Competitive F3 bike set-up costs?

[Ivan]

Yep - my PT owes me 10K. It has nearly as much as you can do to it (bar cam timing adjustment and full race exhaust). Also including spare wheels and tyres.

At VMCC Club level, Pro Twins are always up the front of the field with the F3 bikes. (unless GW is there)

ip and also put to there are a few pro twins for sale allready speced ready to go and could be used as a f3 bike and still be competive I mean look at Geoff at Nats

[lostinflyz]

yep a pro twin is pretty close to there but even booth and co are usually at least 1-2 sec off the pace of the front of nats f3. and in finding those few seconds are what cost serious money.

Yeah but there is a competitve bike from the start and you could then build it up from there gixxer front heads cams etc but you have a good base line bike

Sorry, just deviating a little from the topic here.

Someone mentioned turning a 600 into a F3 bike...

Whats the story there? Old 400 engine in a modern frame? 600cc engine sleeved down to 450?

there is 2 ways i have seen this done. taking a 600 and dropping a cylinder. the other is a 600 with a shorter stroke. both intresting ideas. and what ive seen very fast

I believe they take a 600 and "block off" one of the cylinders. Not sure of all the details but I think usually the piston is left in but the cylinder is not fuelled or firing. I am sure someone who has a clue about these things can probaly explain it better. It gives you a modern bike with readilly available spares and hot parts that meets F3 requirements.

everyone so far i know has turned a modern 600 into a 450 by dropping a cylinder, but has anyone done it by short stroking a motor???

I looked at doing it but it was going to be quite expensive and i have no idea how well it'd go.

I don't know how you'd go about about sleeving one down as as the valves would strongly disagree with it.

Ivan your right, the SV has so far shown to be pretty much the best baseline f3 bike, for both club and nats.

Yep. the latest bike rider magazine has one in it. Glen williams done the test. great read

I don't have a missus to remind me im an idiot though so it makes it easy..

Not all missus think that racing is a dumb idea. Some are rather encouraging of it all, and find it interesting. If you find a women who is prepared to travel to race events, and spend time standing in the cold and wet watching you race, and finding out about the sport and your bike, you have a keeper. And I don't think people come across many women like that in their lives. Lol.

My advice would be to get a Protwin bike and race that for a while. You race against F3 and if you then feel you want to outlay alot more cash to be competitive in F3 at National level then upgrade to F3 spec depending on what that current rules are when you do.

Having said that its probably easier to be competitive in F3 than Protwin at club level. At least at the Vic Club anyway as Protwn bikes feature more at the pointy end until the end of the season when the nationals guys come out to get set up for the Nats.!

All the best F3 riders come from Central North Island LOL

Glen williams has the aritcle on the short stroked 450 on his website. very interesting. Its cool that someone actually did it and i have to say good job. Hopefully they can sort more power.

When i looked into it i came up with a red line somewhere around the 18-19k redline mark for max mean piston speed, which would be interesting to try acheive.

Yeah it's Greg Percival whose bike it is. That test in the article was at the end of last year. Greg has done more development now and is steadily improving it and still has a lot more to do....... will be interesting to see where he gets with it. At the last round of AMCC he was on par with a ZXR450 and FZR450 at the front. Lap times at Puke about 1m06 - Sketcky in the TT on Ozzy's one 1m03???

My lovely wife wouldnt be seen dead standing in the cold watching.
She is more into standing around in leathers and lining up on the grid.
With two of us having the bug there is no arguments about the money involved (Pay mortgage, buy food, all remainder is for racing!)
Now thats a keeper!

My wife encouraged me to get into it. She didn't like the way my mates and I were riding on the road. She absolutely loves coming to the track to watch and enjoys the whole atmosphere.

If you want to get a cheapish competitive F3 bike I think a 450 is the way to go at the moment. They are fast enough in a straight line and have supersport handling.

If you want to race in pro-twins and still do well at club level F3 then get a 650, but to make a 650 competitve in F3 at National level will take big $$$ and effort.
