Last weekend I picked up a new to me 99 750ss 1/2 fairing with 12500 on the clock. The last owner had the bike for 18 months and put on 500 miles. Only 1500 miles had been put on by the previous owner in 2 1/2 years. So a lot of sitting and not too much riding. New Michelin Power tires are on the rims. Bike is completely stock except the seat which is a Sargent cover and base.

I have changed the engine oil and filter, cleaned the oil screen, replaced the cam belts and tightened to a 5mm allen wrench passing through, new spark plugs. I have checked the valve clearances and they are in operational range. I have 5.1 fluid to replace in the front, rear, and clutch lines to be done this week. I have given a really good scrubbing to the bike and started on detail work like removing all the road tar and degreasing the engine.

What other if any service work should I perform to make this bike reliable as a daily rider? I was thinking perhaps shock/ fork oil change. If so what weight range. I am 160lbs.

I have a couple of issues.

The bike does not like to start every time. I have read about coils helping. Does this really work or is there some better cure?

The trip odometer does not work correctly. Sometimes it will count from 0 to 19 miles and then halfway go to 20 before snapping back to 19. Others it will not increase at all. Is there any fix for this? I would like to keep easier track of when I will need fuel. I will not be able to ride every day so not being sure how much fuel is in the tank can be an issue at times.

I want to get a set of slip on mufflers. The dealer can no longer get Termingini from the factory. I have heard a set of Forza silencers and they sounded good. What else is available that has a similar sound. I prefer carbon fiber for the appearance. Is the factory remapped computer good or is there a better option.

I have been a big fan of Ducati for many years. Dad owned a Monster many a year ago and really enjoyed the sound and the few times I got to ride it. I have been riding 25+ years now and have had various styles of bikes. Last ride was a Buell XB9R. Also have ridden/ raced sport tourers, standards, naked bikes, dual purpose, and dirt bikes. Mechanically I race go-karts and build them and the engines for them. I have no problem disassembling the engine to cut the valve seats or replace crankcase bearings.

Thank you all for the information I have already read on these forums. It allowed me to make proper adjustments on the cam belts. The old ones I took off were definitely too loose.

A nice short first post. :)

Your '99 is fuel injected so it shouldn't have the clogged jet issues that would be likely in a carbed bike that sat around as much as yours apparently has. Though I wouldn't completely rule out some clogging in the injectors and/or other fuel related bits, it is fairly unlikely if the bike generally starts and runs fairly well. Check the obvious stuff, particularly battery condition. the voltage regulator/rectifiers aren't the best in these beasts and can both undercharge and overcharge, either way causing your battery an untimely death. Does it always crank over quickly but just not start every time? As for coils, yes they make a surprising difference. I put a set of Dyna coils on my 900SS SP, just 'cause it was the last mod on my very basic list (gearing, FCRs, pipes, seat, coils) and didn't really expect any significant difference. Well the difference was shocking - pun intended - with the bike springing to life much quicker at the merest flick of the starter button and definitely more low-end snap. It now does easy 2nd gear roll-on wheelies. A good mod, IMO. Anyhoo, give us a bit more to go on symptom-wise for your sometimes non-start issue and let's see if any other ideas pop up.

The 750 is a great bike... hope you enjoy it! Regarding the difficult starting: You might try a new battery. My 750 sport had starting issues until I replaced mine.

By the way, I've had my eye on an XB12R, or possibly a CG. I test rode them a couple of weeks ago and I really liked the bikes. I hear they've improved on their reliability too. Got any "world-worn" advice on these brutes?

Mxwinky... Do you think the Dynacoil upgrade will help a fuel-injected bike. I've been thinking about it myself but it's been a low priority, especially since it seems that the upgrade is aimed at the carb models.

Congrats on your first Duc!

It sounds like you've done about all you'll need to do to the bike for some time now other than to track down the starting issue.

I had a 750 sport myself for about a year and a half before stumbling upon my 900SS that I have now.

Put about 15,000 on that 750s without a single issue and have a hair over 36k on my 900ss now.

Not a single mechanical issue thus far on either of them.

I commute as well as do track days. My husband and I try to get 2 week long trips in a year (Colorado, Tennessee, or Arkansas). So I'm not exactly easy on the bike.

It's never failed me and I'm constantly left with a smile on my face at just how light and flickable the thing is. The motor is like a tractor, it just keeps going.

And no, I've never once had to have a single valve adjusted. I purchased the MBP collets for the bike and they've been sitting in the tool box for 25,000 miles....wasted money really...lol I was going to have them put on IF the bike ever needed a valve adjustment, but it's just never happened.

One piece of advice I will offer, since valves are in spec, only bother checking them every 12k miles after the first 12k miles on the odo. I've had this suggestion from every Ducati mechanic I've ever talked with and thus far it's held true.

