I think the reason the can class is hanging on is because it's alot cheaper to run. Not near as hard on engine or clutch. If all the Yammies would be interested in runin' can I will put one together. In fact it's already together. I have a clone also, but have been dreading fooling with valve's

My thoughts are the mystery carb found on the Yamaha engine scares people away. If there was another non adjustable forgiving alternative to there carb I believe many folks would give them a try. A newbie is at a disadvantage and not staying on top of the carb during the race either makes you slow or worse yet stick an engine.

There is absolutely no magic to these carb's. It is mind boggling to me that people are worried about the carb adjustment. If you have a good engine builder, they will tell you where to set the carb. I have been tuning a Yamaha carb for 13 years and I can tell you they are a piece of cake with a Can. With a Pipe, you have a possibility of sticking a motor, but only if you do something stupid, like trying to lean it down. In 13 years I have never stuck a Yamaha motor. Now an ICA motor that turns 20,000 rpm, now that is not for an inexperienced racer.

I would rather tune a Yamaha carb than a 4 cycle carb any day.

I to have never stuck a Yamaha at Barnesville. Now Jacksonville is a little different story. Michael, Yamaha carb is not a problem. I love being able to adjust on the run.

I agree on both counts. I ran Yamaha pipe for about a year, and tuning was very straightforward. My engine builder gave me the base settings and then about all I ever had to do is just slightly tweak the high side on the track. That tweak was very easy to get right with seat-of-the-pants and CHT. With the inexpensive EGT guages now, I would think Yamaha would be a piece of cake.

I also liked the old flathead carbs, real easy to tweak on track. I really hate the float-bowl carbs like the animal and clone have. Total PITA.

We recently cooked two yamaha's rings from running lean (lost their tension).... my son had the low end opened way up and the high was way open and he kept telling me the exhaust and head temp were high.. very high...... the damn carb needle was stuck only partially open on us.. i always debur the needles on a granite plate with 320 wet sandpaper when rebuilding the carb and it still stuck.... thought i would pass this on in case this happens to ya... happy turkey day my friends

I would highly recommend you start out with can instead of pipe. Slip clutch very little to start out.
