sounds like the name of a pub pig to me ..lol

Hey Scott while you have that GPhundred apart compare the gearbox shaft spacing to the supply of FXR boxs you likely have as well seem to be the similar shaft spacing

ok will do

Then whip me up a TZ350 tank would ya

does not look to hard . Show me the rest of the bike

You have a great sense of Humour
i actually have al the main parts now forks rims hubs frame RD350LC cylinders dash Discs calipers just need RD400 crank and a million odds and sods parts.
Tank and seat is the only other major part other than the 2g that the engine will cost to rebuild it properly. the seat is easy i dont have the skills for the tank i started to do the buck but then had the accident where i snapped my Humerus and fractured L1 and 2
Boiler got replaced this year and had to buy cattle and a heap of baleage plus ute 1/2 and new bike 1/2 finance for mr 16 so cattle money which is my bike money has come up short.
I actually did a list of parts, its pretty short.
its on half rego now. So its a toss up what to do first that or the BSA A10 in the Short chassis.
Boy is old enough to road race now as well so i guess the bucket might need doing as well.

Ignitech 50. Hey what you were saying in the pits yesterday, Chris' mate had taken the flywheel off the 50 and was having some trouble working out how to time it, so be aware that it likely isn't right.

we have changed it to non charging now but yer you are prombly right as could not pull the skin of a rice pudding when we got it

why not leave as a 350 ?

I could,but it costs the same to rebuild a 400 crank as it does to rebuild a 250/350 crank.
The 400 crank can be made to fit the 350 cases with a bit of a trench and a spacer.
A guy here has one i just need to convince them to part with it.
I already have the 400 spec gear box with the better ratios.

[TZ350]

.
For a 350 there is quite an advantage to fit a 350 crank into the more cavernous 400 case and use the longer 400 rods when rebuilding the crank to get as much crankcase volume as possible.

Really? That CR250 stator was a real push and go with enough power to run a pump if required. I'd buy it back if I was reentering the market.

I was thinking of using KTM200 rods i know the 400 cases are better, but 400 cases are pretty rare beasts theses days.


C-C little end width C pin C pin length
KTM200 118.00 16/20 16.00 22 55.00
RD250 110.00 16/20 16.00 22 51.00
RD400 115.00 16/20 16.00 22 51.00

but besides being taller are the cases that much bigger on the 400?
i know it can be done with 350 cases as that is what mark atkinson did on the road bike he has.
Arround 6 minutes in




Its not going to be the ultimate RD400, just the best that is available freely for beer money
Or i Scotts case hopefully high grade Moonshine....
Using the RD350LC cylinders and RD cases instead of RZ gear limits it somewhat, but they look cool.
I always loved the look of TZ A and B's more than the latter stuff. at least until the F an G's
so its a bit of a mix resto mod with the best parts of the looks i wanted.
twin shock early tank and seat but front a rear single discs with 320mm disc 4 pot and big forks.
As a kid i was to old for the RD air cooled phase but i always wanted a RD400.
If some 400 cases turn up i will buy some but i am not going to wreak a good 400 motor to build a bitza, that will likely never be finished off.
Its taken 2 year to find the mudguard i wanted, so it looked TZ with the cutouts but to fit a wide 17 inch rim but was top mount for the TZR forks the TZr forks took about 3 years to find.

All the TZ ones the right shape are side mounted i wanted it to look like a classic cut out TZ shape like a RD350LC guard only in 17 inch. This was a defining feature dating back pre TZ lat lasted for about 20 years.
it was the coolest bit on a LC, the rest looked kind of strange which is what happens when they put a pom in charge.

i actually enjoy finding the stuff.

[TZ350]

Yes the 400 crank wheels are a significantly larger diameter than 350 so the 400 cases have more volume with the 350 crank fitted.

Are you building for a dyno war or to have some fun and get it looking cool . That's how I look at it

[husaberg]

Its all about it looking cool, in a TZ racer kind of way. with is also functional, rather than a hardley like chopper.

if i wanted to win a dyno war i wouldn't choose a RD

The 400's are far more torquey and better on the road then the AC-350's, its not so much in HP but heaps in ride-ability.
i will confess I have actually never ridden a LC350, but the LC250's came in with a bang compared to a AC250 when i was a spotty 16 year old so would expect the same from the 350.
Adding in 8mm of stroke should mellow it out like it did with the RD400 for not much cash.
not only that if gives me the option to use the DT/IT/Blaster pistons which have a lower gudgeon and more overbores as the cylinders are already +1mm
Also if i steal the only non rusted crank i have out of the complete bike i will have a cafe racer and a complete RD350 with a missing crank
But mainly like i said, to rebuild either is the same cost. i haven't asked Grump what the CHCH dude charges to do a twin crank but i would wager i are not going to get change out a grand
All of them will need to have the crank done be it 250 350 0r 400.
i certainly dont have the gear to do a twin crank.
