Compression tester anyone?

[Hightower]

I'm after borrowing compression tester for 15 mins this weekend. If anyone can oblige, I can offer a cupper and a peice of cake, or something stronger if preffered.

If pete's won't fit the plug holes, I've a couple of adaptors for mine where I've worked on various odd bikes and cars I've owned.

Thanks guys, will phone you tomorrow pete.....Sorry if it's too early, but have busy day ahead at the "outlaws" and want to get the test done.

Thanks Nasher, will keep you in mind just in case. Stopped your globe trotting yet? I'm looking forward to the next RIBnet gathering, so i'll see you there.

122-125-128 PSI cylinder pressure on a cold engine, is that good?

[Mark Halliday]

Seems OK Andy

If one is significantly different, there is a problem.
Actual pressure is meaningless (ish), unless they are very low. As yours are almost around half way round the gauge, I dont think you have a problem.
Is this part of looking for the phantom knocking?

[Hightower]

Yes it is Mark, but I'm not totally convinced I really have a problem, on my last outing with Zippy a couple of weeks back, everything seemed OK apart from a temporary loss of drive going though the small boat channel at Pompy, but that was probably a peice of weed or plasic bag that came off when I lifted to inspect.

It could be back firing I can hear from the exhaust, I'll run her back up next weekend and have another listen.

Another Question: I ran my Yam "dry" to empty the carbs of fuel. Is this going to cause problems on restarting with regaurds the oil injection system or shouldn't I worry?

Andy are you premixing the fuel?

[Hightower]

No and I don't want to, as I have an inboard tank and can't give to fuel a good mix up before a voyage.

[Nick Hearne]

Then if you run it dry you will still be pumping in oil which I undersand is not a good idea!
