650 race bike, 4 speed with late high gear. I've had 2 aftermarket trap doors with a bearing to try to control mainshaft deflection and both were too "thick".
I have found a shielded ball bearing that will fit both the stock trap door and the mainshaft. Been using it this season and it has worked ok but I remove it after each race weekend to check it , remove the shields, clean and re grease. But it is only 1/4" deep and it seems it could be pretty fragile.
So, what have I gotten for the aftermarket doors? Maybe BSA? Do A65's have more room behind the clutch basket?
And what has anyone done for Triumphs? I know others have done bearings there, how and what has been used to get more support there?
Thanks, Mike

I'm not usually the guy who adds complexity to a project unless it needs help. In all the years of riding triumphs, I never saw the need for an outrigger until I started racing. Probably the combination of making decent power, sticky tires, frame flex, etc., I saw the sprocket/ chain gouging the insides of the cases. That indicated to me that something in there was moving. For my other bikes, I don't see any need.
Got it, Kommando, thanks

...I had and aftermarket door with the bearing in one of the T140E. I had some oil slippage there; then RPM (big D cycle) commented that he never used one in any of the racers so I removed the aftermarket and installed a new OEM with the seal.
