1St Valve Check After 90,000 Km/18 Years On 4Th Gen

Gave my redslut in the hands of a friendly mechanic to do some work on her.

The carbs were going to be taken off and cleaned (also for the 1st time since new), so checking the valves would be logical..........

and the scores are

Rear cylinders....

One intake out of range so all were set to 16...

Thank you Mister Honda for designing and building the VFR engine!!!

Amazing, does it feel any different since having those few adjusted?  I'm contemplating doing mine but I only have 24000 miles on the clock!!

Interesting that you had a couple that were loose. I had to adjust 5 (?) at the 150K km mark. I did checks every 25K until 100K. All were in spec but trending tighter. I figure I won't have to do another valve check again.

Trending tighter is what you expect due to the design of the shims setup

One of the reasons valve's get loose is build up of coal deposits on the valve. Mostly steen on bikes owned by slow drivers

Ugh, Dutchy you need to either ceramic coat those headers or get some stainless steel ones. Redslut deserves no less!

So ride slow for a while to loosen them, and then ride fast to tighten them. Self-adjusting valves!

Sadly, mine look like that too. 

I just did mine at 28000km.

3 of 4 of the front cylinder intakes were too tight, around 0.10 to 0.11 mm.

Pulled the cam today and adjusted the shims.

now adjusted to close to 0.16mm.

All other valves were fine, the exhausts were all 0.26-0.28mm.

Dutchy, I think your in is out on the first table.

I know the mechanic Dutchy went to, he's a perfectionist, who does nog make that kind of error.

It's amazing what a little exhaust wrap will do  :491:

That's a thought, but doesn't it hold the moisture in and rust the pipes too? At least that's what I've read. What's your experience been?

Been looking at getting my headers ceramic coated by this firm in the UK  -  http://www.zircotec....ke_exhausts/155. Although i have a new Motad s/s system its already looking "worn".Heres the reply i had

Dear Adrian

Thank you for your recent e-mail enquiry.

Tougher than the standard automotive coatings, Zircotec’s new Endurance Range™ has been specifically formulated to provide motorcycle riders with a durable novel surface finish that minimises rust on exhaust systems. The new coatings also offer Zircotec’s specialist thermal barrier technology, insulating heat within the exhaust preventing it from spreading to sensitive areas of the bike, whilst lowering surface temperatures to assist in reducing the risk of burns for riders and pillion passengers.

As a derivative of our proven and popular automotive Performance Range™, the new smoother coatings are applied using Zircotec’s proprietary plasma-sprayed process to deliver a well-adhered thermal barrier that outlasts conventional OEM and aftermarket paints.

The net result is a range of coatings that present motorcycle riders with a new form of low-maintenance customisation that also prevents components and accessories, such as panniers, from heat soak and damage.  Thousands of miles of rigorous real-world testing across Europe, exposed Endurance Range™ equipped bikes to mud, rain and tough terrain; yet the coatings emerged with no unsightly chips, flaking or abrasions. A quick power wash removed any mud caked on the bikes and brought the coatings back to their original appearance.

The new Endurance Range™ is available in 3 colours:

Endurance Black (matt black finish)

Endurance Metallic Black™ (incorporates a metallic fleck)

Endurance Graphite™ (attractive grey finish)

Regarding pricing; For a set of VFR800 headers plus collector, the cost to coat will be £210 for any from our Endurance ™range. Prices exclude shipping and VAT.  Turnaround time is approximately 15 working days with payment accepted via credit card or bank transfer.

Our coatings are only applied to the external surfaces of the exhaust system and are covered by our 3 year guarantee.

To proceed, simply send the system to the address below, remembering to include your contact details. We automatically mask off machined/ flange surfaces to protect them from coating. Please ensure that all other areas that do not require coating

including badges and slip joints are marked or taped off before sending the parts to us. (Please note that, although we take extreme care when masking off badges to protect them from coating, there is a slight risk of damage to some painted metal badges when going through our process.)

We will contact you upon receipt to confirm details and arrange payment.

Please contact me if I can be of any further assistance.

Kind regards

Peter
