Re: new remanufactured check valves
Am hoping that someone offers a service where they replace the check valves in a customer's lines.

Fair enough Pete, didn't think of that.Pete O'Dell wrote:because people like me who deal with suzuki engines day in day out have a larger customer base, not all customers want too do the work, and specialsist probably have far more contacts
Think of how stupid the average person is, then realise that half of them are more stupid than that.

Re: new remanufactured check valves
Thank you Dave.givemeagirl wrote:In reply to Ian question, the new remanufactured check valves have been produced by a British based company who are specialists in this field and manufacture check valves large and small to many industries which includes the British and European motor industry they also manufacture high quality components for the electronic industry.
Like you, a few of us have reproduced parts for these bikes (Shaun's points covers, my GT750J clock shells, Pete's T500 con rods and bearings, etc) and it often is a thankless experience as the upfront costs are high for small/limited production runs making the unit costs seem high. You are to be commended. I was curious what you suggest for the in-line check valve on the GT750 - just replace the end with s standard valve and leave as is ? Or does yours come apart allowing the internals of the in line one to be replaced ?
As Pete has mentioned, there are a number of engine rebuilders who might be useful contacts for you. Pete is one, but as well in the UK there is Barry Wilkes and I'm sure the Kettle Club could also supply a few names. I can send you some email addresses if you are interested.

Re: new remanufactured check valves
as a matter of possible interest to some in the UK, thought I would just say although I specialise in Suzuki 500 twins, I also do any other suzuki's aswell currently doing a GS750, 1 x gt185, 2 x kettle engines, 1 x 380, 2 GT250 and a 550 due in.
CBX1000 on the go, Norton Navigator having total rebuild, RD400 being monoshocked and upside down forks general customisation.
so am a busy little bee lol with 6 500's in and 5 engines, anyone know where I can get 28hr days and 8 day weeks lol

Re: new remanufactured check valves
And even small time operators like me need them. I have 4 GT750 project bikes in the shop from a resto-mod through to custom framed reed motor projects and at least 3 of those need at least 1 replacement check valve.

Seller 'cloudcuckooland2000' I think!!
Tell you what Pete, I'm going down to 4 days in the new year (winding down) so you can have my 'old' Fridays free of charge.
Just so long as I don't have to do anything with them other than my 550s, clay shooting, model helicopters, scuba diving, caravan holidays or one of the other hobbies I don't currently have time for.

Re: new remanufactured check valves
I like the idea but at 11 quid each x 6 plus shipping and labor and shipping the repaired lines back, that comes out to about $175 exchange on a good core.jabcb wrote:Am hoping that someone offers a service where they replace the check valves in a customer's lines.

Re: new remanufactured check valves
I think the check valves are more of an issue on the T-series twins. They have a different pump design & have 2 oil lines that split into 4 lines.tz375 wrote:I like the idea but at 11 quid each x 6 plus shipping and labor and shipping the repaired lines back, that comes out to about $175 exchange on a good core.jabcb wrote:Am hoping that someone offers a service where they replace the check valves in a customer's lines.
I had a T350 where the right-most line would slowly fill with air if you left it on the side stand for a few weeks.
But if you then put in on the center stand it would slowly fill with oil again over a few weeks.
Solved this by installing NOS oil lines for the right cylinder.
At the pricing you mentioned, oil lines for a T-series twin might be $140 with exchange of a good core.
That's cheaper than NOS lines that I've seen recently.

One of the problems with sending to USA or Australia is the cost of the postage £8.90 first class signed for, maybe after xmas if someone in the USA or Australia wants to offer a exchange service IE to fit the valves to customers oil lines they could buy for example 100 valves at a reduced rate and the postage for 100 in a large pack i'm sure would be much cheaper than lots of small packs, also someone changing lots of valves will soon get used to the job which would be much better? i had thought of offering this service myself for UK customer ?
let me know what you think guys ?

Re: new remanufactured check valves

That's 22p each.
Do they think we're made of money?
How much spit do they think it takes to stick a stamp on a package FFS?
Hells teeth. Me pensions not going to last 5 minutes!
I'll have to drop down to twins or even single cylinder bikes as I get older!!!!!!!
Gub'mint barstewards!!!!

Re: new remanufactured check valves
Well, Alan, we know how pensioners start to get unsteady as time passes. Maybe you should skip the twins and one lung bikes, and you can move right on to this beauty.
