big block oilcooled gsxr750 motors

Gotta pic of that stand Clive?
Please!

[03gixxerpilot]

don't have a camera at the moment, but will do my best to get one and put up pics asap

[stevo]

camera over here clive........

[03gixxerpilot]

ok stevo will have to try to catch you tomorrow,

more progress, i have pulled down the top end and barrels of the long stroke motor and the bottom end looks to be in good nick, i still havent decided if im going to go the whole way and check the bearings etc but i am thinking that it would be a good idea. also give me a chance to inspect the gearbox closely as well. still waiting on the short stroke motor, but that should be on its way this week.

[03gixxerpilot]

A couple of photos of the $0 engine stand build, worked a treat,

the motor in now a set of bare cases, i wasen't going to pull it down to bare cases but i found some dirt in the dowls that locate the barrels and was concerned about the internals of the motor. In general it was in good nick, however, the main bearings were a little worse for wear, so they will be replaced, the big end bearings look to be in very good nick, so i will check the clearence on them and if that is ok i will reuse them. this has also allowd me it inspect the gearbox, and shift mechinism, amoungst other things, and have found there to be very little if any wear at all. All in all it was worth pulling the motor down to bear cases.

Nice one...that'll save your back Clive.

[latheboy]

So how is this going, have you got much else done.... tell me tell me go on go on tell me

[03gixxerpilot]

nar mate hven't done much at all, i have moved and every thing is all over the place, i will be sharing a workshop with a mate, and we setting it this week, so hopefully i will be able to make some progress on it, i have to get some pistons befor i can go further, but i have already decided on the ones that i want, it is just a case of getting them, but i have just started a new bussiness and it is taking a lot of my time, (i'm new to owning a bussiness) i am still getting a handle on things.

hopefully next week i will be ording the pistons.

I'll keep you informed on how it all goes.

[Tone]

Phew...glad to see this is still going Clive,thought you were keeping it all a secret there for a while.

[03gixxerpilot]

No, no secrets, just delays, thats all

[DCRacing]

Clive keep it up mate, i am circut racing a L model and i had heard that you can get them out to about 955cc. but i am not too keen to push it out that far, but if i can go down the path you are i will give that a shot. i already have a spare set of L model cases, looks like i just need some barrels, can you use the L model head on the barrels? and what about head work are you looking to do if any?

[03gixxerpilot]

DCridedays i am no going out as far as that (955) for exactly the same reason, and because i want to be able to use as many standard off the shelf parts as possible (avaiblity and cost). As for heads, basicly you must use the heads of the short stroke motors (748cc) or of any of the oil cooled 1100's, i have both a 748cc and an 1100, the 748 head is a standard one but the 1100 head has a lot of work done to it (proted and flowed etc). I am planing on using the standard 748 head as a base line one the motor and once dynoed and tested i then plan on working that particular head in stages up to the standard of the 1100 head to see what gains can be gotten out of the motor.

Hey Gixxer, got any updates ont he motor build?

[03gixxerpilot]

no not at the moment i am wotking on the chassis for the project at the moment
i will be sure to post up any progress as i do it though

[latheboy]

Hey Clive .. its been 2 months any updates?????

[03gixxerpilot]

as in the previous post to the one you have just put up i am still working on the chassis at the moment, for every ones info the chassis now has a vfr sssa installed and i new 06 R1 front end for it. i am how ever putting aside the $$$$$ for the piston kit and machining that will need to be done, i am getting close to having all the dollars needed.

[03gixxerpilot]

been thinking about it since i replyed to your last, and ............................................


Thanks for the kick up the ass i have decided to make room in the overcrouded w/shop and make some more progress on this project,
what good is a chassis without a motor anyway. LOL

[latheboy]

haha ...

[03gixxerpilot]

DC and latheboy just a quick up date on the build, last night i revuied what i have researched so for and what else i would need to buy, get made to make more progress on the build, with the current combination i have not thought on base and head gaskets, and sice the size bore that i had decided on is not one that is standard i would have to get them custom made for the aplication, the whole idea of the build was to have as little amount of custom made parts as possible, so more research was done last night and today, with the outcome being a new combination for the build, it is not that diffrent form the original idea, i have gone to a larger piston, ie 76mm (which is 3mm ove the orignal gixxer)this allows me to use standard suzuki gsxr 750 base gasket and a standard gsxr1100 86-88 (1052cc)head gasket thus making the only aftermarket part a spacer plate for underneath the barrels.

so a brief overview
Suzuki gsxr longstroke big block (now out to 883cc)
suxuki gsxr750 longstroke bottom end (85-87 90-92 749cc) ( recomend the late model conrods )
suxuki gsxr750 shortstroke barrels (88-89 models 748cc)
Piston kit:
Kawasaki ZX9R (98-99 00-03) +2mm pistons
im using wisco part number R923 (76mm)
Gaskets:
base GSXR750 ( shortstroke 748cc)
head GSXR1100 (early model 1052cc)

[03gixxerpilot]

the nest question to look at is what head to use, i have the standard gsxr 748 head to use, i also have a ported and flowed head to suit a gsxr1100 (was dynoed at 195hp on an gsxr taken out to 1216)
what dose everone think of the two options, good and bad for both
