Wanted to do a comparison of the 70cc class motors now that the specs are mostly out on the GP-76.
The GP76 is only 0.213"/5.41mm Wider cap-cap, 0.19"/4.826mm Longer Mount-Hub, and 0.088lbs/40g Heavier (without muffs or ign) than the DA70. so less than 1/4" dimensionally and under 1/10lb heavier. Not bad GP, not bad at all!
I'll update this as more info becomes available.
All motors listed below have the same firewall mounting of 66mm H x 78mm L. All come with Genuine Walbros, and NGK CM6 plugs. Weight shown below is without muffs/ign.
