Doesn't turn more than 4500...

[KISA]

Grief at me. The engine gives out 4500 turns, and further - a cut-off. TCI-Ignitech, COP-CBR 929. I broke to myself a brain (

 

PS Sorry, with search in English at me it is bad.

[RedRider]

KISA,

 

Sounds like there is a rev limiter set in the TCI control. As I have never worked with these units, someone will jump on here and provide details.

P.S. Your English is much better than my Russian.

Silly questions maybe, but:

 

 

• Have you checked the air inlet / air filter is not blocked ?
  
• Have you checked that all four exhausts are getting hot (could be an electrical problem, or one carburettor may be malfunctioning.
  
• Does the engine operate normally to 4,500, or like a sick dog ?
  

 

There are people who know those ignition units who may give better answers, but they will need more information I expect.

 

Глупые вопросы может быть, но:

 

 

• Вы проверили воздуха на входе / воздушный фильтр не засорен?
  
• Вы проверили ли, что все четыре выхлопные трубы становятся горячей (может быть электрическим проблема, или один карбюратор неисправен.
  
• Работает ли двигатель обычно до 4500, или как больной собаки?
  

 

Есть люди, которые знают те единицы зажигания, которые могут дать лучшие ответы, но они будут нужна дополнительная информация, я ожидаю.

Pull out all four spark plugs, What do they look like????

 

One or two will most likely be black, and covered with carbon.

this will tell you which one or two cylinders is not fireing correctly .

 

Start engine " cold " and after about 45 seconds, shut it down, Feel the exhaust

pipes on each cylinder !! The " Cold One " is Not Fireing.

 

Most likely you have a problem with that cylinder,

 

Change the Spark plug.

 

Drain the Carburator for that cylinder.

 

Has your fuel filter ever been changed ???? Maby its plugged.

 

Drain, ALL 4 Carburator Bowls. !! Each has a drain hose, and Valve to drain it !!

 

Have you ever Completely drained your fuel tank ??? If not, Completely drain the tank at the Petcock, and Start with clean fuel, !!

These tanks collect water in bottom of tank, !!

 

Let us know what you find during these checks !!

I would check for holes in the carb diaphragms.

Remove the air cleaner and watch the carb slides operate with the engine running.

All the slides should move when you move the throttle.

 

[jasonm.]

if it revs slowly to 4500 and just does not pull. Then the carb diaphragms are the issue. I had the same thing on my '83...my 1st venture. If it revs in the 1st 3 gears quickly...then shutters...the TCI is bad or the multiple slides have seperated from the diaphragm. Look thru the air box filter removed and rev it slowly. any slides not moving ?

[KISA]

4 cylinders work all. For some reason on the 3rd drive it turned out to untwist the engine to 6000 turns...

I removed the air filter - everything moves.

It is necessary to come out to the route. To be continued...

I think he said that if he lets up on the throttle, it will rev to 6000.

And he had to go someplace and will be back.

Today I came out to the highway....

I couldn't overcome a boundary of speed of 130 km/h on different transfers. On the 5th cut-off in 4500, on 4 in 5000, on 3 about 6000 turns. The air filter at me of UNI, is impregnated with oil without special fanaticism. Dear, probably the problem is connected about cruise control? I never used it and I don't know, whether it works in general.

[KISA]

The problem is solved. There were no 2 jets in 2 carburetors. On dispersal gasoline filled in cylinders.

[Huggy]

Kisa I have a question regarding your 86 VR did you install the MAP sensor you purchased from Finland if so how did you install it?

[KISA]

The sensor is installed, but not connected. Slowly I look for the laptop. I want precisely setting the working range of the sensor.

While I go with the standard sensor and the factory IAP parameters. All conversations here http://www.venturerider.org/forum/showthread.php?t=40414&page=25

[Huggy]

OK thank Kisa will be following the thread with great interest. I'm not that far along with my rebuild. Going with COP's since my bike is all apart.
