The Bultaco-manufactured polished aluminum triple clamps are the flat style utilized with Bultaco leading axle forks. The engine is located slightly lower in the frame as is the swing arm pivot.īultaco doesn’t publish the vital statistics of its front end geometry, but we measured the steering head angle at 29 deg. The idea is to stiffen the downtube assembly and prevent it from flexing if the owner 'should neglect to keep the motor mount bolts or the head steady tight.
There are pros and cons about the use of this type of material for motorcycle frames (some say it is more prone to cracking and is harder to weld for repair, besides being more costly) but it is generally regarded as being stronger and is lighter as well.Ĭhanges in the frame for 1977 include special gusseting around the steering head, patterned after factory GP equipment. Chrome-moly is what we've come to expect from Bultaco and chrome-moly is what we get. We’ll kick off with a look at the chassis. This is version 1977 and changes and improvements abound from one end of the machine to the other (about 284 according to Bultaco’s count). This is not a 1976 model with decals moved around on the tank. This is this year and we all know how fast things happen in the motocross world. Last year’s Pursang was good, but that was last year. Nowhere is there a better example of this than the 1977 model, which uses just about as much recent MX technology as one machine can.
It means a change can take place on the assembly line almost immediately, rather than 10,000 units down the road. And pretty turns to beautiful once the engine is fired and the bike begins circulating around a motocross track.īeing small has its rewards. The newest from Barcelona is one of the most amazing motocrossers we’ve ever tested.

Judging by the latest model Pursang, Bultaco can still show some of the big guys how to do it. In comparison to the Japanese giants, Bultaco is a tiny company, but a very efficient and formidable one. In fact, it would take blinders to keep most serious off-road riders from noticing a shiny new one in a dealer’s showroom or being transported down the road in the back of a pickup. Taco attracts a fair number of potential customers. The most important wire not to be snagged to earth is the black wire from points to connector block and on to coil.A Shining Example of What a Small Company Can Do When Faced With Stiff Competitionīultacos draw the eye of an onlooker through a smooth blend of attractive purposefulness, a touch of polished metal here, a dab of bright color there.
Yellow connects to other coil on base plate. Green to tightly wound coil on stator plate (next to condensor) red to other end of this coil. If wires from magneto have been changed black wire should connect to terminal on points (along with condensor). When depressed the cutout should earth this connection. If you want to connect a cut out switch run a wire to live (unearthed) side of switch from number 3 on connector block. Connect yellow to number 1 on the connector block, red to 2, black to 3 and green to 4.įrom 3 on connector block a black wire should run to HT coil live.įrom 4 on connector block a white wire should run and be earthed by a HT coil retaning screw. On the stator plate itself the wiring should be-įrom the flywheel magneto base plate there should be a green, black, red and yellow wires. Scrape paint from all earth connections and check with meter. Many people move the capacitor from the stator plate to under the fuel tank for ease of access. Just follow the ingition wires and ignore the lighting.
Hi - here is a wiring diagram for the Sherpa.
