Ride it to find out - if too small it will loose power at the top end of the rpm range - you could probably up the jet 2 sizes and not hurt anything.

Thanks I ordered 160-170mj any thought on why it would be a 155 the quad came with the mods, in comparison to other 400s with similar setup it seemed small 165mj seemed to be average.
