    I used one as a communter for a couple of years. It was absolutely brilliant for the job, it never missed a beat in that time.

    I'd have another one myself, I wish I hadn't sold mine so damn cheap seeing what they go for these days!

    Hi

    A mate of mine had 2 of them, he bored one out to use a XR piston.
    Problem was he blew up both engines.
    Crank has no little end bearing and the conrod/piston pin area got hot and scored with that one.
    The second picked up on the middle cam bearing and stuffed the head somewhat.
    people are always looking for engine parts for these...could be a reason to look after it as these are nice cafe racers.

    My advice is don't modify them unless you don't mind spending cash
    and fixing it.

    Did they make a twin cam model?
    I know there is a 250 available (JDM though)

    Thanx Shadows, I've been tossing up between a GB and an SG350, my head says the Goose but my heart says the Honda, you guys may have tipped the balance towards the heart I think :-)

    This is commonly seen advice, dont you reckon they'd make an awesome race class though if you could find enough of them. Just imagine a squadron of them thud-ing their way round a track. Might start stocking up on old engines from the wreckers :-)

    BTW Bob, haven't seen you on the YB8 round Hamilton, is it reserved for special outings only? I was looking at the DB4 that NZVtwin had for sale in ChCh, finance etc fell through at the time unfortunately. Still keen on one, got any advice on issues to consider with one?

    I think with bikes you should always follow the heart, not the head. Get the goose and you'll always be thinking about the other woman. Any way, if everybody used their heads all of the time, few people would ride motorbikes at all.

    I think there is a GB race class somewhere. UK I think.

    I agree with that. I paid $4399 for one brand new in 1987 and sold it a coupleof years later for ~1800. it was the faired, single seat (basically unobtainable) model too.

    ah well...

    $700, good condition (4 years old).
    I was wondering why the guy that picked it up was smiling so much. He must have known something.

    The one DMNTD is selling at the moment for $2000 is single seat and has the fairing.

    My first one was purchased '97 single seat with fairing, 28000kms on clock. and a valve head fell in 5 days later. Superb chuckability and very forgiving if you stuff it up mid corner.
    Its now in the shed hence asking for ideas. the carb is sticks in the rain, I have overhauled it twice and still no idea! Any other ideas for the carb? Is there a better carb to bolt in?

    What is making the carb stick? i used to ride mine in tropical cyclones and left it parked outside for about 2 years without any problems

    Butterfly appeared fine.
    When I flood it with petrol(ie back flush) by putting hand over air intake and grab handful, this clears any blockage and is fine, until the next time.
