Wondering about this ported 62T

[Zero Client]

So I've got this 62T lump in a WB1:

Basically a 701 WaveRaider base but modified:

+1mm bore 718 woth ProX Pistons by LPW
Riva cylinder porting
Stock 38mm Mikuni carbs jetted with Ocean Pro FAs - 75p, 137.7m, 1.5ns, 95g, 1 turn
Protec pipe
ADA Girdled head with 35cc domes running 170PSI (Porting lowered compression)
Waveraider waterbox
Dual cooling from the pump using 3/8" line both going to the manifold. Front over-board, rear through exhaust then split half overboard, half into the stinger through a 2mm orifice.
Advent CDI box made for RIVA so its like an MSD
Ignition on the stator set to stock. No advance.

So, the engine seems to be running quite warm with this setup. Sure its in a WB1 which is a bit of a round-about. It runs mostly half to full throttle because it goes forward rather than up like a superjet.


Any thoughts or advice to the cooling matters?

Last time you pulled your plugs, it seemed quite lean IMO. Your plugs had almost no color to them and they were dry. I'd richen it up, on the top of your happy with the bottom.

The top feels good and the plug gets very dark in that regard, but low throttle does seem to be lean. 75 low jet puts my idle on the verge of load ups so I'm going to try a lower popoff next with an 80g Spring. This will give 38psi on 1.5mm n/s. Hopefully that will help lower tge burn range without causing the idle to 4-stroke.

What temp is the cylinder and pipe chamber? cylinder should be around 140 and pipe should be good as long as it is not melting the coupler.

Celsius or Fahrenheit?
