Hd the hydro out yesterday. Been tunning it after the new heads and was havig a problem with backfires. Never opened it up, but was crusing around 4g's, slowed down to idle and a humungus backfire occured. Scratched my head, wiped my a$$ and restarted. Idled about 15 seconds and something came apart. Fock. Further inspection revealed a crack in the left side of the blower case about 4" long. So this one is toast. May go back with a good TR, unless I find a good deal on a new/used 6, or 8-71. TR would be more practical, but we all love the blowers, right? Anyone got a TR or blower?
