OK so its come to this. I have a 2007 LTR450 that will now start but not accelerate, have rough idle and dies soon after. When I first got a hold of the bike the the fuel system was severely crystallized throughout. Flushed out tank replace fuel sock, after market fuel pump, fuel pressure regulator all replaced. Flushed out injector as best possible (found out my order sheet didn't include an injector my bad). Spray pattern of inject looks good when activated. Noid light indicates good pulse width. Battery was in horrible shape and was replaced causing the loss of files for the DynoJet power commander 3. Removed programmer to simplify diagnosis. Will be reinstalling once bike is up and running. Having troubles starting and running as previously stated but am able to manually inject fuel with syringe and bike will run, so spark although appears weak will run the bike. Short of an injector just what am I forgetting to look at or inspect. Seems I have been chasing my tail on this thing and am looking for a second set of eyes as to just why something so simple can spin my head around for this long.
