1229 Gs upper rpm break up when warm or hot under load..

[blowerbike]

1229,
vacuum carbs or mechanicals?
rubber in the top=vaccum.
twist throttle and slides move=mechanical.
watch out for ray..
he shoots for the brown eye

do you run a dyna shift minder?

splitter wire on the shift minder? cross fire from a bad diode letting reverse bias connectivity.

Could not find time yesterday to post but got just a few min tonight.. Here is a link to the GS the first night I had it..This was after 3 back to back passes with the Dyna limiter set on 12k! My friend Tommy Bost riding as I did not have my gear with me.. He is short shifting at point of break up and runs it out a little on the top end..also second link attached is same GS first pass cold running the R1 Raptor we race that runs 6.70's on stock wheel base with only wheelie bars. RapidRay I would gladly like to speak to you on the phone..Tell me when is best time to call.. Thanks Blower Bke also for all you hep and info..Keep it coming. I am open to all ideas..I have always wanted A GS and cant wait to get this one dialed in..

you need to post a picture of that bike...looks familiar....
2nd pass sounded ok?
something easy to do is unhook the power wire to the rev limiter(dyna 200/300) and see if the miss is gone.
if a person was to leave hard on that bike it would fly when the miss is fixed.
your buddy just kinda dogged it out of the gate.
PICTURE PLEASE

[1229 monster]

Still does it with the limiter unhooked.. Yeah he dogged it becasue we did not know what to expect..The vid of him against the raptor was the first pass,the single was the last after a 3 run back to back.. let me find a pic

[1229 monster]

the recipt for the motor work..The number is the second owner to before me.

[1229 monster]

another pic..Not sure about anyone named T..I bought it from a Morris in monroe NC

[blowerbike]

question?????
are you racing it with those air filters on?
are those chrome mesh cones?
kinda important...

[blowerbike]

if you didn't remove those 28 dollar filters at the track...
that could be a big problem.
i was gonna say ....go take them off and ride it up the road and see if its fixed.
inquiring minds want to know.

[1229 monster]

Removing the filters really made no change..the filters have the chrome tops yes..and as far as rocky and bullwinkle tuning,i believe they could do a better job than previous owner..and those runs were just a test..trying to get a base line on bike..will not run it again till I get it right..we normally run the raptor..

[blowerbike]

well crap....

[1229 monster]

I will get more in depth tomorrow..voltage test, compression test, see wats in the carbs,etc...i will make a run cold, let it warm up get a temp and really try to narrow the rpm range of the issue..work, and leg injury kinda kept me behind this week..thanks again..and will also for chits and giggles unplug the tach and run it..

[1229 monster]

Sorry I have not responded back. I ended up with a surprise blood clot in my leg that traveled to my lung and had a little stay in the hospital.. Soon as I am cleared to get back to things I will be posting info and test results on my GS. Thanks guys..
