Hi Geoff, interested in the helicoil and stud setup you use for the exhaust flange. Here in New Zealand, most people run cap head bolts with lockwire. Look forward to the dyno results!

Love the new intro Edit 👍🏁🏁

TY Scott!

[@rwworonowicz]

Thanks!

[@robbinsracing801]

Thank you too!

Is that O2 sensor too close to the end of the exhaust? From what I have read it needs to be at a specific angle much closer to the exhaust port. I have wanted to do this for my son. I am excited to see how it works out

[@robbinsracing801]

Its a self heating sensor so it doesn't need to be near the exhaust port. Only thing I have heard is that negative pressure could suck air into the silencer and lean out the readings. Just going to have to see how it goes.

@@robbinsracing801 when you need to adjust the mixture are you adjusting the float or needle or fuel air screw or all 3?

[@robbinsracing801]

@@michaelmurphy6687 All 3 although in the past I set the idle mixture screw to 1.25 turns out and forgot about it. After I get this thing broken in I plan to start with carb setup first. We'll do a dyno pull for each of the needle clip settings and then as many float settings until the AFR is just right. We can also see how the Idle speed screw changes AFR too.

Where did you get that red carb cover for when the filter is removed?

[@robbinsracing801]

I've had it for years, hope this is the right one.. www.bmikarts.com/Filter-Adapter-Cover_p_475.html

Where did you get the valve seat cutter kit?

@@robbinsracing801 Thank you, what's the part number for the 30 degree cutter? The Briggs kit they sell only has a 45 degree, I want the 30 degree cutter too, just don't know the part number.

@@KCDustRemover Yo my bad totally forgot that the 30 was separate. PN: CU126
