Loncin / CCM 230 Dual Sport Gearing
As I dont have a tacho on my bike and it seems to run low gearing I did a check this morning .
I removed the spark plug and wound the engine over to check how many revs for one rear wheel rotation , then checked tyre circumference by rolling it along the yard - end result is that at max power 8,500RPM I should be doing 72mph according to my maths .
Does that sound about right and what revs do you let your 230 engines go to ? - guess if 8500 is max power 9000rpm should be "safe" ....:riding:
Still running in so not been over 50mph but even that felt like a lot of revs but maybe it is in comparison with my 604 Rotax powered CCM ?
Re: Loncin / CCM 230 Dual Sport Gearing
My Ebay tacho shows I am running at 32 thou rpm so I cannot help! But I think that should be 8000 and that is enough, these are NOT racing machines with balanced this that and titanium this that and the other. They are cheaply made and assembled china-bikes.
I just wind up slowly til the 'over rev' kicks in and it splutters then I back off ten kph and cruise which gives me GPS 55 mph on a 200cc so you are doing OK
Why over rev? Don't you want it to last more than 6 months?
Re: Loncin / CCM 230 Dual Sport Gearing
I wont bother with a tacho off of Ebay then !
I have geared mine up one tooth on the front sprocket and was surprised how revvy it still felt - CCM claim a top speed of 72mph - not for long I suspect as you say Jape ........!
Trouble is in the UK every "young mum " in a family car has 100HP+ and needs to be somewhere else in a hurry - does not make for pleasant riding with a car 5ft from your rear and the driver applying make up !!
I use the small roads where I can but that is not always possible in the crowded UK .
I dont think I will be revving even to max power ,8500, as it feels "enough" at 50 mph , was interested to check that it was a "standard" ratio - still 125 gearbox ratios I suspect .

yeah, we all get that 'inadequate' feeling on our little bikes, and then we start looking at sports bikes and big thumpers and then we realise we would just be getting a whole new set of problems and dangers ... we all are waiting for a decent chinese 400cc. Shouldn't be long, this year will make or break the Chinese motorbike industry. or else we will all be out stealing yahama 450cc, spraying them matt black and putting chinese plastics and vin plates on them - what am i saying! ignore that.

What is the source of the 398cc water cooled engine on the CCM SR-400?
http://i784.photobucket.com/albums/y...S/CCM/bike.png
It shares specs with the Suzuki DR400’ s engine…

I think it's cool when they combine manufacturing sources…this bike looks to me to be sourced all or in part through Loncin.
not exactly the same....but very similar

Re: Loncin / CCM 230 Dual Sport Gearing
It is entirely possible that an engine purchased from Suzuki could be manufactured in China. You can be sure of one thing that the 400cc engine in the SR400 is not in violation of any existing intellectual property rights. CCM has the rights to sell the bikes but no rights to say…”it has a Suzuki engine” which may also include not having the rights to say “ that the engine is also made under license in a Chinese factory. The factory may also agree not to sell the engines they manufacturer under license to anyone but the owner of the rights…Suzuki.

Hey bojer..
I got the same problem with my galaxy xtr250 (same bike as Yours) i think??
If you look for chinaV's galaxy xtr thread he swapped out the standard gearing with a smaller chain 428, bigger front sprocket and smaller rear sprocket to get better road gearing on my bike, which helps a lot.. But without a balance shaft in the engine and the firm chassis it does vibrate quite a bit.. it still feels like it could pull a lot taller gearing too!!
I have a set of motox wheels with the 520 chain and gearing and i swap the 17 inch supermotard wheels and change to a 428 chain for road riding, i'll check the spocket size's next time i look.. unless chinaV or felix can remember.

Ok thanks for that - need to be a bit more patient and see what the bike is like once run in - mine seems to have a restrictor/slincer pushed into the airbox intake that reduces the size by 2/3 - that will come out and will try some jetting changes - got a 104 (!) main jet in at the minute and its very weak , will try a 120 as a big change !
The 400 CCMs do use the Austrailian spec Suzuki DRZ motors and the 650s the Suzuki DR650S engine - my 604 has the Rotax motor - dont make too much in the UK anymore .............

Yep , if I was not running in my little bike last night and was on my Ducati or 604 CCM I would have def hit the "young Mum" who pulled out in front of me apparently "not seeing me" despite looking right at me - 45mph has its advantages - 90mpg at the moment only being one of them !

Be careful, that 'restrictor' may be the opposite to what you think, some of those things act as venturi by design and that in fact SPEEDS UP the air intake. So if you take it out, don't break it and be prepared to put it back after frustrating weeks of fiddling with jets and carbie and never getting any improvement ....

It will speed up the air intake as it restricts the area available for the air to flow through but it looks like its there for air intake silencing , not a snorkel or anything like . Will take it out and see what happens , FWIW I am "mature" and have owned over 80 bikes so do have a vague idea of what I'm doing !:mwink:

Bojer is your bike a six speed or a five speed?

Only 5 unfortunately - 6 speed would be ideal giving the low gearing for the trails but less frantic revs on the road !

Well I am glad for you then, you can teach us as you go with a photo buildalong. :mwink:
Obviously if people don't put in their signature 'experienced, eighty bikes, vague idea' or 'newbie please help!' then we have to talk generally and offer what we do or do not know as help. These threads are not just for the original poster although of course that is the purpose immediately; over time they add up to a body of pertinent (and some times irrelevant but amusing) anecdote and experience for all who own or use these machines. Sometimes we even get people all over the planet acknowledge that it has helped them out when stuck or perplexed.

Re: Loncin / CCM 230 Dual Sport air box
Ok , short of time today but took the "restrictor" out of the airbox intake and fitted a 120 main jet - up from a 104 (!) - seems to run better now , not so sensitive to choke but only around the garden - will get it out on the road tomorrow and report back on its new rip snorting performance - or not ! :icon10:
Not expecting fantastic gains but bike was running very weak as standard , white plug and needing lots of use of the choke for the first couple of miles . Got a 115 ex Honda keihn jet to try if too rich but seems fine so far .........Attachment 3633Attachment 3634 Spot the difference !!
Re: Loncin / CCM 230 Dual Sport air box
OK been out today and bike is SO much better - difficult to be sure if its really much more power but the bike feels loads stronger and pulls better all through the revs . With a bit of a tweak of the pilot screw a 120 main jet seems about right , might go down to a 115 later but will get a few more miles on it first . Overall very pleased and a "must do" mod if you have a CCM230 or Loncin LX250 with the intake restrictor fitted .
Will post in maintenance/tuning for completeness too .
Re: Loncin / CCM 230 Dual Sport air box
Quick update , bike definitely goes much better with the mods. - will now pick up the front wheel just with a tweak of the throttle , wouldnt do that before . Was out yesterday on some trails and when we stopped for fuel I had done 90 miles but only got 3.5litres in before it was full !
Getting to enjoy this bike , off road its quick enough to surprise my frinds with their 600s and a 350 but still a bit slow on the road , have only done about 800km so still taking things gently .

What sort of fuel consumption are you guys getting ? - my CCM is almost scarily economical - keep thinking I have forgotten a fill up - just done 200km and only just squeezed 4.57litres in .......:eekers:
And that's having gone from a 104 to a 120 main too ............
