Hello everybody, Not been on here for a while, I am currently building a 1978 xs 250 from scratch into a bobber. I have gone for an 18 inch front wheel and a 16 inch rear. The rear wheel came from a 250 custom model the rear tyre size is 120/90-16 ( standard size ) I am looking for the largest tyre I can get on the rear for that fat look, Does anyone know or has anyone experimented with this size tyre ?? I currently have an 140/90B-16 AVON AV72 77H R RF COBRA on the rear, The wheel will fit on only it is ( standing at the rear of the machine) very close to the swing arm on the R.H.S. and very close to the chain on the L.H.S. Has any one had any experience with this?? I have maybe been thinking of a 130/90-16 ?? Can anyone advise

Hey Unk I have been restoring an xs 250 just seen your post those triple trees on the top of the forks I took mine off, Removed the paint with some 120 grit wet and dry then used 400, then 600 then finished off with 1200 wet and dry then I polished them, They came up a treat very shiny can see my face in them now, Good luck with the resto project.

Dirty DT, so do you think a 4.00-18 would fit on the front without the tyre touching the forks ??

Can anyone help I have an xs 250 project under way and I want to know will a Dunlop 4.00-18 tyre fit onto the front wheel ?? I currently have an Avon Road Rider 100/90-18 on the front the wheel is a 1.85-18, I have been told that a 4.00-18 you cannot get un yet I have seen a few bikes with these sizes tyres on with the same wheels, I think the guy in the garage where I purchased the Avon from just wanted the sale and doesn't know the meaning of customer service, I was charged £90 for the Avon and since seen it on line a lot, lot cheaper, The tyre I am thinking of is a Dunlop 4.00-18 does anyone know if this will fit ????

Hi there is a place where I live here in Plymouth Devon called Art Attack, their number is 01752 651586, I needed a Honda badge for my xr 250 Honda and they made me 4 transfers for £10, It was Honda with the wings on top, They have a computer that will print off what he has got in his catalogue , All I had to do was give them a card the outline size and they produced the size I wanted, They are on Facebook as well as their own website give them a call.

Hi Everyone, Does any body know the dimensions of a fuel tank on an sr125/xv 125 or a xv250 fuel tank ??

The dimensions are length of tank, width of tank inside/underside, distance between rubber mounting points at front of tank ? the current tank I have is an xs 400 fits fine however I would like it to be shorter, Can anyone help

Hello everyone I am building a 1978 Yamaha xs 250 does anyone have a picture of how the half moon collects on the down pipes at the cylinder head with the exhaust flanges fit in many thanks Combat41

Thanks mate, Are you talking about the top of the bearing at the lower end of the frame column, However it seems to me that there is nothing to hold the top of the lower bearing ? and this may come loose ? How do you remove the lower seal in the frame ? is it a push fit ? i only have a haynes manual for reference although i have a good engineering back ground, Any info will be of help

Hi everyone, Does anyone know where i can obtain a fuel cap for a tank on a xs 400 custom, I have tried an after market product which fitted but would not close, As i understand a lot of these caps look the same but are different sizes can anyone help??. Regards

Hi everyone, I am currently building a bobber from an xs 250 1978, I have purchased a set of taper race bearings for the steering from a company called pyramid parts, However on attempting to fit them they seem to be too thick in size as before i replaced the top yoke there was not any thread to attach the castle type nut that is at the top of the bearing assembly. They advertised them as for fitting every year from 1977 onwards, I have two frames a standard 1978 xs 250 and a 1981 xs 250 custom, These bearings are the same on both frames, I am waiting to hear back frome the company as it maybe that they may have just sent the wrong part. Has anyone out ther encountered this problem ?? Regards.

Does anyone know where i can get a pair of exhaust flanges for an xs 250 ? Also does anyone know if a pair from an xs 400 would fit ??.
