If it will not pull over 7000 I imagine you are running out of power. Keep in mind a 540lb motorcycle with 80hp is going to run out of steam before you do!!

That seemed to be topped out because I could rev it to the red line at 9500 but there was no more speed coming out of it.
Even if the speedo was off a bit it was still pretty fast riding... when you look down at the dashed line on the road and it looks solid, you have to be going at least over that 100 MPH mark.
Something is wrong if that motor won't rev to at least 9000... I ride my buddy's '76 1015 motor quite a bit and it revs past 9500 with no issues.
PS - not a good idea to look down at the road while riding...

He said I needed the high octane to help the bike run better.
The speedo and tach look stock to me, so not sure if both are reading correctly or not, except I did go through a traffic radar "box" that let you know your speed and said I was doing 23 and the speedo was at 25. Might get worse the faster the bike goes?
I am glad I found this place with such a vast knowledge base and maybe I can learn to get the bike where it needs to be and KNOW it is right.
Thanks Again !

thanks for the input guys ! 1st off,the bike as far as I can tell is bone stock except the kerker 4-into-1, the free flow air for the carbs. I am not a mechanic but love to ride this thing and the guy I took it to is a motorcycle mechanic that "claims" he used to work on these bikes new.

just my .02, but that bike should easily rev to 9k....probably needs re-jetting......pods and a pipe require at least 2 up on the pilots and 3 on the mains if i remember correctly......then theres the baffle in the pipe...a lot of variables...if that thing wont pull cleanly to 9k, dont push it untill re-jetting...you are way lean and you will eventually grenade a piston....again, there are a lot of variables here....stock ignition/aftermarket, plugs good, carbs in a good state of tune, good battery,valves adjusted correctly, etc.......

I believe he's wanting it to rev to 9k in top gear, but many of these old bikes wont pull red line in top gear.
