400/4 build. Paused due to other commitments. But starting up again

[K2-K6]

Other questions that ive got....

I want to fit a MotoGadget MUnit...anyone else fitted one to these?...(ive already got the electronic ignition conversion) along with LED replacements where possible.....the idea is to modernize it but without affecting the look of it.

Can't immediately find it, but a previous project on here used motogadget setup and will show that experience on a 550 I seem to recall.

Cool - ive got a few pdf/wiring diagrams but thats way in the distance!!!

I doid the 400 0n a mptogadget aset up and going to do the same with the 550, its a great thing.
The thread you refer to is eight0 and his thread calld, "What have i let myself in for"

I have a brand new MUnit blu in the box for sale if you havent already got one as its surplus to requirements. there's s few things Ill do differntly tis time but on the whople it was a fairly easy installation but really satisfying.
Double Fonzy thumbs up from me.

Hi - yes i will definately need one!! an Munit is an absolute definite.

[Laverdaroo]

well there's one here if you want it. I got a deal on three so I can shuffle it on fairly cheaply.ones on the 400, one's going on the 550 so theres a spare.

Having seen the state of the engine now I understand why you stripped it! 😳

If these links work, there are a couple of 550 looms  with m- units which might be of interest.

[Laverdaroo]

Go to REVIVAL CYCLES and have a look at the youtube site for fitting videos, dead easy and really straight forward.

I'm going to put this M unit Blu I Have on Flea Bay as I need to get some forks bought to replace mine and its both legs so if you're interested I need £265 inc postage. If I dont hear anything I'll get it on there. Anybody else interested,l et me know.

Cheers

Back again. So, first and foremost so many thanks to Bryan who has rebuilt the engine, which is now back in the bike....im on the garage laptop at the moment so ill upload pics from the phone in a bit. Essentially its probably about 3 years since i pulled it apart so no real idea of how it all goes back together....if anyone can advise from the pics which is the next best part to refit any and all suggestions ill be more than open to.....Bryan still as the carbs but hopefully they should be done in the next month or so...!

As i say and stress if any of the veterans on here can give me some pointers on the next best parts to fit im all ears! and eyes.

And once again Bryan - take a bow - if i didnt find you i dont think it would have ever gotten built again!!!

Cheers

Andy

You might as well get on and get all the brakes and levers on it, lights (shell) get everything on it that needs to then its all ready for teh wiring attack. Thats what i'd do.(did)

[ComfySofa]

Ok....not sure what goes on with the airbox....looks - quite involved.!

Oh - do you still have the MUnit?

[Laverdaroo]

I'd wait to get your carbs on before playing with the airbox but happy to be told otherwise. Youve heaps to get on it before the airbox but those that know a bit more may say different.

Sorry, I sold it just last week, a good job as I found the receipt and saw that what i was asking was quite a bit less than I paid for it. I just broke even in the end. Louis Moto have them in stock as do a few others, you should be able to find one pretty easily but shop around as they vary in price quite a bit. If you can get it down to near 300 quid you're doing well. Apologies for that, had to shift it on to pay for more spares........you know how that goes!

[ComfySofa]

Absolutely fine sir, no matter!....airbox coming off tomorrow...! this is what i need....to save re-assembling multiple times for no reason!!

[Laverdaroo]

Julie's the girl to speak to but look at it logically and think what needs to go where or what can i put on thats not going to hinder doing major bits going on later. You'll end up doing things twice, thats half the fun.  It all has to go on before the wiring but take youre time, clean where required and enjoy it, it's supposed to be a hobby


If you are going down the M unit route, order the delux wiring kit from Revival cycles in the states. Their pack is far superior than others sold on ebay, internet etc. Every wire has it stamped on it at various intervals what its for which will help you immensely when doing the install from scratch, especially if youve not done it before. The only thing not on the wiring diagram I got from them was no provision for oil pressure switch and no neutral but once i'd got that far I'd sussed it nd some help of one of the users was invaluable. Just going back to revival cycles, their fitting videos are brilliant, as is their kit. Also watch Classic Octane on You tube, he does a great video on how to hook the m unit up onto a 550 including keeping the switches as is and using them into the mix. Really useful.
The wiring kit is a must though it's absolutely spot on.
