Bevel twin question

Colin,

I’m pleased to say that I now have a clean running 750. Those 3 piece oil rings really do seem like o have made a huge difference. Compression readings are much the same as previous but no more oily running.

Hi Ian,

After I had my 750 rebored I could never get the engine to run clean - the piston crowns were always oily. After some years I rebored the barrels again and fitted Vee Two pistons that had those three piece oil rings and I followed the fitting instructions of assembling them with WD 40 and not oil, and from then on the piston crowns ran clean and dry and the engine ran noticeably better.

Cheers,

Colin

Hi Ian,

That's good to know; hopefully as the rings bed-in the engine will get better and better. I don't know if technically the three ring oil scraper has an advantage (maybe Nigel or Eldert can comment) but they work better for me.

I keep casting envious eyes over 750 GT's for sale, but know it would be folly to take one on now I am in my 70's. I doubt that I am strong enough to lift the engine up on to the bench!

Cheers,

Colin

Hi Colin, This old age thing is 'cr*p'! When I bought my 350 mk3 new in 1974 from a motorcycle dealer in Belfast they also had a new 750 GT sitting in the sunshine outside the shop....unfortunately I just couldn't scrape together the extra (I think) £160 to buy it so just got the 350. I have looked at maybe buying a 750 off and on for years and as the prices just got higher and higher I couldn't justify it, now prices are most definitely on the way down and I could easily afford to buy one (if the right one became available) however now I believe I am too bloody old in my 70s to actually properly enjoy one .......ah well......
Cheers George

Hi George,

Yes, 750 Ducatis are my all-time favourite bikes and I wish that I still had my 750 Sport. I dream about getting a 750 GT, and there would be no problem riding it, or wheeling it out of the garage, because they are so light, but I cannot justify it because I don't go anywhere now, which is the reason why I recently sold my GT1000 Sport Classic and my 900S2; they were sitting in the garage without being used. Most of my riding is along country lanes between 40 - 60 MPH, and my 250 and 350 handle that, not to mention the Enfield 350, which is adequate for the rare occasion when I go further afield. If I find that I need a bigger bike, a 650 Enfield would be all that I need, but motorcycles are not bought with the head, but the heart, and I want a 750 GT....

Cheers,

Colin
