ZILLAKILLA Posted January 11, 2014 Report Posted January 11, 2014 I just found out that that there is a such thing as a hot or cold plug. I run what the book says B8ES. I recently got a new 10 pack that have an R (I think) on it. I haven't tried them yet. My cousin has a B9ES and said its a hot plug.... Can you guys explain the difference and what works better in different conditions. My bike runs great and starts first kick 95% of the time unless its super cold then like 5 kicks with choke out.... Any info will help... Quote
RadarRacing Posted January 11, 2014 Report Posted January 11, 2014 Lower number is the hotter plug. Stick with your 8s or even 9s. The R is a resistor plug and is needed with some digital ignitions , not needed with stock. Quote
RadarRacing Posted January 11, 2014 Report Posted January 11, 2014 By the way. A hotter plug is not necessarily a plug with a hotter spark , ot is how much running heat the sparkplug retains. Quote
ZILLAKILLA Posted January 11, 2014 Author Report Posted January 11, 2014 So can I run the ones with the R on my setup I have or do I just get the plain 8"s... Quote
tdod101 Posted January 11, 2014 Report Posted January 11, 2014 The R's won't hurt it. I run anti foul plugs b9eya Everything you need to know: http://www.ngksparkplugs.com/techinfo/spark_plugs/partnumberkey.pdf Quote
uman1030 Posted January 12, 2014 Report Posted January 12, 2014 Solid tips are also a good idea so the caps dont rattle loose ever. have this issue with my jetskis commonly before i started buying solid tip plugs Quote
tdod101 Posted January 12, 2014 Report Posted January 12, 2014 ^^^this Also I usually ditch the stock caps as well and get the nice red rubber ones Quote
trickedcarbine Posted January 12, 2014 Report Posted January 12, 2014 ^^^this Also I usually ditch the stock caps as well and get the nice red rubber ones I think he's referring to the cap of the spark plug. Most of them are threaded on these days, and it sucks when they wanna loosen up. Quote
Starwriter Posted January 12, 2014 Report Posted January 12, 2014 I always crank them tight with pliers. Quote
koneil38 Posted January 12, 2014 Report Posted January 12, 2014 I always crank them tight with pliers. We used to have this issue when I ran my NASCAR Southwest Tour Car. We simply crimped the threaded cap with a wire crimper. Quote
trickedcarbine Posted January 12, 2014 Report Posted January 12, 2014 I tighten and crimp as well. Best fix IMO Quote
