First the test bike (mine! ) was run up and the jetting checked against previous data. The initial run was within 1/2hp of the previous test, but indicated the carburetion was slightly rich, so the top cylinder was dropped a size, and a baseline run was made.
The blue trace shows my MC21SE with Ethos Design race pipes. The red trace is from the "chosen" NSR-WORLD pipes, with no jetting changes - only the pipes exchanged.
As you can see from the graph, the NSR-WORLD pipes don't quite rev as far as the Ethos pipes, but from 7000rpm onwards they are producing better power. At 10500rpm, where it really counts for most of us - especially on the road, they are producing over 4hp more!
We have an "over-rev" pipe too, which on exactly the same settings too, produced 67.4hp @ 11500rpm (some 2.2hp more than the Ethos), but we considered them too peaky for road use, although this again was with unchanged/unoptimised jetting.
Pipes are mild steel and will be finished in satin black. Prices are yet to be confirmed, and will most likely be manufactured to suit MFactoryWest silencers, although I am looking for a more cost-effective alloy alternative. I still envisage a price of approximately £250 + silencers.
We would like to hear from MC21 owners via e-mail only, who are interested in pre-ordering please.
Depending on interest, we will consider other models at a later date. We have MC16, MC18, and MC21 "jigs"!
I wouldn't mind trying the over-rev versions on my 300 Andy... Or your phat ones that you've chosen even! _________________ NSR300R - Why did i ever have a 250...
Hi Moggy.... yes, you probably will have to make some small changes to fit them. But hopefully it will be just a small bit of trimming on the R/H lower fairing where the pipe emerges. This is because standard pipes are squashed flat at this point, and these are nice and round. And maybe a little bite from inside the front V-piece louvres where the pipe passes the front cylinder head.
You'll get these problems with pretty much all race pipes for the 21 unfortunatly.
Or space the fairing out if you don't want to cut it. Works equally well, though does generally require a strap to join the left and right halves at the rear. _________________ MC21SP Plaything
