Xvz1200 chop no spark

[CHIHUAHUA]

Hi There, I have a 1985 xvz1200 and it has lost its spark to the 2 right cylinders as you sit on the bike? my readings from my ignition coils are 3.4 ohms across all four and the pick ups read 115 ohms on 2 and 113 on the other 2. I have replaced all the diodes in the TCI as 2 were not reading any continuity at all.

 

I am thinking now that the diodes may not be the only thing on the TCI that is at fault? I know two of the pick up coils readings are a little low but still it should go?

 

has anybody had any experiences with the TCI as regards the faulty diodes taking out other components on the board? sorry I know that's a lot of questions for my first post. many thanks 83929

From past experience, once the diodes fail, other parts in the TCI are damaged. Main thing to go are the large IC's, as far as I am aware, there is no available replacement for IC's.

 

Nice looking Venture.

Good looking scoot.

Nice looking bike, lots of work must have been done to clean up it's appearance, it looks very clean.

Can't answer your inquiry about the lack of spark, but I admire your scoot.

 

It appears the stock fuel tank is still in place. However, I am wondering where the fuel filler is? Is it under the 'apparent' tank? Or under the seat? What make and model did the 'apparent' fuel tank come from?

 

Did you do all this customizing?

I would like to hear what it sounds like. Nice job.

We might be able to work out a loan of a stock TCI to aid your trouble shooting. PM me.

 

Posting some more pictures around bike would be great.

 

What is purpose of tubes below lower triple trees?

 

I am some what of a modifier myself.

Hi Everybody,

 

Just to say that the bike is up and running again as I found a breaker who had 41R Tci unit so I drove out there with the bike in my van, plugged it in and the bike sparked in to life on four cylinders! it sounded like heaven.

 

I really love my Venture can sleep again now and all is well with the world.

 

Best Regards
