Hi rocketeers problem solved. Seems like the problem backfiring at the throttle body and popping out the exhaust was a dirty crank position sensor. Looks like you were right Atomsplitter from the first post, taking me this long because I broke that Bolt taking it out, I drilled it out and threaded a bolt back in, hard to do Under the bike not much room and upside down. Didn't have the right size bolt so I had to shim it up with some washers to make the right length. Hope you like it Turbo

had to take my exhaust off the left side get the fill plug out man that thing was on there good and I torqued it on the last time. Now it's just change the oil and the brake fluid and I should be good for a while she's running great again. PS I'm going to do another compression check just confirm want the mechanic said about the number two low cylinder. Thanks for all the help rocketeers hope you had a happy Thanksgiving. And you guys over in the UK, hope you had a happy November 27th
