    You got that right Mark...
    Hey Moo I got the TZR carbs fitted up OK, the bowls are sitting perfectly level and it fires up and revs nicely on the bench but the proof will be when I run it which I haven't done yet, I'll take it for a spin up the street today but not sure if that will prove much, really needs to be on the track. The jetting will need to be sorted as the TZR carbs are 28mm compared to the stock 26mm RZ carbs..Any clues what size mains to start with anybody??

    I have read this thread with interest, from someone who rides a fzr4403jt and a rz350 this bike looks like a winner for the rz350 engine. I have wanted to put my prepped ypvs350 engine into a tzr 1tk to try and build a fast race bike to race in historics. . I am curious as to how the bike is now?

    Hi Graham Well a 95 TZR250 SPR Sugo came up for sale and I couldn't resist…so the RZF has got the cold shoulder for now.
    It runs and it’s rideable, handles very nice just not making good power, it’s the pipes I reckon, the chambers needed to be right where the 3TJ1 shock support part of the frame drops down, so we brought the pipes forward by doing cross overs with the header sections but it’s just not making the same HP as before, lost the straight length of pipe out of the manifold that they need. I will try jacking the engine up at the front which will pivot the chambers away from the frame and refit (slightly less) modified chambers….eventually…

    In hindsight a 1KT/2MA chassis might’ve been a better option but they already had a fast engine….If you’re serious, a good option would be to fit TZR wheels, swingarm, forks and a new race shock to your RZ chassis….that would make a nice Period 6 New Era 500 class weapon!!

    Cheers

    Thanks for the reply Glenn. Yer well a 95 tzr250spr sugo would give just about anything the cold shoulder. I see your in brisbane. Wouldn't mind having a look at your rzf one day. I'm not far of completing my rz350 engine, still hunting around to find an engineer shop that can o'ring the head and cut a new squish band. i know of a rgv banana swing arm and front end that could be the answer for the rz frame. Still like the idea of putting it into the early tzr frame. hmmm. Have you been racing the sugo in the motorcycle sportsman of qld championship? hope to go to the next round at morgan park. cheers graham

    Hi Graham One of the QEMSC guys that runs an LC could point you in the right direction as he has o-rings on the LC, I can give you details if you want to chat to him.
    I have run the TZR up there but I concentrate more on the 250 Production class on the CBR250RR for the Qld Championships, I will give the TZR a run in the support class at the ASBK round coming up on 26 & 27 August at Morgan Park.
    Next round at Morgan Park on 5 & 6 August will be on the Honda.
    Yeah you're welcome to come and have a look the RZF, always up for a chat all things RZ, PM me and we can organise something.

    Sorry we didn’t catch up at MP the other week, I crashed out in Qualy 2, cracked the engine case so took off to see if I could get it fixed but no luck so my weekend was over early.
    If you’re heading up to Lakeside for the Lord of the Lake Historic meeting this weekend, Rex (the treasurer of the Qld Early Motorcycle Sports Club running the event) will be there, he’s very approachable and will help you out with advice on the o-ring head.
