F3 TZR

[saltysealion]

Any updates on a F3 seat?

My build is coming along and I'd really like this seat!

What model 3xv 3ma or 1kt ?

Tzr250 F111 original with full kit.

I am back to setting up the 2XT F3 race bike.
The 40mm YPVS radiator from China is now selling in Aus for $AU89 delivered. Bargain!
Mine is back from having a filler spout added and the T removed.

Hi, my F3 is not far off the TZ 350s ,i guess 65 hp in there some where.
This is with all  the mods that Mark has minus the lectrons .

Just a small update.
I switched over to one of the Chinese TZR250 radiators but it did not provide enough cooling.
So I went back to the modified 40mm YPVS radiator.

Was that at Wakefield Park recently Mark?

[mboddy]

No. I ran the TDR with 2XT engine at Wakefield last weekend. 2nd in P6 500cc 1 Hour (five P6 500cc teams).

Planning on taking the TZR and TZ350F to 2019 IFoS.


Update: I was happy to take the class win at the Festival of Speed in the P6 250 GP class on the TZR and TDR.

2 years later,,, is anyone building a F3 machine?

[mboddy]

I continue to develop mine. Was hoping to give it a good race at the 2020 Festival of Speed but it was cancelled due to the virus.
Thanks to Penrite and MotoGarage for their continuing support.

Also thanks to Dan at Gecko Racing for his assistance  http://www.geckomotorcycles.co.uk




The ARD racing fairing has now been replaced by a F3 fairing from Seppo at Shop97 in Finland.




The F3 fairing let me get lower onto the tank but I needed to get the foot pegs even further back
The SES rearsets that I got for this purpose got my feet where they needed to be
but my pipes are tucked up a bit higher than the rear sets were designed for
and so I made some modifications which also let me keep a horizontally mounted Brembo master cylinder. 
Also I used a SES TZ250 4DP brake lever.




I had to make my own gear lever to clear the pipe too.
Here is my template over the half completed gear lever over the SES gear lever.




And here it is fitted on the bike.




The Scitsu temp gauge packed it in just like on two of my other bikes and so I have gone back to VDO.
Finally fitted the F3 kit tacho.

The big improvement has been the Andreani fork cartridges from Omnia Racing. They set them up for my weight.
I fitted them along with NOS fork tubes and used Penrite 5wt fork oil at their suggested default level.
They replace the damper rods and springs and require the bushs being removed from the fork tube in a lathe.
Raced it at PCRA Rd1 at Wakefield Park earlier this year and took 2nd in class.
They were a big improvement just using the default settings and I didn't find anything wrong with them and
so I will leave them at those settings until I notice something that needs improving with them.
Most definitely worth every penny!

Same here, this year is reserved for old projects that are still pending ...

So far I have one engine built up. It is a 2XT motor, full FIII race kit, straight cut primary gears, gas flowed cases, ported cylinders and re-profiled heads. Hope to build up the rest of the bike over the coming months. Fingers crossed it should be a fast one.

Hi Mark,
Can you post more detail on fork cartridges  from Omnia Racing ?

Olivier.

[mboddy]

Adjustable from fork caps for spring preload and compression damping left cap and rebound damping right cap.

Thanks Mark.

quite a good amount of cash but front end is now up to date and legal to your racing rules in class 

[saltysealion]

Wow, thanks for posting some updates guys.

I am back working on my TZR and this is really motivating
