Could we please use another battery other than the one provided by PRD(not enough amps to start motor after timeing change) We need a 10ah battery so we could use the onboard starter. Dimensions would be close.

Frank,

I must agree with you. The PRD provided spec battery is not adequate.
Greg

Guys the PRD battery is NOT spec. on the PRD rules. I will post the rules and you can look for yourself.

Hey Chris,

It says here: "All components must be O.E.M. unless noted. "

I stumbled across a guy who will disect the rules to the nTH degree, he seems to be a professional witness! LOL Maybe we can get him to disect that phrase.



Geno

Gene, 90% sure the battery is NON-Tech. You funny guy. need to stay off of ekarting it can wrought your brain. Hope the eyeball is getting better don't want any excuses.

LOL

Yes, eye'ball' being the key...

Well, hopefully it all works out. I'm still pretty confidant, but there is now a delay. Will see how it affects the karting season. Certainly going to be a bit interuppted. And not as smooth as I had hoped. I was looking for an advantage for myself going in, and now seems that is delayed anyway...

Plus with Frank tweaking the h*ll out of that PRD, and needing an electrical grid to get it started, who knows what I'll need to hang onto his tail!

I was planning to run the full season, which will be the first time for me, so hopefully I'll be able too...

you will be fine. don't strain that eye ball on the computer screen too much.

Yes, it's a good point. These poor old tired eyes have been staring non-stop at computer screens for too many years. <sigh>

On the positive side, I sent out some spies, and I got a picture of Frank working on his PRDs!



I hope that link works!

go frank go. but you still need to look out for that monster Phil built for my son.

Indeed, that is one quick kid, with a good motor clearly. He steps up into the Senior class for his first two races and puts it on pole with 65lbs of lead covering every inch of his seat. And yet he was nice enough to show me a lap around the track during P2, and even waited for me when my engine stubled coming out of the pits. Nice kid!
