So I’m considering a billet case that has no room for a pump, for the guys already doing this, when you’re out riding how do you judge how much oil to add when filling up? Let’s say I’m going a couple of tanks away from home but the garages are sporadically placed, what do you do to ensure the correct ratio? Do you go off the pump in litres added? I’ve run strokers all my life but only ever on pump and I’m worried I’ll get it wrong if I go this route.

I used to carry 2 125ml containers with 2 stroke oil, so I could put 5 litres in and add oil. To be honest, I never went further than a tank full 😬

similar to Ian except 250ml bottles marked up for mix ratio Dusty had a good idea about using a syringe and keeping oil in oil tank … but I aint got one of them mart

Keep the oil tank and fill it with oil but blank off the outlet
Buy a large syringe
Download one of the apps like the castrol one that you put in what ratio want then stick in how many litres you have just put in and it will tell you how many ml to add
That's the technical way
Simple way is as above with either 125 or 250 ml bottles for 5 or 10 litres
Easy to judge accurately enough for part 5's or 10's

Thanks I’ll go that route.

My bike is premix and i mix the oil to how i drive that particular day. Most of the long rides are with the cafe racer crowd and i would on average use 3 to 4 tanks of fuel. I then carry the oil with me in a rucksack. When Bimbling around with the cafe racers i tend to use a premix ratio of 40:1. This is due to the slow speed of the rides and if the premix ratio is lower people behind me start complaining about the smoke and the smell they have in their Jackets If i'm going out for a proper ride i tend not to go so far and usually put a 1 litre bottle of oil under the seat and make sure the tank is full before i set off. I then make sure the premix ratio is 1:28 this ratio is for really flogging the bike. Oil seems to be more and more difficult to buy once under way, thats why i always take my oil with me. To get the premix ratio correct i use an app which is on my telephone. i just select the premix ratio and type in the amount of fuel I've just tanked, the app automatically tells you how much oil to add. On the side of the bottle there are marks usually at 100ml. It is not rocket science so a little too much or a little less is not going to destroy your engine. Just make sure you leave some space in the fuel tank for the oil you have to add. Once the oil is added you have to swish the fuel around to mix it, this is easier when the tank is not brimmed.

It’s not straight forward then, I might go steady to start then ride it like I stole it then steady again, it’s a nightmare. Unless 1:28 will do all the time?

Russ have you thought about machining your case and bolting the pump on? If it's for the shocker you could make a mad housing for it to suit the rest of the bike.

It’s for the shocker yes, I’ve got the pump built to suit the build too but can’t find a billet lock up with pump facility, could Norbo’s polished case be altered to suit then?

Like i said it's not rocket science, if you want to thrash it and you mixed it at 40:1 lick your finger stick it in the air and just add a bit more oil. If it's the other way around the people behind you will have to put up with the smoke. In the Uk i guess you will be riding with people that like 2strokes so not so much of a problem.

No idea it's a question of fabrication and maybe the thickness of the case.

Good advice from the lads, but please note; premix is not an exact science. It's not correct for every speed, the LC with a pump, on full bore is getting lubed at around 20:1. At idle its around 90:1.

I want to run a pump and Dave had mine rebuilt by yourself for this engine but I also want a special case which nobody makes hence the question, might have to bite the bullet and just thrash it everywhere!

I know. I'd go 25:1 and carry a spare set of plugs. According to how you ride you could then try 30:1. Starting off heavier is the way to go. Keep an eye on the jetting.

I do about 33-1 which is like 30ml of oil to 1 litre of petrol
5 litres is 150ml 2 stroke oil 10 litres is 300ml
5 litres is officially 151.515151 !
I carry 2 bottles ready measured out for either 5 litre or 10 litre fill up but if you just get in your head the 30ml of oil to 1 litre of petrol

NORBO now has the billet lock-up clutch kit that takes the oil pump.....I bought mine from California from Mattoon before NORBO had got them in stock so I paid a bit more for mine but excellent upgrade and really nice looking....hope this helps ZiG

Ah O.K ….. yes dip and polish is a great idea and wouldn't be overly expensive to do either , nice one

I use premix at 50:1 with Motul 800, jetting is correct for this mix
I carry 3 x 100ml oil sample bottles under the duck tail, the oil sample bottles don't leak as they are designed to send, well, oil samples
Each bottle is good for 5 litres of fuel, if its 4.8 litres 100ml still goes in
As said above premix is not an exact science
Yes I get complaints when the bike is smokey
I prefer to call the blue smoke coming out the back as rust proofing for those bikes following

If your mixing in the tank don't fill it up completely, allow room for "sloshing" the mix around. Do it in stages and slosh the tank around in between stages, might get funny looks but who gives a shite!

And don't freewheel down a long hill... with the throttle closed... (unless you got the clutch in!!)

No throttle = no oil. Would take a long and steep hill to starve the oil supply to ensure a seizure though.

Go down hills in a high gear so engine is hardly turning over and blip the throttle !

I've seen in the owners handbook for (from memory) a Puch Maxi (quality moped in its day) "When doing down long hills, open the throttle regularly to allow oiling of the motor".

Same at traffic lights and in traffic , pretend your a scooter boy and keep blipping the throttle. 😂

I hope this app isn’t too expensive....especially since the calculator on you phone will give you exactly the same answer.....i.e. 5 litres of fuel, 40:1 ratio..... 5000/40=125 👀
