During the height of COVID lockdowns, I drove to --GASP!!-- Wisconsin to pick up my new bike. After a decontamination at the border (just kidding), I wheeled the 300RR into our new virtual Zumba studio. When Michelle wasn't filming, I began shooting the necessary glamor photos, one of which is shown above. This was by far the prettiest motorcycle I'd ever owned. But would it perform?
No, it would not.
My leap of faith seemed a bit foolish the first time I rode the bike. I have never experienced such a poorly jetted, brand new bike. Every twist of throttle, when the RPMs were just above idle, produced a bog which lasted about a full second. And the throttle stuck open after less than 5 minutes cruising in a straight line through my pasture. Had the dealer been closer to my house, I would have driven straight back to where I bought it and left it there.
I kept increasing the size of the pilot jet, and the bogging gradually disappeared. But nobody...and by that I mean not a single internet discussion forum junkie in the world...was talking about having to re-jet from a 38 to a 48 pilot. And the air screw was only turned 3/4 out, which meant it was borderline, and probably should have been a 50 pilot. This just wasn't right.
I also felt that the bike was using a lot more fuel than my past 2- strokes. After a 1-hour test on a grass track in my pasture, I measured fuel consumption at 1.4 gallons. All the other 2-stroke bikes I'd owned were pretty consistently using about a gallon an hour.
Then I decided to test the engine compression. Surely the engine must have an air leak somewhere, causing a need for more fuel. My compression tester, which had been used maybe twice in the past 15 years, registered 130 PSI. Not good.
I called the dealer. They agreed to look at the bike and tracked down the problem quickly. The Beta factory had installed a European-spec needle in the carb. In Europe, to meet strict emissions laws, the bikes are sold with very lean carburetion and throttle stops. The carbs are fitted with needles never intended for the USA market. The dealer agreed to install the correct USA-spec needle.
The dealer also suggested I get a new compression tester. They measured 185 PSI on both my bike and their demo 300.
