Dont know yet and afraid to find out. Will figure out how to deal with that whenever it gets approved in CA. Dealer thinks it may take a while-
Seems reasonable to drive to AZ or NV and have a dealer do the install, then drive home. I just have to wait for initial two year warranty to end.

121 hp and 131 torque? I guess that is the moco's idea of a sleeper!

Wonder if some of the aftermarket guys will run the cylinders and heads with some aftermarket cam and exhaust would be interesting to see what it can do without trying to make epa regulations.

I posted this back on October 2, 2018 on the topic "how big can you go".


"My local Harley said at their schooling by the MoCo,  they were told that the current M8 was built to handle up to 130ci without case mods. But as of yet they have not come up with anything larger than a 117 ci displacement. I can only assume it has to do with EPA compliance issues. But they said they were also told, "bigger is coming". They are thinking that the 114ci will be the new normal powerplant with a 121 or 124 offered in the CVO."

I missed by 1 cubic inch.

Does the cubic inch bump up correlate with how many years it'll take to make it reliable?

I think all these MOCO big bore kits are awesome for the people who want to get it done and keep their bikes under warranty... Unfortunately I could not wait and had my 128 Big bore kit completed this week... Have to at least give Harley some credit for trying to make power with such strict EPA laws, cannot BW easy....

Do you have the numbers and the dyno sheet?  Inquiring minds want to know.
