Honda-SOHC

Probably my last visit for a long while. Best of luck with the forum and many thanks to all those who have helped me with my 550F2 restoration.

I’ve attached my plans for the forthcoming 6 months. If you feel you can support UNiCEF it would be gratefully received.

Best regards

Phil

Just for you, Ted.

I don’t believe it. Roo was kind enough to source me two new fully intact tank badges from the states.

Unfortunately they appear to be for a 500, not a 550F2.

£25 plus postage if your interested.

Now Roo.

Slight technical problem.

Spot the difference?

Just thought I’d share my experience with an issue on my recently restored 500 four.

Although I’ve owned the bike for a year or so, I’d not really ridden it seriously….just a quick trip round the block. I’m preparing the machine for sale and was intent on ensuring the bike ran perfectly. I’d noticed that the bike was fine on choke, but wouldn’t idle correctly and responded poorly to blipping the throttle, noticeably hanging and failing to settle properly. Naturally I suspected the idle circuits. I’d previously checked all other influencing items such as leaks, timing valve gaps etc, etc.

I removed the idle jets (#40) soaked them in STP carb cleaner and blew them out with an air line. Interestingly I also aerosoled the jets and it was clear they were passing cleaner under pressure. I reassembled, but the situation was the same. I dismantled once more and this time viewed the jet through a bright back light. I could see clearly what appeared to be a translucent, spiders web type structure that would not allow a .4mm wire probe to pass through .

In an attempt to clear the hole, I heated the jets then plunged them in cold water. I prepared the wire probe by cutting it with pliers to create a small cutting edge, inserted the wire and rotated until the wire passed through, then blasted again with aerosol cleaner.

Result: impeccable tickover and throttle response….

I was nervous about passing wire through the jet, but it clearly had the desired effect and removed the obstruction. All four idle jets were affected identically in the same way.

Just thought my experience might help others on this forum. If you use this method, ensure you use a wire gauge slightly smaller than the jet drilling size. I used .4mm on a #40 jet and it worked just fine. But it might pay to break up the obstruction with a .38mm in. #40 jet….who knows.

Apologies in advance….

On the 17th June I’ll be participating in the annual C2C fund raising Coast to Coast charity bike ride for the Marie Curie Charity. C2C is an independent charity run by volunteers who sacrifice their precious time to organise this annual event. It’s continued success is very much reliant on the generosity of participants and the charity contributors – yourselves.
 
The ride is approximately 155 miles, riding East to West from Grange Over Sands to Cote de Scarborough. The ride is mainly ‘off road’, which to a novice and physically compromised  ‘off road’ cycling antiquity like myself should prove to be challenging. Fortunately I will be accompanied by my 13 year old Grandson, who will no doubt show me the ropes and keep me safe. For those of you who don’t know me, I was involved in a serious cycling accident in 2019 and it’s taken some time to get back on two wheels. This ride will mark the 3rd anniversary of the accident and those who are familiar with my cycling skills will be confident I’m unlikely to complete the ride without incident!
