Question

Could you tell me how to get the speedometer seals (one rubber 1 metal) out of the bottom of my engine? Mine is leaking ... Do I use a icepick or some other sharp instrument? I have the new seals. They say I can.. but I am concerned that I could damage the case...The bike is a real nice Matador MK2. I used to own one when I was only 19.. Now I have another one at 51... Greta Bike but I can't have that slow leak...Thanks for any info...
We contacted Cody Tellis at Bultaco West to get you an answer. Here is what Cody said:        On the Matador...there is a small set screw on the side of the hole for the speedo gear at the bottom of the cases. Pull the set screw, grab the gear (Bike is in Neutral) and pull until it comes free. Then replace the seals (O ring type) and reinsert...If you move the bike they are bear to get back in so be forewarned. Oh...forgot to mention the obvious.. on the speedo there is 3 screws on the face plate..these too come out to remove the gear.

Question

How do I make my 104,120,167,192,193 brakes work better.
We asked Chuck Akin in Costa Rico to help answer your question. Here is Chuck's answer Bultaco brakes? what brakes? If he wants brakes that work, buy a Yamaha. I use what the factory boys used...Longer (4") brake arms (Unfortunately, I can't tell you what Bultaco they are from) Take all the the bends out of the rear brake rods and dump the original front cable. It stretches badly. I make my own by shortening a Yamaha cable. (It has larger wire and is Teflon lined) but you have to drill and tap the boss of the brake stay arm to 8mm to accept the adjuster. Also clean them regularly and always after they get wet. Something about the shoes (OEM) seem to absorb water and they're never right if they are not dried out quickly and thoroughly. (I never use the words "water" or "Agua" when I'm within 20 feet of my Bultaco.

To do the cable Chuck supplied the following: A 77-84 YZ, WR or DT cable should work. Any brake cable with an 8mm threaded adjuster on the bottom and the right size cable ends should work. That said, it will need to be shortened. (The Yamaha brakes are on the left side of the hub but the Bultacos are on the right and obviosuly the fork travel is different too) On a Bultaco, the boss is on the brake stay arm. The boss has 6mm threads and needs to be drilled and threaded to 8mm. If you start by rethreading the Bultaco boss and then installing the bottom of the cable, (ie thread the adjuster all the way in and hook the cable end into the brake arm) it will be clear what you need to do with the other end. If you use the 4" brake arm you will need more wire length than if you use the short stock unit. Use silver solder to replace the cable end(s) Standard solder is too soft and the wire will pull out if you are a serious front brake used. (Learned that twice the hard way)
