By the way they all have much more HP than you signature states for yours and far less weight.
Read the post again. Sig bike is my daily driver. I'm referring to my 05EG sleeper. VROD stock- not a chance in 1/8 or 1/4. Top end i loose. Sportster loses all around. If thats a 1200 buell.....I probably lose!
I will try to get the compression and leak down test done in the next day or two. I'm pretty certain it will come back within tolerance as we just had the heads off in the spring to do the gaskets, and the cylinders looked great as well as the valves had no leakage, etc. I will start there and see what the numbers show. I will post them up once I have them maybe from there we can start to narrow it down.
If you get a Cold Cranking Compression check, you can go to www.bigboyzheadporting.com and using their twincam calculator figure your static and dynamic compression. Don't forget about altitude, it makes a difference on dynamic compression. In other words, you will make the dynamic compression match your CCC reading and work backwards to figure your static compression.
They put back pressure in those stock pipes for a reason. Most bikes running straights run like **** unless their tuned for high rpm racing. Sounds like you need a good tuner and drop that sucker down a gear or two @ 60mph. 4th gear @ that speed for racing is just wrong.
I used to smoke 96's all the time with a 50K+ mile 88B just by the way I ran thru the gears.
Is your tuner 'sniffin' each pipe individually? Switching sprockets suck in the lower gears if your just cruisin most of the time.
When is the last time you really ran thru those gears and ran the twisties using the engine for most of your braking? You''ll find out real quick what that engine is capable of. My quess is alot more than your running it. Engines need a good spankin some times.
I think you need a tune. Canned maps are fine for getting you going but a tune is the way to go. I have basically the same build but still at 88", Fuel Moto gave me a map and bike was strong at low end but lacked at upper end, tried another map from dynojet which was pretty much the same. Got the bike tuned and it was a new bike, and the map wasnt far off.
