which coils??

[seadog]

having a bit of a problem with my r60/5 in that when i get into 4th and the engine gets warm, she will lose power even when revving, now i have checked my fuel delivery and made sure i dont have a vacuum in the tank so i would like to change coils and HT leads, but, being a novice at this when i took the tank off and had a look i have two coils which are slightly different sizes to each other but when i look at motobins website at coils for this make/year they are all the same size!, stupid question probably but does this make a difference?

thanks in advance

i take it the question was too stupid for the experts to answer.?

You'll need to wait for Proff for chapter & verse .

It sounds to me (knowing very little about the R60/5) that someone has swapped a coil in the past and has fitted a slightly different model.

I can't believe they should be different .

If no-one else replies, I'd go for the Motobins option .

What happens if you change down to 3rd? why do you think it is coil related?

Both coils are meant to be the same so my guess that during the last 40 years or so, one of them has been changed. I seem to remember but stand to be corrected that the originals are 6v coils connected in series and that a common mod is to replace both coils with a 12v twin output one

Could be talking complete bollix as its late and

not 100% sure its coil related but thought i would change them as 1 of the numerous things it could be!!!, the problem doesnt seem to happen until the engine is warm, and in higher revs, but one it happens i can go down through the gears, and the problem is still there, until i have stopped for a few seconds.!!!

i have checked fuel supply so electrics were my next thing!

had the same problem with an r80 rt I picked up turned out to be either float bowl level, the r80 should have 21/ 22 mm of petrol in them, dont know what yours should be I had 15mm in one and 25 in tother, the other thing was a sticking throttle body up inside the top of the dome on the carb, gave me the same probbs you are having worth checking before ya spend owt
