Best Spark Plugs for 750 GT and what is the gap?

[Brett64]

Hi,
This has probably been answered but having just received my 1970 750 GT the other day I have been busy getting her ready for the road, but I am looking to change the plugs, the current ones in are NGK B7ES, but having recently read a manual they recommend the NGK B9ES but no gap has been recommended. Also I can not seem to find the spark plug anywhere.

I have replaced the fork seals and re-lubed the bearings, replaced tyres, tubes and am waiting on some parts and rubbers from Andy Wagner. I am also waiting on the tank and side covers to come back from the painter, but should hope to have her on the road by the end of the month.

Thanks

Brett

Brett , 7,s in a gt are a bit Hot    maybe the Po was trying to mask something ??

Try 8/9,s with a gap of .030 . See how she likes it

BP8ES for the "small" heads (S/SF/GT)
B8ES  for the "big" heads (SF1 etc.)
Gap= 0,8mm

See http://www.ngk.de/nc/en/product-finder/produktfinder/MOTORRAEDER/ZUENDKERZEN/LAVERDA/750%2520%2520GS%2520GT%2520S%2520SFC%2520SF-2D/BP8ES/7616/

NGK B8E S ? Gap at .7mm or .028?.

At least that's what I use in my 71/72 SF and have had great results.

Thanks guys I thought that 7ES would be to hot so I was thinking of the 9ES and getting the gap is helpful. I might try the 8 as well, she did start easily with no smoke and sounded strong but the real test will be a ride once I get her back together.

Thanks
