Roper Plate Redux

Recommended Posts

Sport-I's use the 'Broad sump' the same as the V11. The thing is because of the taller gearing in the lower gears in the old five speed box the issue of oil surge and pick-up exposure doesn't seem to trouble them. This isn't to say it couldn't happen, just that I've never heard of a Sport-I running its big ends due to pick up exposure, (Or a Centy or Daytona RS.). That being the case, while fitting one is extra insurance it probably isn't necessary.

 

The carb Sports still used the old 'Deep Sump' with bottom feeding pick up so exposure isn't an issue.

Bravo!

Now one question... Will these fit, and are they a good idea for Sport 1100s? 

I'm laughing because I have a '97 Sport-i myself, and haven't yet confirmed that fitment. I think Pete confirms it elsewhere.

Since learning about the oil problem in V11's, I've tried hard to get mine to show ('97 Sport-i) by working it with  hard first gear climbs on a fairly steep hill- and I've not been able to see a flicker. All the same, I wanted one because that's just how we roll. ;)
