    Hi Cape Cod Bob.

    Thanks for your reply.

    The year of the Bike is 1979

    Colour Dark Blue

    I am in the UK, But i was told that the bike was a USA import.

    According to your link the closest match is the USA 1979 XS1100F (serial 2H7020101 with my Frame number 2H7027751)

    any other parts i have ordered was for the XS1100F and these all fitted fine, however it is this top part of the front break hose that just does not match and we dont know why. somebody susgested it may be a USA style larger handel bar issue, if so then we do not know how to order the correct part.

    Hi Cape Cod Bob.
    Thanks for your reply.
    As far as I am aware the bike is original.


    I have received a local contact to get a new top pipe made, so i am going down this road at present, to get the bike back on the road. However it is confusing and somewhat annoying that the parts ordered did not suit, which can only lead me to think the bike is now not original.

    Hi Cape Cod Bob.
    Thanks for your reply.
    We have emailed Wezmoto who supplied the Goodridge pipes with the required pipe length; however we have not had any response yet.


    But as time goes on, it might just be bite the bullet time and pay over the nose locally to have a pipe made, just to get the bike back on the road.

    Shame I know, but little other options.

    Cant even find online a drawing or schematic of this pipe to check the correct length, just to see if what I have is correct.

    Thanks anyway for all your help.

    i would have thought that the hoses would be the same unless there is a big difference in handlebar height. has someone put different risers on your bike?

    or maybe goodridge hoses fu**ed up with their hose, it's too bad you cant find someone that has them in stock so you can measure it against what you need

Based on your serial number the frame is a 79 STANDARD XS11 (i.e. not a 79 SPECIAL)

Here are the line angles and measurements:
Banjo angles from 15* to 20* should fit fine.

M/C - 20-1/2" (1 line banjo bolt) angled banjo at the m/c, and a straight banjo on the "Y" splitter

"Y" splitter- (1 single line banjo bolt and one 2 line banjo bolt)

Front Calipers - 22-3/4" (1 banjo bolt each caliper) two angled banjos at the "Y"splitter and a straight banjo on ea. front caliper

Rear: 19" straight banjo at the m/c, and an angled banjo at the caliper

Okay so I have a 2003 Yamaha TTR-125 dirtbike, it is NOT electric start, it is kick-start. All of the plastics were replaced so I do not have the original stickers on it with the model, therefore I forgot...

There is a frame number stamped on the frame neck. If you call a dealer they can look up the year and model using an ID microfiche. Next to the stamped frame number there should be a riveted plate with the VIN number on it . If this plate is still on your frame it also has the model number and the model year of the motorcycle clearly printed on it. All Yamaha dealers have the ability to ID your machine using the Vehicle Identification Number.

I have got two yamaha late 70's early 80's (not sure exactly how old) is 175 and other dt 250 how do i get a log book for them? many thanks Keith

IF YOU DONT HAVE THE REGISTRATION NUMBER, THEN YOU WILL HAVE TO RE REGISTER THE BIKE, ON THIS MACHINE YOU SHOULD HAVE A MATCHING ENGINE AND FRAME NUMBER. AS DVLA ONLY WORK ON REG NUMBERS AND NOT FRAME NUMBERS MY THOUGHTS ARE THEY WILL ASK YOU TO REGISTER THE MACHINE USING A ( Q)PLATE THEY USE THIS SYSSTEM WHEN THEY ARE NOT ABLE TO OBTAIN THE EXACT DATE OF 1ST REGISTERED. CONTACT DVLA FOR A FORM http://dvlaguide.co.uk/index.php/dvlaguide/register_an_old_vehicle/

Hi i am lookin for identification number for 650 kawaski atv. does anyone no where if is located? how many digits does it have?

The vin number should be on the left hand frame rail. Look forward from the left hand footpeg and the 17 digit vin will be stamped into the frame. The newer models put them on the rear of the frame.

I have a yamaha dirt bike that someone stole and

Check the igniter. Go back to the dealer and ask him to see one. Then go back and find it on your bike. Yamaha's usually have them under the seat, or left side. But I don't know exactly what year you have. Run the VIN on the frame under my tips and tricks is a web site that'll break it down for you.

Which '84 yamaha 3 wheeler?

Somewhere on each frame there will be a frame number, usually on the steering stem in front of the gas tank. If you can't find it then call a dealer and ask them where the number is on the frame. Give the dealer the frame numbers and they can tell you all about each bike.

Please rate this solution. Thanks Balderas! :)
