just a thought, I talked to the previous owner, and he seems to think that timing could be off as well? could timing play a role in not reving out properly? if so, how do I check it, and where should it be set at? I forgot to mention, I am running Sunoco 110 fuel, and klotz oil @ 32/1. Thanks again, I love this site!

Posted some time ago, I have had the same issue with a 86 lt 250r not wanting to rev out, but it is much worse. maybe if you all help me to figure out the zilla, it will help me figure out the 250!
