In my opinion you are beetr of with the 36mm cv, Simon Ottran here slapped a set of 38mm cv carbs on his 86 ltd. The 36mm will give you a slighlty bigger top end than the stockers of the 34
's off an old 1100. Dyno tuning is helpful, so is becoming a jetting expert via the seat of the pants dyno

I think KJ1's right, go with the bigger carbs and a stage 3 kit if you already have an aftermarket exhaust. Then slap on an ignition advance plate. You don't really need an adjustable one, though they are nice. If you get a fixed one, it'll be cheaper and you won't have to wonder about tuning/dialing it in.
I think your bike already has a set of 34's on it, right?

<font size="2" face="Verdana, Arial">Actually Karl...I had 34's on the Rg until I started the big bore. The BB is getting the 38's.

With regard to the 34's...they are nice to use because they have the same outer diameter at the intakes as the 31's. No annoying wrestling match to get them to fit. They're availible if anyone wants to buy them...

Has anybody actually fitted 36mm carbs to their 85-87 GSXR 750. If so how did you set them up.e.g Dynojet, and how did it run. The reason I am asking is that I spoke to Larry Webb at PDQ developments in England today and he told me that the article on tuning early GSXR's which was printed in Superbike magazine in 1995 and available on the internet has misquoted his advice. He recommends fitting 34mm carbs from the early GSXR1100, instead of the 36mm slingshot carbs. He also advises K&N filters/stage 3 dynojet kit, and if you feel it important,an adjustable ignition advancer set at 3 degrees max.

I had a 86 750 that had 31mm carbs on it from the factory.. I thought they where 30mm but you guys keep saying 31 so my memory must be going


I had it dyno tuned with stage 3 and a yosh pipe and I seem to remember 77hp was the peak. I sold the bike off and purchased another 86 750 but did an 883 cosworth kit on that bike and used 36mm mukuni's from an 1100. I made 108hp with that. Later I got a set of flat sides and made 112hp.

I sold the 36CV's to the friend that purchased the 750 and swapped them for him. I rode the bike before and after the swap. It was night and day. The difference in power was so shocking I almost wondered if the 31's where just worn out.... The bike later laid down 88hp when it was tuned. It picked up around 10 ft lbs of trq...

Do the swap.

All those RWHP numbers seem potentially correct. My RG with the 31's, the Hindle, and the stock air box/K&N filter was making 85ish RWHP before I tore it down...I didn't get a dyno run with the 34's...
