@herrjugsracing7816 Does it matter which 4 mil crank I buy to be compatible? What would u recommend. I still need to have mine on pump gas also. Can't get race gas where I live
The dome will be the hardest to find and get right. Lucky for you I keep pump gas domes and cranks for that 421 Athena setup. Email me at kev@herrjugsracing.com and buy the crank here. www.herrjugsracing.com/new-crankshafts.html
I'd like to find a IT490 to install in a yamaha blaster. If you find one let me know. Thank you. But open to other air cooled options, idk what's your take on the old RD400 for a blaster if given a full port n polish? Like to stick with 91 octane
I have no idea. Not far off stock cylinders I would guess. They will cross over to 4 and 7mil strokes without getting outside the working duration for making good power.
Do you have a number I can contact to get a price to be able to send my motor in. I’m looking forward into a dune set up away from the stock size motor
I have this athena kit on my 2008, I'll be watching this series closely so I can do the same build . Love your videos
here is one I did a while back. th-cam.com/video/4gU6SGVAMDw/w-d-xo.htmlsi=QSz7QvZ10xc478da

I much rather have an RD400 than a Blaster.
@@herrjugsracing7816 true as would myself, but I see just a old motor forsale on line. Just curious if that be a better option
i want to build a +7 stroker with stock RZ powervalve cylinder
what are the cast port timings on the Athena's?
