Older RGVs vs Later RGVs?

[Coyote]

How much would it cost to freight a bike from the UK? You can get some very cheap RS250s from there

Also, what about this: http://www.trademe.co.nz/structure/a...014&permanent=
Bid on that today or hold out for that RGV racer (closing Wednesday) or look out for a NSR?

Can you race TZRs in F3? How do they compare to the RGV and NSR?

[nsrpaul]

reverse cyl tzr , possibly the most unreliable of them all , when they were imported into nz yamaha nz did 100 odd mods to try and hold them together , didn't work tho
look cool and cheap tho , and fast for the five mins they run in one go
3vx tzrs good , but hard to derestrict

OK,
here we go again......
Early RGVs ie the 89 and prev 2 stage chocolate power valves.Bad power valve pin design,pin came loose after not very much use and the power valve slid into contact with the piston.
Later RGVs 1990 on 3 stage power valve.1990 to 92 chocolate power valve with pin that comes lose.Suzuki up graded the pin made it stronger but the design means that the power valves fail.They still fail just takes a bit longer.
The last of the RGVs had a different design but you dont see many in NZ.
Aprilia RS250 a worked RGV hmmm.Have to say no.The motor is still the RGV motor and all the dynos i have seen show it to be no different.As for the rest of the RS,much better than a standard RGV.
The NSR has a very different power valve to the RGV much more reliable.
But all these 250s are good its just a case of what you get and how you treat it.They need more care and cash than a 4 stroke but its worth it!.

Since I want to race in F3, would a 2 stroke be the best way to go or a 4 stroke? I imagined that if I blew up a 4 stroke it was gonna cost a hideous amount of money unlike a 2 stroke. Then again what are the chances of me blowing up a 4 stroke anyway? Should I just get thisas it's cheap?

Wasn't TS going to sell his ZXR?

Just to point out a correction, Fluffy...
Attached photo is from an 'L' model, note the complete lack of pin to come loose.
These are the two stage version, with power delivery not as smooth IMHO.
I can't be arsed stripping my engine to show you the later ones, but you get the idea.
I don't think anyone could argue that PV's are the achilles heel of the RGV's, I hope they shot they guy who did that one, but they are not as bad as people make out.
As Fluffy (and others) have said, maintence is everything.
The earlier bike (K and L) were slightly lighter, and argueably better forks, usually having more adjustment.
I liked the looks of the later ones, but I doubt there is much difference if tuned properly.
I say go 2 strokes, easy to fix, (you have to do this yourself to make sure it's done properly) and heaps of fun.
4 strokes (zxr400 etc) all good, faster out of the box, but you depend on getting a donor engine if you blow yours up.
If you want to win F3, get a SV700 like Frosty...
I liked the RGV over the NSR because: 1, Looks better and 2, slightly larger.
The stock power valves can be fixed, or you can buy new ones from www.rgv250.co.uk

GO RGV 250!!!!!!

[Coyote]

Ah screw it. Got an RG150

[Fluffy Cat]

Oh man got a bit sideways there CG was thinking of the early 3 stage valves.Well spotted.
Now my NSR is going to spank your RGV so poo baa!.

[curious george]

WTF!?!! Dude, that's 100cc's short! How far you gonna go in F3 with that?

RGV's rock, nuff said, havent had any probs with mine since i bought it over a year ago, its '89 and runs like a rocket, but i want to derestrict it sometime soon i saw the auction for the race one on trademe, but have no funds

[Squiggles]

Actually i heard he got promoted - I also heard that this problem was for bikes that had been ridden slow.

i heard that too, something along the lines of that riding it "slow" would lead to a build up of grime around the powervalve pin heads, which would wear them away, they snap, thingy goes thru cylinder casing, and u're fooked...... correct?

[curious george]

i want to derestrict it sometime soon (

How are you planning to do that?
What's your starting point?

[Coyote]

WTF!?!! Dude, that's 100cc's short! How far you gonna go in F3 with that?

I thought I should stick to Streetstock. All the bikes are the same so if I do well in it it'll be because of how well I ride, not having the faster bike.

Also I'll see if I can do a motorcycle courier job over these holidays to get the funds for an F3 bike.

FYI, there's a gorgeous Lucky Strike coloured 93 RGV for sale here in Chch at the moment. The bike shop on Moorehouse ave has it I believe (saw it on BikePoint)
