Cleaned fuel tank, fuel lines, installed fuel filter, cleaned twice carb, checked compression, replaced spark plug, replaced CDI, checked CDI sensor on flyw...

Re: Need help, NE50-AF05 BBK tunning.

Hi Everyone, :b2t: Need your help, Im decided to try a good Malossi BBK (or any other good manufacturer) on my NE50 engine AF05E (Honda Vision 86-90 in Europe). The BBK installed gives me a lot of power but a lot of tunning problems (auto-ignition when hot is allways present). What's the best BBK si...

Coastal road, see Google "Sao Pedro de Moel" / Portugal.
This is where I test my "machines", I don't let me distract by the nice view :bump: .

Hi everybody, Excellent news, my problem is solved :thumbwink: . Cylinder head was re-surfaced and polished inside. No more auto ignition and on flat road with no wind it reaches easily 70Kmh (I didn't push it more as it was the 1st ride). :worship: Thanks to all the help kindly provided by you (mai...

Re: Need help, AF05E engine with 46mm BBK, no power.

Hi 1man8scoots, Pre-ignition is one thing (air-fuel ignition takes place before the correct timing) and auto-ignition/self-ignition is another. What I've is the 2nd, the engine runs even without CDI electrical power :crazy: . Carb was checked and re-checked. Regards and thanks for yr. help. Pre igni...

Re: Need help, AF05E engine with 46mm BBK, no power.

Hi, Made my road tests today, trans is working fine/marvel, T┬║ values are normal ~300┬║F after 5Km. But the engine enters into auto-ignition when hot and running at full throttle (65 Kmh), if I disconnect the ignition with the key, it continues running with less power and out of timing. Is this a s...

Re: Need help, AF05E engine with 46mm BBK, no power.

Thanks you all for the good advices, I'll continue with a T┬║ gauge and check trans dynamically without cover .
What's the head t┬║ range and where/how is the t┬║ sender fixed to the head? Are there any pics in the forum?
After all this I'll become a Spree specialist :thumbwink:
Kind regards

Re: Need help, AF05E engine with 46mm BBK, no power.

Yesterday made my road test with 6.2 gr variator rollers and 1% oil in tank. I've got more rev's at medium speed and less power at low speed.
But my main problem remains, no power with warm engine (after 5 KM), it seems a bad ignition timing :crazy:

Re: How old is everyone?

We could make a "chi-chat corner" for those near 60 (I've already counted 6). But remember: The time to begin most things is ten years ago. 59 now, but it seems like I was 25 just a little while ago. Time flies when you're having fun. Time flies like an arrow, fruit flies like a banana.

Re: Need help, AF05E engine with 46mm BBK, no power.

Hi Graphite,

The engine oil is 2T Sunoco 1/2 synthetic, the plug thread on the pics has copper grease.

Re: Need help, AF05E engine with 46mm BBK, no power.

Thanks Wheelman a lot for the professional advices: 1) Of course and logic, 20% increase in bore needs more oil. I'll add 1% 2T oil in the tank. 2) I've ordered the 6.5 gr rollers, I'll let you know the result. 3) 100KPH :nervous: :coolcruise: It's far above my goal of 80KPH, and at that speed you n...
