Yamaha 1981 RD250LC
Hello, I am restoring a Yamaha 1981 RD250LC
I have purchased a set of JL Pipes and fitted to bike as per picture,
the problem is chain is touching the left hand pipe, well there is approx. 2-3mm clearance but when spinning the back wheel whilst sitting on a rear wheel stand chain does touch, grind it occasionally, so I can only imagine it only being worse when riding on the street, bumps, drains,
so my question is has anybody else has installed these pipes on their RDLC and had the same problem,
and I will add some pictures and somebody may see something obviously wrong or should be different,(pic needs to be rotated 90degrees)
any advice, comments would be much appreciated Cheers

Hi Neil and welcome.
Any chance the rearsets/mounts are not completely straight? They get pushed in towards the wheel if the bike was down sometime in the last 30 years or so.

Thanks for replys
silverstrom if I put extra washers between the pipe mount and rearset it actually does the opposite, pushes the pipe inwards
I will check rearset for straightness?

What Jon W said ^^^^^^^
I have had similar fitment issues with an RZ350 that has fallen a time or two. I believe the LC is similar. Run 2 long bolts into the weld nuts on the welded on frame bracket mount with an extra nut on the outside (the bolt head side) of the bolt. Screw it in and tighten the extra nut on the outside. Then you can lever the frame bracket to straighten it out without breaking the weld nut off. Also I have used 2 big crescent wrenches on that same bracket to bend it out some. I hope that made sense.

Re: Yamaha 1981 RD250LC
thanks for replys everyone,
it seems like the left hand foot mount has been pushed in, I will attempt to bend the mount back out ,
and see how that goes , hopefully enough space between chain and pipe
thank you again Neil
