Frame rail modification to allow stock primary adjuster to fit through frame.

Joe, I don't know exactly where the access area you made in the frame is located, but if it's in an area that sees much stress I'd be tempted to weld a flange on the flat plate both on the inside and along the long straight edge.

Looking forward to seeing the finished piece!

The engine is rigidly mounted and contributes to the structural integrity. I was going to make the loop continuous but the oil pan interferes. I added the cross brace when I did the first configuration build. By welding the tube and gusset in place before the piece was cut kept everything in alignment.

Wouldn't a piece of tubing in that gap allow the space you need and be far stronger?

Looks good Joe with the engine adding to the stability. Just keep an eye on it.

Unless the tubing was really heavy wall it wouldn't add as much strength as is there now unless it was gusseted as well. Why is it that no matter what you're attempting to do clearance always seems to get in the way?

Tubing+gusseting is what I meant.

I considered putting a piece of 2 inch heavy wall tubing in there vertically. the adjuster would pass through it. My son worked as a fabricator in a Charlotte Nascar shop back in the late nineties and he thought just the outside half donut was enough because the engine is rigidly mounted ... I added the gusset plate which he said is overkill but welded it up to make me happy.

I like your attitude. I sometimes get action for being overly careful when it comes to safety but I've seen the results up close when things aren't done properly. I'll continue to err on the side of safety.

The other thing to remember is that it's usually easier to do something right the first time than to cut it out and do it over once everything else is in place.

Keep thrashin' on her Joe!

Well brought the new bike out to Maxton for the last meet and there was strong head winds ... not likely I was going to advance my record with a 15 mph headwind so I wrenched on my nephew's bike ... It is fresh and ready for next year ...
