GSXR 750 '88 Restoration Part 1

[@Getoutofthetimetrap]

I can’t wait to get going on my 1985 Gsx750 … this video is a great inspiration . Thank you Chris

[@ChrisSofos]

Thank you for your comment! I appreciate it! Your '85 GSXR is the forefather of mine and every other gixxer's. Much respect! All the best with it!

[@niconine268]

I just found your channel today. First time. It was part 14. Im at part 1 now. Im sure its gonna be really educational for me to watch all the parts on this rebuild. Thanks Chris

[@ChrisSofos]

You're very welcome! It is my pleasure. Please upload videos of your progress and share it with us! 🙏

[@Ericinos]

Enjoyed your video, really some kind of art!😎 Got a gsxr600 myself of 1992, looks a kind of simular, working on the carbs right now. Good luck man. Be safe.

[@ChrisSofos]

Thank you very much for your comment. I never worked on a 600, but as you said, the carbs should be very similar. All the best 👍

[@thegrayrider148]

Ah! It's nice to see these Slingshot Era GSX-R's receive this kind of love and attention. Thanks for sharing your project! I'm in until the completion of it.

[@ChrisSofos]

It is my pleasure! Thank you for watching my videos!!!

[@1bvm174]

I loved my 1988. I know every part like the back of my hand, even though I haven't touched one in 30 years. I traveled coast to coast many times just to race that thing. Thank you!

[@ChrisSofos]

@1bvm174 thank you for sharing your memory with us!

[@Chris-o2s9j]

Can I ask you a question. Where do the vacuum lines in the top of the carbs terminate too?

@@Chris-o2s9j Our bikes were USA spec but I only remember one line going to the airbox

My first big bike..so cool. And Rainbow music too. Awesome.

I'm happy to see more people loving these motorcycles! As for the music, I have no idea what kind it is. I just added it there 😅

[@uaxacetznab961]

I will watch all the sequence of your videos of restoration of this bike particularly, gsxr750 1988 . I want to learn from you. I want to ride my bike someday jeje 👍

[@ChrisSofos]

Thanks so much for your comment! Always happy to be of help 😊

Keep up the good work

[@ChrisSofos]

@bradlybaldwin9564 I'll do my best. Thank you very much!!!

[@rsbharley4766]

Excellent video. I am looking forward to your build, as I have a 1989 GSXR750K and it needs more work than your bike. Think I am looking at a top end rebuild as well as all of the normal things of a bike of it's year. Ride safe Cheers

[@ChrisSofos]

Thanks for your comment! I'll resume rebuild sometime in October, as I'm overseas for holidays at the moment.

Nice video , i have a 1991 750 and going to restore it this year ! Have the bike since 2002

[@ChrisSofos]

One of my favourites as well!!! Nice to know there's people like you out there, looking after these legendary bikes!

[@danielmayerus9260]

Yes i realy likes these bikes , never going to sell mine . Do you have a good shop where i can buy the bearings and the other parts for the engine ?

[@ChrisSofos]

@@danielmayerus9260 the shops I buy my parts are cmsnl.com and megazip.net Alternatively you can look up the part codes there and look on eBay as well.

[@danielmayerus9260]

On megazip i see the color codes for the bearings , thank you very much for the help

just picked up an 88or a 90 not to sure and excited to dive in!

Congratulations on your purchase! The '90 model has up side down front end. The previous models have the normal front.

[@ChrisSofos]

I love that color combination too my friend!

[@adamrice2847]

The handling on these bikes is kinda scary!

[@ChrisSofos]

To me, especially this model was absolutely perfect! When there's brand new tires and a good tarmac, the knee will scrape the asphalt. I felt perfectly safe throughout riding it.

[@christopherwatkins9900]

I have a 1989 Gsxr 750 slingshot I can jump it off and it runs strong But when riding it it cuts off and acts like the battery is dead is there any pointers on what it could be

[@ChrisSofos]

It can be the battery (in which case you'll have to check it and check if it's charging properly). It can also be fuel starvation. These motorcycles have no fuel pump. They have a peacock that operates using the engine's vacuum. If that system is failing, then no fuel can go to the carburettors. Hence, the problem. I hope this helps!

