Tire Pressure? I can't believe it!

[checkcrew]

Robert,

one of my 73 Jackpiners has an EC pipe on it,
no motor mods just the pipe !!

crazy info there, hard to believe anything he built would have issues !!

I remember one time EC Birt wrote some magazine article about modifying the Jackpiner engine.
Just after that John Cobb wrote an article in Keeping Track that said, 'DO NOT do what EC Birt had specified about modifiying the 175, unless you want to destroy your engine'.  Don't know all the details of that at the moment, but I would have believed John Cobb over EC Birt when it came to Pentons.

  I got to get a low pressure tire gauge, thanks for the info.

Garrett, The best places for (accurate) low pressure tire gauges is kart shops. We only run 8 - 10 pounds in the race kart. Check out these places, or ebay.

Walmart has them for CHEAP and they are packaged just like the HIGH DOLLAR ACCURATE ones that they sell at the motorcycle shop.  Higher priced is not always better and of course cheaper isn't always cheaper either.  Never had any trouble with these.

Years ago, motorcycles came with air adjustable forks (ie.1981 Suzuki RM 125X).  Suzuki supplied a low-pressure gage with the purchase of the motorcycle.   I still have mine; both the Suzuki and gage...   I agree with Larry, the dial low pressure gages are easily found and purchased at autoparts stores, and department stores.  I think for under $15. Regardless of the price paid, don't drop the gage.  They seem to uncalibrate.   Also, I do not rely entirely on a gage to set tire pressure.  Other factors play a big part.  Outside temperature, tire age and compound, ply of tire (2 ply vs 4 ply), track condition (mud, rocks, trees, hard packed, sand), type of riding, et.al.   joe

Certainly not going to disagree with Larry or Joe. Not much of an arguer. Just know what works. I've had my low pressure gauge for .... not sure how many years. It's been dropped, thrown and even forgotten on the kart and run over. Still accurate to a 1/4 pound. The biggest issue with low pressure gauges is forgetting it only goes to 30 and (pinning) it on a tire over 30 pounds.
If you drop a gauge and it loses calibration, it wasn't worth whatever you saved.
