Interesting just looking at doing mine as well - m2r 140 set up for SM. How much was yours to insure/tax? Weighing up whether it's worth it Very Happy

If you happen to have a 125cc engine, then the tax is 17 a year, so not at all bad! The insurance was around 200, but this was with no NCB to put on it, and my shed isnt classified as a garage which won't have helped.


Notes for YX140 engines in roadgoing bikes;

I did find that the factory Molkt carb was a bit crappy with part throttle openings, so worthwhile getting a genuine Mikuni. The 'pre jetted' mikuni carb was very lean on the needle causing 1/4 throttle misfires till the clip was set to the lowest position. The main jet is also a little bit lean so its worth getting a jet kit around the 100-120 range to have a play with.

Throw the stock coil in the bin and replace it with a Splitfire coil setup. It wont add any extra power, but it also wont cut out at the first hint of rain. The stock cap isnt waterproof weirdly enough. Make sure whoever put the bike together faced the coil connections towards the rear of the bike or they take on water very quickly and cause the bike to cut out, i had to turn mine around.

The rear crankcase breather is a nightmare and will chuck a lot of oil (around half a litre in my case) all over the rear tyre when you run the engine at high RPM for a long time. Its fine bimbling around, but when you crack on it does chuck it out! Use a 10mm hose on ebay 2 for half a metre to extend the breather into a catch can, or route it high up and put a car crankcase breather filter on the end.

The dipsticks dont read anything accurately. This is especially bad as overfilling it makes the rear breather issue a lot worse. 800ml of 10w40, dont use cheap car oil as I tried Tescos stuff as well as some old Quantum oil and got clutch slip badly. Filled it up with some Motrex oil left over from the KTM and no more clutch slips. Cheapest nastiest bike specific oil you can find.

Fit an inline fuel filter. My tank was filthy from offroad use and grubby fuel cans so fouled the carb quickly. Most are probbably going to be the same, for the sake of 1 its a no brainer, ive not had any issues with fuel flow at all.

Talons 30T rear sprocket is good for 65-70mph on the GPS with the factory front sprocket. Im fat, and it feels like the bike cant quite max out 4th on the flat so its about where it needs to be.

Cheers for that! I've taken the carb apart already a couple of times as it was running like arse when I got it, seems to be better now but I can't tell much from just running it around the road outside my house... valve clearances were mega tight before as well which didn't help the cold start, now set properly and it's like a different bike. I'll have to get it under some proper load to see what it's behaving like.

I'm hoping as it's a British company that built it its NOVA registered already so trying to get the details out of them now.

Did you ever jave to go through the inectiom steps when you registered it? Just put a tape ,easier on mime and ground clearance is 280mm (with catch tray) and seat height is 840mm so in between enduro and trials

I diddnt get inspected, no.

Plan was to fit a seat base with no foam to get the seat height down, and fill the tank with marbles to reduce capacity. Seemed the easiest/cheapest solution!

Shocked Laughing

Love to be fly on the wall when a tank full of marbles actually does get inspected.

Is similar to how I got my TTR listed as 33hp. Socks in the airbox, 9 pairs of them.

Extra high seat base it is then, crf110 based so no hope of being a trials. Sent the paperwork off to NOVA now so fingers crossed, the manufacturer of the bike was zero help at giving me any info about it so will have to be a Q plate

Incidentally, autocorrect on my last post doesn't look like it worked! Rolling Eyes
