Anybody gone from a road 2.0 to a road 3.0 on a modest 177 kit?
Just wondering if you had to adjust timing, if so by how many degrees?
Jetting, did you have to go up slightly on your existing main jet or is it about the same? I only see stats for power increase on p210 rigs etc claiming 10-25% extra power so wondering what changes needed from road 2.0 on 177 (a DR) if any? Thanks.

I cannot remember my jetting (24/24e), but my DR runs at the factory IT mark with a BGM BigBox Touring. Never felt the need to change the timing. Scoot is a 2012 PX150 for the record, with the Chinese ignition.

Think I'm either 120/BE4/122 or 140/BE5/122 with a venturi in place of the filter, but it's been 2 years since I took the carb box lid off.

Going from box to box won't require a timing change.

Even going box to pipe *probably* won't require one, but if your peak power shifts significantly (>1,000 RPM's), you might want to advance the timing a degree per thousand. Even that is probably not necessary and will cost you a little bit of power on the low end, though.

I think I might have upjetted a couple points when I went from a Sito+ to a SIP Road 3.0 on my P200, but I was still in the carb tuning process, so that might have been catching up on the jetting.

Roger that, im on a 122 mj 24mm 177 rig, ive got a 124 to hand. Did you find much difference with your road 3.0 over your sito+. Ive got a road 2.0, its been fantastic exhaust but its near its expiry as noisy, hoping the road 3.0 isnt lacklustre like the polini box. If they claim 10-25% more power on a kitted P2, then reckon 2 point MJ rise will be bullpark for my setup.

I found a definite difference with my swap, especially the top end rev's. I saw similar results going from a SR2 to an SR-XL on my VBB. It's definitely engineered to rev out.

On the P200, I have a completely mis-matched setup on that motor (Malossi 210 MHR, but otherwise stock except the SR3 and widening the intake a tiny bit), because I've never moved the build forward because the Smallstate has sucked up all my scooter funds and the VBB sucked up most of my scooter time.

Interestingly, the P200 and the highly tuned VBB are pretty comparable to each other, performance wise. The VBB is 17 HP, the P200 is more like 18-19, but it's much, much torquier, which pairs really well with the longer gearing, even with a peaky top end. I need to get a GSF Dyno for it, but keep not getting around to it.

Thanks chandlerman, you got me bought into getting the road 3.0, it has to be way forward for me, seems silly to buy another road 2 if it's yesterdays news.

Definitely! I was super impressed with the road 3. I didn't do anything jetting/timing wise switching from the 2-3. So far so good!
