You will sacrifice a bit of low-end power and the bike will no longer idle (RS carbs have no idle circuit). _________________ Paul Herr

MY BIKE PICS
On your next order get the carbon fiber reeds and Hi-flow cages, then mod your airbox. With those pipe you think it's a different bike. _________________
already have the carbon reeds installed when i purchased the bike.
might drill a few holes in the airbox, and then rejet the bike
or i might just see how it goes with the pipes first..
maybe you can give me some good base setting for jetting Jeff,
similar location and such, would probably be spot on _________________ Koren
2 Strokes and I'm Off
hi maine2stroker,
how much extra power will give the rs carbs on a 300cc nsr? you know?
in this winter im going to build 38er keihins on my nsr300.. im intrested in how much power it will give....
The 300 works very well with stock carbs. Better with bored out stock carbs, and better still with big and juicy 38's!
However, the jump from bored stock to the 38's is not as good as it sounds without some more mods to the porting. Basically the port timing and area are more aimed at use with the stock parts.
I've got a pair of cylinders in production with porting worked out for BIG carbs and higher rpm. We'll just have to see what happens.
where I have to start to jetting the 38er Keihins from a 92 RS on the 300cc kit? I have to buy some jets, which size (of course on the safety side to go then smaller) i need maybe?
G'day
I raced a NSR for a couple of years, a 1989 MC18 with various MC16 and 18 engine bits.
I put some racepipes on it, and was impressed.
Then I got an Aprilia RS250.
I put Tyga's on it. Impressive.
I put PJ38's on it, off a 1990 Honda RS250.
Mate. I wish I had done that to the NSR!!
They give at least as much as putting the pipes on did, and its a heap easier to work on them. (They're in a enclosed fibreglass airbox)
