375hp banshees Posted May 2, 2021 Report Posted May 2, 2021 Don't know about at 1400, but that seems fat on both. did you plan on ditching the Box anyway? you didn't over oil your air filter(s) did you? Quote

caleb90 Posted May 2, 2021 Author Report Posted May 2, 2021 compression seems low to me, but it is a fresh bore. maybe pick up 10psi? idk Quote
375hp banshees Posted May 2, 2021 Report Posted May 2, 2021 Yeah, didn't catch that part, gauge has alot to do with that tho. Pods are nice to tune with , but once you tune it, you shouldn't need to do much & a box gives you more riding style protection. Quote
