Putting things in places they ought not to be (250R Hybrid Motor build)

[Billy Golightly]

I had planned to use a nut, but I couldn't find one, and at this point I was not making a special trip into town for just for that. Normally I try and do the same if I have on available.

[Billy Golightly]

Are you going to build a head stay?

Not for the immediate future - maybe down the road. A lot of people seem to take the head stays off and throw them away on the big bores anyways (I read something one time about them warping the base from torsional stress if they couldn't freely torque around?) Dunno whether thats true or not. It looks like a good place to mount the coil at for now, maybe some sort of a pipe mount on the opposite side also.

[Billy Golightly]

Yup!! Especially when cutting all-thread!

I seriously am envious of the fact that you found the "intake boot" laying in the middle of the road. THAT made the entire build worth it LMFAO

Screen cap from a video about a year ago - at some point I'm going to put together a little 15 minute or so documentary type thing on the build, and this is captured from one of those clips...

That's what we do with the Suzuki's. The frames flex a good bit and if you tie the head in to a flexy frame then you're looking at blown head gaskets and possibly a crack head or cylinder. I wouldn't run one on this build either, just make sure it's all tightened down real well

i think billy found the hose first and decided, "Hey, i bet I could build a motor around this hose". ;-)

Look in the middle of the road for one...LOL

Ok, but keep it in mind.

Head stays tie the motor in with the frame making it stronger and it cuts down on vibration, in fact kawasaki works teams for- MX, SX and off road teams tested different types, thicknesses, and materials to cut down on vibration & add strength to the frame. I have also seen these on other factory bike brands. All factory bikes are hand shimmed to perfection as well.

Just my two cents.

You might want to drill and wire that bung plug due to the course threads.

[Billy Golightly]

Yeah...that is one thing I had noticed I did not think of at the time, was using finer threads. I'll definitely take that into consideration.

.... but I actually FOUND the original piece of hose this was apart of LAYING IN THE MIDDLE OF THE ROAD on my way into town one morning. I actually saw it and thought "I wonder if that is the size of hose I need for my Rotax intake boot" stopped, back up, threw it in the bed of my truck where it rode for several days till I got back into the shop and tried it, and it was EXACTLY the right size.

THAT, my man, is Divine Providence

Use a copper, soft, crush washer & Teflon tape the threads. Works like a dream.

Wow nice! took me three days to read this

[NeverLift]

Anything more than a 5 second run yet?

[Billy Golightly]

No, not yet...Had a lot of other going on. Maybe this weekend? Next weekend I'm out of town, and then the following weekend is prepping for the Imperial Invasion, and then I'll probably have to work for a couple weekends in a row after I get back from there, and then it'll probably be Trikefest before I know it...
