my next project is going to be a NC23/600

Does anyone know which year 600 engine I need that bolts into the 400 frame ( yes I know the frame spars need welding)

well apparently it the F1 and F2 engine.

So other than the following what do you think I will from the donor 600?

Loom and all ancilleries
Clocks
Engine
carbs
Airbox
Exhaust?

does an 893 blade not go in with a similar amount of hassle?

thinking aloud...

Hybrids are cool

A short while back there was a member (Shane) gave an account of his 4/900 in the forum, its gone now but luckily he gave me permission to copy his post. Find it on my site here. https://sites.google.com/site/cbr400rrr ... oject-4-90

It might give an insight.

nice one I'll have a look

opps I just remembered its 23 your after. I do think i have a mag that mentions a 900/nc23 conversion I will look it up.

thats its a 600 lump I'm wanting to put in though.

Shame that thread you linked doesnt give much info around what cutting was needed.

Yes I know, I suppose he never thought about it at the time. Anyhow I have found the article but it is a 900 engine in a 23, a couple of decent photos uncovered and a bit of info. The article is from November 1996 Performance Bikes called "SwitchBlade". If no one can get it fast I can scan it a bit later if you want.

I suppose my original post was in answer to CMSMJ1s post mentioning the 900 motor got me started and do realise you want a 600 motor in. But everything helps I think..
