allso can be N2

[fozzy17]

So is it's the same a n2 the stator should be the same as a n1 that's the motor going into my n1 chassis?

Everything you need is here: rd350lc.net/pageVIN.htm or here rd350lc.net/pageIDENTIFICATION.htm

So it could be:

a '86 RD350F2 model 1WW if 1WW - 000 101 ~ 002 000

a '86 RD350N2 model 1XA if 1WW - 002 101 ~ 004 000

a '88 RD350F2 model 3DJ1 if 1WW - 004 101 ~ 006 000

All are 50HP versions

Claimed 59hp

31w 50 again

Just pipes and carbs

so restricted in the stock pipes and exhaust? that's ok as I have F2 carbs or might go pwk28 and have the german race pipes to try..




do they ever make 59hp? reason I ask is mine made 57hp at muttsnuts and the guy in midlands, with a zeel and pwk28 with pod filters it is running allspeeds which I think its where its getting held back, but talking to a tuner, a 31k with a zeel and pipes around 60hp I would of thought around 53 stock, hopefully muttsnuts might fill us in on true figures

Realistically a stock one makes 45ish horse

59 was a crank reading

Allspeeds will restrict top end.

I'm sure the 1ww motors had 1ua barrels so you will be fine

My N1 made a reliable 51 BHP at the rear wheel on Gibsons dyno.
Totally standard, carefully assembled.

That's a good result.

I reckon on standard porting low 60's is the limit

Porting will get you to 70

Most I've seen on standard stroke but everything else done is 72

Certainly worth a couple of hundred quid on porting for 10 horse
