strongweld Posted June 11, 2018 Report Share Posted June 11, 2018 Just spent 10 hours doing Dyno runs, went from 38 horsepower to 102. 10mm stroke, 77mm bore, 26cc domes, 185 compression, 35 pwk, 200 deg exhaust timing, 12 degree timing advance, DEG needle 3rd clip, 50 pilot, 130 main Every time I lowered the main jet it made more power, ended up at 1210 egt with 130, didn't have anything smaller to try, spent 10 hours getting this far. Crazy how small of Jets these are Sent from my Moto Z (2) using Tapatalk Quote Link to comment Share on other sites More sharing options...
strongweld Posted June 11, 2018 Author Report Share Posted June 11, 2018 Old school JD ported 350 with 28pwk's and paul Turner mid pipes made 69 horsepower (girlfriends bike) no time for tuning hers, but it ran great alreadySent from my Moto Z (2) using Tapatalk Quote Link to comment Share on other sites More sharing options...
strongweld Posted June 11, 2018 Author Report Share Posted June 11, 2018 I am amazed at the difference in jetting between motors, I used recommendations from here, 160's is where others are.Sent from my Moto Z (2) using Tapatalk Quote Link to comment Share on other sites More sharing options...

strongweld Posted June 11, 2018 Author Report Share Posted June 11, 2018 My builder thinks I may have another 2 ponies if I went down one more step on the mains, but we didn't have any smaller Jets. The EGT of 1250 would have been perfect. Sent from my Moto Z (2) using Tapatalk Quote Link to comment Share on other sites More sharing options...

n2otoofast4u Posted June 11, 2018 Report Share Posted June 11, 2018 I'd be really careful with that in real life! Out of curiosity, where are you from? Quote Link to comment Share on other sites More sharing options...
