dannybee Posted August 22, 2017 Report Share Posted August 22, 2017 Hi, Newbie here with a new to me Beta 250 and plenty of questions the bike looked fine when I bought it but looking over without the rose tinted glasses I think I've bought a dog ? 1- front brake works but feels crap hopefully clean the pads up and re bleed and it will good to go? 2- rear brake worked just about yesterday today nothing again I'll rebleed it and hope for best 3- The rear disc feels proper loose, It is tight and has spring washers on. Having read about replacing bobbins im hoping there missing or proper worn. Are the discs supposed to have a bit of play? 4- brake arm on the back is catching the chain slightly can't work out if I need to replace the arm or if it's one of the chain guides that's pulling the chain towards the arm? 5- Engine mount (top) was loose so I tightened it up and noticed it looks like it should have 2 parts so it bolts to both sides? Sorry for the essay bought the bike serviced and ready to ride from a buyer and seller on eBay , Even says brakes are crisp ! Not contacted the seller as I'm partly to blame for not checking the bike more. Lesson learned I like to tinker not new to messing with stuff so I'm gonna have to make the best of it !

2stroke4stroke Posted August 22, 2017 Report Share Posted August 22, 2017 Number 4. The chain runs very close to the rear brake pivot. Make sure the countersunk bolt is tight. Also fit the chain link with the spring link on the inside of the chain. 1 Quote Link to comment Share on other sites More sharing options...
dannybee Posted August 23, 2017 Author Report Share Posted August 23, 2017 (edited) Sorted number 2 rear brake, Had to strip master cylinder and clean all crap out of it as the piston was stuck up top but it's one job done and working well Edited August 23, 2017 by dannybee Added info Quote Link to comment Share on other sites More sharing options...
