No worries guys. Octane rating does not change. Here in Belgium we use these fuels for years. There has always been some ethanol in fuels, they just never labeled it that way. Over here the best thing we got 98 octane with a E5 rating for our oldtimers and 2 strokes. The only thing you need to take in mind is to have ethanol proof fuel lines. Most lines available on the market now are. I just replace all mine with E85 proof ones. Never had any issues even when running E10.

@spookdog cheers I’ll have a look at that too 👍🏻

I’m guessing that people are still running the power jets on their carbs when they state main jet sizes?...

@kevb1967
That’s a bargain, it looks great. Most people are scared to take the gamble and get their hands dirty. It’s the best way to learn if you’ve got no one to teach you though. Even if you had to rebuild the engine it came in at a good price...

@theportingmaster nice info thank you

@ninja Yeah the bottom. Yoke may differ as fhe head light brackets fasten to the yoke.

I am sure it will fit, but you may find you have problems mounting the head light.

@DtxPower Best jetting for Athena 170 is 300 main jet on the
standard Mikuni tm28 carb but with the powerjet blocked off. Just cut the rubber tube in half from the float chamber to the powerjet then block the 2 halves of the rubber tube with a couple of 5mm threaded bolts or similar.

@calum You would think that having the nipple at the bottom would aid bleeding and reduce the air bubbles, but I guess that gravity plays its part and adds disturbance to the fluid? I suppose that bubbles rise to the top and having the caliper upside down may affect the flow as well? I'm no expert but I'm sure that there's been some study somewhere. If you look at most vehicles running disc brakes, the majority have their location's at the 2-4 o'clock position. I guess that's for maximum performance, it would be interesting to see if you swapped it for a left hand unit, with the bleed nipple at the top, would you get better braking performance and easier bleeding? There's always plenty of Ducati monster calipers on ebay and making a new bracket wouldn't take too long - well worth a shot. 😉

@ringo67 isn't that always the issue and yeah not sure on emissions

Just gotta keep searching ebay bud 😁

@declan That's what the Spigot ring is for bud.

The problem is, is there enough metal to machine away.

The options are, weld it up, machine it down Machine it down, make up a spigot ring Machine it down go with the next available bearing size

For the moment, the bike is again running, so as I say, I'll put the wheel in the loft and worry about it another time.

@kevin
I want to go with a 2.0 or so. I don’t know the increment’s. I have a 2.5 fitted ATM...

@ 140927064342 that’s the item number, sorry not too hot with computers

@perky there are two types be careful, one has a round splitter box and one is oblong that is the later one, the problem arises when the oil pump cable goes into the housing and you try to fit the retaining clip and it’s the wrong length.

@spookdog 2007 IIRC

@atraiss Yeah, a dodgey connection though? When you're going over bumps and stuff. Doesn't sound ideal.

@spookdog sounds like my old lady....she keeps saying she's strawberry blonde but I took a photo of her to work and they all voted "rip roaring ginger "!....lol.

I don't mind the idea of the motorcycle suit with the airbag in it. If it makes it safer to ride then I'm all for it.

@calum I will agree with you about the sweet spot....RD 125, 250 ,350 ,500 not counting the 50 or air cooled modles as well as rgv 250, 500 plus the Dt modles......CR's....KX's the list goes on..its just the sound and smell of a two stroke preferably with a non standard pipe/s . As for electric bikes I'm coming round to these as I like some of the e-mountain bikes but at around 3 grand for a good one I can get a well sorted DTR for that. Plus I've had motorbikes since I was 18 and have never considered myself a biker but just love riding and tinkering with them. But due to my wife being ill and work have had a four year break and I'm now looking forward to getting back into them and getting a DTR is now the goal.
