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,,,

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):

If it's already happening for you, these instructions will serve to help you locate where the change was made.

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.

2000 Moto Guzzi Sport 1100 i misfires and dies

Hi, Des and the usual suspects are:
1. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a cursory reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
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. Spark plugs in bad condition or partially fouled.
4. Spark plug cables in bad condition and leaking check for spark leakage in the dark
5. Spark plug gap too close or too wide.
6. Faulty ignition coil, module, and or sensor.
7. Loose, dirty, or corroded ignition module connector at crankcase.
8. Faulty CKP or CMP, MAP, ETS, ATS, TPS, O2 sensor.
9. Dirty air filter.
10. Intake air leak.
11. Water, dirt, or rust in the fuel system.
12. Carburetor contaminated, sticky float, plugged jets.
13. Carburetor vacuum diaphragm torn, cracked, not seated or installed improperly.
14. Multiple carburetors out of sync.
15. Fuel filter clogged.
16. Old or contaminated fuel.
17. Fuel tank vent system plugged or carb vent line closed off.
18. Gas cap diaphragm valve faulty.
19. Vacuum line from intake manifold to fuel valve is broken, cracked, pinched, or missing.
20. Carburetor controls misadjusted.
21. Incorrect valve timing.
22. Valve springs floating, weak, or broken.
23. Damaged intake or exhaust valve.
24. Incompatible performance parts.
25. Control module may be in "LIMP" mode

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....
