Clunking at low RPM.
 
Hi Guys,

I have 2 issues. My 660 R has 29K km's on now, when I try and accelerate from low RPM it clunks but if I kick down one it pulls smoothly. I have heard of issues with the primary nut, but that seems to be a problem even in neutral which is not the case here. I have checked the cush rubbers and they fine.

The other problem I have is just occasionally it will stall for no apparent reason, hit the starter it fires up immediately? The idle seems quite low could that be a problem?

Thanks,

Smoky

Mine clunks a little when it goes into first,so does my mates. Most bikes do imho.

Clutch adjusted ok ?

You may have already checked this but is the chain properly adjusted and clean/lubed/

Sounds like your idle speeds a little low..14.5-1500 rpm is generally considered best.

how to adjust the rpm is within the site

If I'm reading your post right......

To lower revs & to higher gear big singles don't like it.
they have heaps of torque but are not a flexable motor..
My TTR250 will pull from just over idle in top not fast but it
dose it with out complaint.. try that on a big single & they
***** & complain like school girl... DR650 & KLR650 are the same...
