My bike: kick start rebuild

 Ouch... I routinely roll the MBX out the garage, fuel tap on, choke on, foot peg up and prod the kickstarter and snap, the kick start shaft snaps clean against the crank case and takes a little bit of leg with it.

Looking at the owners manual its not a massive job and the kick start shaft can be replaced with the engine in. Also in the owners manual it states that there are service limits not only on the shaft (6) but also the idler gear (2), inspection on the oil pump gear (1) and both kick start springs (8 and 5), so I decided to replace the lot including the collar (9), ratchet (4) and ratchet gear (3).

For availability all parts were bought via David Silver Spares and CMSNL

On to the repair...

First drain both the coolant and gearbox oil. Tip, remove the rad filler cap!

Remove the rev counter cable and clutch cable and remove the right hand side cover. Tip: pay attention to the clutch actuator pusher on the inside of the case!

To just do the kick start shaft you don't have to remove the clutch, but as I needed to replace all the gears the clutch had to come off. NOTE: If you do take the clutch off the balancer shaft does need to be timed to the primery - see bottom of the page!

plastic oil pump gear, check for wear and tear.

To re-fit the new idler gear you will have to remove the ratchet plate 

Refitting the kick start shaft and getting the spring tension can be testing... 

Don't scrimp and fit a new gasket

Ratchet assembly, next is to get the correct clocking and spring tension. 

here is the clocking and alignment from the manual.

FWD-F: Twin disc UK 2nd gen model

I while back I had a conversation on our facebook page with an ex-owner who said he had a MK 2 MBX80 (rainbow) bike that was UK specification complete with twin discs. At the time I thought this was super interesting as I knew Honda only brought in the original MK 1 model in black and white for a couple of years, so what could this MK2 be?

The guy mentioned the dealer, Rustys in Scunthorpe and they just so happened to be a customer of mine so I reached out to them to see if they remembered selling the bike, keep in mind this would be 35 years ago. They mentioned they remember selling little Honda's but couldn't pin down any specifics, so I just chalked it down as interesting but without a bike I just had to take the guys word for it.

Fast forward to 2020 and I was contacted by a chap called Mark Roberts who had a UK MK2 bike. Better still the history of the bike is complete, first registered in 1986 on a D plate it was bought from The Honda Centre in Old Colwyn North Wales (now Colwyn Bay Motorcycles). Mark bought the bike in 89, subsequently sold it to a family member then bought it back it now stored and waiting for a light restoration. Apparently there were a few bikes kicking round North Wales which leads me to believe Honda imported a few bikes in 86 for a few specific dealers (like Rustys) who saw there was a demand for the bike but never included it in the official range.

What ever the full story was from Honda we may never know as Honda never nationally promoted the model and it didn't appear in any literature, but seeing some genuine UK MK 2 bikes makes for an interesting foot note in the models history.

Thank you to Mark Roberts for helping fill the gaps in this story and sharing your bike!

According to the parts listing on CMSNL this model is designated FWD-F and as a 1985 model, view the spare parts here:

How Many Left? MBX80 FWDD

According to the website 'How many left', there are 24 MBX80 FWDD's left in the UK, as of today just 7 are currently taxed and 17 are on SORN.

With this in mind I would like to open a register for all remaining FWDD's so we can catalogue all remaining bikes and what condition they are currently on.

If you have one of these bikes (specifically the UK FWDD please) please e-mail me a current photo of your bike and its registration for inclusion on the MBX80 register page. Please also state if you would prefer not to make your registration public and I will withhold it.

My top 10 tips for completing a restoration.

My top 10 tips for completing a restoration.

1/ Have in your mind a clear vision of what you want to do, be it a show bike or tidy run around a clear vision of what you want to achieve will impact each decision you make.

2/ Join a club or group for the model you are restoring. You will see similar machines, get tips and advice and also make some new friends!

3/ Ebay is a great place to search for parts (also try different countries ebay sites), but also look at where the bike was popular and look for shops in that country as spares will be more plentiful in countries that sold lots of bikes.

4/ If you are going for a factory style restoration, all bikes will need lots of work so a £400 nail really has the same worth as a £900 runner as they will both need similar amounts of money spending on them.

5/ Strip the bike down in groups of parts or sub assembly’s and store all the appropriate parts in storage boxes. 

6/ Do all the power coating or zinc plating in one batch. Many painters or platers will have a minimum charge or batch price, so if you forget something like a side stand you will need to make minimum charge again to get it painted.

7/ Get the frame powder coated ASAP, once this is done you are always in the re-build process and physiologically this is good!

8/ Always do a dry assembly or test assembly before mounting a component properly, there is nothing worse than fighting to fit something with greasy bolts that won’t line up or getting a cable routed the wrong side of something.

9/ Take lots of pictures, buy all the owner’s manuals, workshop manuals and parts books you can find so you can double and triple check cable routing and decal placements.

10/ If you feel a job is to big, don't be afraid to ask for help or employ an expert!

The last thing, so technically number 11 is just to have fun and enjoy doing it!

Owners bike: Patrick Mees, red MBX80

This owners bike comes from Patrick Mees, whom like myself owned a MBX80 35 years ago so jumped at the chance to own another. The new bike has just had a full engine re-build and is ready to enjoy!

Did you own a MBX in the 80's and have you got one now, please get in touch and share your story!

MBX50, the creature from the black lagoon!

So... I seem to have acquired a MBX50, she is not pretty and she has missing wheels, but she was very cheap. In fact I have seen this bike before as a friend showed me it for sale on facebook and I remember commenting that I think its been stored at the bottom of the sea...

What we have here is a bike with a V5, some brand new gaskets and piston and a complete spare frame. To be honest my plan was just to sell the usable parts, maybe keep the engine to make a cross section for future shows and bin the rest, certinally the second frame is so rusted it is fit for the skip. But there is also part of me that thinks because of the V5 is it possible to save? Sure it will take a bit of cash to resurrect, but that depends on the final finish you want to achieve and of course finding a set of wheels.

So the question is, do I break it or save it?

rusty spare frame, this won't polish out!

My bike restoration update, almost there....

Some new detailed pics of my MBX80, I have a couple of things I want to change but these are mainly the colour/ finish of specific bolts.
