hello peeps. My storm on full throttle......well, after some time on a high speed run 140mph+(on a private road of course) seems to drop in power and give off a chokeing feeling??? if you get what i mean, lol!
Anyone had this before??
A friend told me it was something to do with some sort of fuel resevoir emptying and not having time to replenish itself and the only way round it was getting an injection bike, but he wasnt ure of the details. Is this true or is there something wrong????? please help, ben
bike seems to choke itself at full throttle???
yeah, amazig thanks Kaz, alhough im not sure the neighbours think that, might have to get a bit carried away with the dremell polisher on the 'not for road use' tags, they need a good shine up i think,lol.
n, yeah, it does seem like fuel starvation, any easy cures for this problem people, its quite annoying, and could prove pretty dangerous i recon!!

Moriwaki VTR runs a CBR600 fuel pump.
enquiries@revolutionuk.co.uk is where to ask about this.
*edit* from what I've learned:
It should run fine, even when low on fuel in the tank. Check all the fuel lines and vaccuum hoses first. (source: Greg, 100,000 posts+ VTR guru)
The actual reason fuel pumps are fitted to track VTRs is that in higher states of tune, they run pressurised air boxes and need the fuel pump or it won't run at all. A standard bike shouldn't need one. (source: Moriwaki research and VTR racers)
You can fit fuel pumps from a CBR600 or use a VFR fuel tank which has an internal fuel pump. The VFR tank is a simpler job to perform. However, as said, it shouldn't need one, so might well not even fix the problem. (source: folks who've done it)
Thinking from a theoretical point of view, if there's a restriction or partial blockage somewhere, a full tank of fuel exerts more pressure than a half empty one, so the apparent starvation issue would appear or worsen as fuel load lightens, which happens pretty quickly at 140. If this is the case, it points further to a blockage problem. (source: my brain (not reliable) )
Conversations about dyno tuning recently revealed that at high revs, you can develop a rich mixture misfire yet the fuelling can be fine the rest of the rev range. Essentially, it dumps too much fuel in and bogs down. It might just be a case that the fuelling needs looking at. (source: Revolution)
Whatever the actual cause, an email to the Revolution address above will undoubtedly give you answers and solutions.

Voted most likely to be found dead in park bushes following an act of autoerotic asphyxiation.
pinched carb breather pipes maybe??
have u tried the "fix"??

Re: bike seems to choke itself at full throttle???
Mine used to do this quite a lot when it was new. It turned out to be one of the carb slides sticking open causing the bike to over fuel when it slowed down.benny-g wrote:hello peeps.

All I did was remove the slides and polish the edges with a Stanley knife and some very fine emery cloth to remove any rough edges and the problem was solved.
Another time I had a similar occurrence was just after I had washed the bike and got the hose pipe too close to the petrol cap. At high revs it sucked the water through into the carbs. Once it had cleared though everything was fine.

My new ride is a bit of a Howler and I love to make her Squeal
