Tuning a Yamaha Morphous

Hi all
I have 2 Vtwin motorcycles a Honda Helix and a Burgman 400
The burgie is quick, but frankly I dont care for the seating position
I love the Helix and its comfort, and love the seating position,is the yamahas seating like the Helix?

I am very intrigued by the morphous, I have the chance to get a nice 2006 really cheap
I have a lift, a garage and all the tools and can do my own work, I know with the helix, a simple rejet an added pod filter will give you some more performance
Is there anything with the morphous I can do other than play with variator, rollers and clutch?
I was thinking of getting a nice akropovioc or a nice thumpy exhaust, can you add a power commander or any ideas that would compliment a nice exhaust I can add to this bike for higher air flow, intake and just a little more power?

TY all

You could do what I did- swap in the whole 400 from a Majesty. Easy swap. The head from the 400 will bolt right on to the 250 but you might want to get it cut to raise the compression. You could also send the ECU out to get re-mapped.

I was thinking of doing that with the 400maj, I would imagine it would be a good increase,,,,is it a whole engine swap with the tranny and all or you just swapping the top end and leaving the tranny and CVT?
I did the complete swap. It turns the Morphous into what Yamaha should have done. It is almost completely a bolt in swap. The only thing is a gear from the rear needs to be swapped out. Here's a link from a long lost How to:

Thanks, I just got my Morphous today!,,,,an 06 black with 14k miles,just got home aftger 8hrs of driving,,LOL,,,I have not gotten it on the lift for a full inspection yet,,but initial lookover was good,, tires had good PSI, oil was good,,,,took it for a little test drive, no plates yet
5 min off the seat review
Not a fast as Helix off the line BUT faster so far after 40ish, smooth as hell, speed is really hidden and stable, comfortable as well,,low profile and center of gravity,,,,,I like it so far
I only saw 50mph but tonight ill go more,,,,,I definetly need to give it a full service, needs new tires for sure,,,it has the power pure SC on now, which I know are quality tires,,, I may stick with a new pair or even the pirelli angels,,,,it looks really clean in some aspects, but some scratches I think ill be able to repair or replace, but engine wise and tranny wise, looks good so far and SHOCKINGLY the speedo was nearly spot on to the MPH, I like that!

You have any recs for tires?
AND if I need panels webike maybe? Ebay?

Im gona get it registered and serviced,,,,,but I really like the idea of the MAJ 400 in it, and I can do the swap myself
See less See more
I Darksided my Majesty recently. It drives awesome, with a 165/65-13 on the rear.
