Question about 1999 Moto Guzzi Sport 1100 i

1 Answer

Horsepower Hello all. New to Guzzis as well as this forum. But I always liked Guzzis and recently found a 1100 Sport carb I could not pass up. Beeing an incorrigible hot rodder and not beeing able to withstand the urge to go completely overboard I was wondering what horsepower can be had from this motor. My gameplan includes 49/42mm valves

Serious porting 96 or 97mm pistons 382 cams 12-1 or so compression etc. So far I have been told by a few people that 110-115rwhp is pretty much unattainable(always followed by some giggling and snickering in the background). From my experiences with other motors and based on rpm, valve sizes etc. that should not even be an issue, but then again these were completely different motors. What then would be an attainable goal?,Yes, there are always companies who will promise heaps of HP. What is never mentioned is reliability or service intervals. If you want 'Race Bike' performance you can have it, but about 100RWHP is all you are realistically likely to get from any 2 valve Guzzi engine and I don't give a toss what anybody else claims. Also using the biggest valves is NOT always the best way to get ueable HP, nor is the stupidest cam with ridiculous timing. There are many, MANY issues other than valve size that contribute to gas flow. There are also many, many things that will effect how well, or not, a cam will work. At the end of the day you are looking at a 12 year old motorbike based on a 40 year old engine platform. If you want more performance go and spend money on suspension and to a lesser degree brakes. A *good* 1100 Sport will produce in the mid eighties HP. If that isn't enough? Go buy an R6 or even a Griso 1200. If you want to play at extracting HP from a Guzzi 2V motor that's fine, but if that is the case why ask what people have done before? Use your own ideas and then compare them to previous efforts,,,

Hi, Brian and the usual suspects are:

3. Damaged float bowl o-ring.
4. improper fuel level in the float bowl.
5. Worn or dirty inlet valve or seat.

Does 2002 v star 1100 start up in gear with clutch pulled?


Not by default.

The switch is normally open and when you pull in the clutch it closes the switch. Some owners like to by-pass the clutch switch and that allows the bike to start in gear.

You can by-pass the clutch safety switch in a couple of ways. Details and discussions are available on this forum (locate the "web page" tab at the top of the main page):

It's best to use a new gasket, however I have reused carb gaskets, and it worked fine. It will probably work ok if the gasket is not torn or deformed to any great degree. I smear a thin coat of Permatex non hardening sealant no.2 on both sides. If you can get new ones, that's best.

Idel speed to low ford explorer 4.0 1998 sport how do I increase


Good Morning

While there are other reasons for low idle speed the most common is an air leak. Long story short, a hose gets old and lets more air pass than the computer knows about ... An easy and cheap way to test this is to buy a can of SPRAY carb cleaner. Start the car, spray the carb cleaner around the intake manifold, and around the hoses. When the engine has a fit like it wants to stall or does stall you have found the area where the leak is. Most leaks can be found in about a minute this way... Hope it helps you.

Front cylinder backfire


Hi, Anonymous and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.

My big bear 350 atv back fires when you give it gas?


HELLO; Have you worked on the quad recently? The reason I ask is you might check your valves it sounds like their to tight and your not getting enough flow, or you might have a vacume leak, that you can check with a can of carb. cleaning fluid spray around each sealing surface near your carb. then listen for a change in the rpm. GOOD LUCK......GREASY

Wont start without choke


I am having a similiar problem. bmw r 1100 s will only start with full choke and will die if I cut off choke or give it any throttle. This is my first bike and it has been sitting in a garage for 2 years. I took out the carbs, cleaned them and rebuilt them. I didn't find any residual in the carbs and they were very clean. Today, I was able to get the bike running and took it down the neighborhood but after the bike warms up it idles at 6K! Man... If I can't find any answers from this forum, I will probably drop it off at the motorcycle shop just down the hill from me. Any suggestions anyone? I think I will try to drain the fuel and give it new gas. But still....
