"Opinions on Big bore 920cc"


  

          

I picked up a basket case 850 E start. I think that I'm going to need pistons. I'm considering the 920cc big bore kit from RGM. (It's a standard bore now so I don't need to sleeve.)I'm looking for opinions from people who have done this. Was it worth it, as far as being a noticeable power improvement over an 850 (828)? Any regrets? I was going to go with a Megacycle 560-NSS and bump up the compresion a bit (9-1). Any thoughts will be appreciated.
Thanks, Tyrone

I haven't done this or have any first hand knowledge of anyone who has so I can't really comment.
If you do this, I would be most interested in your results.

Mike

Karl,

RGM website is

www.rgmmotors.co.uk

Also try Norvil, of course.

I had a 920 kit on my Mk1 850 some years ago, and it made a good bike better. I have a Mk3 now, and when it goes bang (but it won't, and I'm too miserly to do it until it does) it is also getting a 920 kit.

Maybe a bit less revvy, but even more of that lovely torque! Other than jetting, which is close anyway, no real changes are involved.

A bit of a diversion, but the old T160 Triumph Trident (the last ones, with electric start)was always meant to be an 850 not a 750, and as an 850 or 900 (both available today) it too is a transformed bike.

Hope this helps,

Ian
