  1. 1986 GSXR 750 Can't Figure Out What is Wrong

    Oil Cooled Gixxers
    One quick question - the screws holding on the intake boots were super tight, and ended up getting pretty chewed up taking them out. Is there any reason I can't just replace with a stainless steel hex cap screw from a hardware store? I know some applications need to be specific materials.

    ALSO, I still haven't actually snagged the carbs - I was told that RS34 is gonna be better for the 86 GSXR 750, but wanted to verify with you guys that that is accurate.

    Mikuni? Awesome, that is excellent advice. Hopefully they'll have info for the accelerator pump as well. This bike has been un-rideable for about 6 months now, and I picked it up 8 months ago. I just really want it to run - I'll worry about eeking out the extra 3 HP down the road.

    Mostly just looking for a solid baseline, and I can tune further from there (based on plug readings etc)

    Alright, picking up the RS34 carbs tomorrow. What are you guys running with them? Jet size / accelerator pump position? I'm hoping to be able to tune them without taking them in to a shop, but the accelerator pump tuning will be the most challenging, I'm assuming. I have Mikuni HSR carbs on my...

    Hey! Thanks for the reply - I actually ended up starting a thread for that. I'm gonna swap out the carbs at this point and will update Tuesday! https://www.gixxer.com/threads/1986-gsxr-750-cant-figure-out-what-is-wrong.840716 1986 GSXR 750 Can't Figure Out What is Wrong Sent from my Pixel 2...

    I'm alright with that. Really just looking for tuning simplicity. All of my vehicles have mikuni flat slide carbs, so I'm pretty familiar with tuning them - the CV stuff just confuses me Sent from my Pixel 2 using Tapatalk

    Awesome, yeah I'm thinking float height is the one problem that I could be missing. I found one vacuum leak at a boot on the cylinder side, but rtv fixed it up. Honestly I'm gonna try one more time with float height and plugging the vacuum, but am so ready to buy the RS carbs. I have verified...

    OOHHHH! Good call! OK, I'll plug that line. Fuel line shouldn't be an issue - you can route a gravity fed line back upwards as long as the source is above the terminus and there isn't pressure lock. Carbs are BST31ss. Needle appears to be unmarked, with the clip 1 notch up from bottom Main...

    THIS RIGHT HERE. This is why I'm getting RS carbs. Did that - Everett Powersports changed out the jets to 160s Clamps are tight as they'll go - might just be that they're not tight enough for the carbs any more, but doubtful I'll check those again - though RS carbs sound way nicer than...

    Honestly I'm completely with you at this point - particularly considering that I've already spent $600 on these carbs. Coils are new Dyna coils, here are the plugs: Sent from my Pixel 2 using Tapatalk

    Is it time to just give up? I'm considering just getting the RS36 carbs and eliminating one potential problem

    Thoughts on next steps? Clean the carbs again? Re jet? They seem in sync, but something is definitely not running right. Clean idle jets and pilot air circuit? Does it sound like 1 is off or all of them?

    Everett powersports! No afr values, they must have just done the run with no sniffer. I'd honestly MUCH rather not take it back to a shop as is. If it comes to that I'd probably snag the rs36 carbs and get those tuned. I've already put $600 into getting these carbs working with no luck

    Hey all, I'm at a loss with this bike, and could REALLY use your help. I have no clue where to go from here, and am so tired of giving shops my money. SO, the journey I have been through with the bike is: Bike was running well, but sputtered if I pinned it (unless I eased my way up to it)...

    Even if you aren't able to help, if you know of somebody in the Seattle area I'd really appreciate it! Otherwise next steps will be to check the valve lash again, and run through the carbs again

    Hey all, I'm working on my 1986 GSXR 750, and feel like I have been chasing issues with it for forever. I've resolved some, at some times, but then in the process it seems like a new issue crops up. I'm wondering if anybody in the Seattle area with a good dose of experience working on these...
  19. Spark Plug Wire Replacement

    Oil Cooled Gixxers
    Hmm ok. That makes sense. Are graphite core wires also resistor? Right now I have stock caps, Iridium plugs (which are only available in resistor type), and graphite core wire. Switching to dyna coils. If I were to switch out the caps, what are the options?

    Oil Cooled Gixxers
    Bumping really quick to ask what NGK plug caps you guys use with this? I snagged DR9EIX plugs just to keep life simple, and considering the plugs are resistor type it seems like I can switch to some NGK non-resistor type caps?
