May I ask why cider vinegar only? They seem to be available to be in the same percentage in acidity.

Can you use cider vinegar to clean the crankcase, sleeve, piston, and head button as well?

How to reduce the weight AND lower the CG
Hi all.
Here is my Team engine - now a lot lighter and lowered CG.
The original Novarossi head weighs 103 gram. The head from my HPI Pro F3.5 HPI part #101589 weighs 72 gram and is lowered a lot (7 mm lower than the Novarossi head). The 4 screw holes have the same position, so why not put the HPI head on my Nova? All it tooked was a little bit of grinding on the Nova house. VOILA the worlds first NOPI engine!
Life is simple!

Hi. Yearh, thought about that, but its fall now here in Denmark, and the temp is already around 10º C. Going to race that engine next weekend and also in March where its even colder. With that head I shouldn't have to worry about wrapping the head to keep up the temp

Hey guys, I have a Plus-4btt that has been absolutely bullet proof and been running fine for about 4 straight weekends until yesterday. I am running A Werks #6 plug in it with the stock Mugen clutch with the same OFNA 086 pipe I have been running this combo for 2 months. I have about 4 gallons on it. I was 4 minutes into the second 5 minute qualifier. I really have not touched the needles besides an hour here and there on the HSN each weekend and no flameouts over the last 2 months. The track had a long stretch and we twist the motors pretty good but all of a sudden the thing will die as soon as I let off the gas at the end of the straight 4 minutes into the heat. Motor was running perfect, nice and crisp, and only about 255 when i temped it.
I richened the top up a little bit, set it down to get 1 last lap in, made the whole 40 sec. lap and once again at the end of the stretch same thing when I let off the gas it just dies.
Repleced the plug and richened the LSN and increased idle gap, did the same thing in the 3 heat except earlier and in the 1st lap. Only dies at the end of the straight from being wide open for a good 3 to 4 seconds and then letting off to make sweeper curve? Idles fine, sounds great but keeps dying? I did not check it at the track, but maybe guessing front bearing? Need to tear into it tonight or tomorrow any ideas? We tuned on it the whole 3rd qualifier and the same thing no matter what we did. Also tried a #5 (hot) plufg and still did it?
Any ideas besides bearing or what would cause it to die after wide open throttle would help?
