comes to sportster endurance motors these guys have a lot of bikes that run Daytona and have been at it for years. And run in the top 10. Don't guide yourself about the rep you hear on the internet from none engine builders . About the parts they sell . The stuff is top notch for sporty motors . There is a lot of do it your self guys that don't know how to prep and clean . Or do not know how to read a mic and then blame the parts for faliure. Good luck on what size motor you decide to build . Be prepared to spend a shit load of cash . And we can help you do it ! Enjoy the burn outs!
