Beta Rev3... Newbie Needs Advice

[greggo]

Hi everyone,

I have just purchased a 2001 Rev3 that has had some running time, but has done a bit of standing still in someone's shed.

Anyway, firstly i cant seem to keep any pressure in the front brake, even after hours of bleeding and taking the caliper apart, although i still cant see any leaks....

Secondly, the bike seems to run out of steam in all the gears after about 1/4 to 1/2 throttle. The engine doesn't die, but it feels like its hitting a rev limiter on a sports bike!!

As I've said, i'm completely new to these types of bike, so any advice would be greatly appreciated.

Thanks!!!

Gday, search for brake bleeding threads, there are heaps. Check your plug, it should be a coffee colour on the centre electrode. If its black, check your air filter and clean and re-oil it. Not too much oil. Try it again and see how it goes.

Cheers,

Stork.

First .... Your needle could be loose on the carb slide.

or.....Your timing/flywheel key may have sheared. Your reeds may be broken.

Or.... i'm wrong and don't know.

Yep could be a lot of things. First thing I'd do on a bike that has been "standing still in someone's shed" for a long time would be to assume the carb is gummed up. I'd pull the carb and make sure all the circuits are clean. If the owner says it was running fine before parking I'd say there is your problem. If he left gas in it that stuff turns to varnish after a few weeks or months. That's easy to clean out and something you should do anyway to be sure. I'd also start with a new plug and make sure it's the right heat range. I've got a 2003 250 and it runs good with a NGK BP7ES. Lampkins recommends a BP5ES and I'm not sure why. Maybe it's the fuel over there. I tried one it's too hot and I and get a lot of pre-detonation, but I'm not running race gas.

Finally, dump all the old gas if you haven't already and put in new fuel mix, clean the carb, replace the plug, give it another go. Good luck.
