Hi All
I have had my Beta for about three weeks now and am loving every moment. I have a off-road history, but the trials fascination was finally getting too much.
I have gone through the bike systematically and have a wishlist of parts I am waiting on. Trials is very rare in South Africa and spares is a big headache.
I have sourced a second hand air box as mine was pretty abused in its life. I am waiting for new carb rubbers as well as the front manifold is showing cracks.
The issue I require help with is 'airleak' that seems to become more noticeable if I ride for +/- an hour. The revs then almost don't drop at all. The carb has been cleaned and the bike runs fine for the first while. I have to ride +/- 3km to my playground, so the bike warms up reasonably quick. I don't loose any oil, so I suspect the flywheel side seal is gone.
Do I need to split the motor to replace it? Any idea why the bike gets worse after the hour period - I do have rest breaks in between?
Cheers
