Cheers everyone, thanks for the link Del. From what I've been able to find out the exhaust systems for the oil coolers won't fit the water coolers, shame as there appears to be more choice for the former. Kristjan; don't suppose you can remember where you got your Akra from, what year is your bike, any pics?

Thanks so much Del, great photos, a real beauty! So the original stock exhaust is the problem. Read that many changed them for Yoshimura 4:2:1 I assume something to do with back pressure? You stayed with 4:2:2 (but better ones). Is there much performance difference between 4:2:2 and 4:2:1 do you know, looks like you must have had to do some work to get those blade cans to fit?

Many thanks, so taking in correction factors at the dyno 125 bhp is starting to look respectable considering its a standard engine, no mods and 23 years old. To be honest I'm finding the riding position difficult to live with, especially after an hour in the saddle so considering selling it. It was the bike of my youth, the bike I waited to see sat on the wall of the local pub on rock night, always said I'd have one so boxed ticked. Great bike, still turns heads wherever it goes but maybe its a case of shouldn't meet your heroes. Thanks everyone for your time and advice.

Thanks everyone for getting back to me. The chart says air correction SAE J1349, DJHP corrected power? Exact figures; 1-Dyno run.dpr: Max power 125.38 bhp @ 10862.3 rpm, max torque 67.33 ft/lb @ 8953.9 rpm 4-Dyno run.dpr: Max power 125.72 bhp @ 9918.2 rpm, max torque 69.99 ft/lb @ 9031 rpm Think i read somewhere 136 hp at the back wheel, so I may have lost a few horses somewhere? It's not exactly slow but I would like to get a bit more out of it, don't want to go mad and possibly mess up the engine but could anyone recommend any tuning options, and due to my limited experience anyone who could do it? As caferacedan mentioned, the exhausts look like a start, don't want to go 4:2:1 as I like the look of the twin exhausts, just something that could improve the flow and sound better. Could anyone recommend any replacements and/or specialists that can help?

Hi, I've been searching the web but sadly can't find an answer, I'm in need of an expert! I've bought a 1993 GSX-R 1100 WP, great bike but not one I know a great deal about and as they're getting on a bit, not a lot of info on them. The bike is completely standard, only done 23,000 miles, seems to have spent most of it's time in garages, still has the original twin exhausts! not had any modifications. I've had the carbs cleaned, rebuilt and balanced, then put on a rolling road. My question; The output on the rolling road was 125 bhp - stock. What info I've been able to find online suggested 155 bhp? I have heard that some bikes of the time were restricted (four plugs in the carbs), is my bike still restricted or is this the best it can do without specialist tuning? Any help would be greatly appreciated.
