I saw that ducshop had the hi-comps for a little over $600. Not bad, now if I can find someone I trust to do the work. Our rulebook up here looks a little sketchy when it comes to pistons, stock, stock, stock. But I doubt they would check even if I podiumed every weekend. I've heard of other people using them so it must be ok.
I don't think anyone has the time or money to challenge and tear-down another competitor. If you are anywhere near Flrida then I recommend MotoCorse in Ft Lauderdale becuase the squish are must also be checked for proper flame travel, at least that is what I was told.
Do you have a slipper clutch installed. I hear the one off the 620 drops right in and I can think of a few times it would come in handy under heaving braking into haripins. I'm in the northeast. BCM in NH has a good rep but Bruce Meyers is no longer there. I have a local shop with a Duc tech. Piston drop in shouldn't be too complicated. Can I really expect 10+ ponies? I want to get down to daytona or homestead for a track day one of these years. the WRA GNF would be fun to do, although it was in Atlanta this year. Light grid and if you win your national champ. Like those odds.
Sorry for all the typos on my last post. I must have been more tired than I realized.
No slipper clutch but Moto Corse has been working on one by using the 900 crank and gears. I am not sure about the 620-must look into it. I have no idea if a slipper clutch would be helpful to me. I have never ridden with one and I am old school in using clutch control.
Dropping in the pistons also require shimming to set the squish for those pistons. Mine produces 86 rwhp on a Superflow dyno at 8700 and still climbing but it is tapering off by then. I think it produces 84 rwhp at 8K. So yeah, you can produce 10+ more hp.
MotoCorse is also developing a cold air intake and claim a good response in HP all for around $300.
Last race of the season is in a couple weeks. December 6th and 7th. I will be attending the Penguin School on Friday 5th at Homestead. Then there is a trackday in January with Florida trackdays that I may do also just to learn how to ride this beast.
Ok, share some of your suspension set-up. I bought mine as a salvage titled bike that had been crashed. I found the fork seal leaking and the tube was damaged. I went to my parts source (ebay) and found a 1000 adjustable fork with reported Ohlins internal. I have the stock rear shock but I know of others that have had suspension work done by GMD. With their bikes the rear Ohlins shock has been modified to be taller making for a taller rear height for the bike and of course the front to match.
I am currently on stock geometry and it seems to push through the corners, or it could be me just having no confidence in the bike and running wide on exit.
I went the GMD route. Forks revalved and resprung. Plus geometry and the ohlins rear with the extension to raise the rear. I was draggin my headers before I did the geometry plus the bike will turn much easier with more ride height as it "tips" into the corners. I think the ride height is critical as you know what a freight train these things are. I find when I get lazy and sitting back more instead of climbing all over the front my times get worse and the bike doesn't like to turn. I was thinking about doing homestead with the penguin school. Just to get one more day in before we start skiing up here. The layout looks a lot like Loudon and if their renting their usual fleet of 900's then at least I would be comfortable. My goal is to do one different track per season aside form racing. The air intake mod sounds interesting. I have a chopped box with ITG filter right know. The map I got from FBF with the PC. Seems to work well. I had my biggest drop in times this past season with moving to race tires. Bridgestone 002's from Mich 2cts. Lots more confidence in grip and lean angle. Hooked up everywhere and I podiumed my first weekend on them. Hope there are more to come.
Congrats on the podium. I have used Bridgestones from the very start. I only race on slicks due to all of my classes are SB rules anyway. One thing that not many peaople know, slicks hook up pretty good in the rain, even won a race on them in full wet conditions.
It definitely takes a bit to get it turned and so it goes, I will need to find that Ohlins shock and extend the height. I am starting to drag the fairing and I am not leaning it yet.
Thanks for the info. I think you will be satisfied with the BT003 or even the slicks if you choose. I set my pressures to 32 hot. Works out about 26-27 cold. One of the 600 SS Experts here found a best pressure of 30 hot.
Where? In Homestead Florida at the last race of the CCS Florida region. Starting from the the second row, I made it to second place by turn one. By the half lap of the first lap I made a pass for the lead and kept it throughout the race. I also made it through most of the 125GP field where they started in the first wave. Caught up to the second and first place riders of that group on the last lap.
I also entered the GT lights class where it is predominantly sB Ducati 1000, Bimotas, and SB SV650. I started on the third row and made it to third by the end of the first lap. It was only until the 5th lap that the faster Ducati Superbikes were able to catch me on the straights making their pass. I passed a few back before we could get to the next corner but the power difference was just too much. Ended up 5th and in the money.
Nice Mark, sounds like your coming to terms with the 800 already. I sometimes wonder what people are thinking when they hear that rumble of the 2-valve come past. Like, shit that guys on a duc. Or, dam how does he pull away like that. I can't wait to get back on the track. Always thinking about breaking markers and how can I get on the throttle sooner. Trying to trail ride as much as I can for training, but tough on cold, 20º days without studded tires. My goals for next season are at least 3 race weekends, including 8 track days and another on a different track, probably New Jersey's new track.I found a shop up here that has 4 sets of the hi-comp pistons for the 800. So, I'm gonna hold of till after the holidays to make the purchase. Also thinking about replacing the fork oil. Just love having needless ways to throw money at the duc which is my excuse for not buying another bike.
That race that winner takes all is the CCS race of champions at Daytona. Couple guys from up here won there class. Its in RR world every year and latest issue.
This past weekend was a major advancement forward coming to terms with the Ducati 800. I attended the Penguin school and listened to what was said. I then ascerted myself and my riding and improved dramatically. On stock geometry I was able to put together a good run and improve my times and my racing. I must now learn to be consistent with this bike.
I spoke with Al at MotoCorse in Ft Lauderdale, Fl and it looks like my next move is either a dry, slipper conversion or a fresh air intake.
If I were to do it again I would probably hold off on the HC pistons and do the intake instead. My motor is the HC pistons, low budget cams, porting and the PC to yield 86 ponies. My buddies bike has stock pistons, low budget cams, fresh air intake and PC to yield 83 ponies. There is a difference in $1400 in pistons and porting and $300 in the intake. I vote for the intake.
The intake was developed by the boys at MotoCorse. I've seen the dyno sheets.
As far as suspension I am gonna stick with the stock geometry until I start dragging parts. It seems to turn well and there is no fading with the short sprint races. Finally mounted the Marchesinis and they look great. another great job from MotoCorse.
I would check on the dry slipper mod. I understand the wet slipper off the 620 drops right in from a reliable source. The intake mod sounds cool but I'm gonna stick with the hi-comps. They're on sale for $675 and since I'm gonna have the valves and belts done in the spring I can have them dropped in at the same time.
It is friggin cold up here and we're suppose to get a foot of snow tonight. You guys got it made in the winter. Wish we had track days year round. I wouldn't have to go through the reintroduction to the track come spring and just keep dropping my times.
Happy holidays, may the gods of speed be kind to you this holiday season.
