Title: Pulls Like a locomotive untill 6.000 rpm
Post by: Enfield on May 02, 2018, 03:19:43 PM
Hi.
 Finally I have my K approved and licenseplate on....and summer is close!
But... It rund Great - starts right away, idle is Calm and it pulls really Well , untill it reach 6.000 rpm or roughly 60 mph in 5’th.... then there is no more.... I can’t even make it go higher when doing a long run?
 I have changed fuelfilter and all hoses. Added new ignition cables, plugs etc. Cleaned all connections ( but might go over Them again)
 Things I havent done yet is balancing inlet, and checked ignition ( it goes Real smooth untill 6.000)
 Awaiting arrival of Morgan carbtune - but Can unbalance cause these symptoms?
 My hope was that someone experienced similar and solved it.
Intake rubbers/manifolds also new!
Regards
Chr

60 mph in 5th is unacceptable... stop it now... you need to keep it on the redline...

I would keep it on the redline if I could.... It is pure gasoline...and injectorcleaner in the tank - have run 1 big bottle through the system...Stp ( http://www.stp.com/products/fuel-additives/super-concentrated-fuel-injector-cleaner)
As we cant get Techron around here

Is one of your intake rubber clamps interfering with throttle action?

I Will check - but feel pretty sure that I have full throttle - checked it when I replaced the gascable!
Thanks

Is this the cafe bike (you have two, a plain and rs in your signature) ?


Could it be the after market instruments acting as rev limiter?

6.000 rpm or roughly 60 mph in 5’th
Should be closer to 4000 rpm at 60 mph in 5th  :dunno

greetings..

he said 6000rpm or roughly 60mph in 5’th... not 6000 rpm in 5th gear...

if he meant to say 60mph at 6000rpm in 5th gear he better order a clutch kit...

I have the Bep 3.0 mounted - it was the same before I connected the instrument.
It is the Rs in my signature that has been rebuild.
 Clutch is ok :-) probably the readings on the instrument that is incorrect.  I Can follow normal highway speed and then no more.
 Never been driving a K before this - but assume that there should be something left ;-)
 My first thought was also techron or similar - as it have been sitting for a while. I Will give it a bottle more when I fill it up.

You were partly right!! Got a wrong gascable... when I fitted it I assumed i should take up the slack in the handle... found out it then only goes 1/2 of what it is supposed to
🤥 just never driven a K before so I thought it was normal with that little movement in the handle[emoji49]

Holy sh..   nothing wrong with that one ....
Shortened the gas cable about 2 cm with a cable repair kit.
 Now it just keeps pulling[emoji48]
