She's alive and just need to tune carb and build a expansion chamber that will work with the 490. Does anyone know how to design an expansion chamber?

Welcome aboard. Nice machine! I know there is some information about some members who have built pipes before, trying to find a thread.

Thanks I even able to make the intake plumbing fit correctly no air box lid and it livened up

You have any better pics of how you did the carb / air box? My brother just bought a yz490 motor for a tri-z swap

Use an 87 intake manifold and a 90 silicone

Www.siliconeintakes.com bending reducers I used a 2.5'' by 3'' 90° when I cut the ends I cut them on angles to make up the offset

I really like your trike. If I could have a big bore trike it would be a 490. Have you have the head modified at all? How about you post some video of it on the pipe?:naughty:
