Hello gentlemen hope all is well. I need some advice or insight if I may.i bought some lsr +2 a arms. I installed the lower a arm for a mock up because the instruction stated that some quads such as 400ex etc need to be notched to allow the zerk fitting to clear the frame.my question is has anyone done this and how much do I have to cut out.i dont want to cut out too much thanks in advance. By the way, it is on a 1988 250r.

Can you post pics? If there specifically made for the 250R you shouldn't have to do any clearance cutting to make them fit.

I don't recall having any issues when I ran Lonestar on my 250r. Banshee was an issue. You can use a few rachet straps to compress the front suspension and see if it clears.

I guess some Posters have not built a 250R in a Long Time...LOL

LSR A-Arms are not the only ones that you need to notch the frame to clear a 'Zerk' fitting, even A-Arms have changed slightly over the last few years.

Take your 'Zerk' fitting off, rotate the A-Arms up through full travel, this way you can see how much to notch. Typically at BDT we notch a .500"-.625" diameter, from the edge of the bracket half way in. You will end up with half a .625" diameter or .3125 radius cut.

Great job cmorris...!

I think what has happened overtime is some A-arms manufactures have moved the Zerk Fittings out of the old standard location, obviously they have not considered interference with the frame. I've seen this the past 4-6 years.
