TZ uniits are indeed 'plug and play' with 3XV looms, but I've no idea how you would get it programmed to work well with a 3XV motor? As they come, TZ ignitions produce horrible power curves with stock 3XV porting - they are closer with SP porting (though not as good as the right year sugo box in my limited experimentation). They probably have the best chance of working well with 93/94 3XV SPs as these run the same type of powervalve set up as the TZ - ie a single guilotine powervalve that operates on the main port only - but I've never tested this myself.
It may be possible to get it set-up for a 3XV, but unless you can priogramme it yourself, I'd think it would prove very expensive to buy and get set-up for your 3XV. Almost certainly a lot more expensive than a Sugo 3XV CDI in any case, which you simply plug in and go (though you should note that these simply do not work at all well with R porting in any case either).
As I say, it might be possible to set it up for a 3XV, but why bother when you could just plug in a sugo/YEC box thet is specifically designed for the job? that'd be my take on it in any case.
I guess you could mail the guy and ask about the prgramming bit though...?
Cheers.

|
|
Hi Arlurt .
Have you started rebuilding your crank up yet ? Have you ordered any
YAMAHA bearings & crank seals or other bottom end parts. If so , could you
let me know cost of above items for future reference. I have ordered all
parts needed for a top-end overhaul from WEBBS of LINCOLN , bill came to
nigh on £400.00 quid !! As & when they arrive, & also if it ever
stops raining , will be getting stuck in to the top-end & checking on condition
of bottom end. Hopefully , any wear is within limits of 3XV workshop manual.
Hope you find the time to get more done to your engine, it'll be worth all the
agro when it's all together & running.
Regards, Wullie Mc. _________________ Just when I'm about to make ends meet, somebody moves the ends ! |

Hi Wullie,
Only place I've found selling a kit of parts to rebuild your own crank is Southern Cross in Aus. If you search on eBay for 3XV and include international sellers you'll find their crank rebuild kits.
There are several places which can and do offer a rebuild service. I've spoken to a firm caled PJ Engineering. Stan Stephens will do them, and you'll find several people on here who have used other firms. Try asking Wb where he gets his rebuilt.
Chris in Ireland has just sent his crank off for rebuild (I think) so you could ask him how he's getting on. _________________ Light is right. |

Any Yam' dealer should be able to supply the parts, and any place that rebuilds cranks would be able to build and balance it - most of whom would source the parts too so you don't really need to get the parts seperately. As I mentioned in another post, the only part that a rebuild place that does TZ cranks probably wouldn't have in stock is the centre bearing and seal as these are a diff part No to the TZ part.
Cheers

Hi Warwick, fancy meeting you here, ha ha.
I just thought that if I've got the top end off,I should at least change the left
& right crank seals & maybe the two outer main bearings, just to make the
crank last long enough 'till I get money together for a SP crank. Been busy checking the workshop manual for crank assembly tolerances. All part of my
grand long term scheme. , which is 1, top end o/haul, 2, purchase
SP crank, 3, Stan Stephens stage 2 tune, & 4, decent expansion pipes.
Would then overhaul old crank & keep as spare. Until I get it apart, I've no
idea how good / bad a condition engine currently is, as it has been a transplant at some point in its life, barrels & heads are 3xv-00, -01.
Regards, Wullie3XV9. _________________ Just when I'm about to make ends meet, somebody moves the ends ! |

Sounds like a sound plan. I'd have a word with Martin77 about porting though (you might even talk him into doing a set of pipes if he's not busy with other thigs - pipes are very time consuming and labour intensive). Martin's Porting will be a much more thorough job than Stans (more expensive) stage 2 tune, where effectively he just raises the ex port a bit, not touching the transfers or even the auxiliary exhaust ports (an essential part of any 3XV tune) at all from what Mr. Stinkwheels (TZR forum) was telling me.
On teh dyno Martins tune was worth quite a bit more power over Stans, even though the Stan cyls were run with new pistons/rings etc, whereas Martins were run with worn ones. Mr Stinkwheels uses Lomas Pipes which look to work very well, though they are about twice the price of Martin's (assuming you can get teh lazy bugger to get the welder out, lol), which also work brilliantly. Your next best pipe option is probably the SP Tadao Jackals, but they are pretty hard to get hold of. The South African made Bosson Pipes work pretty well too.
Cheers

My final outstanding Yahoo auctions parcel came last week...
The new parts were a bit of a gamble, but seem to have paid off. I've got a new piston, two sets of rings, two gudgeon pins and clips. A full set of engine seals, and a variety of as yet unidentified parts. There are eight 4DP base gaskets and some other 4DP specifics.
The crank has (as expected) a dead big end, but this isn't an issue as it is the other side to the dead one I already have. I should be able to get one good crank out of the pair. _________________ Light is right. |

Having got two cranks with nasty dead big ends, and hoping to make a good one out of the pair I found a guy selling his old TZ bearings, seals and rods. I wouldn't dream of using the seals and bearings, but perhaps the rods might do as spares...

Why not, Karl? The rods, big end bearings, outer mains and the seals are exactly the same parts as you'll get from Mr. Yamaha if you order new 3XV ones (I always order such bits from Trollopes - TZ specialists - as they keep tjhem in stock so they arrive next day). If you don't want them I'll happily take them and put them to good use...
Cheers

Hi there!
My concern isn't that the bearings are from a TZ, the worry is that they've done enough racing miles for the previous owner to want to replace them. _________________ Light is right. |

Ah, right . I'd assumed they were new bits from his spares stock, not bits that had been pulled out of a motor when it was rebuilt. The bearings might be OK, but I'd be disinclined to use any of it myself if it's 'pre-loved' - other than the seals perhaps if they looked good and hadn't been in for long? But even then, it'd only be in extremis really as it's not worth taking the risk unless you are really pressed for time or £££s, but none of those bits are that expensive really and are all still available new. |

Hi there!
The thread's still alive. As for progress... My bathroom's coming on well, plumbing finished, drains in, on to the wiring now...
I've been working in India for a month, again, but that should be it for this year. Just out in time by the look of the news.
I was there for Diwali, which is what the fireworks stuff is all about. They're worse for them than we are on Bonfire Night, bangs and flashes at all hours of the day and night for a week!
Oh, you meant progress on the 3XV?
The only recent activity in the last month or so has been me half-heartedly bidding on eBay items, they seem to be going to a good home though, well done Chris.
My next step has got to be to sort the garage out. I'll have my bathroom finished around Christmas, then get rid of the building materials from the garage, tidy up, fit some shelves, build a bench, and have a right good sort out of all the 3XV bits I've foolishly bought.
Then I've got two blown engines to strip, the fun part at last. _________________ Light is right. |

Nice to hear from you Chris...
My eBay bid went in too late to affect the final price you paid, fortunately! I cocked up my last second bid and put it in after the auction had closed.
Pleased to hear you're making progress, you'll have to let me know how you get on with Stan. _________________ Light is right. |
