Jetting following addition of a reed valve?

[alanscottj]

Been out for first rideout today after fitting reed valve. Scoot is running great and egt and cht is in a good place. I was told that I would have to up jet after adding the valve, as my scoot was already running rich I think it is ok in terms of main jet. But, when I was on the rideout and started her up to leave she stalled twice and was difficult to restart. Once it started I had to run with choke on for a minute or so to keep her going. Once I got going she was running pefect.

So, given that I have added the reedvalve what recommendations has anyone got in terms of my jetting? Needle clip position etc.... Carb is a delly 30mm PHBH.

Any thoughts muc appreciated as always

Yes mate, boost port and piston has had windows and skirt cut. Runs great but not great starting.

For poor starting would I be looking at the pilot?

for about £80 I would get it on the dyno cheaper than a holed piston or seize

I think I'm set up safe through the Rev range. According to my EGT and CHT I am ok. My temp never went over 530 whilst sitting at 65, my only issue is when starting.

Did you get your jetting all sorted Alan?
