I picked up my frame from the welder today and the first thing I noticed was square tubing. I asked for rounded corner tubing but he tells me his supplier can't get any. I tell him of a couple of places that I could get it myself!

I did not want to wait to do over so I took it home. Got the engine all lined up thanks to the all the info here but the angles looked odd. Put the tires on and you can see whats wrong.

The tubes are just tacked in so its not hard to replace. Should I take it back like it is now and replace one side at a time while getting things level? Or get one of you guys to bend me the CORRECT tubes, fit them and then take it to the welder? By the way don't worry about the open engine, I will be going thru it top to bottom.

Stop!!!!!




Send your stuff to Stoffers

Looks like same guy that did ridereds did yours !
take it back or get your money back. That bend is the wrong radius, angels down to far also. i dont claim to have 20 something years experience, I will do it right or not at all.

I can ship tube tomorrow, let me know

Yea, send it to Dogger. He can make you new rails but needs the frame to do it. They are made for each bike so it would be tough for him to make rails and send them to you. Looks like the motor angle is too far down in the front also. The bend starts waaaay to far down on the downtubes.

OH come on!, 6063 is sooooo much better than 6061, and there's No Way you can form the bend in 6061T6 without annealing it...............

So said, in short form (by a Screw I think that's what he revealed himself to be, in day to day life) to a bloke that has worked with 6061 since he was in his early teens.

Perhaps he tested his beliefs whilst sitting in a watch tower, being lord over all he sees? But, he had his old welder (who admittedly does lovely welds) tell him the 'Facts', and that was how it was.

A 70 degree angle is a good mean angle to start with. It's easier if you cut templates out of cardboard to give yourself ideas on the shape of what you need.

I don't mind the engine angle as it is, it would give less squat to the rear end under acceleration ( what they did with 09/10 CRF 450s), but it does make the ancillaries a bit harder to do. A lot of blokes position their engines so as to induce more squat - I'm not sure if they know that's the result of their mounting. Each to his own, I guess. I've had a few people post that it makes no difference, but that ranks on the level of 6063 and squashed tubing......

Thats exactly the first thought that came to my mind!

BTW knobby, not to change the subject but I'm loving the bike in the background. While the fun factor the 500 is unmatched, If I was given the choice of "you can only have one bike" the YZ would be the one.

Here-s what I did to find the angle and lenght of the tubing on my build:

just use the stock tube you cut out and match that as a templet? simple

Ya, the YZ is a keeper

Some good ideas, thanks for the input. I'll get it right next time, one way or another. On the plus side I have material to start the lawn chair build I always wanted to do

hope you get it fixed up!!

I got it back on track thanks to a lot of help from pstoffers. Gen 3 front mounts are not working out though.

Shim it.... weld it... Done.

No No and NO!!! I'm making new ones

You da' man.

Got it done! Took it out for short ride to break it in. Bike is awesome.
I want to thank everyone here who helped me out and a extra big thanks to pstoffers for getting me the parts I needed plus all the advice. Could not have done it without his help.

Nice, clean looking job man!!!!

Looking good!
make sure to check all you bolts, it liiks like the head stay could use a little tightening.

Thanks. It's tight, picture makes it look like there is a gap when there's not.
