That is correct I am on a 4s. This kart was also run successfully with tag engines as well. I would not say it is softer than other model arrows that have been used in 2cycle classes. Aside from the straight rear bar to accommodate the inboard drive their isnt any 4 cycle specific design changes.
I have also watched an Emmick cobra dominate at gold cup. It was designed/marketed as an 80CC shifter kart in 98. I owned one and won a lot with it. It had a 1 3/8" axle. Frame was super stiff! Front torsion bar welded solid and also a rear bar and extra left side rail.
There are some changes with the 4 cycle Arrows. 1st the wheekbase is 8 mm shorter, and most important of all, the 40 mm axle you use compared to the 50 mm. The wheel hubs are also different., but as I say main difference is axle. Every European or foreign manufacturer uses a maximum of 40 mm for lower power classes, including Yamahas. I guess they know why. Anyway I am sure you are an excellent driver and that can make an even bigger difference than the chassis. Thanks for the info.
