Torch,

use the shorty plug, even then you will probably have to push the tank up a bit to get clearance. If you use your heat gun, and heat a large area you can form the tank around the head so you have clearance. I used a piece of large pipe and a rubber strap, heated it, formed it how I wanted it, then used the rubber strap to hold the plastic till it cooled.

Zett, the 250F was alot cleaner at the rear of the head, but in the end the 250 2t was easier to do than the 250f.

Man, I don't know....It seems to me that the 250f is the easy'er one to do.
Easy headstay mod
No swingarm mods
Very little gas tank mod
And it looks like the tank hangs so low on the 2 strokes that it will need some modification to clear the carb,
also by using the K5 cradle I was able to keep the removable front motor mounts. Makes getting the engine in and out pretty easy (seems like I done it a  hundred times now)

Keep up the GOOD work.  I love these projects!!!

Rekluse Z-Start pro would be awesome as you will have the full manual override at all rpm's with the clutch. This thing will be a weapon once you have all these mods complete, keep the pics coming

Any issues with excess vibration in these frames? are you going to use any rubber in your mounting?

cheers

Thank you! I have no idea on the vibes, maybe someone else knows the answer to that one. I won't use rubber to mount the engine. I asked, here I think, whether the frame helped make the engine more rigid, or if the engine made the frame more rigid. I was informed that the engine is basicly a 60 pound frame brace.

Good idea for the tank! How much clearance do you think it should have? I think a half inch should do it.
