Re: oil return hoses

Thanks for the description of internal processes of a 4 stroke engine...."And we also know that by creating a vacuum, however slight, we should be able to see less oil leakage from the seals, kickstart shaft, shift shaft, compression release shaft, and the gaskets." ...in my case this is certainly t...

Re: oil return hoses

i have seen mentioned a larger diameter exit hole on the primary chain case helps with breathing. I had this chain case from a tr****h 250? lying around and what do you know they had conveniently placed the filler cap on the top allowing for a suitably threaded spigot to be attached. Of course an at...

Re: oil return hoses

Tom
is that an unvented oil filler cap i can see in your picture? A vented one is specified in the parts book. Does this vented cap have any bearing on pressures?

Re: oil return hoses

Tom i tried the water bucket at the exit of the breather pipe as you suggested....i seem to have had the same results as minetymenace described, i.e some bubbles at start up then nought. i did the test after riding when the bike had had a hours rest. Today was a little cold but i took the b50 up one...

Re: oil return hoses

well i have fitted the Y*maha reed valve and the engine has thanked me for it. No leaks at all from anywhere (yet) but only clocked 35 miles. Operating temperature has dropped several degrees, Celsius. Carb retuned to drop idle speed to about 650rpm from 1000rpm + .Valve cost : $35.00 Increased perf...

oil return hoses

Its spring over here and i am prepping the b50 for the new season. I have been reading the tech pages avidly re the crankcase breathing issues etc. I have a 650 yammy reed valve to fit and hope for a drop in oil leakage. Now my question concerns the reconfiguring of the oil feed lines esp. the fitti...

Re: Shifting into third issues

When the detent spring breaks you usually can change gears quite readily, however it will not stay in gear which is one of the functions of the detent. I would be very surprised if the problem isn't a broken spring. Mine had broken at just the right position for the sharp broken end of the spring t...

Re: Shifting into third issues

I had this exact same problem when i first bought my b50. A retaining spring inside the gearbox interacts with the the cam plate via notches to prevent jumping out of gear. Mine had snapped. Yours will have too.

Ok, then how is early and late defined? mine is october '71 and has a up lever. Is that early? I am certainly finding the tech details that are emerging on the brake lever very interesting.
