    Rebuild time

    I already have a stock cylinder 67.50 mm BDT ported cylinder ,short rod . ESR pipe and 36mm carb on my 85 Atc . I am very happy with how it runs . I purchased an 86 Trx and I’m want to rebuild the engine on it and maybe put it on my 3 wheeler . Really have my heart set on a 4 mil stroker . I can split my own cases no problem. Thinking about 310 esr cylinder because stock ones are getting crazy . But I do have a stock cylinder . Maybe 330 pv no stroker ? I already have a 38 mm carb . I mainly ride woods in Ohio , so low end is a plus . Suggestions? CT racing had some really good advice and suggested a 330 pv no stroker he said it will pull like a tractor 🚜

    I am partial to Hybrid Engineering. Pete has never let me down. He did wonders fixing 310 built by another guy. Then he built 2 fantastic stock cylinder engines for my boys and a 391 for me. No gimmicks! No drama! 100% satisfaction

    Nothing but great things from Arlan and Pete. I have been running Arlan's motors for over 20 years. Anytime I get a new (new to me) bike, it gets sent to him.

    Best regards

    for woods oem is one of the best way to go..if your going to get an esr cylinder 330+ is the way to go.+4 crank is a good thing but cylinder has to be ported for that.
