Sounds like the jets are clogged in the carburetor. Try running some carburetor cleaner through it first. If that doesn't help then you will need to have the carburetor rebuilt. Hope this helps. Good luck.

    I have had several of these bikes and right now i have 3 of them, all of them do this when they are cold they are a very cold natured bike, but assuming that this problem accures when it is hot you should check the carburator and make sure the main jet is clean, while you are in the carberator adjust the float level as this could be the problem also, the next thing i would check is the screen in the petcock bowl it seems that your bike is starving for fuel and the last thing that i would do is adjust the carburator, they are not adjusted like a normal one, you have to raise the idle screw to 1200 RPM then adjust the idle mixture for the max RPM keep adjusting the idle speed screw to keep it at 1200 RPM. when you cant get any highter RPM from adjusting the idle mixture than you are done. This will get rid of that dead spot.

Hi, Anonymous and the usual suspects are:
1. Throttle cables misaligned or misrouted.
2. Damaged or restricted fuel tank venting system.
3. Intake system air leak.
4. Vacuum piston malfunction.

6. Plugged bowl vent or overflow.
7. Fuel level in bowl too low.
8. Restricted fuel supply passages.
9. Plugged jets or passages.
10. Worn or damaged needle or needle jet.
11. The enrichner valve not seated or leaking.

After lots of work my 1972 Honda CL100 scrambler is up and running, however, I'm not convinced it's running to it's fullest capacity. Here's what I'm experiencing; at the high RPM end...


They are not a rocket ship, but I would expect closer to 50mph .
need good air filter element.
ignition advance springs can cause a problem, or the advance may be sticking.
need good battery, recheck point gap, timing and valve clearance.
check for exhaust blockage(see if it revs better without the muffler)

You have probably tried most of these, but there is not much else, they should rev sweetly right though the rev range

96 Jimmy bogs down when I accelerate hard


Sounds like the fuel filter is getting clogged. It will flow enough fuel for normal driving, but can't supply fuel for full throttle acceleration, causing the engine to bog down. Replacing the fuel filter with a new one should fix the problem.

What's the best way to change handle grips on a 1972 honda ct90


assuming you have bought yourself a pair of rubber grips, with a sharp knife cut through the grip to remove it clean away any old glue, replenish glue onto grip and handle bar and simply push back on to handle bar quickly clean away any unwanted glue, remember to check you new grips for internal diamiter these will be different sizes, with smallest bore grip going on the left handlebar, and the larger on the throttle twist grip, if you have bought honda original parts then the twistgrip side may be a complete unit , in which case you would need to undo the 2 screws that hold the rhand switch gear together, and twist the grip in the opposit direction to what you would do when you ride it to remove it from the bendix throttle system, replace in opposite manner using a small amount of grease inside the metal sleve,

Need Advice On Best Tires for 1972 Honda CL100


Brand is not really important. Just go to any motorcycle shop and tell them you want road tires for city streets. They may have two or three tires to choose from. Pick what looks good and go with it.

I believe your bike takes a 250 x 18 tire size on the front and a 3.00 x 17 on the rear. Look at the sizing on the sidewall of the old tires.
