Reed block spacer gaskets ?

[grahamboard]

Hi please help, I have just bought some reed block spacers and need to know if I need to put gaskets either side of it? Rd350lc with YPVS engine fitted. Any help great.

You can add gaskets or not but it is worth considering that any leaks can cause the mixture to lean out and destroy your motor so govern yourself accordingly.

Thanks for your reply, where is the best place to buy some gaskets ? Don't seem to be any on eBay.

Hi,
I am putting genuine Yam gaskets each side of mine. Try Granbys 0115 944 1346, as they normally have them in stock for next day delivery.

If you get stuck make your own get some gasket paper from any motor factors & a 6mm hole punch, if your unsure read last months practical sportsbikes. Been making my own for years

Would silicone as a gasket be ok?

[nikfubar]

If your gonna use that you need Threebond 1104 or equivalent or for very hot areas RTV silicone

Not a good idea mate ,,, especially around petroleum it tends to break it down over time and will wash any over hang in your motor ,

Hi,
Hylomar is resistant to petrol.
After I built my 4L0 engine,I pressure and vacuum tested everything.
One of the MANY leaks I had, were the reed block gaskets.
I know there are "fors" and "againsts" for pressure testing, some say that they have built many engines,and never pressure tested any, and never had any problems, or that it takes as long to build the engine again as it takes to pressure test it properly, so its a waste of time.

After "pondering" the subject for a while, I decided that I was going to pressure/vacuum test mine, for the sole reason of peace of mind. I had visions of it not starting or not running right, and then Id be thinking, is it electrics?, is it fuel? HAS IT GOT AN AIR LEAK??? ARE THE CRANK CASE SEALS LEAKING??? ARE THE CRANKCASE HALFS LEAKING??? ARE THE BASE GASKETS LEAKING? IS THE HEAD GASKET LEAKING???....Then I,d be saying to myself.... "Hucking Fell", wished I,d pressure tested it, as Im now either going to have to rebuild it, or pressure test it to find what is leaking.
I suppose squirting Napalm or Hydrogen Peroxide or whatever it is your supposed to squirt on the gaskets and seals, may point you in the right direction, but although you might be lucky and get it, I dont see it as definative.......mabey I just like fannyin about too much, but I was in no rush, and it cost me a fortune, and I wanted to do it right.

I used an Athena gasket set from PJME, who did my rebore and crank.I used a calibrated Britool tourque wrench.
I took all the leaking gaskets BACK off, , got another Athena gasket set and re fitted them with Hylomar.
During this I discovered, after using Hylomar for years, that methelated spirits, takes Hylomar back off perfectly, which I didnt know.
After that, all the gaskets held, both with the pressure/vacuum tests, and while running.
I also used Hylomar to seal the crankcase halfs.
The only other "gasket goo" I used was silicone or RTV (room temperature vulcanisation, didnt know that to recently either) on the exhaust gaskets.
steven.
ps, the reason I like Hylomar is.....everywhere I have worked for the past 30 yrs or so has used Hylomar, so I always find it very reasonably priced.....
