RZ350 CDI I could borrow?

[Sean'o]

Any of you fine gents got 350 CDI i could borrow. As ive dynoed the thing with a 29L-50(250) cdi on it, I would like to throw it back on the dyno with no changes other than a 350 one, just to see what difference it makes. 350 ones are 29K-50, 1UA-50 or 52Y-50

[g0zer]

you can borrow mine if you want sean

[Sean'o]

Cheers, will have to book the bike in and work out when your not using yours for a day or two. Any idea what model yours is?

[g0zer]

Nitro(methanol)

Nitromethanol, also known as RC-car fuel is an alcohol based fuel that burns faster and hotter than gasoline. This increases the performance greatly.
But as most people know, alcohol dissolves oil. And oil is what keeps your 2-stroke going. Also the added heat can cause your piston to over expand and instantly seize. So you will need a good lead-replacer (The type that goes into old cars that run on leaded fuel) to insure a good heat-conduction of the piston and cylinder wall. Also you will need special nitromethane 2-stroke oil, so the oil doesn't dissolve.
Don't use more than 15% nitromethane, as it will surely kill your engine. Mix the oil and lead-replacer with the fuel in the right proportions, shake and take for example 850ml's of that mixture and add 150ml's of nitromethane. Start the engine on normal fuel and run it till it is completely warmed up. Then switch to the nitromethane mixture.
Beware: You can't kill your engine by stopping the ignition anymore, the nitromethane mixture is self-combustible under pressure. So make sure you can cut the fuel off at any time!
side note: Ready to run "nitro" fuel (as intended for rc cars) is a mixture of mostly methanol (practically alcohol), oil (caster, synthetic or both), and typically has around 20% nitromethane added in though that can vary from 10-40% by brand or type. The percentage of oil might range anywhere from 8% to 25% with 15%-20% being the typical amount of oil found in nitro fuel. Up-jetting is a necessity to obtain a stoichiometric balance. A loose rule is an engine must burn twice as much alcohol as gasoline.

Some feedback if it helps.

I chased all over the net and the Forums
for info on which CDI is better ok..

52Y is the prefered unit..
29K give trouble
1UA have the retard issue...

I use a 1UA, and the thing goes like a projectile
leaving the muzzle of high powered rifle...
but i don't take it over 7 or 8..
and it's still pulling..
standard cigars.
tuned perfect carbs.
air box intact, mostly..

[Sean'o]

Thats what ive come up with as well robo, the 52y would seem to be the best one. The 1UA's had a higher HP engine but they knobled it a bit with the cdi.

I was going to try and book it in for next friday gozer. Do you have a spare cdi or just the one? will have to grab it off you and see if i need to make up a link cable or if it will just plug and play.

[Gangus]

If its not rz exclusive affair I would like to throw mine on aswell to mix it up a bit. Would be good to get a a/f reading.....

[Sean'o]

Its not an RZ affair, its not a special day for it, you can book it in any time you like. if you want to come when go there im sure we could organise something between us.

sounds perfect for seano's

[g0zer]

just the one in the bike just let me know when you want to borrow it..

having the rz off the road for a couple of days while you figure it out and get dynod is no stress

you can borrow my pipes too if you want i will pay for that run

[Skut]

The Bee is laid up at the Malaga office at the mo, not sure which CDI is fitted but will check monday. We could just pull it for you.Your run on the way thru if its different to what you have. You probably come right past there anyhow!

[smoker]

Hi, sorry haven't said anything sooner, that RZ flywheel on my motor didn't make the transition well, bastard thing knackered two pullers (must be original, damn it's tight), 'fraid the stainless cutting wheel and a gas axe were the only answer. May it RIP.

[Rob]

you need some cunning
