Another Newbie

So yesterday i finally got around to refitting the airbox on the Jota,not a big job in the scheme of things but an achievement nevertheless, and it took a little fettling to get there.

Here's where it starts...............................

looking battered and bruised and held together with numerous bits of tape, the airbox had clearly seen better days,the back panel was heading for the bin but the shell could well be saved.













Taking it apart I could see that the baffle plate had been wrongly assembled and was putting extra pressure on the outer casing which may account for some of the cracking. ::)

First job was to bond these back together, i used a strong solvent weld adhesive used for pipes and guttering to do the job.







To reinforce the repair and with the 180's vibrations in mind a fibreglass inlay was carried out.





and primed




after a little more fettling on the outside a finishing coat of black was applied.













With the internal plates refinished and a new filter fitted,she was ready to go,......On the advice taken from here,the baffle plate would be left out.





Now complete and with a new back plate and rubbers.







The Airbox is finally back where she belongs








Happy days...........time for tea  (coffee)  (thumbup)










 
Looks really good though you might want to remove it until the carbs are back on else you may scratch it up again... ::)
 
Spray painting in the living room?  Wasn't the missus fuming? :D  Airbox does look presentable again.

For heavens sake, omit the bottom baffle and let the engine breathe!  You don't breathe through a straw, why force your engine to?  Guessing you're running Jota pipes, the extra bit of intake noise won't be noticed...

or at least turn the intake of it backwards. I had the same rubber hoses on my 1000 SFC airbox. In heavy rain, the bike started to lose massively power and white smoke came out of the exhaust  :o I was thinking of having a major engine failure, but no - as soon as I entered a tunnel, 2 seconds later power was back and smoke was gone. exiting the tunnel, I found myself in heavy rain again and the problem re-apeared...  :o

What happened was that water was passing between the cylinders and also around the cylinders and was ending up on top of the engine. the drain-hole wasn't capable of getting rid of it fast enough and so the engine sucked in the water and tried to "burn" it...

stoped at the next gas-station, removed the rubbers and also the now totally wet airfilter and bike was perfectly running afterwards. Replaced the filter as I was home and all was good.

Shit: thought that was a connection to the breather or some such.. can't believe they expected the bike to breathe through that pissy little hole.. :o :o :o
 
Thanks for the comments and advice Guys, (thumbup) the wife doesn't know I bake my switch gear and calipers in the oven either  :D lets just keep it to ourselves shall we.

Funny i didn't see that bottom plate as a baffle,but i must have read your mind Piet as I was looking and questioning the size of the inlet yesterday......Now its fitted i am going to leave it in for now until I have ridden the bike and it all checks out OK,but it will be on the next list of fine tuning......i will look at turning the hose around though,thanks for the tip Laverdalothar. (goodjob)

Cam chain still to be adjusted and i wont forget the lock nut (thanks Chrisk for keeping an eye out) and the carbs are now fitted with the airbox removed first for access (thanks AndyW) even then it was a tight squeeze having to feed it around the breather hose.

The more i work on the Laverda the more i am loving it but jobs seem to take a lot longer to do with a higher level of thought process going into each one, from routing cables to fitting the exhaust its all very tightly engineered but the character of the bike is now growing on me and i can't wait to ride her.

So today we finally pushed the laverda back out into the sunshine for the first time since getting her and i am pretty happy with how she's looking.........After getting through a long list of jobs during the winter months, there are but a few more to do, mainly checking over and some fine adjusting.

Yesterday saw the first start up,followed by carb balancing and timing checks she now starts on the button and is ticking over nicely.
Clutch adjustment has to be fine tuned,I am not familiar with Laverda gearboxes but presume they all clunk into first as do the big Zeds?

I will get more of an idea and some feedback when i ride her,and also find out if i have adjusted the eccentric cam properly. ;)

A little bit of work to be done on the sidestand fitment (as expected) I wasn't quite sure how it was going to sit with the center stand but it shouldn't take much to sort it out........Stand works brilliantly though.

This forum has been great source of help and advice and i am thankful and appreciative of it all. (goodjob) to all who contribute.

Hope you like her..........Next big step.....Test ride 8).....Oh Lordy.




 
dont go to the ASGM tomorrow with that bike because Nickdav7 will probably steel your front mudguard with its correct stripes!!!
and while he is at it, I will nick the cooler hoses and replace his purple ones with yours

You have done a great job your 80 Jota looks fantastic (nearly as good as an 81 Jota???)

It has to be said the fairings on the '80 Jotas look a lot better than those on the '81 models.

Cracking looking bike!
 
Mine needs nice low idle, not above 1200 or it makes a hell of a noise going into 1st from neutral.

Just remember when riding her that bike will be very happy in the 5000rpm range and so will you!

Plus one a fantastic job looks pretty as a picture and dont worry about his 81 Jota dig, I for one reckon the 80 Jota's were more pleasing to the eye. Now if only I had kept mine it was a great bike, got me round Aus and all it did.
