One for the [email protected] Heads.. the 1340 ?

I really should know better than to ask..but..

I've a friend who has a notion for one of the Big-Twin engined cruisers - possibly a Road-King. Tried to put him off - but not too hard - as I like the RK ones myself.

Issue is the engine(s). There's a few older 1340 engined ones around for sale.

I had one of the Evo 1340 lumps in a Dynaglide a while back. Torque aplenty, and (apart from a crappy aftermarket alarm) ultra reliable. Couldn't live with it long-term though as there was an awful engine resonance that kicked in around 3800 rpm / 60 mph ish which got to be unbearable. Easy to ride through it, or short-shift to avoid it - and it was actually a smooth running thing everywhere else, but not right smack in the middle of the rpm range where you wanted to cruise the damn thing at.

Killed the enjoyment of the bike completely for me in the end. Tried a load of fixes, but to no avail. Sold it on eventually - let somebody else fight the good fight.

Question for ye - are all the 1340s like that ? Do you need to go for one of the later 1450 or bigger twin-cam models, or was I just unlucky with that particular engine/frame combination ?

Is it got that bad that people can't even admit to showing an interest in the harley fegussons, that the old "I've a friend who" is called upon (wouldn't blame you mind!)....

Re: One for the [email protected] Heads.. the 1340 ?

driven both no problem, vibes are present but not to that extent, id say you were unlucky, maybe engine mounts gone or something, later 1450 is a bloody good engine, just avoid ones that are overtuned, can fuck em up easy enough, stage one is fine, its just a mild upgrade. 1340 has a lot of loyal fans so its not to be avoided by any means.
my yoke has the 1450 and never given any probs, been in england scotland,france italy no bother atall.

Thanks Allsorts.

I spent a fortune trying a range of fixes - even fitted an upgraded (read bloody expensive) engine mount from a UK company, that was supposed to sort the vibes, but no joy.

Did a bit of reading on the later 1450 then and discovered that amongst other things it was fitted with balancer shafts - which the 1340 wasn't.Always had a suspicion that the vibes were part and parcel of the 1340, but maybe perhaps just worse in the Dyna chassis.

I think an exploratory run on one or other out at the big shop might be worth a shot, see what the state of play is, if they have any older 1340/1450s around.

Well i couldnt knock the 1450 in fairness, i have it over twelve years now and cant see me selling it tbh, ive ridden 1340s and never took too much notice of bad vibes so maybe it was the dyna chassis with the 1340 that was the prob, well worth trying one , roadking would be very different than dyna anyway. Good luck to yer mate whatever he goes for.

If they've fitted balancer shafts, that suggest to me that they were fixing an issue with vibrations, so what you were experiencing was likely normal.

I'm not really after a cruiser Burt, but as an aside, did get a run on a demo model Scout at the dealers here about a year ago. At the risk of sounding stupid - I found it just a little too smooth, and far too easy to ride.

Felt like a Viagra or other very sanitised Japanese take on a cruiser, rather than the poorly designed overweight bad-handling loctite everything down or lose it type yokes that are a bit of craic and keep these boys on here so entertained

That's kind of where I'd got to. Thinking back, I suspect it was where the engine's vibes around that couple of hundred rpm band unfortunately matched up with one of the natural harmonic frequencies of that particular chassis/pile of bits - and the whole thing went into pneumatic drill mode. Don't think it could have been a widespread issue, or it would have been all over the forums (or the non fan-boy ones at least).

Certainly taught me a lesson about test-riding a bike properly before you buy it

I've got both the evo and twin cam. If i was to pick between them for long distance touring i would go with the twin cam as long as ya keep an eye on the cam tensioners. I updated mine at 25k even tho it was okay. I have an evo wide glide and it is a vibey bike but it's still one of my favorite bikes and I will never get rid of it.
