OK Sam, I've weighed all the pro's and con's and have come to the decision that my 550 motor is coming out for a freshen up, and I reckon while it's out it may as well get a bit of tweaking & fettling

As you've been in this particular game for far longer than me, (I only bought my CB 6 months ago), and as a result probably know better than I do what to do, and more importantly who to get it done by.

So who in our area would you recommend I get the work done by?

Sam Green Racing · « **Reply #1 on:** February 13, 2007, 06:23:58 PM »

Well Mr Duck, now you're asking, I don't know anyone near to you Chris.
There is a place in Warrington that did our boreing and lightened and ballanced the crank.
They do head work but we got ours done in Lincolnshire and they have moved to Ireland.
For what he charges, you could send it to Mike in the States, that way you know you will get a top notch job.
Plenty guys on here from all over the world will vouch for Mikes work. We would have used him ourselves if we could have forseen the problems we experienced over here.
Give me a shout when you return to the UK and we'll get together for a chat.

Sam.

To be honest Sam, after reading both his own posts, and the glowing references from everybody on here else who's dealt with him, Mr Rieck was my immediate first thought, but I assumed the distances involved would be too great a problem/cost

Maybe I need to speak to Mike directly, and look more closely at the logistics side of things

I have no doubt that I would get a top notch ready to roll engine back

Most probably well before there was a re-assembled bike ready to receive it, knowing my own work rate as I do

BTW. I'm home for ten days at the end of May, no doubt you'll be taking me up on that offer I made a while back of a drink or two

God knows I'll ned it, you can't get decent beer over here for love nor money

I was refering to just sending the head for reworking.
Mike has sent heads to Europe so should be able to give you a price.
Send him a PM and ask.

Sam.

So who can I get to do the rest then

I'm OK with dismantling and rebuilding chemical plants, and agricultural stuff like my old Ford, but I'm all thumbs when it comes to anything this dinky

Thinking about it, I might try Mick Puffets approach and acquire a second motor to practice on. Though I might not go to the extent of seizing it before I take it apart

Sam Green Racing · « **Reply #5 on:** February 13, 2007, 09:03:25 PM »

well why not, keep it on the road through summer while working on a spare motor.

Sam.

hey we all make mistakes

, have a go yourself with the engine there not that complicated

, mick.

Jesus Mick! What are you playing at

You can't go admitting things like that

There's wimmin on this forum, we'll never hear the end of it now

bryanj · « **Reply #8 on:** February 14, 2007, 05:58:16 AM »

Instead of sending your head, buy one on ebay in the states and get them to send it direct to Mike, preferably with the inlet stubs.

The 550 is an easy engine to work on and most work needs no special tools at all just care and good cleaning

CrisPDuk · « **Reply #9 on:** February 14, 2007, 06:57:42 AM »

That's a thought worth entertaining Bryan.

But how would I know I was getting a/ the right head for my bike and, b/ a decent straight one?

MRieck · « **Reply #10 on:** February 14, 2007, 07:39:14 AM »

I'd be more than happy to help you out Chris. Shipping a head air mail to europe is about 90.00 to 100.00. Bryan's idea is a sound one as I'm sure you could find a 500/550 head for less money. To bad it wasn't a 750 as I have a few spares.
Mike

CrisPDuk · « **Reply #11 on:** February 14, 2007, 07:31:17 PM »

I was going to drop you a PM later today Mike.

Is that $90 to $100 US? It used to cost us over twice that to airmail things of a similar size/weight from europe to the US

I don't suppose you're any where near Boston are you? Somebody on another thread has got a whole 550F motor going free to anyone who'll collect

As Sam will confirm, me and my CB are not exactly in close proximity at the moment, so when I get back to the UK I'll get in touch and we can work something out.

What would you recommend with regard to the bottom end, as far as a rebore/overbore/other goes?

Sam Green Racing · « **Reply #12 on:** February 14, 2007, 08:15:46 PM »

Back in 10 mins Chris.

I'll check my ol' bin of parts - I might have a 550 head that you can have. I'm in Toronto, so would need to ship to the US for the work.

I rebuilt my engine myself (550F) this past fall for the first time. Was no problem. I had my head worked on (just a valve job) and cylinders bored by a machine shop, but did all the wrenching myself. Took me a couple of hours to break the engine down and get the pistons off the rods. Putting it back together took probably 4-8 hours total, including remounting carbs, hooking cables back up and what-not.

If you're just doing the top-end, go for it!

Maybe my thread on my reassembly will inspire you

Had to do a little work

PM Mike, Boston's 25 miles from Mikes home, he will help you if he can.

Plenty of people on here have hopped up smaller fours and will point you in the right direction.

Sam.

CrisPDuk · « **Reply #17 on:** February 14, 2007, 09:22:11 PM »

W**k

It's a bugger when that happens

I'm going to drop him a line this afternoon when the boss has left

Thanks for the offer Tintin, I may take you up on that. I must get over and introduce myself on yor forum too, I've already done he registering bit

Sam Green Racing · « **Reply #18 on:** February 14, 2007, 10:01:39 PM »

Chris, if you keep it simple and just do the work in the head, you won't have to worry about reliability.

You can get your cam re ground at Megacycle for not a lot, I think they do one that gives good mid range and top end.

I think it is their 126-01 cam, you can run stock pistons and valves.

Sam.
