I think you think i'm talking about cars which have computers and can run off various grades of fuel without any intervention. The computer does it all.
I've used various grades in my car which is carbed and does not have ECU, and 95 or not, E10 has a significant impact on the idle quality and a very noticable lack of power. Infact it was crippling- the car runs a bit lean anyway.
It was very interesting when I first experienced this (E10 is much cheaper abroad than E5, I was being cheap - next fill up with E5 the vehicle returned to normal operation).
The fuel contained is still 95 ron sure, but from what I could research there's now up to 10% less of the 'actual' fuel, which didn't seem to make much of a difference when actual easily 'combustable fuel' was at 95% (e5), which is up to 5% Ethanol (most of the time 3%). I suppose you could think about it like changing pre-mix on a 2t from 50:1 to 30:1 (there's only like 1.5% less petrol) but it's perfectly usable and safe and not too lean.
But if 90-95% true petrol of a fluid that is easily combustable then it's going to run lean, and more than reasonable.
When the forecorts start changin 95 to e10, i'll definately be experimenting with the above as it'll be cheaper in the long run than buying 98. There's been no need for me to until the near future.
In places of E10 it is recommended by manufacturers to increase jet sizes.
But in the end: I'll have to try it out and adapt
Or am I totally wrong? I mean, ethenol does burn of course, but not as well as petrol. It made an effect on my car, and then after 7 hours of burning it off and replacing with e5 95, all was grand. Maybe it was just shitty ukrainian fuel. I'll give it another go when it's in the petrol stations. |
E10 will resist knock more than E5, you could try advancing the timing a few degrees first before mucking around with jets. But if it is running lean as confirmed by exhaust gas analysis then you need to sort that first anyhow.
I suppose you're running a relatively low compression ratio and it's not turbocharged, with more advance you'll make more power. ____________________

Ohhhhh I see.
Nahhhh, the vid was done outside my house, after I got home.
(I wouldn't have been so gauche as to do a excited-girly stylee video in front of the shop where they fixed it. )
Crikey ... give me some credit for being *slightly* cool )
So it was warmed up already, cos I had ridden it back from Greenwich to ma hoose by then.
In fact the hottie at the shop, who reminded me strangely of our very own Grrr666 (same chin *wibble* ) warmed it up for me.
... showed me how the choke was a bit dodgy, rode it up and down to check it was going to keep ticking over, and all the time I was just watching thinking "Nice arse, bit skinny, but worth a perve"
Choke, what choke?

Did a bit of mild porting to the cylinder head of my project bike.
The idea is to put back in any horses it's lost over the years, and maybe a few more. It's getting fresh(er) valves and valve springs, from Germany. It also has lighter aftermarket ignition advancer springs (from Z-Power) a custom 2-into-1 intake (which I've heavily flowed), and this mildly ported head. The porting I've done (just with a Dremel) is only for flow, not volume, and it's just taking out hard angles and casting flaws, because the standard cam is going back in. I haven't found anyone who makes a performance cam for this bike, although there are performance valves available (which I'm not getting, as they're very expensive and as far as I can see they also increase the size of the combustion chamber with their concave faces).

Changed out the brake fluid on my YBR. Two years since purchased new, but 2015 model year (old dealer stock). The fluid did not look this bad in the sight glass; I was surprised when it came out of the caliper looking like tea left overnight in the pot. 4,315 miles on the bike when I performed this service.

Brake reservoir says use DOT3 or DOT4. Did an internet query; DOT4 has a higher boiling point, but higher hydroscopic properties (absorbs water easier), DOT 3 lower boiling point (401F vs 446F) but has longer lifespan in service due to lower water absorption. My single piston YBR front brake got new DOT3.
New brake fluid resembles light salad oil in the tube during brake bleed. I was pleased to see Yamaha put in a small stainless deflector in the bottom of the reservoir to prevent squirting during the brake bleed procedure. ____________________ History shows again and again how nature points out the folly of men - BOC |

Brake master cylinder replaced, on project bike.
There was absolutely nothing wrong with the old one, except that it didn't activate the brake light when you pressed the brake. This is how it was designed, which is great, but it didn't feel safe when I took it for its MOT. So I bought a new brake master cylinder, which had a switch fitted. It's considerably smaller, and the reservoir fills up with seemingly just a few drops, but I've hooked it up, tested it and it all works. The switch is wired in to close the same circuit as the rear brake switch. The brake does work, but at the angle of the handlebar, the fluid level reads minimal even though it's brimmed on one side.

Cylinder head coming along nicely. Valves lapped in, residue of lapping compound pressure-washered off, new valve stem steals fitted, etc. New manifold gaskets made (out of the proper stuff - Flexoid). They're matched to the cylinder head (rounded/flared out at the inrakes) and to the manifold. |

Listed the 250 Tuesday evening, sold it today. Even quicker sale than the 500, bloke just asked if it was available, was it reliable, and would I deliver. Yes, yes and maybe. I thought he'd want to come over and view the bike, but no, he had "cash waiting, when could I drop it off?". Just dropped it off, cash was waiting, no haggling, no inspection other than checking the fuel tap and the steering lock. Weird.
Anyhoo, back to shopping, before the good lady wife fills the garage space ____________________ Chances are quite high you are not in my Monkeysphere, and I don't care about you. Don't take it personally.

Decided sod it, took the valve cover (which is also the rocker arm retainer) off the head. Spotted the problem immediately.
It's kinda hard to set the valve clearance when the button on top of the valve stem decides to part company with the rest of the valve stem. It's sat all nice and shiny by the gold head nut. Cock. Explains why I couldn't get it set for love nor fucking money.

Trying to get the spec off the importer, as I know they're out of stock of, well, everything, at the moment. It's a KW157FMI engine, so I may just grab a GS/GN/GZ set of valves and hope they're not EN. Also get to brush up on DIY valve spring compressors.
I'm gonna chuck a new cam (longer duration?) and rockers n while I'm in there, this one has evidently been starved of oil at some point. Got a 150 kit sitting around, will chuck that on at the same time. ____________________ '98 VFR800 (touring) - '12 VFR800 Crosrunner (Commuting) - '01 KDX220 (Big Green Antisocial Machine) |

Today I installed those tank grips by "Eazigrip". They were not tailored for NSR 125, but they work just fine. It made a huge difference for me. I am finally not sliding around while braking ____________________ Honda NSR 125R (1999) |
