Hi, yes the forum link on the owners site has been removed, making it difficult to search problems and solutions for CCM bikes, there have been no offers since 2020 except servicing and 2024 is devoid of news and events, the site is hosted on CCM servers and it’s administrator John Drogan has been suggesting joining Facebook,
martinHi, from memory the fuel system runs at 3.1Bar. the housing bolted into the tank has a filter that helps separate out any air and a pressure regulator,relief valve.
I’m interested in your plan though.
martinHi, Andy
I’m uploading photos of flasher relay position on an original 150 (large 2pin relay and a photo of the closest thing to a Six wiring diagram.
martinHi, Ivan
The label on the Motol coolant says it will boil 135°C at 1.5bar , you can increase the boiling point by 3°C for every 1psi in the system, over 1atm and 100°C for water,
The radiator cap rating is 1.1bar (water would boil around 116°C and expand around 70ml) I measured Motul expansion at 40ml with 1.1bar, CCM like to leave a 150ml air gap in the top of the radiator (just covering the fins) so the cap never gets to do the job as it was intended and under braking the coolant in the top of the engine can displace the air in the radiator,
I have an expansion tank fitted (no air gap) and plan to investigate the thermostat for a 85-90°C running temp.
I hope some of the info has been useful,
regards martinHi, Ivan
have you looked at spark plug condition and checked for leaks on inlet and exhaust manifolds.
Coolant temp when riding normally should read around 68°C, standing still it can reach 93°C when the radiator fan comes on, the fan is controlled by the ECU reading a temp sensor on the rear of the cylinder barrel.
The CCM Spitfire engines were used in the Husqvarna 630 and SWM 650 with some updates, the engines are supplied to CCM by SWM with throttle bodies fitted, they are assembled into bikes and shipped out without the TPS setting ever being checked, unless CCM policies have changed since my Six made a two month long return to the factory and the TPS was said to be way out, setting can make a big difference.
you might find. sm26.gitlab. good for information, the TPS is actually called a MAQs it includes an air temp and pressure sensors, same part used by Mikuni on all its throttle bodies, ECU is same as Benelli 125tnt euro4, useful for wiring diagram info on ECU
martinHi, Ivan
short answer, what fuel are you using, have you changed fuel type, the recommend is unleaded 98ron ! most likely cause based on the bike running fine until now! exhaust manifolds can glow red, but if it’s abnormally hot it could point to incomplete fuel burning, as in the fuel is still burning when the exhaust valves open!
has the bike had its 550mls service, the oil needs changing to full synthetic and CCM mechanics normally carry out a number of adjustments, I’d suggest every CCM Spitfire owner has the TPS checked and set, CCM uses MAYA software,
martinHi Mon
Some early Spitfires had aluminium tanks, I think there are 21 of them , the rest use a nylon composite tank from Acabis, it looks as if something has got onto or under the paint, I’ve read these types of tanks are prone to paint bubbling, I think it referred to paint lifting off the tank surface, do CCM have an opinion on this.
martinPs. if this is the first CCM Spitfire the MOT station has on test , you may need to point out the location of the VIN number.
martinHi, bikes that have an MSVA test are limited by a 99db noise limit, that’s a bit louder than a type approved bike, (Spitfires also have no cats for the exhaust and no ABS brakes) so if the ministry man was happy with it ! I’d be more worried that the number plate is required to be positioned to the rear of the rear wheel as many CCM Spitfire owners opt for alternative fitments .
regards martinHi, you don’t have a photo, max upload size is 4mb , the sliding caliper with a side mounting bracket is used on a lot of models before the Spitfire, (different length brackets for different diameter discs), you can remove the wheel with the caliper on its mount (twist it out of the way as you remove the wheel) and remove the mounting bracket from the fork leg with the wheel removed
martinHi, early bikes with WP forks use a side mounting adaptor, later with Marzocchi or Ohlins forks use radial mount caliper with two large cap head bolts, I’ll add a photo, two mounting bolt cap heads have red pen mark to confirm torque setting. Rocker cover can be removed with tray in place, I’d suggest removing the fuel tank and tape on the rocker cover to avoid marking it (mainly against OBD bracket if fitted, as on some models), replacing cover I’d suggest extra hands to lift wiring for more room and care with the seal set into the cover, tiny hands an advantage getting to the cover and bolts, strong hands lifting the wiring loom.
martinHi, thought I’d post an update for the valve lifter, it looks like some of my original post has been deleted, (photos) CCM hosts and administers this site.
So, 4 months of using my bike and the starting problem hasn’t occurred since the valve lifter was modified.
the valve lifter assembly was a nice fit on the camshaft, a good sticky oil is the problem and I usually experienced the valve lifter not working when the bike had run the day before.
the camshaft cover and exhaust camshaft can be removed with the engine in the bike. the valve lifter works well when the oil is removed, so I checked that it opporated with a liberal coating of oil and tested that the spring loaded plunger could lift the offset weight in a vertically position to reset the valve lifter position, I added 0.1mm of clearance to the valve lifter assembly, I removed 0.03mm cleaning up the surface of the circlip and 0.07mm from the thickness of the washer, (horizontal movement of weight is much easier than vertical) when in the engine it opporates horizontally and returns the valve lifter to the starting (decompression ) position when the engine stops,
I’m adding photos to this post again.

I thought this subject would be of interest to many, as my bike spent 2 months back at CCM’s factory and had a further visit by a mobile tech without the bikes issues being resolved.Hi, I looked up “Completely Motorbikes”, there are more locations than CCM have curantly listed, I’m guessing as more of the group come on board we’ll have more options, link below
