If a 90's GSXR 750 has sat around for 4 years what will it need?

[IronPawz]

I've a plan to buy a running early water cooled GSXR750 use it as a track bike over summer and strip it down over winter as parts for my old Katana. It is said to run but it is said to have not been used for 4 years. I'd say therefore it needs fork seals (which is fine as I'd do the suspension basics at least anyway). Tires (fine). Still I imagine if it had fuel that is now jelly and it will need the carbies stripped down which makes it impractical as a track bike (could just buy something cheaper and easier given only one season as a track run about, group 3/4 play thing).

Really I should just buy it as I want those parts. Can someone just remind me how much I will kick myself by not just buying it please?

Better than watching telly. Get thee a garage project.

I'm reliably informed that they're hand grenades. If it blows up, I'll buy the gearbox off ya.

I'd like the valve caps.

Yeah so I brought it and more besides. I'll wait for that wee announcement until it is squared away later in the week. So a track bike hand grenade sounds kind of appealing. At 71,000kms it must be getting ready to go bang. At least it will leave me with the front end and wheels I want for the Kat if it does! Godz know I've not been able to find them for love or money (even on ebay).

I'll see about getting it on the track for now so it will stay in one chunk for now. See how we go. Be kind of a bucket track bike with nothing fancy and a bit raw with no plastics, there is a rude looking BMW that is generally at Manfield and Taupo I love looking at but this thing will be ruder given it is not suppose to be naked.

If I throw it I will be thinking, don't bend the forks! Unless I bend something like my own forks...

I can't remember what the weak point of the motor was, I'll ask me ol' mate. He's well versed in such things and might know how to keep them reliable.

Previous owner knew how. He kept it garaged for 4 years.

The key to not having shit go bang, is to create a new "redline" below manufacturers spec that fits your budget.
I supply a race bike to a hard charger, it has a dyna ignition with an adjustable limiter that can only be adjusted by me, with the seat off. It doesn't break expensive stuff.
If it's only a track day bike, who cares about the last 1000rpm.

You drive a hard bargin mate.

I built one of the two which were run at the manfield WSB round when they came out. A genuine racekit rod broke a couple of meetings after that one.
When I built it, I was on the phone to Suzuki NZ every couple of days asking if they were sure it was strong enough....

The major weak point is rods I think. They use capscrews up from under - and the exposed threads on the rod shoulder are great places to start cracks.
The Yanks also wouldn't do cams for them as they found the valve train was weak.

From memory f-all of them came here - and few survive. Got to be worth keeping original IMO.

Second reliable source to say they fly to bits. I've got a butchered one in my garage that someone tried to turn into a street fighter. I thought about racing it, till Bryce said they're shit.

A good thrashing ..

Great thanks I intend to twist the tits off it as much as I am able. Perhaps I will live that dream of getting a knee down... Shit I best buy some leathers with pucks or it might not come back up again..

That is a good idea. I don't care about the last 1000rpm I just care about learning to corner and having a few laughs with my mates. Race day is a few of us stay at mine the night before and talk shit, then we ride out and spend all day 'racing' each other and taking shit. So I'm only puddling about with no real experience and or expectations. So I'd rather save the bike. Did you say you supply something? Not sure on the hard charger comment?? How is the limiting achieved, I'm interested for sure.

This one has no fearing, no front guard and is dereg. Still this explains why I cannot find parts for them if so few came here. Really I was after parts to convert my 7/11 1982 Katana based on Suzuki-Katana.com who did several with 1992 GSXR 750 front end and wheels. Intention being to beat it to death over just one season. I'd feel lame doing that to something worth saving but at 71,000kms and no reg I'd not feel to bad consigning it to parts to keep others alive and the bits I need to butcher my already Frankenstein 750 frame Katana (give it cannot be original anyway before I brought it).

Mmmm if it had the front end and you'd been willing to sell it I'd have brought that happily enough (and the wheels). I might have to find some grenade decals for it. Come up with some name that carries the ideas of explosive and slow (given I will be riding it). How about the 'walking stick grenade?'
