Here's another one...

Ride the piss out of it!

Who said that? 

 

I've seen that one before!    

Haha i heard that i few times now.Well yesterday i did a new try to check the ignition timing ,but i could not get the timinglight to work on cyl 2-3 again .It works at idle ,but not when increasing rpm to check the advancemark.Not sure why ? maybe the picupcoil for 2-3 is defect ?

I adjusted the timingplate a little clockwice and the 1-4 is now spot on nr 2-3 is a little out on idle .Will try to check more today ,but not happy with letting the bike idle and maybe glacing the bores so i may just ride it more before more checking

I now have got the timing/strobe light to work on cyl 2-3 at 2500rpm. It was just to put the timinglight to the plugwire to cyl 2. I read somewhere that on this type of coils one ht lead is positive and the other negative so maybe that was the reason the light did not work on cyl 3 ht lead. I thaught the left pickupcoil needed a little adjustment since i adjusted it back in september when i used a test bulb to set the timing and just a day or 2 after that one coil melted.So the main timingplate is now turned clockwice back to the setting i used when a coil melted. After what i have understand the coilmelting has nothing to do with ignition timing??  So now both sides are spot on timingmark at 2500rpm.
Yesterday i was for a ride again and it was only about 3degree celsius so i had to have the choke on for the first 10-15 minutes  or else it almost stopped that is not good because it both sot down the plugs and may wash down oilfilm in the bores not what i want when running in the engine. The bike almost stopped at one time and i guess it was because of fouled plugs.
Later checked the plugs and they was sotty, but bike runs good. I then replaced the plugs .Im hoping for varmer weather so the bike dont need so much choke and i can take a look at the plugs again.After replaced the plugs an engine was fairly warm it started popping a little from exhaust .i knew cyl 2 downpipe was the hottest so i turned the micture screw on that out one quarter and after that the popping stopped. I think it is a little lean on all 4 now so will later try to adjust the mixturescrews a little more out. I had set the mixturescrews same as before  overhauled the carbs this winter,but
since  replaced them with new screws i think the settings dont match now , also did a valvejob so that also make things different i think.

The engine has now run about 120miles and i checked for oilleaks and found one little leak on the underside of alternator cover. I bought new gasket and was planning to replace that and in the same time take the startermotor out and fit new brushes and o-rings.I suspect that the pieces of the o-ring i found when taking engine apart is from the startermotor since i have replaced almost all other o-rings in engine but none was damaged.
I drove to a parkingspot planning to have a good time eating donuts and have some cozy wrenching in the sun.That turned out to be a stressful event instead =)

Quick question because im to lazy to go down in the garage to check.Is it possible to take the startemotor out without removing the chaintensioner ??

Yes!

Okay thanks Zed1015.  The reason i going to take the startermotor out is that im trying to find out where the pieces from a O-ring i found when taking the engine apart is coming from.
I suspect it is from the startermotor since i replaced almost all o-rings this winter and none was damaged. When i had the alternator cover off i can see that it may not be from the startermotor because how can the pieces get into engine that way??. I think that a PO has taken the startermotor out and the o-ring was damaged and replaced and the pieces fell off.
So when i lifted the barrels off there maybe was some pieces that dropped down into engine since they where laying on top of the crank. When i took the sump off i did not find anything.I also filtered the oil ,but nothing in the oil.
When i was going to put the barrels on i found some more pieces laying on top case under the cover from startermotor.

Did not get the startermotor out ,i could have if i had wrestled it some more but since i saw the o-ring was intact i just pushed it back in .The starter works fine so will replace the brushes and freshen it up inside next winter.
