Mito 443 Project
Discussion
paint wise Yamaha blue like my old R1 but not sure on decals and all that. I'm not doing a full blown paint scheme though.Having rode it the other weekend highlighted a few things needing some attention. As I've already mentioned I modified the fairing so I could move the clip ons back up, they fouled on full lock before - having rode it now it's infinitely more comfortable than it was last week. Also done some fibre glassing on the seat so it fits round the tank now.
Changed the chain adjuster bolts, the ones I had in were m8 but had a 10mm head, the mito adjuster blocks have a little recess and it pulled the head of the bolt into it so every time I adjusted it the f
king thing just went loose again so just put some normal m8 13mm head bolts in.
Another thing I noticed was it had leaked a bit of coolant, turned out when I fitted the clutch cover the o ring that goes on the tube that goes into the back of the water pump got damaged, so off that came, about 15 quid worth of gear oil dumped but at least it gave me a chance to check whether there was any crap in there, looked clean enough. New o ring, gear oil and full coolant change done.
The steering head bearings weren't torqued properly, re did that and now I can happily sit back and roll along none handed and it tracks dead straight.
Fuelling wise it's still rich and has to clear its throat a little bit much more rideable now, I don't want to lean it off any more until it's been on the dyno.
I rode to my mates and had no wrist or back ache at all, spot on. Did notice it felt a little vague front end, added a bit more rebound and it feels great now. It's so light it's telepathic. I'm really quite pleased with how it feels now, it's more confidence inspiring to ride than my Zx6 track bike.
Also considering it's still not set up properly it's now quite happy to roll on and whilst it's very brutal and rather sudden when it does come on the power, the mid range really ain't that bad and will only get better once the ignition is mapped and carbs are fully jetted.
Very happy, it feels like a different bike to last week.

Been doing minor bits and bobs, tidying things etc. Had to do some more fairing mods as they were still fouling the kickstarter and on inspection the clutch cover was digging in the belly pan so made a little window..
Unfortunately the cans came a little loose so put some extra rivets in the end, can't tell but gotta be twice as sturdy. Also made a bracket to give the stingers some support as the last thing I want is the welds cracking from the spannies to the cans. It's a bloody long bracket but the seat will cover a fair bit of it when it's back on. It's now ready for the dyno next sat.
Also been playing with the carbs as I have a large flat spot with it being to weak mid range - I tried the needle that Martin @ mad biker uses in his older style TMX carbs and it ran fking awful. I put that down to them not being compatible with my later style TMX carbs, I couldn't find a definitive answer whether they were interchangeable, even allens performance didn't really know. Then from chatting to allens performance I realised I was probably using a totally different needle jet, had a chat with Martin and it turned out that mine was waaaay bigger than his so it wasn't compatible with the needle. Changed those and it runs well, quite confident I have a base to work with on the dyno now. Bit of a mixed bag my dealings with allens - one of the blokes I spoke to basically said to me that if I didn't know exactly what jets I needed I may as well give up and get rid of the bike or buy loads of random needles to try even though I'd already said I'd tried a thinner one. Next time I got the older bloke and he said straight away you either need to stick with the needle you have and get a bigger needle jet or go with the needle you've been told works well and get the matching needle jet - very helpful and job done, on my door mat the next day.
As can be expected there have been some teething probs - the SV650 Gen 1 radiator doesn't really seem big enough, it's being blocked a fair bit by the big upside down forks and it looks like the front tyre has touched it, when I fitted the rad fan it had to be pushed out a little which has put it more in line with the front tyre, no good. Fortunately the Gen 2 SV650 rad will go straight on, is a bit shorter for more clearance and a fair bit wider, luckily I have width to play with. With a slightly smaller fan and that radiator I reckon I'm sorted. Shame but st happens. Apart from that everything seems good, it rides nice but with the big flat spot I've had and bearing in mind I've been shaking it down I've not gone mad, but happy with where I'm at. Fairings are now off for paint and the bike is all ready for the carbs to be sorted and ignition mapped up.

Looking good bud 
Out of interest, what ignition map are you running at the moment?? Be careful not to chase the jetting unless you're 100% that the ignition map is good. Could be very easy to cause flatspots due to ignition and not fuelling....
Hi mate, it's the one Martin uses on his 421, I've had a look at it and it's not massively different to a standard curve. I'm also set at standard base advance to be safe. It's not going anywhere under its own steam now until it's been dyno'd as you are of course right there's too many variables. I have no clue how they used to do it in the old days without a dyno!!! A sensitive bum and lots of plug chops most likely!Out of interest, what ignition map are you running at the moment??

I'll have a look Steve.
Can't say I'm pleased with the exhaust hanger I keep looking at it, have to see what it looks like with the seat back on. Not much other options for mounting points and id be happier with it fitted. Needs some shape or something.
Personally, I reckon having the cans unsupported is going to have them work loose at the bottom end of the can with the rivets working loose.Can't say I'm pleased with the exhaust hanger I keep looking at it, have to see what it looks like with the seat back on.

Maybe look at a couple of P clips that meet in the centre and fix to the frame from there....

I thought about that but there's barely any gap between the cans for them to meet and provide a mounting point.
Then stagger the P clips and place a strap between them. Then fix the strut to this link strap..otherwise those cans will start to come loose at the root.
What about a strap that ties the can to the stinger somehow??
