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

**IronPawz** · 28th August 2016, 10:26

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.

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.
