motovintage Posted February 6, 2010 Report Share Posted February 6, 2010 between BR6ES plug and a BPR6ES plug? can i use the "p" plug in my 315r?? don't use the BP. The "P" plug has an extended electrode, it's ground strap sits aproximatly 5mm further down in the combustion chamber, some engines this creates a clearance problem from the piston to the sparkplug, the "P" plugs are generally used in 4-stroke engines that are designed for this type of plug Quote Link to comment Share on other sites More sharing options...

Although people do use the iridium BPR one on the 315 with reported success so it doesn't foul the piston on this engine. Quote Link to comment Share on other sites More sharing options...
serious3 Posted February 6, 2010 Author Report Share Posted February 6, 2010 so is the iridium BPR the same length as the std BPR one then? i'm confused now as my local bike shop said the correct plug was the BPR not the BR..... Quote Link to comment Share on other sites More sharing options...
dond Posted February 7, 2010 Report Share Posted February 7, 2010 I use the BP plugs in all the trials bikes and I have not found one yet that has clearance problems. I have a shop and work on them all. The projected nose seems to work well. the idea is that at low revs it will stay hotter (less fouling) and will not be as hot when there is lots of flow to cool it (high revs).

serious3 Posted February 7, 2010 Author Report Share Posted February 7, 2010 think i'll chance it in mine and see how i get i on will update later after i get back from practising! Quote Link to comment Share on other sites More sharing options...
serious3 Posted February 7, 2010 Author Report Share Posted February 7, 2010 looked to be about 3mm difference in the length so i threw it in and off it went. no problems at all apart from it ran better as the old plug was shot. so you can get away with the "p" type plugs in a 315r! roll on next week when my iridium one arrives! thanks for the replies lads.
