They seem pretty good and I really should have done a dyno run before I fitted the carbs just to see what the 865 barrels turned out
They get bad press compared to the FCR flatslides which is a bit unfair IMO

One small niggle I'm having is when I "blip" the throttle to change down gear etc, I just get no response from the throttle
Don't know which part of carb to adjust to get a clean "blip" if you know what I mean ?

Thanks

The later style wheel has a different hub to accept "straight" spokes to stop the spokes breaking which was a problem with the earlier wheels which had a right angled spoke design where they were attached to the hub

Got some new tank badges , the "garden gate" or "mouth organ" style and removed rear pegs

The new badges are bigger though , so gained some weight !
