Andy1976:
Hi Den, I got the bike in September last year. It was running lovely and it rode nice too. There was'nt much history with the bike, just a couple of reciepts for a new battery and brake pads and an MOT slip. I have had it re-bored and new pistons fitted(it broke down six months ago).
      When you say valve clearances, do you mean the gap between the tappets? The HT leads seem ok but I've noticed a chunk missing from no.2 plug cap. The plugs are NGK DR8ES and D8EA (only jus noticed two different types!)
     I have taken off the carbs to give them a good clean. I have found a good reference on the other site which should help with settings.
         Thanks mate

Spitfire:
Yep, valve clearance, tappets, 2 inlet 3 exhaust if I remember correctly, the other site should have loads of info that you can use, sure helped me rebuild my F1.

Cheers

Den

Andy1976:
I'm going to re place the spark plugs as the others were mis matched. Two were D8EA and the other two were DR8ES-L(NGK). The manual says to use D8ES(NGK) or X-24ES (Nippon Denso). What plug would you recommend I use?

Thanks

Andy.

Dave M:
I've always used NGK's.

Spitfire:
That's a good question, I always used NGK D8ES-L, but they you can't get them anymore, so I got D8ES-L R, these did not work they fouled up very quickly, so I tried D8EA,s, these were better but still fouled. Then I read a thread on the other site in which Hondaman recommended the ND X-24ES-U, I now use these and they appear to be fine.

Cheers

Den