On these 2v air cooled motors, they've found that if the valves are in spec within the first 12k miles, they're likely to never go out of spec...but then again, most Duc owners don't put a whole lot of miles on their bikes before parting with them either. :)

Enjoy and welcome to the sickness that is a Ducati.:abduct:

XB9R thoughts

The 12 would be a much better bike than the 9's. My main complaint was the 9 just lacked a little umph for the chassis. The gearboxes are very slow and deliberate as they are straight off the Sportster. The chassis was the best I have ever been on. It was also very comfortable for my 5'8" 140lbs. I did not have a single issue with the bike in 1 year 6,000+ miles of riding. The suspension was very tunable. Idle and even transitional rpm had quite a few heavy vibration areas.

I originally ordered and purchased the bike to be a hard core race replica. The chassis met that requirement the engine did not. I think I would have been happier with the Triumph TT600 that I was also looking at during that time.

Cliff notes:
Awesome chassis
Needs better engine

Starting is one of two options for me so far.

One engine cranks for about 1-2 second 5-6 revolutions minimum and then fires up. This is stone cold in the morning or after a 30 minute ride and stopping for fuel. This is the normal way it starts so far. It just takes a lot longer than it should to fire.

The other has only occured when stone cold. It will take 20-30 seconds of cranking to get it to fire. This has happened three times so far (in 1 week). Same procedure is still used as normal it just wont fire. I have to resort to full enrichement, wide open throttle, and crank till it starts. This has worked on the second and third times it did this and fired up. It took me a couple of hours to figure it out on the first time. Had to put the battery on a starter booster as it had run down the first time trying to start so many times. On the first go around starting fluid in the airbox and straight into the cylinders was tested. Also with the plugs out of the cylinders and grounded there is no visible spark. This is why I am really interested in coils.

Battery is of unknow age. However it looks cleaner than the surounding parts so probably has been replaced. It had plenty of acid to the proper levels. It held 12.5V so was well charged at one point.

Does anyone know the proper output voltage at certian rpm's for testing the regulator/ rectifier?

JDuc- thanks for the update on valves. This is good to know that once broken in they last a long time.

gomura- is the stator/ rotor and coils that same on the carb v. ie. bikes? if so then coils will be a help on the ie. bikes also.

mxwinky- I will drop a bit of methanol in the tank to clean up any water that may have condensed, I will also put a bit of injector cleaner through the system. If there are any other problems I may just dissasemble and clean them.

I will also get out the bore scope and see if there are any problems with the bores and/ or piston crowns effecting compression. What should compression be for this engine?

Any ideas on who makes great sounding slip-ons?

I'll have to check on the stator/rotor but I'm guessing they're the same. As for the exhaust. I have carbon Arrows on mine but I don't know if they're still available. If you find slip-ons for the FI 900ss, they'll fit on the 750. At least the Arrows that I got were labeled "900ss/750ss". By the way, I see that Motowheels has some Sil-Moto slip-ons for the 750ss. When I first started looking for slip-ons, these were often sited as the best ones for the supersports. They were too pricy for me at the time so I didn't go for them. You might want to check them out.

I have these on my '00 750ss and they sound great. Leo Vince makes them in full system or slip-ons. I ordered mine without the logo although the dealership screwed it up and would not return them.

IMO, I'd go logo-less as the logos have faded on my bike over 5 years although the pipes still look and sound great. Lots of growl to them and they sound wicked upon downshift, but not overpowering.

replaced the cam belts and tightened to a 5mm allen wrench passing through,[/QUOTE]


Ill believe you want to check the vertical cylinder with a 6mm. I was told this was due to heat, can anyone else verify.


EDIT: Sorry couldn't wait for a reply

This link covers it.

+1 on possibly changing the battery to get it to start better. Easy to test if that is the problem - jump it to your car battery (car off) and hit the starter.

As for cans, the 99 doesn't have cats, so coring the stock pipes is easy. Not sure if the aircone core kit is still available. If so, it is a nice, easy, cheap mod that gives same performance and similar weight to aftermarket slip ons.

it should start fine. maybe try a few key on/offs to cycle the fuel pump a few times to see if that helps before you hit the starter. Otherwise try to find out what's wrong with it. slow to get fuel pressure? bad idle mixture setting? corroded engine temp sensor connector? lots of things can possibly influence it.

the dp ecu works well if you can get one, or get the std one remapped to suit some pipes. forza is fbf's brand on silmotor mufflers.

get the forks resprung to suit you weight with linear springs if they don't have them std - that will make a difference. i recall those bikes seemed to have a lot of rebound damping - maybe lighter oil. ask a suspension specialist in your area.

the trip odo issue might need a specialist to cut the speedo apart and fix it internally. that's about all you can do.

How would you core the mufflers? Is it similar to what the H-D guys do? They just use a hole saw to cut out the center of their pipes.

It did not make any noticeable difference when I had it hooked up to a 100amp starting box. So I think the battery is ok. Maybe it needs the bigger cables to it like I have seen advertised.
