June 17, 20188 yr what do people use as the lower rear mud guard? And do you buy the replica fender or a universal. Many thanks
June 17, 20188 yr There is a moulded plastic piece that the airbox is normally riveted to that forms the lower rear mudguard. Replicas of these are available. Lots of choices for the mudguard that fits behind the seat. High quality replica plastic available ex UK in white or yellow. Low quality replica plastic available ex USA in white. Fibreglass replicas are available from time to time. Universal (Gonelli) plastic rears from many sources and lots of colours - but needs additional brackets. Note that the 1974 (A) and 1975 (B) TY250 rear guard is a shortened version of the 1976 and later (CDE) mudguard if you use the original fibreglass seat surround
June 17, 20188 yr What are you using for a filter? The airbox is attached to the lower guard, normally plenty available on eBay from the states but it would pay to get a new connector tube from Clauss Studios. If you don't want to run a standard airbox a replica inner guard is available from a few different places, majesty yamaha have the inner only for 74s, DC Plastics do both the inner & rear guard for 74s
June 17, 20188 yr Author I don't really know which is the best option to go with. This is the airbox that came with the bike which has just been screwed to rear fender.
June 17, 20188 yr That's the correct airbox, if you had the correct lower guard it would have sealant between the airbox edges & the guard & small rivets holding it in place. Unfortunately it looks like part of the airbox on the left side has been cut off, it normally comes partway along the side of the guard if that makes sense This is what the airbox & inner guard should look like, see how there are some rivets at the back that go sideways This is the listing for it, from what I can tell it would probably be cheaper than just buying a new inner guard & you already have the filter & lid. In their other listings is a used rear guard which also has free UK postage so you could sort it all in 1 go https://www.ebay.co.uk/itm/1974-YAMAHA-TY-250-AIRBOX-MOTOCROSS-TRIALS-TWINSHOCK-CLASS/253683358043?epid=24020303214&hash=item3b10b4d95b:g:4A0AAOSwwAdbHpnl Edited June 17, 20188 yr by tony27
June 17, 20188 yr Author Is the one in the picture in your post the same as this one from majesty, you just have to attach the airbox to it? I have already just brought a new rear fender just need to sort the bottom out now
June 17, 20188 yr Same part but you may be missing part of the airbox were the rivets attach at the side
June 20, 20188 yr Author I have brought the whole unit from eBay, got lots of parts now ready to go onto the frame
