1980 Honda H100A from United Kingdom - Comments

6th Jun 2006, 11:51

I had an H100 as a lad and loved it. I am now restoring an H100a, and after starting this project, I found out that the little bike was only made between 1980 and 1983, so after twenty odd years they are a bit rare.

Good old bikes, so get one while you can, and watch the values go up in a few years. But most of all, have some fun on the old girl.

I am the narrator of the above review, and would like to thank you for your interest. As I mentioned the plan of restoring the H100A that I bought back in July of 2003, I can glady say the restoration is now near completion. She looks great!

Just like walking into a Honda show room back in 1980. I could never part with her, and good luck with your restoration.

These little bikes deserve to be preserved.

I also have a second H100A (late W plate 07/07/81) that I did restore, shortly after buying the first one. Unfortunately, I need a petrol tank for it that I can`t get hold of. Otherwise mechanically, she is sound.

I have found that a lot of people, especially the Used Bike Guide (and me previously) don`t rate the H100A that much. They should live with one for a year, and they will soon love it, as much as I did.

With regards to the above comment. Do you think these little old bikes will soon start to increase in value? I hope so.

This is indeed a great wee bike to start you off in the world of motorcycling. It is also very good bike to start learning how to maintain and work on, as there really is nothing complicated about this bike.

I bought one 5 years ago with the intention of it being an easy project to get onto the road.

Rebuilding the top end is pretty easy, with a little patience this can be done in as little as an hour. Top end comes off after removing 4 head bolts and the bolt holding the head to the frame. After that it's easy street.

So far I have rebuilt the top end, replaced the ignition system, had the rear wheel rebuilt, fitted a new exhaust down-pipe, made up front indicator brackets, replaced the speedo, fitted a new chain and sprockets, rebuilt the carb, changed the fork seals and fixed the speedo drive gear in the front wheel hub.

This bike was obviously designed with the home mechanic in mind as there is not much that you can't do yourself (except dismantle the bottom end of the engine, which will require special tools or expert knowhow to split the crank half's).

And for such a small bike, they handle very well.

I'm amazed that someone has managed 98 out of this wee bike, I would have thought the engine would have blown up!!!

Hiya.

I have just got a H100 1984 to learn to ride on and the speedo works, but the rpm doesn't. Any ideas how I can sort this problem, or where I can buy a whole new speedo from?

Please reply, many thanks.

If your tachometer (RPM) doesn't work, firstly check the cable as this is often the cause. Do this by unscrewing the knurled retaining nut at either end and pull the cable. If it is broke, it will soon be obvious. If you are able to remove the whole cable, then the fault is elsewhere.

With the cable removed at the rev counter end, start the engine and if the cable rotates, then the fault maybe the tachometer. If the cable remains still, then check the drive gear by removing the clutch cover. Carefully examine all other possible causes before resorting to a new tachometer unit, as this unit may be hard to find second hand and a new replacement is quite expensive, if available.

If you need any parts, try Davidsilverspares.co.uk. They are really good and deal specifically with genuine and pattern Honda parts. If you use the web site, the bike you have is the H100S and not the H100A.

Thanks for your help.

I passed my CBT a few days ago, and went for my first ride, and noticed when you reach 20 mph, the speedo pin starts to jump around between 20 - 25 mph, Is this OK because it's a bit worrying when I go through speed cameras; I look at the speedo and see it jumping around and think to myself am I over or under the speed limit? I just tend to cross my fingers and hope I'm under or at the speed limit.

Any help would be much appreciated.

Many thanks.

Hi again.

I've got another question.

Can H100s have a sidestand because I would rather use a sidestand instead of the centre one.

Thanks, Jamie.

Hi H100 dudes. I've just bought one, they are cool. Mine's been restored so I'm a bit of a a cheat. I have had to get new keys and battery, but other than that it's fine.

Could I be cheeky and ask a question. I've got a new battery but no charger, can I put it on the bike, jump start the bike then go for a bike ride to charge it?

I am the narrator of the review and can gladly say the 1980 H100A is fully restored. It needs to be run in for about 500 miles, but I have been working it too hard and it cut out on me the other day. Lucky the engine didn't seize, it just over heated. The old girl looks great in light blue with new chrome. I honestly never thought these little machines would be so popular.

I have spent about eight hundred pounds on the restoration, but the list is rather extensive. One would argue I could buy a brand new Chinese bike for about seven hundred, but quite frankly these are of very poor quality and only last about three years, so therefore I wouldn't bother.

With answer to your question, these little bikes will run without a battery, but I don't recommend it, as it is possible to destroy the regulator/rectifier on some machines. It is instructed in the literature supplied with new batteries that a trickle charge is necessary before installation. I do this with all new batteries. However, one time I didn't and the battery had to be renewed as it became defected. So I would recommend a trickle charge with all new batteries.

Hi all, I just bought an H100a on an X plate. It cost me £225 with almost 1 year's MOT, and I thought it was a good price for it as it's only done 19000 miles. I guess this is genuine as I can't imagine them being clocked these days..

The only fault mine has that the person who sold it to me couldn't get it to run off choke, but after looking at it the other day, I found the air mixture screw was turned right in, so no air was getting through on tick over. I ran it for about 45 minutes off choke and it seemed better, however it sometimes over revved so I switched it off!

However, when I tried to start it the next day, it ran but seemed very lumpy on tick over, so I guess I'll have to look at it a bit more, but other than that, the bike seems in good order and it looks in good condition with no real rust, only minor spots.
