I would buy a 110 bolt on piston and cylinder kit, a set of .030” head gaskets, 58mm throttle body, 5.3 injectors, the 259 cams and a set of tapered adjustable pushrods. Basically ending up with the tire shredder kit except you already own the heads and don’t have to buy another set. I would also get a heavy breather intake. If you still have the stock clutch spring in it then install a police bike spring (pink dot). This will run better than blowing a bunch of money to run stock 110 cvo heads.

Sorry, I didn’t realize they don’t offer the tire shredder kit for your dyna and have a calibration for it. If your tuner isn’t the “street” tuner it could be tuned using the one you have, but you would need help from someone to set it up then work through the process. The cvo heads and dome piston option wouldn’t be a bad setup just super expensive.

[QUOTE=harpwrench;21978093]Lo siento, no me di cuenta de que no ofrecen el kit desmontador de neumáticos para tu Dyna ni tienen calibración. Si tu afinador no es el de calle, se podría afinar con el que tienes, pero necesitarías ayuda de alguien para configurarlo y luego seguir el proceso. La opción de culatas CVO y pistón de cúpula no sería mala, solo que sería carísima.[/QUOTE

I dont know if I install the kit 92500039 with my heads will give me the 10.5:1, and maybe use the same tune of the high compression kit. and use the se259 cams.
thanks

Yes then I would use smart tune to optimize it the best you can. With the gaskets in the kit you would have about 10.3, and substituting .030” head gaskets would make it about 10.6

it will be the same compression as the shredder kit for the 259? I try to check in big boyz calculator, but I dont know all the parameters to introduce

You can figure on the pistons being .005” below deck, could actually be a slightly more or less but that’s close enough. I believe those combustion chambers are set to 85 or 86cc. Kit head gaskets are .045” thick if I recall correctly.

[QUOTE=harpwrench;21979333]Puedes calcular que los pistones están a 0,005" debajo de la plataforma; en realidad, podría ser un poco más o menos, pero es bastante aproximado. Creo que esas cámaras de combustión están ajustadas a 85 u 86 cc. Las juntas de culata del kit tienen un grosor de 0,045", si no recuerdo mal.[/QUOTE

do you know with the stock 110 heads, the cc dome piston volume with flat pistons? I read maybe 2 or 3cc?
