NSR 97 Tuning

[Guest]

I own a 97 NSR, this is in norway so i may have other restrictors than u, it has 12 hp according to the papers.
I looked for the restrictor in the intake to the cylinder, there was no restrictor her. I'we orderd a Gianelli exhaust, so i've dont have to wory about that. I am olso gone put in a 135 dyse and sports air filter.
Are ther any other restrictors i should know about???

I've heard there is maybe somthing odd with the exhaust valve, someone says it is fake on some models, is this true???


CDI, ive heard that if u change some of the wires going in and out of the CDI you can get faster acceleration, which wires, and is there a point in changing the CDI unit:?:

I ve heard that if u change carb and cylinder to Malossi 180cc you can get toppspeed at about 130-140 miles an hour.. and ther has also bin made a 0-60(0-100km/t) at 3,4 sec at Rudskogen racing track.

To get rid of the CDI restriction..... but a new one. There is an un-restricted one around. Some of the other guys will know which it is.

i thought someone posted on here a week or so back that he'd tried fitting a Uk CDI to his import and it didnt work.

I may be wrong tho.

Another thing which bugs me is those fake ram air intaks... Looks cool but the only thing going throug them is wires, it gets kind of, fake.

If i where to put the wires a other place and extend the pips and place them directly into the filter boks, wouldent this cause overpresure(sort of like a turbo)

But wil the petrol flow without a petrol pump, i've heard that when there is presure in the filther the petrol wount flow true? Would i then experience problems due to low amount of petrol in the gas/oil/air mix?? the ram air dosent have considerabel effekt before 90m/h

Also there is a company which specialises in Turbo and NOS systems for motorbikes. But these kit 's have only bin fithet for big bikes like GSX1300 Hayabusa. In Bike this month tthere was a special on 3 different suzukis all with bigbore kits, turbo and nos, all with over 200hp.
The Nos kit dosent cost much, is it hard to adapt one to a motorbike? What kind of changes would i have to make to get it to work? I've heard horror tales of exploding nos tanks, would be a real bumer if a tank exploded right under my ass..
Tempting to try it...
What kind of changes would u experts recomend to me, need more pony's and i need them quik..

How fast do u peopel think a fully tuned NSR would do??
spinnin wheel have experience in tuning these bikes and they said if money wasent an object u could tune them to do ca 140m/ph

Looks like the SP1


Also this is not a motorbike but it's pretty cool..

thatb sounds like some pretty cool shit. i dont know if NOS wouild work on an NSR, and a 10 second boost would probably destroy your engine. i like the ram air idea if you can get it to work, but you might need to fit a bigger carb, or at least bigger jets to compensate for all the extra air.

if you can afford it go ahead and chuck loads of stuff on the NSR, but bear in mind it would be cheaper to just get a bigger bike.

It is very hard to NOS a single. Doubt you could find a garage to do it for you! A twin is hard enough to do...

Hi

Preasurising the airbox is difficult. The trouble is that a carb works by have a small restriction, and the air speeds up to pass the restriction (same theory as an aircraft wing). Faster air is lower preasure. So the low preasure air in the carb and the normal airpreasure in the float bowl forces fuel up into the airstream. PReasurise the air going through the carb and it wont draw any fuel up, however much you play with the jetting.

Normal way round this is to vent the carb float bowl into the airbox so that it is preasurised by the same amount

All the best
