Chris;

Nice to hear that your dad will be joining the 80 roadrace group.  Now, let’s get Bill to take that TM off and put an 80 on his roadracer!

I look forward to racing with the NW 80 group at Thunderhill West in October.  If they come down I may have to race with them, especially if your dad is with them!

The starter on Dave’s 125 shifter worked great at Laguna Seca.  He’s already VERY spoiled and expects the kart the just start and idle like a Toyota!

Looking forward to WS next month.  Should be there on Friday and a BBQ and socializing sounds like great fun.

Will bring the CR80 Laydown again and plan to get more development done.  It’s a blast to drive and it would be great to have some folks to race with.  There is a group in the Northwest of about 25 of these karts.  The problem is that there aren’t many races up there that have good weather, and this racer has no interest in racing in the wet.

I believe there will be a contingent of CR80 Laydown karts at the October Thunderhill West race.  I plan to race my Modified CR80 Sprint there as it looks like a great track for a sprint kart.

DITTO!!

A few 80’s in the Nor-Cal.

If you’re able to add an ounce, the tire is significantly out of balance.  For roadracing, I always balance my tires.  Better safe than shaking.

Ask questions of experienced karters.  Bring something to keep notes in.  Use it extensively.  Listen.

[Greg Lindahl]

A talented/experienced driver can do very well in quite old and “experienced” equipment.

Use your $ to work on your driver first.

Very clean design, Ian.

Congratulations

[Greg Lindahl]

Very much so.

Check squish.

Check fuel quality.

Check timing.

Check cc’s.

Check for anything creating lean condition (air leak/carb settings).

[Greg Lindahl]

Good point Steve.  The names came about when more races were needed to support a class that was/is very popular.  Maybe one name with weight differences, as has been done in the past…  Example:  Stock Honda 125 Lt., Med., and Hvy.

There are many conservative fuddy-duddies on this forum that are more than willing to shoot down new ideas, until someone who has gained their respect changes their mind.  Little thinking for themselves…

Hi Paul.

You can either go to a Birel dealer and see if they can help, or, measure the bearings and shop them using the size as reference.  You’ll get what you pay for.  Hardware store bearings are often low cost and quality. 

I suggest bearings made by companies you recognize or, after research, are convinced build a good product. 

OEM bearings on most karts is middle-to-lower quality.

Hope to make a race at Chuck some time.

Thanks Ben.

Mr. Horvath,

I too am an engineer that thrives on building what I think will work and testing for validity. 

I know exactly what you speak of about other racers thinking that anything new won’t work.  I love proving them wrong, but it’s really not much fun when they don’t have open minds and admit it…

I’ve been thinking about power kart lifts that can lift/drop, are very light, fold flat or turn into trailers and start my gearbox karts (laydown and shifter roadracing).  Not giving up but will likely have to compromise.

Aerodynamics are my favorite pursuit.  I’ve had radiators of several sizes mounted in most locations on karts and am still pursuing more.  I’m on my 18th setup now.

Fuel Safe builds fuel cells and sells foam.  Not inexpensive.  You’re probably dealing with the problem noted above by Tony.

I use foam in my roadracer and sprint roadracer.  You must be certain to not let the foam foul your pick up system if you use it.

Gents;

Read and study Race Engine Technology and other engine technology books and you’ll know that 55 HP with modern EFI, coatings, combustion knowledge, fuels/oils is entirely possible. 

Opinion is worth $0.00.  (:-)

Hey Jason.

The TBA at Sonoma is worth a heading of its own in here.  That way everyone will know.

[Greg Lindahl]

Congrat’s, enjoy!

[Greg Lindahl]

Here in the SF Bay area a kart like that sells for ~$1,500 – 1,800.  If you can and have the mechanical skills, remove the cylinder and rock the rod from the small end and measure the movement.  Verify that it’s within the CR80 manual limits to check bottom end health.  I’m comfortable purchasing used engines only after verifying the condition, or, plan and budget to rebuild the engine before puting the kart on the track.  Belts and braces…

360 degree bumpers with on-board cameras showing what’s truly taking place would provide the safety of bumpers with the responsiblity of live footage witnesses.

[Greg Lindahl]

That broken cylinder is likely from those ports large enough to put your finger through.

[Greg Lindahl]

Ditto.

Common as dirt in many brake systems.  Sometimes leading and sometimes trailing sides. Sometimes from heat, sometimes from pressure.  Many brake caliper manufacturers vary the pressure accross the pad with multiple/different cylinder diameters.

[Greg Lindahl]

I like the “handicap” approach.  We did this a few times when there were still large turnouts and had fun and tight races.  I have two karts that fall out of the “Championship RR” classes, but would enjoy racing with the mixed and larger group of people in a “handicap” race.  But, I think that a 1-2 second faster cushion to cover drafting would be a good idea, with a 1-4 second faster cushion for new karters.

[Greg Lindahl]

Thanks all!
