CFMoto's 650's

Hi ....

I haven't visited for a while but I am giving my cf650tk a 60,000km service and plan to check the valve clearances.

The problem I have does anyone know what the clearance should be ...in the 2014 service manual for CF650-2 give the clearance in the periodic maintenance section P2-19 as EX 0.22-0.31mm IN 0.15-0.21mm BUT in the Engine Top end section P5-6 Tech specifications shows the Valve clearance as EX 0.20-0.26mm & IN 0.08-0.13mm.

Checking a service manual for a Kawaski ER6 shows the first figures in both sections.

I haven't removed the cams yet but a quick check shows that I need to adjust the clearances and I believe that the shimming arrangements are different. I am a little unsure what the clearances should be as the manual seems to be a copy of the Kawasaki in most parts so may not reflect what they should be!

Regards and safe riding to all ...

Exhaust: 0.22~0.31 mm (0.0087~0.0122 in.)Intake:0.15~0.21 mm (0.0059~0.0083 in.) is correct according to the mechanic here.

Hi ..... I was quoted different figures from the Australian Distributor these being Exhaust:0.22~0.28mm Inlet:0.08~0.13mm.

Hi all ...

As a followup to my previous message I went ahead and checked the value clearances using the figures quoted by the Australian Distributor.

Using their figures I had to change some Exhaust bucket shims with my clearances in the ranges as follows: Exhaust (all)0.24mm Inlet:0.10~0.11mm.

The figures quoted in the CFmoto service manual Periodic Maintenance section 2, quote Exhaust:0.22~0.31 Inlet:0.15~0.21mm but in their Valve adjustment Clearance Charts show the following as
"specified Clearance/No change required" Exhaust:0.20~0.26 Inlet:0.08~0.13.

Interesting I know but it would be nice if we knew what the manufactures design/assembly/service clearances are.

maybe the above may help someone.

Regards ....

Hi.

My first post on here.

I've just purchased a 2015 CM MOTO 650tr. It was actually the support bike in the Isle of man TT races in 2015 when CF moto came fourth in their category. It's only done 800 miles. Just wondering if it will have the mechanical throttle body restriction with being a UK model. Thanks

Hi Stephen ....

I didn't think the UK version of the 650 tourer or naked were sold restricted as they are here in Australia (the CF650TK).
So I would say No to your bike being restricted.

As said...Phil's Tr is restricted....(he says/thinks?) The only one I know of in the seven or so Tr,s that I know of.

Thanks guys.

Hi Tweet.
Did you say the guy that I bought my CF Moto off is a member on here? Not happy with him as the bike has several issues with it. I've tried discussing with him to see if he will pay towards getting them fixed as they were deffinately per existing faults and he's basically blocked me. Please pass on my message if you can. Or could you let me know his user name so that I can.
Many thanks

Hi Stephen.

I'm not sure any of us that know each other as a group, actually know anybody who has been riding the TT support bike. It's a shame you've got problems, as, once whatever your problems are are sorted, you'll have yourself a good bike there..

Its a nice looking bike. Just not happy that he never mentioned these issues on his add or told me about them. I had it transported due to the long distance. Now he's blocked me so can't resolve the matter. Not very decent of him as he knew I was going to use it as an emergency blood bike. But it's off the road toll I can get the issues fixed

Sorry to hear that, so, out of interest what are the issues?

Hi. Yes. My CF Moto 650 TR 2015 plate. Has fault codes 47 & 48 oxygen sensor 1 & 2. Used the sequence to re-set them but they recur. Is this a common fault with them? Could it be a false reading? As the bike has only done 800 miles but had been in dry storage for 3 years assume started on occasion. Will it harm the engine running it with these fault codes?

Thanks in advance.

Oh yes and if they actually do need replacing. Where is best place to buy? Tried ebay but next to none come up and most from Australia. I'm based in the UK and the bike is a UK model

Many thanks

I wouldn't assume the bike has been regularly started, you could try cleaning them, afterall, if you're going to replace them, nothing to lose, and you could add some redex or similar, and run it through. It could just be a case of the bike having been stood for so long, and, cruddy petrol making it's way through. Could also possibly bypass the lambda sensors, using a Oxygen Lambda O2 Sensor Eliminator Kit, I'd imagine you can get what you'd need relatively easily.

Clean them by removing them, and soaking the sensor in petrol, at least overnight.

Thanks for your advice. That makes good sence due to long term storage and the fact it's done such little miles. Job for the weekend. Cheers 👍

Any joy??

No. Took them off soaked overnight in petrol. Scrubbed them carefully with a toothbrush. Let them dry. Assemble. Re-set the fault codes a d after 5 mins of riding both fault codes 47 & 48 came back on. Grrr

That's a bugger, you could always cap them off?

Surely that would still send same errors and would the bike not run at rich?

Hi

To be honest, I don't know, seems to be a relatively common fix on alot of bikes. Alternatively, you might get away with taking it for a long run. Mine had been instoarge for a couple of months, and I got the error 47 yesterday, but, good run on my commute to leicester with fresh petrol, appears to have cleared it. My front brake light switch appears to have given up the ghost now though, they're not keen on being stored, they are bikes that like to be used !!

Seems that way. I'm a blood biker so have done a good few hundred miles on it in the 2 weeks I've had it on the road, so will see how it goes. Hope you get your brake switch sorted

Yeah, brake switch just turned out to be a grubby connection, more down to the fact I'd ridden the bike up to where I was storing it in really manky weather, got covered in grit and so on, then I just left it locked up, wasn't expecting it to be stuck f in storage for 2 months !!. After it's clean, fresh fuel, and decent run it's settled back down again now.

Oh, good job you're not a blood biker in Coventry/Warwickshire, it appears a private company has taken what the blood bikers do

All good. Thats a shame. Probably a profit making company too

Yep, bound to be a profit making company

I think you will find that the Aussie CF's are downtuned.
