Thanks Tremor, that is what I was looking for. I love the KLX, and its paid off, so I just like to see what I can do to it within reason. I also have a jeep that I like to mod, but its a lot more expensive.

 

What kind of an A/F ratio am I looking for with this 351 kit? I'd like to get it dyno-tuned with a sniffer, just not sure what I'm shooting for..

 

No prob! Oh, and I replaced the word 'Camshaft' with 'Crankshaft' in the 'knife-edging' portion Sometimes it's downright shocking to go back and read my own posts a day later.

I could just imagine some guy reading that saying 'good gawd, this idiot wants to knife-edge a camshaft'

 

Would it be possible to post the 331 vs the 351 dyno charts (or just the 331 chart). I'm interested in seeing how they compare. How does the vibration level compare between the 250,331,and 350? Do the big bores vibrate significantly more? I want more low end and mid range torque but I also have to ride the street so increased vibration and early sign off are concerns,as is fuel consumption. How would the 331 or 350 do on a 60 mile round trip street ride at any where between 55 and 70 mph?

 

I never got the chance to do a dyno run on a 331. The balence is closer to the 300.
Stock carb & exhaust I believe Bake got 60 MPG?
