Holy grail of frames I found it......

I can not do quote in a box today. As to post #9


"I like the idea of putting a 430 in an 83 or 84 500 frame with the ITCs out back. The milk truck frames for the 500s had a bend in the front down tube to clear the exhaust. Not sure if the 83 250 frame had the bend, if not, the 430 may not work in your 250 frame. Anybody know if the 250 had the bend in the down tube or can you see it on your frame Bill? "


The white frames, not the four strokes have the front tube with a bend or sweep. The 1982 and a half silver streak 500 had the straight down tube and the engine fit. I put a 500 engine in an 1982 auto frame and it works, barely. I had a 430 engine in there for a while as well. Just can not go the other way, earlier engine needing that squashed tube for clearance near the left foot peg.

I find the power characteristics of the air cooled 500 more enjoyable than the 430 at least the water cooled 430.

I went to a bit of trouble to get the water cooled dual shock frame but did nothing with it as of yet. The white frame has the best airbox in my opinion and the tubes near the footpegs are such that if the foot is knocked back the heel does not seem hit a tube the way that has occurred on the silver frame. it is not too hard to have the foot hit the itc shock though.

The XC has the center bar also.

I had a 4"x4"X 16" long with two 3/4" pine spacers 4" wide X 5" long on the outside on both ends, to hold the wr frames with that center tube. It depends on where you put the block on a milk crate as to pull the front wheel or rear wheel.

You'd be surprised how many times that center rail has saved our cases.

The wr and xc frames are the same except the xc has a tad more suspension travel.

In 1983 there was no cr / xc 430. There was a wr 430 only. Besides the 250 & 500.

The 84 250cr frame hasn't arrived yet. It's in the mail.

I have always held the holy grail of frames are the early 70s Husky Titanium frame race bikes. Like the Lars Larsson race bike.
But what you guys are doing is holy as well!!!

I made my skid plate out of 1/4" aluminum plate. I cut a slot in the middle for the center tube to "set" into. The bike sits flat & sturdy on the stand.

Yeah, I'm aware of that.

If it is an '84 250CR frame it will not work with an air cooled engine.

Have we started this thread again? what did I miss?
Holy Smokes!

I think it has at least 2 more pages to go

worst part is we fell for it..nothing accomplished either

One thing will have been accomplished, if bill actually did buy an '84 250CR frame and not an '83 he will learn that an air cooled engine will not fit.

pictures, we need pictures

Lots of pics of all the bikes.

I got 13 of Steve McQueens bikes...they will be here Tuesday. but my camera is broke. I am putting a 426 Hemi in the WR450. I made shocks from an old storm door piston and used the springs from 2 Ball point pens. I put in a huge powerband too.....should run great.

The air cooled exhaust pipe is much harder to smash. It is the cooling and exhaust that compete for space. The thought of modifying the air cooled exhaust pipe attachment to the centerline or close to it has occurred do me. Unfortunately the front wheel is kind of close in there compared to brand x.
