Rotary Owners' Club

Anyone know if there are any timing marks that facilitate the use of a strobe to check the timing on a running engine .

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 .

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 .

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...

When I rebuilt my carbs on an Interpol 2 I contacted Burlem fuel the SU parts suppliers they had no knowledge of the needles stamped qx51 so sent me what they said was a perfect match . Ha Ha ,nothing like .They would only travel half way through the main jet .Refitted the old qx51's .They are worki...

I've had grief with the NGK resistor (not racing , as I've heard folk say ) Trouble re-starting when the engine is hot .Pop old C8E's back in and fires up straight away .

Tried all the obvious ( swapping plugs ,leads ,caps, coils etc .) Engine moly'd and recently rebuilt by Startright. !!! This has me stumped .

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...

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. .A sort of external/visual colour tune !!!!!

Spoke to a bloke about a rolling road session .He said it could be difficult to get accurate readings due to the posifeed two stroke system on the rotary engine !!

I'm about to strip and clean the S.U's on my Interpol .The bike is running "OK" but as it's running through Commando "peashooter" pipes which are pretty much straight through and taking into consideration the poor quality of the fuel these days would anyone recommend any changes ...

I see the new rotor has re-appeared on fleabay !!!!. A lot of people seem to be extracting the urine ( last F1 minus engine at £14.500 )recently .

Hi , Where did you find a new rear sprocket oil seal ???

Hi , I'm taking my Interpol based café racer to the TT . I'm booked in for a couple of laps on the Jurby circuit . I'll be pleased to put my bike on the stand . Let me know the details .,Cheers ,Ned .

Yes me too !!!

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 ...

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 ????

Cheers , That's what the wiring diagram seems to indicate !! Works by itself !!! Witchcraft !!

Hi , Anyone know how to wire the thermocouple gauge and sender into the electrics ??? I've been re-wiring my café racer ( ex-RAF Interpol )All electrics working but I cannot work out the thermocouple / gauge wiring .Cheers ,Ned .

Get in touch with Graham at Startrights . ( www.startright.co.uk ).You can print one off from his website .

Does anyone have a right hand footrest / rear brake bracket they are willing to sell ?? The bike is a ex-RAF Interpol .Either PM me or phone/text 07881885090. Cheers .Ned .

Contact Startright 01132453643 They do an Aluminium replacement . Very easy repair .

Has anyone got a serviceable rear drive unit for an Interpol .Either pm me or phone/text on 07881885090 Cheers Ned .

Has anyone thought about or indeed fitted a modern solid state voltage regulator to an Interpol to replace the "sparkrite" unit ??

Hi , I am building a café racer out of an Interpol . I have put a pair of reverse cone Commando pipes on it and have the original silencers if you are interested in some sort of a deal .I assume the pipes you have are not the extractor type fitted to the works racers .Cheers Ned .

Norton Interpol parts on e-bay . might be of interest

Does anyone know if the splines on the Interpol gearchange lever are the same as any other bike ?? I am fitting rearsets and don't want to chop the std lever.Other bikes parts are disposable , Norton parts aren't !! Cheers .

Where ????? Looked but cannot find .

Hi , just read your post . i'll measure mine tonight .