[@mikeellis5714]

Great work, where did you your parts from.

[@ChrisSofos]

@mikeellis5714 thank you! Some from ebay. But if I want brand new parts go to www.megazip.net

[@henryparker6931]

Hey Chris which front stand do you use for the Gixer? Thanks

[@ChrisSofos]

@@henryparker6931 I bought a La Corsa years ago, and I'm very happy with it

[@SS-yn4oc]

I used to service my 1985 GSXR myself, using the manual, and remember taking the faring off. Was a great bike, except for the frame, that was made more for the racetrack than the bumpy roads. Too many tank slappers.

[@ChrisSofos]

I think I know what you mean 😅

[@MHLivestreams]

Add a steering damper, I got a really good adjustable one from china for about £25, seems to be good quality too, ohlins are seriously expensive for what they are. Give it a go.

[@uaxacetznab961]

Hi there ! I love this bike to , i got one exactly as yours but I have a problem with the engine, it is stucked , doesn't move and I've search in other videos and it seems the problem is with the crankshaft bearings and the conecting rods bearings too. My problem is that the conecting rod numbers to know the color of the bearing was ereased and I don't know how to proced. Worst thing is I'm not a mechanic !!

[@ChrisSofos]

I'm not a mechanic either, so don't worry about that part 😆 It seems that your engine has seized for some reason. Maybe it was left without oil? If that is the case, I don't think it's worth repairing it, as you'll need a new crankshaft and camshafts as well. The cost will be too high!!! If your engine is not seized and the problem is elsewhere, then it might be worth repairing it. Suzuki has another way of checking the sizes of the bearings (crankshaft and con-rods) in their manual. I'll check it out and if so, I'll make another video to explain in detail how and what.

[@uaxacetznab961]

@@ChrisSofos I'm glad you answer so quick. I apologize my english may not be very good ja! But I'll do my best. I'll pay atention to the video you mention will up load. The history of me having this bike is a little as a headacke jaja but I insist on it but it seems that at the end one has to do the job.

[@uaxacetznab961]

@@ChrisSofos 2 years ago I took the bike to the workshop because the engine couldn't started , finally it did but the mechanic sugested me to replace the cranckshaft bearings and the con rod bearings. They finally put the same bearings it had, just polish them and put them back. I remember 3 of the conecting rods move +/- easily but not the 4th one. Once the motor was finaly armed the mechanic tried to move the crankshaft with a wrench but could not. The proces was done with out oil.

[@ChrisSofos]

@@uaxacetznab961 Hmmm... that's a shame they did just that! It seems that you may need another engine. From what you tell me, I don't think it was just the bearings need replacement. Find another engine to put on and keep this one as spare parts (covers, valves, rocker arms, etc).

[@uaxacetznab961]

@@ChrisSofos ... I'll think about it. Some one around here has a 750 engine but is a Katana model. I'm going to see if it fits into this one 🤷‍♂️

Hola tengo un problema con una yamaha fzr exup 1994 el problema es que la moto no acelera falla a 1000rpm pero luego apago la moto y acelero y sube a 6000 rpm luego baja otra vez y empieza a fallar estan los 4 cilindros encendidos recien le hice el motor no tiene valvula exup se la eliminaron porfa me puede ayudar ?

[@ChrisSofos]

The fact that the Exup valve has been removed can affect the engine operation. Despite that, you need to check first the condition of the spark plugs (check if they are clean and the have the correct gap). Then check if the rubber inlet manifolds are in good condition and tight, so there's no leaks. Then check the carburetors. Are the carburetor's jets all clean? Are they the correct size? Are all the passages clean? What is the conditions of the needles? What is the position of the needles too? The vacuum diaphragms? Any holes on them? You need to check all that. And the best way to do it, is to remove them and inspect them.
