My friend keeps saying he thinks he will smoke me the whole race on his stock 85. I told him no way. I’m running a 143 big bore, v2 race head, fmf full exhaust, u flow air filter, 26mm mikuni carb, 14f 39r sprockets, and bbr rev box. Also wondering if anyone knows the top speed of both bikes. I’m guess the stock 85 would hit around 65. Big bore 143 maybe 60 with that sprocket setup. Just wondering so I can really smack talk him with confidence however I really do think that until he hits powerband I’ll be ahead for a while. I’ll update if the race ever happens.
