Bigger engine
 

Hi guys,

I was wondering what's the biggest / best /most reliable D2 engine that I can fit to my Sorn'd 600 carby Monster (not the DD bike, the other one).

I love the 600 but being able to enjoy it on the track with the DD bike, I find it slightly boring on the road.

I'm looking for an engine that would fit without too much hassle too.

Cheers,

Froggy.

Tonio,

I think that you will find that a 900 will go straight in, but not certain about the exhaust system, 75bhp should make it quite interesting.

Hi Tonio
As Chris says a 900 will go in without any problems, and the exhausts are the same size. and also the carbs and Ignitors can be used

I have just fitted the last of the Carb'd 750 engines into a 600 Monster, but for this conversion I had to drill out two engine mounting holes from 10mm to 12mm and then I tapped the holes on the opposite side to M12 X 1.25mm

No reason a 900 or 750 injection engine and running gear couldn't be used, or even a later 800 or 1000 but expect to pay a bit for the running gear as clocks and ECUs are coded on these later bikes.

I may have a 900 engine and a 750SSie engine and running gear for sale in the not to distant future

Cheers guys. I reckon 900 will be the way to go.

Kev, I might well be interested in your 900 engine if and when you part with it. Would you me ltting me know in case I miss your ad for it?

Is there any difference between injected and carbed 900 engines or just the fuel intake changed?

probably a difference in the flywheel and ignition pickup but its not something I have looked into, also the issue of single and 3-phase alternators and associated Rectifier/regulator

Something like this antoine ?

(are you running in the knacker-cracker by the way ?)

Hi Phil,

Yes, this is exactly what I want to build. I love Cafe Racers and the Monster must be a good base for one.

Unfortunately no, it's not this year again that I will try that race. However I will be on the start line for the Leith Hill half. Are you running it again next year? It's on the 7th of March.

You're not doing the MABACs are you? I'll will be doing the one in Wisley on Sunday.

I certainly will be doing the Leith Hill Half ! Its one of the best hill runs around here.
I'm running a 9 miler near worthing on sunday - my first race for 4 months cos of achilles tendonosis.
Then its the Cracker possibly followed by the G3 races as training for Leith Hill, unless you can recommend some other 10-20k races ?

If you fit a 900 lump you'll develop a silly grin you know ;)

Are you sure about the exhaust sizes? I know the 600 and 750 downpipes are the same part number (at least on the SS), but they look awfully restrictive for a 900.
