Misc / Open / Re: What Oil?
« on: May 03, 2015, 02:05:36 PM »
in the last set of questions,

 this item came out as the one.

http://www.eurocarparts.com/ecp/p/car-accessories/engine-oils-and-car-fluids/engineoils/10w40-engine-oil/?521776151&0&cc5_245



 the diesel version has a high pressure shear additive ,( I think)

 and pretty good for £17 for 5 ltrs

Thanks for the reply.

Do you have a link to the post in which it was discussed?

Was it considered to be OK with the integral clutch?

Misc / Open / What Oil?
« on: May 01, 2015, 09:53:24 AM »
What is the best oil to use with the engines as they have an integral gearbox and clutch?

Is it safe/good to use semi synthetic 10/40W oils that are specifically designed for car engines or do you really need to use 'motorcycle' specific oils or stick with a good old 20/50W?

Not looking for expensive/exotic oils just a good one for general use but there seems to many arguments about not using 'car' engine specific oils as the gearbox 'tears' it apart and possibly causing clutch slip, or is all this just marketing hype to get us to pay more for the same oil?

Thanks for the suggestions.

For home soda blasting I am assuming that you are referring the 'home' made kit using a tube into some baking soda and an air compressor? Unfortunately I don't have an air compressor.

Might give the TFR a try.

Anybody else have any other alternatives that they have found successful?

Other Bikes / Cleaning crank cases
« on: March 06, 2015, 05:40:06 PM »
I have the engine out of my Z900A4 whilst I am doing the restoration on the bike. Top end is off for guides, seals etc and as a result the barrels, head and cam cover have all been vapor blasted. Look a bit too dull and mat, but much cleaner than before.

However, the bottom end is fine and I am not going to split the cases just to have them cleaned. The A4's do not have painted cases, just natural alloy finish and whilst I have been over them with a small wire brush in a Dremel the cases still look very 'dirty' when compared to the top end as the finish is like a fine orange peel and as a result the dirt and grime trapped in the pockets does not get removed.

Any suggestions of how the clean the cases on the bench? Are there any chemical cleaners that can be used locally that can do the job or are there any solutions or processes that any member has used successfully?

The photo of the parts you have plated look very good but doing my own plating is not a route I really want to go. However, L & B have just quoted me £250 to primarily zinc plate my parts!!!!!!!!!!!

Need to get some other quotes as I can't believe that it really costs that much? They say that because it is re-plating all parts have to be wired, which I can appreciate but £250 just seems way over the top.

Thanks Julie

Unfortunately they do not do Zinc plating, which is about 95% of what I require being re-plated.

Apart from London and Brighton are there any other electroplates in the East Sussex/Kent area that members have used or would recommend to undertake Bright Zinc, Black Zinc and Chrome plating?

Thanks for the replies and advice.

I take it that you do not recommend masking off the the lower part of the piston area and vapor blasting the groove which is how the paint will probably be removed?

I am in the process of restoring a Kawasaki Z900A4. Both calipers need re-painting and on stripping I find that both have hardened brake fluid in the seal groove and also in the machined step where the dust seal securing ring sits at the front edge.

What is the best way to clean and remove these deposits? Is it safe to have them vapor cleaned?

Strangely, it seems that the carb kits seem to include everything except the the needle jet? Not sure what there is to wear on a main jet or air screw, which are included but they seem to supply a needle but no needle jet to go with it? Should they not be change at the same time as the jet is likely to wear?

Anybody had experience with the the piston rings from them?

Has anybody used parts from cruzinimage_uk and in particular their piston rings?

They are a fraction of the cost of UK purchased ones but are they any good and will they last more that a few miles?

Similarly, are the brake hose and carb kits they supply good? Again they are much cheaper than UK sourced items? Yes there will be 20% VAT to pay and a courier collection charge but they will still be cheaper.

Do we know if they are made in Japan or simply sourced from the Far East. Having said that do we know where UK bought parts are sourced/made unless we use Gen Honda parts which no doubt are also made in the Far East, but hopefully with better quality control?

Sprinta did it have the red line at the 70mph mark on the speedo?  ;D

Hi

Sorry, but I can't remember that detail  and I do not have any photos of the clocks.

I had a Planet Blue UK K2 in 74, so it is the correct colour, see attached.

Hi Phil

Like you I have just received my nice shiny new pipes from CMS and was considering exactly the same about trying to protect the inside. Thought I would try the Eastwood Hi-Temp internal exhaust coating available from Frost. http://www.frost.co.uk/eastwood-hi-temp-internal-exhaust-coating-with-extension-tube.html

I'll let you all know how I get on.

Kevin

Are the CMS downpipes double skinned like the original Honda ones were?

Cam cover screws, seat latch and battery carrier bolts were black plated so did the same.

The trays were from supermarket and quite handy for sorting.

How is the black finish done? What plating process is it?
