The engine and wheels were silver. The bike has a five-speed transmission and a kickstarter. Given that it's hard to move back from unless you have a spare slide , and given that it adds another 'unknown' into the jetting equation, it's probably a mod that's better to pass on unless all else fails. Okay, it might be permissable to whack on a bit of throttle just the get the little bugger started before you start tuning, but it's a variable you want to eliminate. G ently turn the screw in until the idle starts to drop or miss a little, and note that position. You are making a difference to millions of riders worldwide. The fenders, side covers, frame, headlight cowl, and hand guards were white.
This manual covers specifications, diagnosis and testing, in vehicle repairs, component removal and installation. The convention is to measure pilot screw position in the number of turns out from fully-seated in , so note that. Despite expectations of 'precision tolerances' don't be surprised if finger pressure from the inlet side reveals a bit of play. That said, some people advocate a couple of more invasive solutions that you might like to know about. The fenders, frame, and handguards were white. If you've rounded off the cross-head screws trying to get them out, now is the time to replace them with Allen heads — M6x15mm. It is very detailed with good diagrams, photos and exploded views.
Later, Scott became a victim of his own publicity machine. Don't underestimate the probability of a blocked pilot screw hole — it can surface on a fresh, clean rebuilt carb purely on the grounds that it's the smallest hole any random bit of dirt can block. It's measured from the base of the carb body to the flat edge of the float in line with the main jet holder as the float tang touches not depresses the plunger on the float valve. Make sure your choke plate is fully choking air flow hit it with a file as necessary and not contributing to any cold starting problems. You can't really check this without the carb off the bike, but an easy intermediate 'solution' is to flush out the pilot screw hole using an aerosol with an extension tube you can slide up into the pilot screw opening — a can of electronics cleaner is ideal because you can really go to town and it'll evapourate eventually, wait a bit without leaving any residue. Do you think they knew that they had just built a wildly successful race bike as well as general purpose campground cruiser? Any obstruction here will give you starting issues, so make sure it's clean and flowing free. The seat was red but the fork boots and side cover panels were blue.
Autosol or similar chrome polish applied by hand will clean up the slide, and a few minutes on the slide barrel inside the carb with a Dremel-type tool and a small buff should polish out any imperfections. If you're lucky there'll be enough meat left to get them out with a pair of pliers. If you're checking float levels with the carb on the bike and you don't have a float gauge cutting a piece of stiff card into a 14. The transmission was a 5-speed. A good dousing with silicon spray doesn't hurt either.
The key to fault-finding and tuning is isolating issues and controlling variables. Now turn the screw back out until the idle starts to drop or miss, and note that position. Check the condition of the spring, diaphragm and O-ring install with the flat side towards the carb and ensure that all the orifices and passages are clear. Do you think that anyone at Honda knew? Make sure your fuel is good fresh, with no water or dirt , open the petcock and float bowl drain screw to make sure you're getting decent fuel flow clogged petcock, filter or even a blocked tank vent cap , and check for blockages in the overflow and breather tubes. This all goes wrong when the diaphragm develops a hole which, given the workout it gets in normal operation, is almost inevitable over time. The bike was manufactured by from 1985 to 2000, after which it was replaced by the liquid cooled model. The front fork featured a cartridge-type suspension.
The bike had a black, non-stainless 2-into-1 header pipe. If you've had a good result by this stage you can stop reading and start riding, but if you've still got starting and idle issues, there are a couple of things that might be behind them. Keihin uses a M4x13mm cross-head with a 7mm shank on the throttle spindle but it's a bit of an 'orphan' size and, since it's as much about clamping force as lateral play, an M4x12mm Allen head works fine. Double-checking the cables should be the first stop before you tear the carb apart. You can do it with the carb on the bike — loosen the clamps at the manifold and airbox so you can rotate the carb back and forth to give you sufficient clearance at various steps — but working with the cross-head screws is tricky especially when you come to button it all up again.
In a time when two-strokes were being hailed as the key to the future, Honda made a radical departure from the norm. A hi-performance power-up kit was available. How many motorcycles can you name that won Baja 1000 races spanning a 12-year period? Using different techniques and throttle openings to start the bike isn't going to help you get the jetting right. The bike was manufactured by from 1985 to 2000 and was part of the. He was a four-stroke man and made no apologies.
When he came upon lapped riders, they knew who was coming and would get out of the way. Together with the pilot screw it makes up the carburettor's slow-speed circuit. Make sure you get rid of any traces of polish residue. No, of course not—no more than anyone at Volkswagon knew what would happen to the Beetle. The best advice you'll ever get on jetting is to keep a diary.
The number plate panels were yellow. Scott was such a phenomenon that he changed the sport. . While you're there, it doesn't hurt to pull the main and slow jets and give the housings a squirt through open the throttle to give the needle jet some space when you do the main. You'll also want to make sure the float doesn't have any leaks and that there's no dirt or deposits stopping the float valve from sealing. Air leaks at the head and inlet manifold, carb and manifold, or even carb and air filter hose, will screw with your jetting. If you're too lean you need bigger jets more fuel , too rich and you need smaller jets less fuel.
It was a series that centered around one iconic race: the Blackwater 100. Eventually, however, you get some wear in the carb body and a few deposits on the slide that can add up to binding. That bike, first introduced in 1979, also proved to be a favorite of dirt riders everywhere and amassed racing victories all over the world and in a staggering variety of conditions. Other changes included an aluminum, rather than steel swingarm, a dry sump engine oiling system, and frame changes. All pages are in place and straight. While you're playing with cables, ensure the free play on the manual decompressor is set up correctly — nudging a valve open isn't going to help anything.
