Japanese Bikes / Honda H100 saga need help with carb jet adjustment
« on: July 08, 2017, 11:20:57 AM »
Hi all,

What a quite forum this is ! I am gradually making progress with my H100. It now runs of sorts. I have no air filter and can't source one locally but the main problem is once I get the engine running I need huge amounts of throttle to keep it running and after about a minute it dies regardless of what setting I put on the idle or main jet adjustment screws.( Main jet  I think is the   screw near the orifice of the carb and the idle has a spring behind it. I started with about 1 1/4 turns on the main jet and 2 1/2 turns on the idle screw).
I have cleaned the carb .

Sorry Rex still no manual :-[

All suggestions gratefully accepted

Japanese Bikes / Honda H100 saga. No spark
« on: June 11, 2017, 12:08:46 PM »
Hi,
My Honda H100 2 stroke  has no spark or very little. I bought a flywheel puller only to find there are no points!
I have removed the HT coil and checked it by flashing 6volts to the LT terminal nil or very poor spark.

The HT lead seems OK
Not sure about the plug or the plug cap.
even putting the lead next to earth does not get a spark.

Measuring the LT circuit with a multi meter I get a very low ohms reading on any scale but do get continuity.
The HT circuit I get a reading of 4k Ohms.
The bike at the moment does not have a battery but I have been turning the ignition on. I think the ignition is independent of the battery.

Any ideas?
Many thanks

Japanese Bikes / frozen throttle slide
« on: May 10, 2017, 11:54:02 AM »
Hi ,
From my last post. I am cleaning the fuel system of my Honda H100. two stroke. The throttle slide has frozen in the carb Body.
I have tried WD40, slightly heating the body of the carb ( I have to be careful or I will melt the top plastic screw cap!) Tapping the slide with a wooden dolly using a hammer and tapping the body of the carb. also Levering the slide with a screw driver  (carefully).

I have run out of ideas. any help would be much appreciated. The bike has not been used since 1990.

Japanese Bikes / H 100 Fuel tap replacement
« on: April 30, 2017, 10:26:00 AM »
Hi ,
I have a Honda H100 1984 ish! I have found that the fuel tap is blocked , I expect it is the internal seals that have perished.
The assembly is riveted together so without destroying the tap I am stuck. My local Honda dealer wants £ 56 if they had one in stock!
I can get one from China for £6 odd but I am not sure of the thread. It is 14mm dia. The Chinese thread is 14mm x 0.1 pitch which seems to be pretty standard.
I would really prefer to get a tap from the UK if the price was right.
The part number is IAOI-5056580

Or maybe a tap from another bike would fit?


All advise would be most welcomed.

Japanese Bikes / Honda 100
« on: March 29, 2017, 11:15:44 AM »
hi ,
I have a Honda 100 two stroke  in relatively good condition that has been sitting in my garage for the last 28 odd years.
 It is "X" reg ( 1981?)

The millage is 15000. It will need new tyres and battery. My question is :- Is it worth spending the money on  tyres and battery MOT etc or should I just sell it "as is"  . I appreciate it is not worth a lot but it would make a good run around.

Many thanks
Richard
