From perth, ordered mine 3 months ago and just got her on Friday , as you can see already blacked her out, made my own bar ends, changed the levers, changed the stickers and a few other small mods, de restriction will be done in 2 weeks View attachment 3751
Have you got any other photos of your bike you’d be willing to share, I’m very tempted to black mine out too but I’m scared I’ll regret it 😅

whats involved in un-restricting the 650? i want to remove the restriction on mine also.
is it as simple as getting a normal ECU and changing the air intakes, or is there more to it???

2 Ways to de-restrict them, have the ecu flash tuned (i went this route) and the intake funnels drilled out, 2) drill out the intake funnels and install a power commander, and have it dyno tuned.

There is a bloke in melbourne who i sent my ecu and funnels to, he flashed my ecu, drilled my funnels out, sent them back with a new air filter and a o2 sensor delete.
It now has between 80 and 86rwhp, enough to get the front wheel up under hard acceleration in 1st (6000rpm+) and it will lift by itself, 2nd with a good clutch kick.

In a video he made, he said the unrestricted funnels are better than drilling out the OEM funnels because they’re shorter.

I was never given this option and was lied to on the day I took my bike in.

He told me there’s no difference except it doesn’t look as clean.

Wouldn't trust Dave @ Dynobike as far as I could throw him.

Funnel length makes very little difference in overall power or running ability so I wouldn’t over stress about it if that’s what he lied about. If they are the same opening size between drilled and new, even 10-20mm difference in length is negligible.

Yep completely agree.
he didnt mention anything about using other funnels, he simply said he will drill out my OEM funnels and flash my ecu.
did what he said, completely happy with his work...
sent off my ecu on a tuesday, had it back in adelaide friday morning...

This is true for peak horse power but not true for torque curve. Longer intake runners make for earlier peaked torque (at a trade off of high RPM torque production) and vice-versa.

You’re talking 1-2 ftlbs max unless you’ve got a system that combines ECU programming, cam timing and intake length changes to optimize running. Even then it’s subtitle unless it you’re talking a large CC motor with a huge intake like a car has.
