arena314 Posted July 1, 2018 Report Share Posted July 1, 2018 Hey guys anyone here ever work on or have any experience with Yamaha blasters? I just picked one up very cheap and am having powerband issues. Never had any issues with blasters I've done a top end on one before but never experienced diagnosing issues with them. If anyone can give me some advice that would be great Sent from my SM-G965U using Tapatalk Quote Link to comment Share on other sites More sharing options...

arena314 Posted July 1, 2018 Author Report Share Posted July 1, 2018 It has a filter with no lid and a pro circuit pipe and silencer and tors delete. Otherwise it's all stock and has a fresh rebuilt top end. It idle and revs fine in neutral but the idle hangs bad at times and it has no power when you ride it. When you mash the throttle it just sounds dead it doesmt big or break up it just makes noise and doesnt hit power band. Feels like it's way rich or the carb is dirty. It has a stock 32.5 pilot and a 250 main jet and I took the whole carb apart and sprayed over a can of carb spray through every hole. Also put a fresh plug in itSent from my SM-G965U using Tapatalk Quote Link to comment Share on other sites More sharing options...
fastbanshee8 Posted July 2, 2018 Report Share Posted July 2, 2018 Have you checked it for air leaks? It's lean, or the idle wouldn't be hanging. Pressure test that engine, and if it's sealed up good, then start rejetting the carb. Quote Link to comment Share on other sites More sharing options...
arena314 Posted July 2, 2018 Author Report Share Posted July 2, 2018 Well I pulled the reeds to inspect them and see how they look. I could see light through the pedals so I flipped them and it didnt help bc they still had a slight gap so I put them back in anyway to see if anything changed and noticed when I took them off there was no gasket or rtv around the red or red boot so I rtv them back on which fixed the idle hang so that could of been my air leak.. but engine still runs the same it womt hit power. I might buy new reeds and go from thereSent from my SM-G965U using Tapatalk Quote Link to comment Share on other sites More sharing options...
Buckeye513 Posted July 2, 2018 Report Share Posted July 2, 2018 What’s compression at?Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
arena314 Posted July 2, 2018 Author Report Share Posted July 2, 2018 I'm not sure I havent checked it because he said the top end was fresh and I could tell the jug looks new bc it has fresh black paint on it. I was thinking though I probably should check compression anyway what's reasonable compression on a stock blaster?Sent from my SM-G965U using Tapatalk Quote Link to comment Share on other sites More sharing options...

sleeper06 Posted July 2, 2018 Report Share Posted July 2, 2018 My educated guess is crank seals or gaskets had an air leak and that’s what fried the other top end . So before you blow a new top end do th proper testing. Does it have the oil block off for the injection Quote Link to comment Share on other sites More sharing options...
