bloodhound ........oh god....went through all this on 650rider till I was blue in the face.......would think that most don't care or don't want to hear it again.....
Could cover maybe some important things I found for you..........
1. Oil cooler may help a bit........but the cylinders are the hottest place and the oil cooler won't effect the heat there what so ever....
2. Lowering the R/S hotter cylinder temperature will reduce the cylinder temperatures like 20+ degrees ...........
3. Using wind directing wings under the front forks and on the sides to direct the air over the cylinders lowers the running temps say 15+ degrees...
4. Good highway gearing probably helps some too.........
The combination of things is where it's at.........to reduce overall temps to say 225-230 max running cylinder degrees at 90 degrees ambient..........instead of 260-270+ or so normally found........ouch
I also reduced the compression to 8-1......lost just a bit of high rev power but everything else was a benifit...reduced ratcheting and smoother with reduce tenseness and no engine noises at operating temperatures........has to increase engine longevity and power loss when the engine gets hot.........at the end of a hot day it has as much power as it ever did....definate good trade off for me there for the summer............
curt698 .........same rpm...........may induce more vibes due to increased piston weight and or more compression....never ran a 750 on mine....I am a fly weight and old....already had all the powerhouse motorcyles I could stand......just a cruiser guy now...and mine will go faster than I care to go anyway....being 63 and all..... and still in one piece after 50 years of riding....
