What about any manifolds for Universal Application?

 

I got the idea from a link posted in here:

http://ttr250.activeboard.com/t48933958/teikei-y30p-rebuild-kit/?page=1

 

More specifically these pages:

http://www.motorcyclecarbs.com/Carburetor_Holder_Mounting_Dim_W288C710.cfm

http://www.motorcyclecarbs.com/Tube_Type_Manifold_Boots_C2439.cfm

http://www.motorcyclecarbs.com/Carburetor_Holders_for_Yamaha_C707.cfm

 

I see some parts that seem like mine in there, but i'm not sure if there's one that would fit my bike.

Hello all.

I'm looking for an intake manifold for my bike.Ordering it from Yamaha would cost me 100$ and i'm looking for something cheaper.

 

I found this on ebay:

http://www.ebay.com/itm/04-Yamaha-TTR250-TTR250RL-TTR-250-INTAKE-MANIFOLD-/190666137797

but it costs the same plus the guy doesn't ship to Greece anyway.

 

ANY kind of help would be appreciated.

What's wrong with the existing one fitted to your bike?

Can it not be refurbed/restored to acceptable performance?

 The bike was not in use for about 2 years and the inside of it has cracks.I don't know if that can be repaired.

 Are you referring to this part?To tell you the truth i'm not that much into repairing and i cannot fully get it concerning the procedure.

Carburation problems? Check the rubber inlet manifold between the carb and the cylinder head as it may have come apart. The aluminium part that bolts to the head is tapered so gluing the rubber back on isn't easy. When the rubber comes adrift it sucks air into the engine upsetting the fuel/air ratio and causes poor running. It's also a very common fault and I've seen it on 2003 models. To glue the rubber back on you will need to remove the airbox, carb and inlet stub. Then clean it as best you can with a solvent that evaporates - meths, acetone etc. Then use an epoxy adhesive to coat the stub and push the rubber back on. Clamp end-to-end and put a jubilee clip (hose clip) around the glued area but not too tight. When the glue has dried (24 hrs is good) drive a couple of self-tapping screws through the jubilee clip, through the rubber and into the aluminium stub. If you're fussy, Dremel the ends of the screws inside the inlet stub.

I found the exact part of the 1999 model:

http://www.motosport.com/dirtbike/oem-parts/YAMAHA/1999/TTR250/INTAKE/JOINT%2C-CARBURETOR-1/4GY-13586-00-00

Would it fit mine which is the previous one?Looks like that one:
