    i cant beleive i havent done this thread before now!
    as most will know, im quite a gifted mechanic and im battling bad health and had to quit my job.
    ive started doing my own stuff amongst which is bringing cubs to norway.
    they were never sold here, strange huh?!
    anyway i wont bore you with too many details.
    heres how i got it.
    standard chinese 110cc cub
    it is the first new one in norway and one of only 4 cubs...

    after a nightmare of paperwork and lots of tax i got it on the road.
    I ran it in and did a whole load of riding, both on and off road.
    its a test bike from the manufacturer you see, so i had to try and give it 2-3 years of riding in a few weeks to make sure i was happy with the build quality.
    it wasnt bad, just surface rust (i rode it through snow, mud, water and ice!)

    _2272807.JPG _2272807.JPG _2272809.JPG _2272812.JPG _2272816.JPG _2272822.JPG _2272829.JPG _2272832.JPG _2272833.JPG _2272835.JPG _2272836.JPG

    anyway, the supplier will amend these areas on my next order, the chrome will be powder coated black and the nuts and bolts will be zinc coated anodized or something.
    so after doing a few services and stripping the whole engine to check how it was running, i decided it was time to do a custom build.
    Its a very long a complicated process here with documentation needed for everything. more about that in my next post.
    essentially i will build something a bit fast, but also a bit flashy, an attention grabbing bike.
    i have already fitted a 140cc engine which goes like the clappers, but i feel i can make it a little better.
    i also NEED to upgrade the brakes, i will go along the conventional forks route, then i can use a disk brake. im looking out for a cheap pitbike in my area to borrow parts from....

    heres a sneak peek at the next update:

    so anyway, i deccided to go along the custom route, i ordered a load of parts and they came after a LONG time.
    WP_20160805_12_17_05_Pro.jpg
    but it wasnt plain sailing.
    there was a little damage and the airfilter didnt really fit..

    WP_20160805_12_47_16_Pro.jpg WP_20160805_12_51_01_Pro.jpg WP_20160805_12_51_33_Pro.jpg

    but that wasnt so much of a problem. all easily fixed.
    the engine was quite easy to fit, but again, i came into problems

    WP_20160805_15_24_42_Pro.jpg
    the engine bolted right up into the frame, but other things where the issue, like the clutch cable and the carb manifold:
    WP_20160805_15_24_56_Pro.jpg WP_20160805_15_25_08_Pro.jpg WP_20160805_15_25_53_Pro.jpg

    so being a clever bastard, i made an adapter plate for the carb and got the grinder on the engine bolt to make the cable clear:

    thats enough for now, will updade more later or tomorrow...

    Head turner ...........

    honda cub CT 50 trail , ( guess the ct stands for cub trail ) it loose the standard front forks with those covers and is given a set of standard forks, with some knobleys installed and fairings removed. they look kinda cute i think and would 100% turn heads , if you could in some way fab a new exhaust pipe run and have it top frame mounted to keep it away from the dirt and ground ( can end) and just shove a load can on the end for the brap brap noise ;).... added a picture upload for inspiration :)

    and to make sure it turns heads, BRIGHT PINK bro lol

    i was thinking along the lines of the trial 90, there are off the shelf exhausts that are that shape (pit bike ones) i need an E marked exhaust though as the build rules here are so strict.

    i wondered, the CT90 looks like it runs the same C90 pipe end its just had the bracket moved more forwards. wonder if the same could be done to the stock c90 pipe end that way its a fully legal E marked pipe and should pass all your tests.

    one thing would be the exhaust shrouding, possible nuts welded onto the exhaust to accomodate some short bolts and a home cut shroud cover or better still some salvaged coverings from old 50cc scoots ( stock exhausts tended to come with a fancy exhaust cover, and its upcycling/recycling old to new).

    love the bottle idea could it be adjusted and hooked to the main tank as an extender tank ( giving an extra 1-3lt fuel capacity ), a feeder coming from main tank into aux tank giving you nearly double the fuel capacity ( xtra long riding times for all those lovey road in norway).

    done some reading up and the 66-68 version CT90 ran with the same front end as the cub , they then went telescopic front end , so you could keep the same front end and have that 66-68 style CT90 but a modern counterpart ;) no need to rush and look for pitbike forks, but could be an added modification for buyers if the wished to that the 70's style ct90.
    they also did a 110 version , but the ct70 - ct90 kept with the 3 speed semi auto motor and had a converter with a leaver under the motor to change ratios for offroad/on road

    the stock pipe will kill the 140cc engine. as for the forks, if you ever rode it you would understand, i need a disk brake and convensional suspension up front or it wont pass the testing i would like a ct front end, but its bloody pricey, they only seem to be in oz and postage is a killer! (have you seen the worlds fastest postie? google it!)
    the bottle was a temporary solution i used when i was test riding it, the standard tank is about 2L which gets me around 50km at most on the 140cc motor

    You got any old CB100's floating round up in Norway fella ? word on grapevine says they fit right onto the front end of a C90 ;)
    may mean a trip into sweden for breakers parts if not but they look like the best place to start, better than them old pit bike front ends to i would think. also look at the CB125 to i think both could be candidates

    loncin forks should fit they come with a disc, do you use salt on your roads as we do



    a140 will take some stopping, diesel Dave on Honda 90 forum did that conversion he said it went like hell but would not stop
    good luck with your project

    i know cb125 drum forks are a staright swap, but i wanted to do some making.... and if i go down the route of pitbike/mx bike i have the option of setting up the forks with different springs etc, not too many spring options available for 30 year old cb forks....
    it is a bloody laugh with double the power than standard, the front wheel stays up in all gears....

    so where was I?
    oh yeah, as the new motor was a manual engine i had to use a clutch lever.
    because of the clutch lever i had to remove the switch gear from the left, which meant making some switches up (albeit temporarily)

    WP_20160813_14_42_15_Pro.jpg WP_20160813_14_42_24_Pro.jpg
    not pretty, but they do the job, its blinkers left and right and light, dipped and highbeam. i have an extra switch there for future use.
    so next was the extra fuel bottle, the 2l tank wouldnt do here at all, petrol stations can be quite far apart, and with a 100 per cent increase in power i was sure i was going to burn through fuel fast.
    I looked at several options, but the cheapest and quickest was a camping fuel bottle and a bicycle water bottle holder.

    looks nice right?
    i think so anyway.
    what i have missed out here was the process of cutting the legshield to fit the carb....
    I also painted the legsheild mattblack as the gloss on there wasnt very good...

    WP_20160814_15_32_45_Pro.jpg
    also note the fuel hose has its own hole in the legshield...
    anyway after a bit of paint it was ready for some testing...
