Flat Spot...........

[Fluxy]

Can anyone help, I've had my STD storm for @6weeks but it has a massive flay spot at 6500revs and struggles to rev past it (was like it when I got it) to the point that in top it only does @120-125mph. Any suggestions would be appreciated cheapest first as I spent all my dosh buying my storm..................Doh.

ah ehm, well i guess its over to you wayne!!
have you tried looking into the carbs? they might have sucked a
bird or perhaps a passing small child ,
but seriously this could be a fuelling problem
im sure del will know what it might be

If you havn't had it long I would strip the carbs down and check everything out to see what's in them. Don't know the history but if you bought it second hand the guy before might have stuck the standard cans on etc and left the jetting/needles etc in maybe for race cans and K&N.

Definately strip em down and take a look, check filter too, for over oiling and drain the float bowls etc.

Thanks Del will have a look in the carbs, what No. are the standard jets/needles?

Will let you know how I get on, Wayne if you think of anything else let me know.

By the way it still wheelies like a goos un....................

You will know the standard needles they do not have removable E clip's for adjustment and dynojet,factory etc will have groves in them at the top to raise/lower the needle. Main jets I think are #178 and #180, not sure is at work. Pilots #45. Also check to see if the slides have been drilled, normally has two holes in the bottom but dynojet get you to drill a third.

Another check before you take em apart. Once the airfilter is out, open both slides by hand, (ie finger the throttle body) and check they close smoothly at the same speed.
