Thanks my friends, I'll check that !!

Well, thanks for asking :-) The fuel pump stopped working, so I was unable to test the cvt by hoisting the rear end of the bike upp and see what happens when I turn the throttle off. A new pump costed about 200 €, so I thought I'd buy one next spring - can't ride here in mid-Sweden anyway, we have s...

As if the cvt-trouble was not enough, the fuel injection pump broke down some days ago. So now I can do no test before the sparepart arrives.
Think I'll re-name the bike and call her mrs Murphy...

Yes I was surprised at the wear of the sliding faces. But - they may have been there before I got the bike...back then the pulleys were not in line, and I know the builder/previous owner had to buy a new belt, due to that, suppose he lost interest then...well anyway that could be some old marks. I'l...

Here is the whole bike.

Here, some photos, hope they are not too large :-/ Yes, I found a product sheet of the cvt in the engine manual. It said it was a Comet 30. From there I also noticed the bronze bushing was missing. I think the belt sticks to the axle when I let go of the throttle, and that is causing the too fast ge...

It appears there is at least one part missing from the cvt-drive, and that is a bronze bushing that is supposed to be in the primary drive. Now the belt is touching the driving axle, and I can imagine that is the problem. I'll see if I can find one bronze bushing, aply it and see what's happening. T...

The cvt is brand new, so is the engine. Bought from shops in Holland. BUT there is no spring in the front pulley. I remember I was a bit surprised when I took the thing apart last time. :evil: Maybe it is still in Holland... :shock: Hopefully, this is where to problem is. No photos today either, it ...

Well, what happened then ?

Hi guys ! sh*t, I did not get the time to tear the cvt apart today - too busy earning my living :oops: I'll try again tomorrow. @gilburton - when giving the bike full throttle, it moves with a slight hesitation at first, then pulls strongly until it reaches top speed (90 km/h). The acceleration feel...

Ok, I'll take it down to parts tomorrow and take some pics

There are no weights in the primary pulley. And the secondary must be ok, since it is just following the primary, and if it would get stuck in "high gear", there would be no braking effect when the rpms are decreased. Or am I wrong ? It is not the chain grinding at the secondary pulley, it...

Okay guys, ther neverending story goes on :wink: Now I have spare belts (two of them :lol: ) , the primary and the secondary drive discs are in line - but I still have the bloody same problem - when turning down the gas, even moderately, the back wheel starts to brake and the bike is truly difficult...

Well, so far I had lots of troubles with my health (artrosis and hip-replacements) but now everything looks better ("Always look at the bright side of life..." ) I managed to get my hands on this (Dutchbuilt) Honda Rebel 250 from 1987 with a 418cc diesel allready in place in the frame. Now...

Thanks, gilburton !

It was useful, thanks a lot !

I have been told by an expert, that diesels are not sensitive to the airflow like forstroke petrol engines. But they are sensitive to dust, so it is important to have a good airfilter, he recommended me and oiled mc-filter.

Well, I managed to make a spacer and move the front disc 6mm out. Now the discs are in line, and hopefully this will work. Now, the only trouble seem to be to find a belt...I thought Comet 30 was a very common cvt ? But here about - no belts

Oh, no answers...?? I thought you guys knew everything

Congratulations, the first testrun is a nice milepole to reach ! Especially if all works well Looking forward to some photos

No, it doesn't
But thanks a lot, it was really a good tip what you wrote about keeping the oildrops from the chain apart from the discs !
I really appreciate that

So - is it not possible to move the front sprocket out 5 - 6 mm with a spacer ??

Well today the problem solved itself. I went for a ride in the wonderful weather, and thought well today I'll try the top speed. Lo and behold - 90 km/h :mrgreen: But in a long uphill there was a funny buzzing sound, and the bike lost the drive, but engine was running smoothly. sh*t, I thought, must...

Good tip, thanks ! The chap who sold it claimed it does 90 kmh, time will tell....

Another picture...
No. Unable to load a picture, even if it is small

Thanks gilburton, that was good advice :wink: I intend to do what you suggest 8) The bike is a 418cc (China-made) diesel in a Honda CMX Rebel (former 250cc) frame. Found it when I randomly surfed on the net on a Dutch site, Autoscout or something like that. Called my Dutch friend Ruud and asked him ...

..... I'm not sure of your throttle linkage but possibly you could put a longer actuating lever on it which would give more movement at the twistgrip?? Or maybe a secondary lever linked to the original lever in such a way as to give more movement? Yes, that is what I think I have to do. Thanks for ...

THANKS a lot !
