Re: spark plug caps

I've had problems with the "R" plugs so now only use C8's .Seems better with Lucas coils (instead of the Yamaha originals) , copper core HT leads ,5 Ohm plug caps ,and C8 plugs .

Re: spark plug caps

My 10 Ohm plug caps arrived today .Fitted them and what a difference BLOODY AWFUL !!!!.Sod to start then backfired, sounded flat ,exhaust headers glowing red .Re-fitted the 5 Ohm plug caps and all OK !! I'm amazed a plug cap can make such a difference .Ho Hum ,we live and learn .

Thanks , Ordered a pair from France (£13.35 inc P&P).Still wondering about the advantage of 10 ohm v 5 ohm. Come on you electrical boffins , i hate a mystery .

spark plug caps

I am using a "minimag" ignition system on my interpol and have been advised to use 10 ohm resister plug caps. I ordered two but when they came they were 5 ohm . Phoned the bloke up and "nah , mate don't exist "!!!. I've seen them "on-line" but not the long straight ones...

Interpol starting .

I've got an irritating problem with a aircooled rotary Interpol. It runs very well BUT after stopping and turning the engine off (stopping for petrol , cuppa tea , or any other reason) there seems to be a 50/50 chance of it firing up on two rotors !!! It seems to be the r/h rotor not starting usuall...

Re: S.U Carb jetting

They are stainless steel and a lovely colour from straw brown tapering away to polished stainless at the reverse cone end .The colour is exactly the same both sides so I guess the rotors mixture/balance is good. Very Happy .A sort of external/visual colour tune !!!!!

Interpol 'will not start when hot

I've sonic cleaned the SU's and i'm fairly sure they are pretty close to a std setting . The engine starts o.k from cold and warms up .It settles to a good even tick over but if I stop the engine I've got no chance of it re-starting .The carbs were cleaned for this reason .I have the digital system ...

Re: airhead thermocouple wiring

It seems the earlier post regarding the fact that the thermocouple gauge is wired directly to the sender is correct .All cleaver stuff !! (witchcraft ).Two dis similar metals ,the sender ,when heated produce a micro voltage which moves the gauge .I guess a solar panel works in a similar way ????
